Hi Oliver,
I'm mainly using Adafruit library however I have tried the Arduino library and some programs written by other people.
I've tried connecting it every way possible according the sketch I load.
I have managed to get the screen to coincide brightness with the sketches and this was achieved by removing the VCC line. It will go black when the sketch resets and then the alternating brightness starts again. I just downloaded the UTFT library by Henning Karlsen, I'll try some of these sketches.
I have tried 3.3 volts to the backlight and that did nothing.
I upgraded my Arduino IDE to 1.0.5-r2 and now I'm getting crazy errors when I try and compile the Adafruit sketches...it's looking for files in the Robot directories , I still have my original copy of the IDE so at least I'm safe there.
It's very frustrating that this TFT screen is a key aspect of my little project and it looks like at this point it was just a waste of time. I'm talking 3 days trying to get the screen to work.
I've read every post in the universe about these things I've gone over the data sheet for hours thinking maybe something will ....I don't know. As far as the data sheet even goes....99.99999% is far beyond me.
I did get the SD card reader to work...I think. It sees the card but it's not formatted correctly because it from an old camera but it did see a card so I assume it was working, although I don't really need the SD reader for my soon to be done city, outta here project
EDIT: I just looked at the UTFT examples...I don't even know what those are.
