I have an arduino mega and 3.2 TFT touch screen LCD shield and I have uploaded the UTFT_buttons and Utouch programs and I can't get them to work properly when I try and press the buttons. The calibration program that I have tried from that UTouch doesn't work after I follow the instructions and change the numbers in the UTouchCD file. Anyone have any idea of what is wrong? I read that changing the HW_AVR.inc and adding a delay could help but I can't open the file on my Mac. Please, if anyone could help I will really appreciate it.
I did what some other users suggested in other posts and changed the HW_ARM.inc file but I don't understand why it says text file now when I open it. If anyone has the file with the delay that actually works can you please email or post a link to it.
