r P e
This system can be operated along with the STMPE24M31 based touch panel or the mechanical keys.
t e l o
The objective of this demo board is to demonstrate the features of the STLED325 LED controller driver, such as key scanning, RTC, IR decoding, STANDBY management, etc., as well as features of the advanced S-Touch device STMPE24M31 to fit the market segment of DVD players, DVD recorders, set-top boxes, washing machines and many more, keeping the system cost as low as possible.
s b O
The system can be operated using the various touch keys or mechanical front panel keys provided on the system, as well as from a remote control. System I/O is handled completely by STLED325 and STMPE24M31 with minimal load on the host processor. The system can be operated in two modes: touch interface mode or standalone mode (with mechanical keys on STEVAL-ILL029V2). On power-up, the system automatically detects the presence of the touch interface daughter card (STEVAL-CBP007V1) and goes into touch interface mode. If there is no touch card plugged in, the system enters into standalone mode and can be operated using mechanical keys. The STEVAL-CBP007V1 is included in the kit.
