ESP32 Audio Monitor
This is a port of this project to work with any ESP32 device with a TFT display.
You can watch a video explainer here (YouTube) which goes into a bit more detail on the audio capabilities of the device.
You'll need to use PlatformIO to build the project.
To clone the repo use:
git clone --recursive git@github.com:atomic14/m5stack-core2-audio-monitor.git
This will make sure you get the TFT library as well.
Hopefully, the code should be easy to understand.
If you want to add some more visualisations then please open up a pull request and contribute some code.
To modify the code to work with your particular device you will need to change the settings in platformio.ini to match your TFT. The easiest way to do this is to look in the lib/TFT_eSPI/User_Setups for your device and copy the required pre-processor defines.
If you are feeling lazy then you can just copy the setup for you TFT over the User_Setup.h and remove the defines from the build settings.
If you take the lazy option, then remember to remove -DUSER_SETUP_LOADED=1.
