STEVAL-ILL011V1
RGB color control board based on ST72264G2 and STP08C596A
for LCD backlighting
Data Brief
Features
■ RS232 interface
■ Manual color setting
■ 7.5 to 30 V power supply
■ LED mode indicator
Description
The STEVAL-ILL011V1 evaluation board is based
on the ST72F264G2 microcontroller which
processes the ambient light color information
detected by the VM6101 ambient light sensor, and
reproduces the color using the STP8C596A RGB
LED driver. The evaluation kit software enables
operation in six different light-sensing modes,
including a power-saving mode where the
backlight intensity adapts to the ambient light
level.
