Hi there!
Been obsessed since a while into the inner workings of the Arduino Core.
After a while of poking and prodding at it, here is a core template and instructions/tips on how to create your own core!
Plan to add some documentation on how to use it!
Stay tuned.
Based on code from
- ArduinoCore-samd by Arduino
