Closed kholia closed 3 weeks ago

It would be awesome to add support for Raspberry Pi Pico 2.

Pico 2 has fixed the ADC bug which is relevant for https://github.com/batica81/microphone-library-for-pico work.

Thanks!

Hi @kholia,

Have you tried the library as is on the RPi Pico 2?

This library works fine as is! Thanks for the pointer.
