I thought I’d port my M5Stack Core2 Audio Monitor so that it would work on any ESP32 with a TFT screen - I’m using a TTGO board in this video.
You can find the original video here which goes into more detail on how the code works - there aren’t very many changes from this generic code and M5Core code.
Works pretty well. All you’ll need is a microphone and a dev board with a TFT screen like the TTGO and you’re good to go.
The code is in GitHub - https://github.com/atomic14/esp32-tft-audio-monitor
You should be able to modify it for whatever board you have.
