Hello,

If what is inside your sampleTouch is correct and you receive the correct coordinates according to where you touch, TouchGFX should work just fine.

Please make sure your touch driver is working properly.

Also, please elaborate more. What board are you using ? What version of TouchGFX (should be 4.14) ? What IDE ? etc.

Yes, My touch drivers works fine. and I can touch report point from touch driver interrupt.

MCU: STM32L4R9ZI

TouchGFX: version 4.14

How did you create your project ? What is your display interface (DSI, LTDC, etc.) ?

Also referring to the L4R9-DISCO board Application Template available in TouchGFX Designer could be helpful.
