I've got the same kit ... I can't get my start with it. I did do http://henningkarlsen.com
UTFT to prove the screen. It was a sine wave and all but sometimes quite noisy. With that great reference for the functions, so I'm not too worried about getting what I want to show up on the screen.
But as time passes, the display gets more and more scattered so when I try the Touch demos, I'm not able to really see anything.
I feel like I'm missing something simple to get going... any ideas on simple sketches that got you started?
