impressive design

you have the code for rpi on github?

Are you sure? yes | no

This one is based on the rp2040 sdk, I just added the code for the TPA6130A2, the volume and screen part is not done yet. Uploaded the audio part of the firmware first, the code is being reorganized.

Are you sure? yes | no
