Hey folks, building a proffie based 2 button prop that will not be using the onboard speaker out at all, I have a separate amp with a 3.5mm input jack, looking to use either a small I2S DAC ( PCM5102A) or a standalone little 5v SPDIF dac block to convert. I have both in my shop but can’t seem to get viable signal to either. All components have been cross tested with other hardware, and the proffie runs fine through the onboard speaker out. We tried the appropriate I2S/SPDIF enable defines in the config (separately, not simultaneous) to no avail. We’re following the V3 pinout diagram from hubbe.net (ie data 3, data 4, free 1 for I2S)… I know the pinouts were different for the V2 boards. One quick question I had (as a non coder so forgive me), when I look at the dac.h file in the Proffie OS 7.0 code, I see reference to the AUX pin being used for data for both I2S and SPDIF, as opposed to Data 3 as on the current pinout diagram. Is it possible I’m using the wrong pins and they switched back to using AUX for some reason without the diagram being updated? If anyone successfully has either digital audio output working on a V3 and could give us insight or share code, we’d be super grateful!
Cheers
