Soldering pen – a look at the firmware

I’ve spent quite some time trying to figure out whether or not I should post the source code for the soldering pen. It’s not like it’s particular secret or anything but I had a internal battle anyway. In the end I was convinced that it should indeed be open. That also means that you out there can spot errors and help on improving the code.
I don’t see myself as the perfect programmer so you will most likely find some typos and logical errors in there. I know for a fact that I need a watchdog and preferably also some feedback on the input voltage. right now I haven’t done that so USE THIS ON YOUR OWN RISK!
you know how it goes – your own stuff, your own safety. I live in europe so getting sued is not that common but anyway..

without further ado:
