Progress!

01-31-08: We've mostly figured out the A2D. ADMUX is used to pick the input channel for the mux (we're not sure what physical pins the channels correspond to yet). ADC stores the converted data. We also got the LCD to display text.

Next time: use BitScope to find which pin we're reading.

More ADC code, discussion

ADC sample code

Here is the site where some ADC code can be found. It's inside the 0.7.2 zip file as ADC.c.

I put the AVR Studio installer (aStudio4b528.exe) on the Memorex flash drive. It's 73Mb and you have to register on their site to download it, so you can use that if you want to save a step.
