基于STLED325和STMPE24M31的前向面板演示板
demo board shows the operation of front panel demonstration board based on the advanced LED controller driver STLED325 and 8bit microcontroller STM8S as I2C master. This system can be operated along with the STMPE24M31 based touch panel or the mechanical keys. 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. 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.
