1.5 CE Compliance Equipment is generally divided into two classes. CLASS A
CLASS B
Digital equipment meant for light industrial use
Digital equipment meant for home use
Less restrictive emissions requirement: less than 40 dB µV/m at 10 m (40 dB relative to 1 µV/m) or 300 µV/m
More restrictive emissions requirement: 30 dB µV/m at 10 m or 100 µV/m
These limits apply over the range of 30–230 MHz. The limits are 7 dB higher for frequencies above 230 MHz. Although the test range goes to 1 GHz, the emissions from Rabbit-based systems at frequencies above 300 MHz are generally well below background noise levels. The BL2100 single-board computer has been tested and was found to be in conformity with the following applicable immunity and emission standards. The BL2110, BL2120, and BL2130 single-board computers are also CE qualified as they are sub-versions of the BL2100 singleboard computer. Boards that are CE-compliant have the CE mark. Immunity The BL2100 series of single-board computers meets the following EN55024/1998 immunity standards. • EN61000-4-3 (Radiated Immunity) • EN61000-4-4 (EFT) • EN61000-4-6 (Conducted Immunity) Additional shielding or filtering may be required for a heavy industrial environment. Emissions The BL2100 series of single-board computers meets the following emission standards with the Rabbit 2000 spectrum spreader turned on and set to the normal mode. The spectrum spreader is only available with Rev. C or higher of the Rabbit 2000 microprocessor. This microprocessor is used in all BL2100 series boards that carry the CE mark. • EN55022:1998 Class A • FCC Part 15 Class A NOTE: The BL2100 satisfied the Class A limits but not the Class B limits. Such equipment need not be restricted in its sale, but the following warning must be included in the instructions for its use. Warning This is a Class A product. In a domestic environment this product may cause radio interference, in which case the user may be required to take adequate measures.
Additional shielding or filtering may be needed to meet Class B emissions standards. 6

1.5.1 Design Guidelines Note the following requirements for incorporating a BL2100 series single-board computer into your application to comply with CE requirements. General • The power supply provided with the Tool Kit is for development purposes only. It is the customer’s responsibility to provide a CE-compliant power supply for the end-product application. • When connecting the BL2100 single-board computer to outdoor cables, the customer is responsible for providing CE-approved surge/lighting protection. • Rabbit recommends placing digital I/O or analog cables that are 3 m or longer in a metal conduit to assist in maintaining CE compliance and to conform to good cable design practices. • When installing or servicing the BL2100, it is the responsibility of the end-user to use proper ESD precautions to prevent ESD damage to the BL2100. Safety • All inputs and outputs to and from the BL2100 single-board computer must not be connected to voltages exceeding SELV levels (42.4 V AC peak, or 60 V DC). • The lithium backup battery circuit on the BL2100 single-board computer has been designed to protect the battery from hazardous conditions such as reverse charging and excessive current flows. Do not disable the safety features of the design. 1.5.2 Interfacing the BL2100 to Other Devices There are two versions of the LCD/keypad module that may be used with the BL2100: a plug-in version (Part No. 101-0465), and a remote panel-mounted version with bezel (Part No. 101-0502). The BL2100 with the LCD/keypad module plugged in may be regarded as a “maintenance unit” that conforms to the same CE standards as does the BL2100 alone, where the entire assembly is mounted inside an enclosure, and the enclosure is only opened to “tune up” the system. In addition, the cable for a panel-mounted LCD/keypad module should be less than 30 cm (12") to maintain CE compliance. Appendix C provides complete information for mounting and using the LCD/keypad module. Since the BL2100 single-board computers are designed to be connected to other devices, good EMC practices should be followed to ensure compliance. CE compliance is ultimately the responsibility of the integrator. Additional information, tips, and technical assistance are available from your authorized Rabbit distributor, and are also available on our Web site at www.rabbit.com.

Figure 3. Attach BL2100 Main Board to Plastic Enclosure Base
The plastic enclosure base facilitates handling the BL2100 during development, and provides an attractive mounting alternative. Alternatively, you may wish to use standoffs to protect the components on the other side of the board. The plastic enclosure base is offered as a separate option when individual BL2100 boards are purchased. NOTE: Appendix D, “Plastic Enclosure,” provides additional information and specifications for the plastic enclosure.

4. Connect the programming cable to download programs from your PC and to program and debug the BL2100. Connect the 10-pin PROG connector of the programming cable to header J1 on the BL2100 RabbitCore module. Ensure that the colored edge lines up with pin 1 as shown. (Do not use the DIAG connector, which is used for a nonprogramming serial connection.) Connect the other end of the programming cable to a COM port on your PC. Make a note of the port to which you connect the cable, as Dynamic C will need to have this parameter configured. Note that COM1 on the PC is the default COM port used by Dynamic C. +K2

5. Connect the power supply. First, prepare the AC adapter for the country where it will be used by selecting the plug. The BL2100 Tool Kit presently includes Canada/Japan/U.S., Australia/N.Z., U.K., and European style plugs. Snap in the top of the plug assembly into the slot at the top of the AC adapter as shown in Figure 5, then press down on the spring-loaded clip below the plug assembly to allow the plug assembly to click into place. Connect the bare ends of the power supply to the +RAW and GND positions on screwterminal header J5 (IDC header J4) as shown in Figure 6.
Figure 6. Power Supply Connections
6. Apply power. Plug in the AC adapter. If you are using your own power supply, it must provide 9 to 36 V DC (13 to 36 V DC if you intend to use the full range of the D/A converter outputs)—voltages outside this range could damage the BL2100. CAUTION: Unplug the power supply while you make or otherwise work with the connections to the headers. This will protect your BL2100 from inadvertent shorts or power spikes. NOTE: A hardware RESET is done by unplugging the AC adapter, then plugging it back in.

