ESP8266 Community Forum

I had the same problem,
Just disconnect the MISO from the tft controller, you will then good signal to esp8266 from the touch controller
Problem is that the coordinate system on the touch screen is not the same as the screen coordinates
The X or Y or even both axis are reversed from the touch controller
Try touching at the opposite place on the screen
I placed a patch in the future request section to modify the touch coordinates to match the display coordinates
Hope this helps

x =256 y =65519

x =256 y =65519

x =256 y =65519

x =256 y =65519

x =256 y =65519

x =256 y =65519

You must now be very strong!
I believe, your display is defective.

You do not need the irq line,
As espbasic does not need this line, the touch controller is beeing polled
Normaly if the display is not touched, it reports back y=2047,
X will fluctuate
Can you hook up a scoop to watch the MISO output from the touch controller
This should be a clean 3.3 v pulse train, see if touching changes this pulse train
If not your display may be damaged indeed
