I’ve just received my board, which works fine with Windows XP (though so far I can’t get it working with OSX).
I have a very simple (probably stupid) question. When the board is powered on (e.g. by plugging it into a USB socket on a computer), what script automagically runs? Is it main.py? That seems likely since that produces the blue heartbeat led flashing. If so, I presume rewriting main.py would allow other things to happen on a power-on.