2.2 Installing Dynamic C If you have not yet installed Dynamic C version 7.06 (or a later version), do so now by inserting the Dynamic C CD in your PC’s CD-ROM drive. The CD will auto-install unless you have disabled auto-install on your PC. If the CD does not auto-install, click Start > Run from the Windows Start button and browse for the Dynamic C setup.exe file on your CD drive. Click OK to begin the installation once you have selected the setup.exe file. The installation program will guide you through the installation process. Most steps of the process are self-explanatory. Dynamic C uses a COM (serial) port to communicate with the target development system. The installation allows you to choose the COM port that will be used. The default selection is COM1. You may select any available port for Dynamic C’s use. If you are not certain which port is available, select COM1. This selection can be changed later within Dynamic C. Once your installation is complete, you will have up to three icons on your PC desktop. One icon is for Dynamic C, one opens the documentation menu, and the third is for the Rabbit Field Utility, a tool used to download precompiled software to a target system. If you have purchased the optional Dynamic C Rabbit Embedded Security Pack, install it after installing Dynamic C. You must install the Rabbit Embedded Security Pack in the same directory where Dynamic C was installed. The Dynamic C User’s Manual provides detailed instructions for the installation of Dynamic C and any future upgrades. NOTE: If you have an earlier version of Dynamic C already installed, the default installation of the later version will be in a different folder, and a separate icon will appear on your desktop.
14
Smartcat (BL2100)
2.3 Starting Dynamic C Once the BL2100 is connected to your PC and to a power source, start Dynamic C by doubleclicking on the Dynamic C icon on your desktop or in your Start menu. If you are using a USB port to connect your computer to the BL2100, choose Options > Project Options and select “Use USB to Serial Converter” under the Communications tab. Click OK.
2.4 Run a Sample Program Use the File menu to open the sample program PONG.C, which is in the Dynamic C SAMPLES folder. Press function key F9 to compile and run the program. The STDIO window will open on your PC and will display a small square bouncing around in a box. This program shows that the CPU is working. The sample program described in Section 5.2.3, “Run the PINGME.C Demo,” tests the TCP/IP portion of the board. 2.4.1 Troubleshooting If Dynamic C cannot find the target system (error message "No Rabbit Processor Detected."): • Check that the BL2100 is powered correctly — the AC adapter should be plugged in to the +RAW and GND positions on screw-terminal header J5 (IDC header J4). • Check both ends of the programming cable to ensure that they are firmly plugged into the PC and the PROG connector, not the DIAG connector, is plugged in to the programming port on the RabbitCore module with the marked (colored) edge of the programming cable towards pin 1 of the programming header. • Ensure that the RabbitCore module is firmly and correctly installed in its connectors on the BL2100 main board. • Dynamic C uses the COM port specified during installation. Select a different COM port within Dynamic C. From the Options menu, select Project Options, then select Communications. Select another COM port from the list, then click OK. Press to force Dynamic C to recompile the BIOS. If Dynamic C still reports it is unable to locate the target system, repeat the above steps until you locate the COM port used by the programming cable. If Dynamic C appears to compile the BIOS successfully, but you then receive a communication error message when you compile and load a sample program, it is possible that your PC cannot handle the higher program-loading baud rate. Try changing the maximum download rate to a slower baud rate as follows. • Locate the Serial Options dialog in the Dynamic C Options > Communications menu. Select a slower Max download baud rate.
User’s Manual
15
If a program compiles and loads, but then loses target communication before you can begin debugging, it is possible that your PC cannot handle the default debugging baud rate. Try lowering the debugging baud rate as follows. • Locate the Serial Options dialog in the Dynamic C Options > Communications menu. Choose a lower debug baud rate.
2.5 Where Do I Go From Here? If the sample program ran fine, you are now ready to go on to other sample programs and to develop your own applications. The source code for the sample programs is provided to allow you to modify them for your own use. The BL2100 User’s Manual also provides complete hardware reference information and describes the software function calls for the BL2100 and the optional LCD/keypad module.
For advanced development topics, refer to the Dynamic C User’s Manual and the Dynamic C TCP/IP User’s Manual, also in the online documentation set. 2.5.1 Technical Support NOTE: If you purchased your BL2100 through a distributor or Rabbit partner, contact the distributor or partner first for technical support.
If there are any problems at this point: • Use the Dynamic C Help menu to get further assistance with Dynamic C. • Check the Rabbit Technical Bulletin Board and forums at www.rabbit.com/support/bb/ and at www.rabbit.com/forums/. • Use the Technical Support e-mail form at www.rabbit.com/support/. If the sample program ran fine, you are now ready to go on to explore other BL2100 features and develop your own applications. Chapter 3, “Subsystems,” provides a description of the BL2100’s features, Chapter 4, “Software,” describes the Dynamic C software libraries and introduces some sample programs, and Chapter 5, “Using the TCP/IP Features,” explains the TCP/IP features.

3.2.2 Digital Outputs The BL2100 has 16 digital outputs, OUT00–OUT15, which can each sink or source up to 200 mA. Figure 11 shows a wiring diagram for using the digital outputs in a sinking or a souring configuration. All the digital outputs sink and source actively. They can be used as high-side drivers, low-side drivers, or as an H-bridge driver. When the BL2100 is first powered up or reset, all the outputs are disabled, that is, at a high-impedance status, until the digoutConfig software function call is made. The digoutConfig call sets the initial state of each digital output according to the configuration specified by the user, and enables the digital outputs to their initial status.

OUT00–OUT07 are powered by to +K1, and OUT08–OUT15 are powered by +K2. K1 and K2 can each be up to 36 V. They don't have to be same. All the sinking current, which could be up to 3.2 A, is returned through the GND pins. Be sure to use a suitably sized GND and keep the distance to the power supply as short as possible. Since there are two GND terminals (header J5/J4, and header J11/J10), it is User’s Manual
21
highly recommend that you split the GND returns according to the two banks of digital outputs.

For the H bridge, which is shown in Figure 12, K1 and K2 should be the same if two digital outputs used for the H bridge are on different banks.

3.3 Serial Communication The BL2100 has two RS-232 serial ports, which can be configured as one RS-232 serial channel (with RTS/CTS) or as two RS-232 (3-wire) channels using the serMode software function call. Table 2 summarizes the options. Table 2. Serial Communication Configurations Serial Port Mode B

RS-485
The BL2100 also has one RS-485 serial channel and one CMOS serial channel that serves as the programming port. All four serial ports operate in an asynchronous mode. An asynchronous port can handle 7 or 8 data bits. A 9th bit address scheme, where an additional bit is sent to mark the first byte of a message, is also supported. Serial Port A, the programming port, can be operated alternately in the clocked serial mode. In this mode, a clock line synchronously clocks the data in or out. Either of the two communicating devices can supply the clock. The BL2100 boards typically use all four ports in the asynchronous serial mode. Serial Ports B and C are used for RS-232 communication, and Serial Port D is used for RS-485 communication. The BL2100 uses an 11.0592 MHz crystal, which is doubled to 22.1184 MHz. At this frequency, the BL2100 supports standard asynchronous baud rates up to a maximum of 230,400 bps. 3.3.1 RS-232 The BL2100 RS-232 serial communication is supported by an RS-232 transceiver. This transceiver provides the voltage output, slew rate, and input voltage immunity required to meet the RS-232 serial communication protocol. Basically, the chip translates the Rabbit 2000’s CMOS/TTL signals to RS-232 signal levels. Note that the polarity is reversed in an RS-232 circuit so that a +5 V output becomes approximately -10 V and 0 V is output as +10 V. The RS-232 transceiver also provides the proper line loading for reliable communication. RS-232 can be used effectively at the BL2100’s maximum baud rate for distances of up to 15 m. 3.3.2 RS-485 The BL2100 has one RS-485 serial channel, which is connected to the Rabbit 2000 Serial Port D through an RS-485 transceiver. The half-duplex communication uses the Rabbit 2000’s PB6 pin to control the transmit enable on the communication line.

