CoreS3 microphones examples

[jpmartinez]

Hi folks.
Newie here.
My project is to try to build a simple voice tranceiver pairing two S3's using EspNow as a transport layer, only my idea, I've no evidence if should be possible :D.

Exploring UIFlow 2.0 alpha-28 I can't get a direct way to reach the internal mics of the CoreS3. Speaker seems ok because is right there in the UI.

Can I get some examples how to get to work with them the right way?, or even outside UIFlow, I think trought Micropython.

Any help would be greatly appreciated. Thank you so much.
