Writing a Pisound Driver


I’m working on an audio-focused OS targeting the pi as a personal project. I’d like to write a driver for the Pisound. Are there any resources other than the existing linux driver that would be helpful? The only thing I care about to begin with is audio output (not input or MIDI).


The Linux driver shows everything. :slight_smile: Keep in mind that the pisound-overlay.dts and pisound.c has Pisound specific bits, while the rest of the heavy lifting happens in ALSA sources, bcm2835-i2s.c and related files.