Figure 14. RS-485 Termination and Bias Resistors
For best performance, the bias and termination resistors in a multidrop network should only be enabled on both end nodes of the network. Disable the termination and bias resistors on any intervening BL2100 units in the network by removing both jumpers from header JP1. TIP: Save the jumpers for possible future use by “parking” them across pins 1–3 and 4–6 of header JP1. Pins 3 and 4 are not otherwise connected to the BL2100.

3.3.3 Ethernet Port Figure 15 shows the pinout for the Ethernet port (J2 on the BL2100 module). Note that there are two standards for numbering the pins on this connector—the convention used here, and numbering in reverse to that shown. Regardless of the numbering convention followed, the pin positions relative to the spring tab position (located at the bottom of the RJ-45 jack in Figure 15) are always absolute, and the RJ-45 connector will work properly with off-the-shelf Ethernet cables.

RJ-45 pinouts are sometimes numbered opposite to the way shown in Figure 15. Two LEDs are placed next to the RJ-45 Ethernet jack, one to indicate an Ethernet link (LNK) and one to indicate Ethernet activity (ACT). The transformer/connector assembly ground is connected to the BL2100 module printed circuit board digital ground via a 0 resistor “jumper,” R29, as shown in Figure 16.

The factory default is for the 0 resistor “jumper” at R29 to be installed. In high-noise environments, remove R29 and ground the transformer/connector assembly directly through the chassis ground. This will be especially helpful to minimize ESD and/or EMI problems.

3.3.4 Programming Port The RabbitCore module on the BL2100 has a 10-pin programming header. The programming port uses the Rabbit 2000’s Serial Port A for communication. Dynamic C uses the programming port to download and debug programs. The programming port is also used for the following operations. • Cold-boot the Rabbit 2000 on the RabbitCore module after a reset. • Remotely download and debug a program over an Ethernet connection using the RabbitLink EG2110. • Fast copy designated portions of flash memory from one Rabbit-based board (the master) to another (the slave) using the Rabbit Cloning Board. In addition to Serial Port A, the Rabbit 2000 startup-mode (SMODE0, SMODE1), status, and reset pins are available on the serial programming port. The two startup mode pins determine what happens after a reset—the Rabbit 2000 is either cold-booted or the program begins executing at address 0x0000. The status pin is used by Dynamic C to determine whether a Rabbit microprocessor is present. The status output has three different programmable functions: 1. It can be driven low on the first op code fetch cycle. 2. It can be driven low during an interrupt acknowledge cycle. 3. It can also serve as a general-purpose output. The /RESET_IN pin is an external input that is used to reset the Rabbit 2000 and the onboard peripheral circuits on the RabbitCore module. The serial programming port can be used to force a hard reset on the RabbitCore module by asserting the /RESET_IN signal. Alternate Uses of the Serial Programming Port
All three clocked Serial Port A signals are available as • a synchronous serial port • an asynchronous serial port, with the clock line usable as a general CMOS input The programming port may also be used as a serial port once the application is running. The SMODE pins may then be used as inputs and the status pin may be used as an output. Refer to the Rabbit 2000 Microprocessor User’s Manual for more information.

3.4 Programming Cable The programming cable is used to connect the programming port of the RabbitCore module to a PC serial COM port. The programming cable converts the RS-232 voltage levels used by the PC serial port to the TTL voltage levels used by the Rabbit 2000. When the PROG connector on the programming cable is connected to the RabbitCore module’s programming header, programs can be downloaded and debugged over the serial interface. The DIAG connector of the programming cable may be used on the programming header of the RabbitCore module with the module operating in the Run Mode. This allows the programming port to be used as a regular serial port. 3.4.1 Changing Between Program Mode and Run Mode The BL2100 is automatically in Program Mode when the PROG connector on the programming cable is attached to the RabbitCore module, and is automatically in Run Mode when no programming cable is attached. When the Rabbit 2000 is reset, the operating mode is determined by the status of the SMODE pins. When the programming cable’s PROG connector is attached, the SMODE pins are pulled high, placing the Rabbit 2000 in the Program Mode. When the programming cable’s PROG connector is not attached, the SMODE pins are pulled low, causing the Rabbit 2000 to operate in the Run Mode. Program Mode

3.5 A/D Converter Inputs The single 14-channel A/D converter chip used in the BL2100 has a resolution of 12 bits (models BL2100 and BL2120 only). Eleven of the 14 channels are available externally, and three are used internally for the reference voltages: 4.096 V (Vref), 2.048 V (Vref/2), and Analog Ground. These internal voltages can be used to check the functioning of the A/D converter chip. The A/D converter chip only measures voltages between 0 V and the applied reference voltage. Therefore, each external input has circuitry that provides scaling and buffering. All 11 external inputs are scaled and buffered to provide the user with an input impedance of 1 M and a range of -10.24 V to +10.24 V. Figure 18 shows the buffered A/D converter inputs.

Figure 18. Buffered A/D Converter Inputs
The op-amp is powered from the +V supply. The 1 M and 200 k resistors set the gain (scale factor), which is 0.2 in this case. This results in a dynamic input range of 0.2 × 20.48 V or 4.096 V. The center point of this range is set by the 1.707 V reference voltage. With the reference set to 1.707 V, the center point is at 0 V and the input voltage can range from -10.24 V to +10.24 V. To maintain the best accuracy, the input range should be limited to -10.0 V to +10.0 V. The A/D converter inputs are factory-calibrated and the calibration constants are stored in flash memory. You may calibrate the A/D converter inputs at a later time using the software functions described in Section 4.4.4, “A/D Converter Inputs.” The GETCALIB.C and the SAVECALIB.C sample programs in the Dynamic C SAMPLES\BL2100\ Calib_Save_Retrieve folder illustrate how to retrieve and save calibration data.

3.6 D/A Converter Outputs Only the BL2100 and the BL2120 models are stuffed with D/A converters. The D/A converter outputs are buffered and scaled to provide an output from 0 V to +10 V. NOTE: The D/A converter output voltage depends on the original power-supply voltage, +RAW, so if +RAW < 13 V, the maximum D/A converter output will be +RAW – 3 V.

