About AM437x ADC0 FOUR_WIRE HW Interrupt configuration

Hi Aria,

What software are you using?

hi

everyone

AM335X_StarterWare_02_00_01_01 → touchScreen

StarterWare_02_01_00_02 → ADC0

void TSCADCStepEnable(uint32_t baseAddr, uint32_t stepNum, uint32_t enableStep)
{
    uint32_t regVal = HW_RD_REG32(baseAddr + ADC0_STEPEN);

    if (TRUE == enableStep)
    {
        regVal |= (1 << stepNum);
    }
    else
    {
        regVal &= ~(1 << stepNum);
    }

    HW_WR_REG32((baseAddr + ADC0_STEPEN), regVal);
}

            for(i = 0; i < 11; i++)
            {
            	TSCADCStepEnable(pCfgAdc->instAddr, i, TRUE);
            }


      

I want to use the above function enable10 a step but stepen（offset=54h） registers are shown 0x01 all the time

regards,

aria li

I will move this to the Starterware forum.

hi

I did a further inspection, when i clicked the "ADCSTAT - PENIRQ0" value is "1" ,but   interrupt not trigger . other ADC0 register values the same as 335 x registers, I have enabled the “TSCADCIntrEnable (pCfgAdc - > instAddr, TSCADC_INTR_MASK_FIFO1_THRESHOLD)”.

Hi aria li,

The StarterWare 02.01.00.02 does not have an example application for the resistive touchscreen. A cap_tsc example application is provided for the Capacitive Touchscreen attached on the AM43x GPEVM board.

If you are trying to configure resistive touchscreen on the AM437x GPEVM board then these configurations will not work.

hi Anant

  Thanks for your advice,

  clould you tell me how to configure the resistive screen register?

thaks
