Project instructions
- - read an AVR data sheet
- - make serial and programming cables
- - add (at least) a button to the serial echo hello-world board
- - modify the serial echo assembly program to respond to the button
- - modify the serial echo C program to respond to the board
What I learned wile doing the project
- First mistake I made was based on my knowlage of the modela machine ,what I did was.. I drew the circuit board in inkskape and exported to png file. The thing that I did wrong was to take try printing it directly like I'm use to with cad file. First you need to write the actual size of the board in inches in the Cad program. That is the diffrence between taking A cad file into Cad program and taking A png file.
- The second one I did was that I soldered the "at tiny 44" the oppisite way.
- Wile I made my programming cables I connected one of them wrong and it dident work so I made a new one and it worked.