This circuit generates the 4.096 V reference voltage, which is used by the A/D converter and by the D/A converters. This sets the operating range of the A/D converter and the D/A converters (0–10 V). To use the full accuracy of the A/D converter and the D/A converters, this voltage must be accurate to the same degree. The reference zener diode in combination with the 300 resistor form a shunt regulator. The 4.096 V reference voltage then feeds the A/D converter, the D/A converters, and the voltage divider composed of the 10 k and the 14 k resistors. The voltage divider generates a second reference voltage of 1.707 V to feed the four op-amps for the buffered A/D converter inputs. The 2.048 V reference voltage is also used to generate the 2.5 V reference for D-REF used in the digital output circuit.

3.8 Memory 3.8.1 SRAM The BL2100 module is designed to accept 128K to 512K of SRAM packaged in an SOIC case. The standard BL2100 modules come with 128K of SRAM. 3.8.2 Flash Memory The BL2100 is also designed to accept 128K to 512K of flash memory packaged in a TSOP case. The standard BL2100 modules comes with one 256K flash memory. NOTE: Rabbit recommends that any customer applications should not be constrained by the sector size of the flash memory since it may be necessary to change the sector size in the future.
A Flash Memory Bank Select jumper configuration option based on 0 surface-mounted resistors exists at header JP2 on the RabbitCore module. This option, used in conjunction with some configuration macros, allows Dynamic C to compile two different co-resident programs for the upper and lower halves of the 256K flash in such a way that both programs start at logical address 0000. This is useful for applications that require a resident download manager and a separate downloaded program. See Technical Note 218, Implementing a Serial Download Manager for a 256K Flash, for details.

In addition to its primary use as an external interrupt, pin 11 of screw-terminal header J11 may also be used as a CMOS-level digital input or output, or to generate a PWM signal. When using pin 11 as a CMOS-level digital input or output, use the standard Rabbit 2000 register function configuration for PE5 (on Parallel Port E) to set this pin up for your intended use. Be aware that there is no provision for protection against voltage spikes while PE5 is pulled up to Vcc with a 27 k pull-up resistor. The sample program PWM.C in the Dynamic C SAMPLES/BL2100 directory illustrates how to use pin 11 of screw-terminal header J11 to generate a PWM signal.

3.9.2 Clock Doubler The BL2100 takes advantage of the Rabbit 2000 microprocessor’s internal clock doubler. A built-in clock doubler allows half-frequency crystals to be used to reduce radiated emissions. The 22.1 MHz frequency is generated using an 11.0592 MHz crystal. The clock doubler is disabled automatically in the BIOS for crystals with a frequency above 12.9 MHz. The clock doubler may be disabled if 22.1 MHz clock speeds are not required. Disabling the Rabbit 2000 microprocessor’s internal clock doubler will reduce power consumption and further reduce radiated emissions. The clock doubler is disabled with a simple configuration macro as shown below. 1. Select the “Defines” tab from the Dynamic C Options > Project Options menu. 2. Add the line CLOCK_DOUBLED=0 to always disable the clock doubler. The clock doubler is enabled by default, and usually no entry is needed. If you need to specify that the clock doubler is always enabled, add the line CLOCK_DOUBLED=1 to always enable
the clock doubler. The clock speed will be doubled as long as the crystal frequency is less than or equal to 26.7264 MHz. 3. Click OK to save the macro. The clock doubler will now remain off whenever you are in the project file where you defined the macro.
3.9.3 Spectrum Spreader BL2100 boards that carry the CE mark on their RabbitCore module have a Rabbit 2000 microprocessor that features a spectrum spreader, which helps to mitigate EMI problems. By default, the spectrum spreader is on automatically for BL2100 boards that carry the CE mark when used with Dynamic C 7.30 or later versions, but the spectrum spreader may also be turned off or set to a stronger setting. The means for doing so is through a simple configuration macro as shown below. .
1. Select the “Defines” tab from the Dynamic C Options > Project Options menu. 2. Normal spreading is the default, and usually no entry is needed. If you need to specify normal spreading, add the line ENABLE_SPREADER=1
For strong spreading, add the line ENABLE_SPREADER=2
To disable the spectrum spreader, add the line ENABLE_SPREADER=0
NOTE: The strong spectrum-spreading setting is unnecessary for the BL2000. 3. Click OK to save the macro. The spectrum spreader will now be set to the state specified by the macro value whenever you are in the project file where you defined the macro.
There is no spectrum spreader functionality for BL2100 boards that do not carry the CE mark on their RabbitCore module or when using any BL2100 with a version of Dynamic C prior to 7.30. 34

4. SOFTWARE Dynamic C is an integrated development system for writing embedded software. It runs on an IBM-compatible PC and is designed for use with single-board computers and other devices based on the Rabbit microprocessor. Chapter 4 provides the libraries, function calls, and sample programs related to the BL2100. 4.1 Running Dynamic C You have a choice of doing your software development in the flash memory or in the static RAM included on the BL2100. The flash memory and SRAM options are selected with the Options > Compiler menu. The advantage of working in RAM is to save wear on the flash memory, which is limited to about 100,000 write cycles. The disadvantage is that the code and data might not both fit in RAM. NOTE: An application can be developed in RAM, but cannot run standalone from RAM after the programming cable is disconnected. Standalone applications can only run from flash memory. NOTE: Do not depend on the flash memory sector size or type. Due to the volatility of the flash memory market, the BL2100 and Dynamic C were designed to accommodate flash devices with various sector sizes.
BL2100s that are special-ordered with 512K flash/512K SRAM memory options have two 256K flash memories. By default, Dynamic C will use only the first flash memory for program code in these BL2100s. Uncomment the USE_2NDFLASH_CODE macro within the RABBITBIOS.C file in the Dynamic C BIOS folder to allow the second flash memory to hold any program code that is in excess of the available memory in the first flash.

Developing software with Dynamic C is simple. Users can write, compile, and test C and assembly code without leaving the Dynamic C development environment. Debugging occurs while the application runs on the target. Alternatively, users can compile a program to an image file for later loading. Dynamic C runs on PCs under Windows 2000 and later—see Rabbit’s Technical Note TN257, Running Dynamic C® With Windows Vista®, for additional information if you are using a Dynamic C release prior to v. 9.60 under Windows Vista. Programs can be downloaded at baud rates of up to 460,800 bps after the program compiles. Dynamic C has a number of standard features. • Full-feature source and/or assembly-level debugger, no in-circuit emulator required. • Royalty-free TCP/IP stack with source code and most common protocols. • Hundreds of functions in source-code libraries and sample programs: Exceptionally fast support for floating-point arithmetic and transcendental functions. RS-232 and RS-485 serial communication. Analog and digital I/O drivers. I2C, SPI, GPS, file system. LCD display and keypad drivers.
• Powerful language extensions for cooperative or preemptive multitasking • Loader utility program to load binary images into Rabbit-based targets in the absence of Dynamic C. • Provision for customers to create their own source code libraries and augment on-line help by creating “function description” block comments using a special format for library functions. • Execution tracing and symbolic stack tracing. • Standard debugging features: Breakpoints—Set breakpoints that can disable interrupts. Single-stepping—Step into or over functions at a source or machine code level, µC/OS-II aware. Code disassembly—The disassembly window displays addresses, opcodes, mnemonics, and machine cycle times. Switch between debugging at machine-code level and source-code level by simply opening or closing the disassembly window. Watch expressions—Watch expressions are compiled when defined, so complex expressions including function calls may be placed into watch expressions. Watch expressions can be updated with or without stopping program execution. Register window—All processor registers and flags are displayed. The contents of general registers may be modified in the window by the user. Stack window—shows the contents of the top of the stack. Hex memory dump—displays the contents of memory at any address. STDIO window—printf outputs to this window and keyboard input on the host PC can be detected for debugging purposes. printf output may also be sent to a serial port or file. 36

