Just yesterday I was at the Hardware Meetup at C4DI, and I (along with a few other people - thank you for helping :D) was attempting to fix a series of nasty runtime errors. All it gave me was a message in the serial monitor that an exception had occurred, an error code, and a raw stack dump. This wasn't very helpful at all. Even more unhelpful was the lack of help out there on how to decode this information.

I did, however, manage to find a page that contains a list of the different error codes and their meanings. It's not much, but it's a start. It helped us at least to work out what was wrong with it :-)

Arduino Exception Reference

If you're running Windows, then Microsoft have created Visual Micro - a what looks like a perfectly brilliant debugger for the arduino. Apparently you can inspect variables, see the digital pin statuses, and get intellisense lovelyness :D Since I'm running linux, I can't get my hands on it - hopefully someone will build an alternative for linux and other OSes soon!

I also discovered a weird oddity with UDP Multicast in C#. I'm going to investigate further and write up another post that will (hopefully) follow this one.
