i'm using tis display: http://imall.iteadstudio.com/im120417012.html and an arduino mega. i connected both parts and uploaded the UTFT-demo_320x240 from the henning carlsen UTFT library.
in the code it says
// Uncomment the next line for Arduino Mega
//UTFT myGLCD(ITDB32S,38,39,40,41); // Remember to change the model parameter to suit your display module!
so what about the right nubers there? are the suggested ones right for this display?
the compiling and uploading works fine, but the display only shows a white screen...
Magicj:
How, exactly, have you "connected both parts" ?
I will assume that you are using a shield to connect the parts together, or that you have connected everything correctly...
Now, I suggest that you read the documentation that comes with the UTFT Library - it will explain everything.
HINT - you use ITDB32S in the appropriate line for a 3.2" Screen not the 2.4" screen that you have purchased.
Yes, you are right, i didn't change the model setting. I read the UTFT documentation, but i still don't understand, how i find out the numbers for the pins. Yes, it is a shield, as my posted link says. It also says, that it is 100% mega-compatible, and i am quite sure, that the hadware pinning is correct. but how to find out the right numbers? on my mega board, the pins are called e.g. "A0, A1, D0, D1" and so on, but In the myGLCD(...) there are only digits. so how to find the right numbers relating to my "A1,..." pins?