4.1.1 Upgrading Dynamic C 4.1.1.1 Patches and Bug Fixes
Dynamic C patches that focus on bug fixes are available from time to time. Check our Web site www.rabbit.com/support/ for the latest patches, workarounds, and bug fixes. The default installation of a patch or bug fix is to install the file in a directory (folder) different from that of the original Dynamic C installation. Rabbit recommends using a different directory so that you can verify the operation of the patch without overwriting the existing Dynamic C installation. If you have made any changes to the BIOS or to libraries, or if you have programs in the old directory (folder), make these same changes to the BIOS or libraries in the new directory containing the patch. Do not simply copy over an entire file since you may overwrite a bug fix; of course, you may copy over any programs you have written. Once you are sure the new patch works entirely to your satisfaction, you may retire the existing installation, but keep it available to handle legacy applications. 4.1.2 Extras Dynamic C installations are designed for use with the board they are included with, and are included at no charge as part of our low-cost kits. Starting with Dynamic C version 9.60, Dynamic C includes the popular µC/OS-II realtime operating system, point-to-point protocol (PPP), FAT file system, RabbitWeb, and other select libraries. Rabbit also offers for purchase the Rabbit Embedded Security Pack featuring the Secure Sockets Layer (SSL) and a specific Advanced Encryption Standard (AES) library. In addition to the Web-based technical support included at no extra charge, a one-year telephone-based technical support subscription is also available for purchase. Visit our Web site at www.rabbit.com for further information and complete documentation.

4.4.2 Digital I/O
void digOutConfig(unsigned int outputMode); Each of the BL2100 high-current outputs (OUT00–OUT15) has the capability of being configured in software as either sinking or sourcing using the digOutConfig function. Execute digOutConfig at the start of your application to initially set OUT00–OUT15 to be OFF for the type of circuit that you have, either sinking or sourcing. To properly set the high-current outputs, you will need to decide for each channel whether the output is sinking or sourcing. The digOutConfig function will then ensure that each output remains OFF when the digital output control interface is initialized. The individual high-current outputs remain activated until you activate the desired output driver(s)/channel(s) using digOut. NOTE: The brdInit function must be executed before calling digOutConfig. NOTE: You must execute the digOutConfig function to set the high-current drivers to be either sinking or sourcing. A runtime error will occur in digOut if digOutConfig has not executed. NOTE: The extra digital outputs resulting from the reconfiguration of IN16–IN23 as digital outputs are sinking outputs only and cannot be configured with digOutConfig. PARAMETER
outputMode is a 16-bit parameter where each bit corresponds to one of the following high-current outputs. Bit 15 = high-current output channel OUT15 Bit 14 = high-current output channel OUT14 Bit 13 = high-current output channel OUT13 Bit 12 = high-current output channel OUT12 Bit 11 = high-current output channel OUT11 Bit 10 = high-current output channel OUT10 Bit 9 = high-current output channel OUT09 Bit 8 = high-current output channel OUT08 Bit 7 = high-current output channel OUT07 Bit 6 = high-current output channel OUT06 Bit 5 = high-current output channel OUT05 Bit 4 = high-current output channel OUT04 Bit 3 = high-current output channel OUT03 Bit 2 = high-current output channel OUT02 Bit 1 = high-current output channel OUT01 Bit 0 = high-current output channel OUT00 The high-current outputs can be configured to be sinking or sourcing outputs by setting the corresponding bit to an 0 or 1: 0 = sinking, 1 = sourcing.

4.4.3 Serial Communication Library files included with Dynamic C provide a full range of serial communications support. The RS232.LIB library provides a set of circular-buffer-based serial functions. The PACKET.LIB library provides packet-based serial functions where packets can be delimited by the 9th bit, by transmission gaps, or with user-defined special characters. Both libraries provide blocking functions, which do not return until they are finished transmitting or receiving, and nonblocking functions, which must be called repeatedly until they are finished. For more information, see the Dynamic C User’s Manual and Technical Note 213, Rabbit Serial Port Software. Use the following function calls with the BL2100.
int serMode(int mode); User interface to set up BL2100 serial communication lines. Call this function after serXOpen(). Whether you are opening one or multiple serial ports, this function must be executed after executing the last serXOpen function AND before you start using any of the serial ports. This function is non-reentrant. If Mode 1 is selected, CTS/RTS flow control is exercised using the serCflowcontrolOn and serCflowcontrolOff functions from the RS232.LIB library. PARAMETER

5. USING THE TCP/IP FEATURES Chapter 5 discusses using the TCP/IP features on the BL2100 and BL2110 boards. The TCP/IP feature is not available on BL2120 and BL2130 versions. 5.1 TCP/IP Connections Before proceeding you will need to have the following items. • If you don’t have Ethernet access, you will need at least a 10Base-T Ethernet card (available from your favorite computer supplier) installed in a PC. • Two RJ-45 straight through Ethernet cables and a hub, or an RJ-45 crossover Ethernet cable. The Ethernet cables and Ethernet hub are available from Rabbit in a TCP/IP tool kit. More information is available at www.rabbit.com. 1. Connect the AC adapter and the programming cable as shown in Chapter 2, “Getting Started.” 2. Ethernet Connections If you do not have access to an Ethernet network, use a crossover Ethernet cable to connect the BL2100 to a PC that at least has a 10Base-T Ethernet card. If you have Ethernet access, use a straight through Ethernet cable to establish an Ethernet connection to the BL2100 from an Ethernet hub. These connections are shown in Figure 23. BL2100 Board

The PC running Dynamic C through the serial programming port on the BL2100 does not need to be the PC with the Ethernet card. 3. Apply Power Plug in the AC adapter. The BL2100 is now ready to be used. NOTE: A hardware RESET is accomplished by unplugging the AC adapter, then plugging it back in, or by momentarily grounding the board reset input at pin 9 on screwterminal header J2.
When working with the BL2100, the green LNK light is on when a program is running and the board is properly connected either to an Ethernet hub or to an active Ethernet card. The orange ACT light flashes each time a packet is received.

