I use stm32f767 and implement one button in screen

why?

Hello @Community member​ ,

Which display are you using ?

If it is the X-CUBE-DISPLAY, there is no touch sensor implemented in it.

no I use touchscreen FT5316

touch is ok but the interaction not works.

why?

Then the issue comes from the driver of your touchscreen and/or the hardware configuration.

You will have to debug it or find examples/tutorials online.

A good starting point would be to put a breakpoint in your STM32TouchController::sampleTouch(int32_t& x, int32_t& y) method, to see if every time you click, this function is triggered with the right coordinates.

the coordination is accurate equal to button coordinates in touchgfx.

if it trig with worst coordinate why it change the button picture?

Maybe better is show here your interaction code.

Secondsary is box1 visible ?
