STEVAL-ILL029V2演示板的目的是展示STLED325 LED控制器驱动程序的功能，如按键扫描， RTC ， IR解码，待机管理等，以及先进的S - Touch设备STMPE24M31以适应DVD播放器， DVD刻录机，机顶盒，洗衣机等细分市场，保持了系统的成本尽可能低的特征。This document explains the operation of the front panel demonstration board based on the advanced LED controller driver STLED325 and 8-bit microcontroller STM8S as I2C master.This system can be operated along with the STMPE24M31-based touch panel or the mechanical keys. The objective of this 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, etc., keeping the system cost as low as possible.The system can be operated using the various touchkeys or mechanical front panel keys provided on the system, as well as by 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 standalone mode and can be operated using mechanical keys.