Smartcat (BL2100)
5.2 TCP/IP Sample Programs We have provided a number of sample programs demonstrating various uses of TCP/IP for networking embedded systems. These programs require that you connect your PC and the BL2100 together on the same network. This network can be a local private network (preferred for initial experimentation and debugging), or a connection via the Internet. 5.2.1 How to Set IP Addresses in the Sample Programs With the introduction of Dynamic C 7.30 we have taken steps to make it easier to run many of our sample programs. You will see a TCPCONFIG macro. This macro tells Dynamic C to select your configuration from a list of default configurations. You will have three choices when you encounter a sample program with the TCPCONFIG macro. 1. You can replace the TCPCONFIG macro with individual MY_IP_ADDRESS, MY_NETMASK, MY_GATEWAY, and MY_NAMESERVER macros in each program. 2. You can leave TCPCONFIG at the usual default of 1, which will set the IP configurations to 10.10.6.100, the netmask to 255.255.255.0, and the nameserver and gateway to 10.10.6.1. If you would like to change the default values, for example, to use an IP address of 10.1.1.2 for the BL2100 board, and 10.1.1.1 for your PC, you can edit the values in the section that directly follows the “General Configuration” comment in the TCP_CONFIG.LIB library. You will find this library in the LIB\TCPIP directory. 3. You can create a CUSTOM_CONFIG.LIB library and use a TCPCONFIG value greater than 100. Instructions for doing this are at the beginning of the TCP_CONFIG.LIB library in the LIB\TCPIP directory. There are some other “standard” configurations for TCPCONFIG that let you select different features such as DHCP. Their values are documented at the top of the TCP_CONFIG.LIB library in the LIB\TCPIP directory. More information is available in the Dynamic C TCP/IP User’s Manual. IP Addresses Before Dynamic C 7.30 Most of the sample programs use macros to define the IP address assigned to the board and the IP address of the gateway, if there is a gateway. Instead of the TCPCONFIG macro, you will see a MY_IP_ADDRESS macro and other macros. #define #define #define #define
MY_IP_ADDRESS "10.10.6.170" MY_NETMASK "255.255.255.0" MY_GATEWAY "10.10.6.1" MY_NAMESERVER "10.10.6.1"
In order to do a direct connection, the following IP addresses can be used for the BL2100: #define MY_IP_ADDRESS "10.1.1.2" #define MY_NETMASK "255.255.255.0" // #define MY_GATEWAY "10.10.6.1" // #define MY_NAMESERVER "10.10.6.1"
In this case, the gateway and nameserver are not used, and are commented out. The IP address of the board is defined to be 10.1.1.2. The IP address of you PC can be defined as 10.1.1.1. User’s Manual
57
5.2.2 How to Set Up Your Computer for Direct Connect Follow these instructions to set up your PC or notebook. Check with your administrator if you are unable to change the settings as described here since you may need administrator privileges. The instructions are specifically for Windows 2000, but the interface is similar for other versions of Windows. TIP: If you are using a PC that is already on a network, you will disconnect the PC from that network to run these sample programs. Write down the existing settings before changing them to facilitate restoring them when you are finished with the sample programs and reconnect your PC to the network.
1. Go to the control panel (Start > Settings > Control Panel), and then double-click the Network icon. 2. Select the network interface card used for the Ethernet interface you intend to use (e.g., TCP/IP Xircom Credit Card Network Adapter) and click on the “Properties” button. Depending on which version of Windows your PC is running, you may have to select the “Local Area Connection” first, and then click on the “Properties” button to bring up the Ethernet interface dialog. Then “Configure” your interface card for a “10Base-T Half-Duplex” or an “Auto-Negotiation” connection on the “Advanced” tab. NOTE: Your network interface card will likely have a different name.
3. Now select the IP Address tab, and check Specify an IP Address, or select TCP/IP and click on “Properties” to assign an IP address to your computer (this will disable “obtain an IP address automatically”): IP Address : 10.10.6.101 Netmask : 255.255.255.0 Default gateway : 10.10.6.1
4. Click or to exit the various dialog boxes. BL2100 Board

5.2.3 Run the PINGME.C Demo Connect the crossover cable from your computer’s Ethernet port to the BL2100’s RJ-45 Ethernet connector. Open this sample program from the SAMPLES\TCPIP\ICMP folder, compile the program, and start it running under Dynamic C. When the program starts running, the green LNK light on the BL2100 should be on to indicate an Ethernet connection is made. (Note: If the LNK light does not light, you may not have a crossover cable, or if you are using a hub perhaps the power is off on the hub.) The next step is to ping the board from your PC. This can be done by bringing up the MSDOS window and running the ping program: ping 10.10.6.100
or by Start > Run and typing the command ping 10.10.6.100
Notice that the orange ACT light flashes on the BL2100 while the ping is taking place, and indicates the transfer of data. The ping routine will ping the board four times and write a summary message on the screen describing the operation.

5.2.4 Running More Demo Programs With a Direct Connection The program SSI.C (SAMPLES\BL2100\TCPIP\) demonstrates how to make the BL2100 a Web server. This program allows you to turn the LEDs on an attached Demonstration Board from the Tool Kit on and off from a remote Web browser. LED0 and LED1 on the LCD/keypad module (LED1 and LED2 on the Demonstration Board) will match those on the Web page. As long as you have not modified the TCPCONFIG 1 macro in the sample program, enter the following server address in your Web browser to bring up the Web page served by the sample program. http://10.10.6.100. Otherwise use the TCP/IP settings you entered in the TCP_CONFIG.LIB library. The sample program SMTP.C (SAMPLES\BL2100\TCPIP\) allows you to send an E-mail when a switch on the Demonstration Board is pressed. Follow the instructions included with the sample program. The sample program TELNET.C (SAMPLES\BL2100\TCPIP\) allows you to communicate with the BL2100 using the Telnet protocol. This program takes anything that comes in on a port and sends it out Serial Port B. It uses digital input IN00 to indicate that the TCP/IP connection should be closed, and it uses high-current output OUT00 to indicate that there is an open connection. You may change the digital input and output to suit your application needs. Run the Telnet program on your PC (Start > Run telnet 10.10.6.100). As long as you have not modified the TCPCONFIG 1 macro in the sample program, the IP address is 10.10.6.100 as shown; otherwise use the TCP/IP settings you entered in the TCP_CONFIG.LIB library. Each character you type will be printed in Dynamic C's STDIO window, indicating that the board is receiving the characters typed via TCP/IP.
5.3 Where Do I Go From Here? NOTE: If you purchased your BL2100 through a distributor or Rabbit partner, contact the distributor or partner first for technical support.
If there are any problems at this point: • Use the Dynamic C Help menu to get further assistance with Dynamic C. • Check the Rabbit Technical Bulletin Board and forums at www.rabbit.com/support/bb/ and at www.rabbit.com/forums/. • Use the Technical Support e-mail form at www.rabbit.com/support/. If the sample programs ran fine, you are now ready to go on. If the sample programs ran fine, you are now ready to go on. Additional sample programs are described in the Dynamic C TCP/IP User’s Manual. Refer to the Dynamic C TCP/IP User’s Manual to develop your own applications. An Introduction to TCP/IP provides background information on TCP/IP, and is available on our Web site. 60

