Making a RP2040 USB sound Card

Hardware Nano Family Nano RP2040 Connect

Hi all,

I'm developing a USB sound card with the RP2040. I've made a 4th order software sigma-delta modulator with 32 times oversampling. This allows the RP2040 to natively output audio when connected to a laptop/computer over USB.

I'd appreciate any feedback on my github if you think this is interesting.

Thanks
