This week was embedded programming and the goal was to program our ATtiny44 microcontrolers from the elctronics design week using out fabISP board from the electonics production week. I encountered two problems early on that I hadn't fixed two weeks ago because I didn't have time to program my board.

THe first problem was that I had used a polarized capacitor for my powersource filter because I dropped my other capacitor and only had polarized ones on hand back at my lab. I hadn't been careful however so I put it on backwards and when I tried to program my board this week I burned the capacitor (see panel 1). I fixed this problem useing the soldering tongs in EDS which I have never used before. They were far simpler to use than a reflow gun.

After fixing this I realized that my 6 pin cable had on of its adaptors in the wrong orientation. Making a new cable allowed me to successfully program the board with the echo hello world program! Success I thought... My board must work... For the rest of the HW I decided to use my own laptop to program becuase I was using a computer in EDS and I wanted to make sure I could replicated everything myself

So the first complication is that my laptop only has a thunderbolt port and not a USB port so I had to use an adaptor. First I tried programming my board using Arduino's online dev. This didn't work so I downloaded their software and followed the tutorial of an previously student in the class about how to add ATtiny44 support. I changed the clock to 20MHz but I still counldn't get it to talk with my board. Next I downloaded AVRdude and pyterm and tried to redo everything using these tools but I wasnt even able to detect my board leading me to think that something went wrong between my programming at EDS and my attempts to program at home.