It is recommended that you allow for an “exclusion zone” of 0.25" (6 mm) around the BL2100 in all directions when the BL2100 is incorporated into an assembly that includes other components. This “exclusion zone” that you keep free of other components and boards will allow for sufficient air flow, and will help to minimize any electrical or EMI interference between adjacent boards. An “exclusion zone” of 0.12" (3 mm) is recommended below the BL2100. Figure A-2 shows this “exclusion zone.”

APPENDIX B. POWER SUPPLY Appendix B describes the power circuitry provided on the BL2100. B.1 Power Supplies Power is supplied to the BL2100 via header J5/J4. The BL2100 is protected against reverse polarity by a diode at D1 as shown in Figure B-1.

Figure B-1. BL2100 Power Supply
The input voltage range is from 9 V to 36 V. A switching power regulator is used to provide a Vcc of +5 V for the BL2100 logic circuits. Vcc is not accessible to the user. The digital ground and the analog ground share a single split ground plane on the board, with the analog ground connected at a single point to the digital ground by a 0 resistor (R29). This is done to minimize digital noise in the analog circuits and to eliminate the possibility of ground loops. External connections to analog ground are made on header J2/J1, and external connections to digital ground are made on headers J5/J4 and J11/J10. B.1.1 Power for Analog Circuits Power to the analog circuits is provided by way of a two-stage low-pass filter, which isolates the analog section from digital noise generated by the other components. The analog power voltage +V powers the op-amp for the buffered A/D converter inputs, the A/D converter, the D/A converter, and the 4.096 V reference circuit. The maximum current draw on +V is less than 10 mA. +V is not accessible to the user.

B.2 Batteries and External Battery Connections The SRAM and the real-time clock have battery backup. Power to the SRAM and the realtime clock (VRAM) is provided by two different sources, depending on whether the main part of the BL2100 is powered or not. When the BL2100 is powered normally, and Vcc is within operating limits, the SRAM and the real-time clock are powered from Vcc. If power to the board is lost or falls below 4.63 V, the VRAM and real-time clock power will come from the battery. The reset generator circuit controls the source of power by way of its /RESET output signal. A replaceable 265 mA·h lithium battery provides power to the real-time clock and SRAM when external power is removed from the circuit board. The drain on the battery is typically less than 10 µA when there is no external power applied to the BL2100, and so the expected shelf life of the battery is
265 mA·h ------------------------ = 3.0 years. 10 µA The drain on the battery is typically less than 4 µA when external power is applied, and so the expected BL2100 battery in-service life is
265 mA·h ------------------------ = 7.5 years. 4 µA A long-life 950 mA·h solder-in battery is also provided for in the board layout.

B.2.1 Replacing the Backup Battery The battery is user-replaceable, and is fitted in a battery holder. To replace the battery, lift up on the spring clip and slide out the old battery. Use only a Panasonic CR2330 or equivalent replacement battery, and insert it into the battery holder with the + side facing up. NOTE: The SRAM contents and the real-time clock settings will be lost if the battery is replaced with no power applied to the BL2100. Exercise care if you replace the battery while external power is applied to the BL2100. CAUTION: There is an explosion danger if the battery is short-circuited, recharged, or replaced incorrectly. Replace the battery only with the same type or an equivalent type recommended by the battery manufacturer. Dispose of used batteries according to the battery manufacturer’s instructions.

Figure B-2. BL2100 Backup Battery Circuit
The battery-backup circuit serves three purposes: • It reduces the battery voltage to the SRAM and to the real-time clock, thereby limiting the current consumed by the real-time clock and lengthening the battery life. • It ensures that current can flow only out of the battery to prevent charging the battery. • A voltage, VOSC, is supplied to U6, which keeps the 32.768 kHz oscillator working when the voltage begins to drop. VRAM and Vcc are nearly equal (<100 mV, typically 10 mV) when power is supplied to the BL2100. User’s Manual
75
B.2.3 Power to VRAM Switch The VRAM switch on the BL2100 module, shown in Figure B-3, allows the battery backup to provide power when the external power goes off. The switch provides an isolation between Vcc and the battery when Vcc goes low. This prevents the Vcc line from draining the battery. VCC

Figure B-3. VRAM Switch
Field-effect transistor Q5 is needed to provide a very small voltage drop between Vcc and VRAM (<100 mV, typically 10 mV) so that the board components powered by Vcc will not have a significantly different voltage than VRAM. When the BL2100 is not in reset, the /RESET line will be high. This turns on Q2, causing its collector to go low. This turns on Q5, allowing VRAM to nearly equal Vcc. When the BL2100 is in reset, the /RESET line will go low. This turns off Q2 and Q5, providing an isolation between Vcc and VRAM. B.2.4 Reset Generator The BL2100 module uses a reset generator on the module, U1, to reset the Rabbit 2000 microprocessor when the voltage drops below the voltage necessary for reliable operation. The reset occurs between 4.50 V and 4.75 V, typically 4.63 V.

