AN-1098 Using GreenPAK's I2C Port to Control an RGB LED's Color

This app note explains how to reconfigure the SLG46531’s registers via I2C. Specifically, it shows how to change the registers associated with counters that set the PWM values for driving the R, G, and B cathodes of an LED. It is important to note that any reconfigurations via I2C are volatile and will revert to the programmed code after POR inside the GPAK resets.
