Arduino to M5Stick

  • For a couple of years I have been using an arduino based morse code decoder that is based on a sketch and some very simple hardware. I don't use it all the time but it has some handy features (like a tuning indicator). I bought an M5Stick and thought it might be quite straightforward to adapt the code to suit the new hardware. It is a bit above my current skill level. I'd still like to use an external audio input with a simple voltage divider and cap rather than the internal mic as it'll give better results.

    I'm looking to get some help on how best to move the code over and particularly the display and scrolling the text etc

    I'll probably have a load of questions as I go through the project but first off is it better to try and put it all into UI Flow first?