Figure B-4. Chip Select Circuit
The current drain on the battery in a battery-backed circuit must be kept at a minimum. When the BL2100 is not powered, the battery keeps the SRAM memory contents and the real-time clock (RTC) going. The SRAM has a powerdown mode that greatly reduces power consumption. This powerdown mode is activated by raising the chip select (CS) signal line. Normally the SRAM requires Vcc to operate. However, only 2 V is required for data retention in powerdown mode. Thus, when power is removed from the circuit, the battery voltage needs to be provided to both the SRAM power pin and to the CS signal line. The CS control circuit accomplishes this task for the SRAM’s chip select signal line. In a powered-up condition, the CS control circuit must allow the processor’s chip select signal /CS1 to control the SRAM’s CS signal /CSRAM. So, with power applied, /CSRAM must be the same signal as /CS1, and with power removed, /CSRAM must be held high (but only needs to be battery voltage high). Q3 and Q4 are MOSFET transistors with complementary polarity. They are both turned on when power is applied to the circuit. They allow the CS signal to pass from the processor to the SRAM so that the processor can periodically access the SRAM. When power is removed from the circuit, the transistors will turn off and isolate /CSRAM from the processor. The isolated /CSRAM line has a 100 k pullup resistor to VRAM (R28). This pullup resistor keeps /CSRAM at the VRAM voltage level (which under no power condition is the backup battery’s regulated voltage at a little more than 2 V). Transistors Q3 and Q4 are of opposite polarity so that a rail-to-rail voltage can be passed. When the /CS1 voltage is low, Q3 will conduct. When the /CS1 voltage is high, Q4 conducts. It takes time for the transistors to turn on, creating a propagation delay. This propagation delay is typically very small, about 10 ns to 15 ns. User’s Manual

C.2 Contrast Adjustments for All Boards Starting in 2005, LCD/keypad modules were factory-configured to optimize their contrast based on the voltage of the system they would be used in. Be sure to select a KDU5V LCD/keypad module for use with the BL2100 — these modules operate at 5 V. You may adjust the contrast using the potentiometer at R2 as shown in Figure C-3. LCD/keypad modules configured for 3.3 V should not be used with the BL2100 because the higher voltage will reduce the backlight service life dramatically.

C.5.1 Programming Cable Tips Once the LCD/keypad module is in place on the BL2100, it is not possible to remove or attach the programming cable to/from the BL2100 programming port. You will have to remove, or at least lift up, the LCD/keypad module while you connect or disconnect the programming cable. While you are developing your application, you may wish to connect or disconnect the programming cable when resetting the BL2100 and switching between the Program Mode and the Run Mode. To avoid the inconvenience of removing and replacing the LCD/keypad module each time, the programming cable may be disconnected/reconnected at the RS-232/CMOS level converter in the middle of the programming cable. 1.

The following sample programs, found in the SAMPLES/LCD_Keypad/122x32_1x7/ TCPIP folder, are targeted at the Ethernet-enabled versions of the BL2100, the BL2100 and the BL2110. Remember to configure the IP address, netmask, and gateway as indicated in the sample programs. • MBOXDEMO.C—This program implements a web server that allows e-mail messages to be entered that are then shown on the LCD display. The keypad allows you to scroll within messages, flip to other e-mails, mark messages as read, and delete e-mails. When a new e-mail arrives, an LED turns on, and turns off once the message has been marked as read. A log of all e-mail actions is kept, and can be displayed in the Web browser. All current e-mails can also be read with the Web browser. When using MBOXDEMO.C, connect the BL2100 and a PC (or other device with a Web Browser) to an Ethernet. If you connect the PC and the BL2100 directly, be sure to use a crossover Ethernet cable; strait-through Ethernet cables and a hub may be used instead. • TCP_RESPOND.C—This program and TCP_SEND.C are executed on two separate single-board computers to demonstrate how the two boards communicate with each other. Use PCSEND.EXE on the PC console side at the command prompt if you do not have a second board. PCSEND.EXE is located with source code in the SAMPLES/ LCD_Keypad/Windows directory. TCP_RESPOND.C waits for a message from another single-board computer. The mes-
sage received is displayed on the LCD, and you may respond by pressing a key on the keypad. The response is then sent to the remote single-board computer. • TCPSEND.C—This program and TCP_RESPOND.C are executed on two separate singleboard computers to demonstrate how the two boards communicate with each other. Use PCRESPOND.EXE on the PC console side at the command prompt if you do not have a second board. PCRESPOND.EXE is located with source code in the SAMPLES/ LCD_Keypad/Windows directory. When a key on the keypad is pressed, a message associated with that key is sent to a specified destination address and port. The destination then responds to that message. The response is displayed on the LCD. Note that only the LEFT and UP scroll keys are set up to cause a message to be sent. When using TCPSEND.C and TCP_RESPOND.C, connect the BL2100 and the other singleboard computer to an Ethernet. If you connect the them directly, be sure to use a crossover Ethernet cable; strait-through Ethernet cables and a hub may be used instead.

int TextWindowFrame(windowFrame *window, fontInfo *pFont, int x, int y, int winWidth, int winHeight) Defines a text-only display window. This function provides a way to display characters within the text window using only character row and column coordinates. The text window feature provides end-of-line wrapping and clipping after the character in the last column and row is displayed.
NOTE: Execute the TextWindowFrame function before other Text... functions. PARAMETERS
*window is a window frame descriptor pointer. *pFont is a font descriptor pointer. x is the x coordinate of the top left corner of the text window frame. y is the y coordinate of the top left corner of the text window frame. winWidth is the width of the text window frame. winHeight is the height of the text window frame. RETURN VALUE
0—window frame was successfully created. -1—x coordinate + width has exceeded the display boundary. -2—y coordinate + height has exceeded the display boundary.

void TextPutChar(struct windowFrame *window, char ch); Displays a character on the display where the cursor is currently pointing. If any portion of a bitmap character is outside the LCD display area, the character will not be displayed. The cursor increments its position as needed.
NOTE: Execute the TextWindowFrame function before using this function. PARAMETERS
*window is a pointer to a font descriptor. ch is a character to be displayed on the LCD. RETURN VALUE
None. SEE ALSO TextGotoXY, TextPrintf, TextWindowFrame, TextCursorLocation
void TextPrintf(struct windowFrame *window, char *fmt, ...); Prints a formatted string (much like printf) on the LCD screen. Only printable characters in the font set are printed, also escape sequences, '\r' and '\n' are recognized. All other escape sequences will be skipped over; for example, '\b' and 't' will print if they exist in the font set, but will not have any effect as control characters. The text window feature provides end-of-line wrapping and clipping after the character in the last column and row is displayed. The cursor then remains at the end of the string.
NOTE: Execute the TextWindowFrame function before using this function. PARAMETERS
*window is a pointer to a font descriptor. *fmt is a formatted string. ... are formatted string conversion parameter(s). EXAMPLE TextPrintf(&TextWindow, "Test %d\n", count); RETURN VALUE

APPENDIX D. PLASTIC ENCLOSURE The plastic enclosure provides a secure way to protect your BL2100. The enclosure itself may be mounted on any flat surface. The complete plastic enclosure consists of a base and a cover. The base alone is a convenient surface on which to mount the BL2100, and also provides a means to mount the BL2100 on any flat surface. The base and cover are sold together with an LCD/keypad module that plugs into the main BL2100 board (Part No. 101-0466). Appendix D describes how to mount the BL2100 and the LCD/keypad inside the plastic enclosure, and provides details on mounting the assembly.
