With my Feather M4 Express I want to read/write an integer number (1 to 10) to (non volatile) memory on the board.
As a beginner and being in a Circuit(Python) learning process, I am struggling with this problem.
Do I have to use a "Bytearray"? Or can I make a small textfile in memory (in the CIRCUITPY directory?), where I can read and write this number?
It's hard to find any simple example....
