Hi

Im looking to write firmware for the XMOS chip on the ReSpeaker Lite Voice Assistant Kit
However im not sure what pins are being used to connect the ESP32 to the XMOS XU316.

Please can someone clarity the pins that are connected on both chips? The ESP32 is using
GPIO8 - bclk,
GPIO7 - ws/lrck,
GPIO43 - dout,
GPIO44 - din

But what pins on the XMOS are being used to recieve these signals?

Is there a schematic available for this Kit, or a link to the source code that was modified from the original found here?

Kind regards
