Lets get the screen working and go from there.
First off, you need to go to file - examples - ITDB02_Touch - Touch calibration.
Go through the steps, and it will give you 4 numbers. Write these numbers down, you'll need them for the next step
Next, go to libraries - ITDB02_Touch Folder, open it and go to ITDB02_Touch.cpp
You want to edit this file. Open the file and look for this line:
#define PixSizeX -15.38
#define PixOffsX 213
#define PixSizeY 11.15
#define PixOffsY 311
Enter the 4 numbers that you got from your touch screen calibration here, then save the file.
Next, open the Jarduinio sketch, make sure this one line looks like below:
//TOUCH PANEL and ITDB02 MEGA SHIELD
//(Mega Shield utilizes pins 5V, 3V3, GND, 2-6, 20-41, & (50-53 for SD Card))
ITDB02 myGLCD(38,39,40,41); //May need to add "ITDB32S" depending on LCD controller
Once you do this it should compile and be able to upload.
