rp2040-rx

This is a sample project for receiving audio data using RP2040 microcontroller. The chip has a built-in 12-bit ADC which is used to process the analog audio from the external microphone module in real-time.

Setup

Raspberry Pi Pico (or other RP2040 board)
Microphone, tested with the following, but others could be also supported:
- Analog:
  - MAX9814
  - KY-037
  - KY-038
  - WS Sound sensor

Pinout
