AN-1118 Eight Output 8-bit PCM LED Dimming Using ASM
This application note will explain how to create an eight output LED controller, each channel with 8-bit resolution PCM (Pulse Code Modulation), using little more than the ASM block in GPAK5. Furthermore, the I2C interface enables offloading LED driving functions from an MCU. Only a portion of GPAK5’s resources are needed in this implementation; many blocks are left available to implement other user functions.
