M5Stack Core 2 Audio
You can watch a video explainer here (YouTube) which goes into a bit more detail on the audio capabilities of the device.
This project is a nice little demo of audio on the M5Stack Core 2 with some simple visualisations.
You'll need to use PlatformIO to build the project.
To clone the repo use:
git clone --recursive [email protected]:atomic14/m5stack-core2-audio-monitor.git
This will make sure you get the M5Core2 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.
And if you'd like to buy me a coffee...
