I2S and USB Audio

[yuri-evangelista]

Hi, wonderful work here! Thank you very much.

I have a question but not sure if anyone can help right now (maybe it will be solved by the next TinyUSB version).

I'm struggling with the problem of developing a USB microphone using a Pi Pico and 2 MEMS I2S mics.
At present I can:

• have the board recognized as an USB audio device (but not I2S) using the mbed core and this library https://github.com/tierneytim/Pico-USB-audio
• have the I2S working (but no USB audio device) using the arduino-pico core
  Is there a way to "merge" things in order to obtain a working USB microphone based on I2S mics?
  Thank you very much!
  Yuri

You might look at Phil Schatzmann's fork of the Adafruit TinyUSB code. He has USB Audio working with Arduino-Pico.
