The library will not work with the current verison of the ITDB02 Arduino Shield from ITead or the TFT01 Arduino Shield from ElecFreaks because the shield does not connect the required IRQ signal to the Arduino.

Some demos showcasing most of the functions are included in the download. This is a multi-platform library that will work with several different development board types.
Nice to know:
A program to calibrate the touch screen is included in the download. If your touch screen is inaccurate you simply install and run UTouch_Calibration. Follow the on-screen instruction to calibrate your touch screen.
The supplied calibration parameters are fairly accurate on my 3.2" S module. If you are using any other module you will have to run the calibration. For the best possible results you should run the calibration in any case.
More information about calibration can be found in the included manual. Make sure you read the manual before running the calibration sketch.
