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
