Hello! In project i am get in interrupt touch coordinate and handled in STM32TouchController::sampleTouch:
bool STM32TouchController::sampleTouch(int32_t& x, int32_t& y)
{
/**
* 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);
*
*/
if (ft_initialized)
{
if (ft5206.touchDetected)
{
x = ft5206.touchCoordinatesX[0];
y = ft5206.touchCoordinatesY[0];
ft5206.touchDetected = 0;
return true;
}
}
return false;
}
But function Screen1ViewBase::buttonCallbackHandler never call:
void TestViewBase::buttonCallbackHandler(const touchgfx::AbstractButton& src)
{
if (&src == &button1)
{
//Interaction1
//When button1 clicked change color of box1
//Set RGB color R:255, G:0, B:0 on box1
box1.setColor(touchgfx::Color::getColorFrom24BitRGB(255,0,0));
box1.invalidate();
}
}
TestViewBase::TestViewBase() :
buttonCallback(this, &TestViewBase::buttonCallbackHandler)
{
box1.setPosition(0, 0, 800, 480);
box1.setColor(touchgfx::Color::getColorFrom24BitRGB(63, 59, 107));
button1.setXY(315, 210);
button1.setBitmaps(touchgfx::Bitmap(BITMAP_BLUE_BUTTONS_ROUND_EDGE_SMALL_ID), touchgfx::Bitmap(BITMAP_BLUE_BUTTONS_ROUND_EDGE_SMALL_PRESSED_ID));
button1.setAction(buttonCallback);
add(box1);
add(button1);
}
