Hello. the touch works but if I want turn on the led by clicking the button, sometime at the first try the led turns on and sometimes I have to try multiple time(As I show it at the video I uploaded). When I fixed the touch point manually inside the code and press the button it works perfectly for that specific point. The problem is when I touch the screen the read point vary slightly. The color of button change(it show that the press screen is sensed) but the corresponding function work randomly.
for propagate the touch event I used below code:
bool STM32TouchController::sampleTouch(int32_t& x, int32_t& y)
{
if(XPT2046_TouchPressed())
{
XPT2046_TouchGetCoordinates((uint16_t*) &x, (uint16_t*) &y);
return true;
}
/**
* By default sampleTouch returns false,
* return true if a touch has been detected, otherwise false.
*
* Coordinates are passed to the caller by reference by x and y.
*
* This function is called by the TouchGFX framework.
* By default sampleTouch is called every tick, this can be adjusted by HAL::setTouchSampleRate(int8_t);
*
*/
return false;
}
