AN-1099 Using GreenPAK’s I2C Port to Control an RGB LED Pulse

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 on and off time for driving the R, G, and B cathodes of an LED. This creates a repetitive output pulse of light. It is important to note that any reconfigurations via I2C are volatile and will revert to the programmed code after the POR inside the GPAK resets.
