2. UART COMMUNICATION SPEC First: Write Command 1: Write key Cmd type =
0xA5:
Key
Cmd type(0xA5)
0x2A
Check sum
Check sum = byte0(Cmd type) + byte1(such as key)+byte2(such as 0x2A) Ex: power key code = 0x8A
0xA5
0x8A
0x2A
Data 0
Data1
0x59(check sum)
2: Write program number Cmd type = 0xA6:
Cmd type(0xA6)
Check sum
Data0 = Program number High Byte Data1 = Program number Low Byte Check sum = byte0(Cmd type) + Data0+Data1 Ex: Write program number: 518 = 0x206
0xA6
0x02
0x06
0xAE(check sum)
Second: Read Command Send to dvb module: Cmd type = 0xB3: Read
Cmd type(0xB3)
Data type
0
Check sum
Data(0..5)
Check sum
Data type: A certain kind of datas, see below Echo bytes from dvb module:
Cmd type(0xB3)
Data type
Check sum = 0xb3+Data type + Data0+Data1+Data2+Data3+Data4+Data5 Ex: To read program number, for example: current dvb program number is 342 (=0x0156), strength=0x4d, Quality = 0x2b, send the command as below:
B3
0
0
B3
DVB module should return the data as below:
0xB3
0
0
0x01
0x56
0
0x4d
0x2b
0x82
(Attention: you will receive many bytes, including the bytes you need, so, you should drop the junk bytes. How to get useful data? The correct data start at b3 00, and the checksum is important, too.)
