Topic: 2.4 Tft shield touch issue (Read 44 times) previous topic - next topic


Ok so i am a little new at this and I've looked for the better part of 2 days to see if I could find any similar cases but haven't at least as of yet.. so I have a 2.4 mcufriend tft lcd shield running on a UNO board, have loaded the touch calibration sketch and it loads fine, when the prompt shows touch to continue, touch as I might it won't give any feedback, zero ( usb is still plugged into cpu) but... when i unplug it from the usb port and plug in the external power source, calibration works just fine.. plug back into the pc and it's back to no reeponse.  Any light on the subject is appreciated ten fold!
