Pisound and Circle library

Pisound

Hi, I wonder if someone have experience using Pisound with the bare metal library Circle https://github.com/rsta2/circle

My question is if it is possible to read converted digital data from the I2s port (after Pisound finish a cycle from the ADC), process the sound, and then output the result to the output I2s port connecter to the Pisound DAC converter.
Circle have functionality to control the I2s port for reading and writing but I would like to confirm if that is the only needed requirement (apart of pre configuration of the sample-rate writing in a register) to operate Pisound in a headless OS environment. Thanks

Hey, we haven’t tried it ourselves, but it seems there’s people that did!
