I've been struggling with I2S these days.
Currently, I have an ADC which only works in master mode. It has an oscillator itself, and is incompatible with Pi's clock.
Maybe putting raspberry pi's I2S into slave mode will work.
The datasheet says that modifying the BCKO and LRKO registers can achieve this, but how? Build a driver myself?
I'm not pretty well at programming, but doing some small hacks is fine.
Does anyone have an idea?
PS: I followed the steps at https://learn.adafruit.com/adafruit-i2s ... g-and-test , and I am able to use my DAC. However, my ADC just won't work.
