Hey M,
Just wanted to thank you for taking the time to post a wonderful tutorial. I found it very useful. I wasn't able to get the sample code to work, but using Thomas Pfeifer's framework and your drawing routines, it work just perfect.
I had trouble using your code in AVR Studio, but Thomas' helped in that respect.
Anyway, just didn't want your efforts to go un-noticed.
Thanks again,
Moe
