I just recently purchased an 2.8"TFT Touch Shield for the Arduino. I am using an Arduino Duemilanove with a 328 inside. I was searching and found this post that was toward the beginning of the forum, as in a long time ago.
I never saw a final solution and I am having the same problem. The white screen you see in the picture on the above forum is what I am seeing. The code compiles correctly and I just don’t know what I am doing wrong. Thanks for your help.
