STEVAL-ILL029V1
Description
The STEVAL-ILL029V1 front panel demonstration
board provides an evaluation platform for the
STLED325 advanced LED controller driver, and
the STM8S 8-bit microcontroller as I2C master.
The features of the STLED325 that this front
panel application demonstrates include key
scanning, RTC, IR decoding, and standby
management. These features are required to
address the market segment for DVD players,
DVD recorders, set-top boxes, washing machines
and many others, while keeping system costs as
low as possible.
The system can be operated using the front panel
keys mounted on the board, or by remote control.
System I/Os are handled completely by the
STLED325, with minimal load on the host
processor.
