I cant detect touch on STM32f746. I'm using stmpe811 for touch controller

[q123w123e123qweqwe]

Hello,

I'm working on a project an using STM32F746 and STMPE811 for touch controller. I did initializations and everything but no metter hjow much try I can't detect touch. Also I con't do debugging step by step because my code always goes into TIM6_DAC_IRQHandler() funtion. and come back to where it was. it do not go to next line(only if I try debug step by step). So can anyone help me with these issues?

Thank you.

bool STM32TouchController::sampleTouch(int32_t& x, int32_t& y)
{
    if (tsDriver)
    {
        //In here DetectTouch's value is always 0x80060c3 Idk why
        if (tsDriver->DetectTouch(TS_I2C_ADDRESS))
        {
            /* Get each touch coordinates */
            tsDriver->GetXY(TS_I2C_ADDRESS, (uint16_t*)&y, (uint16_t*)&x);
            return true;
        }
    }
    return false;
}

How did you create this project? The code looks like something we wrote for the Touch Controller in the latest application template.

I’ve got it from template project for STM32F429 discovery. Because as I said I’m using stmpe811. So integrated it to stm32f746 custom project. Was it a bad idea?
