I am using the HiFiBerry DAC+ DSP platform connected with the Raspberry Pi 4 Model B board.
In my project, I have a I2S microphone connected to the connector P6, namely the digital inputs and outputs 1. I am programming the project with the Analog Device's SigmaStudio.
For the project, I need to transmit and receive signals to/from the RaspBerry Pi. My first question is what are the GPIOs, amonsgt the 40-pin connector, that I can access in order to transmist/receive data? My second question is how can I do this with SigmaStudio?
