I bought this TFT touch screen today at RadioShack, Seeed 2.8" TFT Display Touch Shield http://www.radioshack.com/product/index.jsp?productId=12688460 I plugged it onto an Arduino Uno and loaded an example sketch from the library' for Arduino 1.0.1. It did not work. So I tried Arduino 1.0.5. It did not work. I downloaded the TFT library off of Adafruit and tried it and used the sample program that SEEEd provides at http://www.seeedstudio.com/wiki/2.8%27%27_TFT_Touch_Shield_V1.0. No matter what I try, I get nothing but a lit up white screen. I dont know if I am missing something here or if this thing just doesnt work.
Go to Seeed's Wiki page @ http://www.seeedstudio.com/wiki/2.8''_TFT_Touch_Shield_V1.0.
Scroll down to Resources where you'll find a link to the libraries for your LCD.
