I'm using this TFT display touch shield with a Arduino Leonardo board
http://dx.com/p/2-8-tft-lcd-touch-shield-module-for-arduino-silver-blue-black-223437#.Uvt78ie0ewI
with the UTFT and UTouch libraries.
The example UTouch_ButtonTest works apart from the position detected seem completely off. The buttons are not correctly detected. Therefore I have tried the UToch_Calibration example. After updating the UtouchCD.h file according to given values things seem even more wrong. I only get x,y values of 0,0 or -1,-1 no matter were I touch the screen.
The new calibration values I got was
CAL_X 03D780A2UL
CAL_Y 03DC80A4UL
CAL_S 0000000UL
