Disabling the GPIOTE interrupt using INTENCLR

[Indhu N]

Hi, I am using nrf52832 board. I was trying to disable the GPIOTE interrupt for a particular event (Event4) using INTENCLR register.  My code was NRF_GPIOTE->INTENCLR = 1 < < 4; But still the interrupt is not getting disabled. How to do the disabling actually?

NRF_GPIOTE->INTENCLR = NRF_GPIOTE_INT_IN4_MASK;

That should disable the interrupt for IN[4] event.

Not sure what your code does, there seems to be  white space between the "<". Should yield a compiler error IMHO.

Hi Turbo J, 

There is no white space between "<" and I don't get any compiler error.

Hi,

Can we have a telephonic discussion regarding this issue?

Thanks

Hi 

Could you describe the issue in a bit more detail?

Could there be any other GPIOTE events that trigger the interrupt, or are you sure it is the IN[4] event that is the cause?

Are you able to share your code so I can have a look at it?

Best regards

Hi,

Here is the section of code in which I am trying to disable the GPIOTE interrupts. This product communicates to Mobile device using BLE. Can you please go through this and suggest a solution?

#define LOGIC_HIGH                                    1

#define LOGIC_LOW                                     0

enum interrupt_events_t {

    EVENT0 = 0,

    EVENT1,                                        

    EVENT2,                                        

    EVENT3,                                        

    EVENT4,                                        

    EVENT5,                                        

    EVENT6,                                        

    EVENT7                                        

};

void enableTrashBinInterrupt() {

    NRF_GPIOTE->INTENSET = LOGIC_HIGH << EVENT5;

}

void enableTrayLidInterrupt() {

    NRF_GPIOTE->INTENSET = LOGIC_HIGH << EVENT4;

}

void disableTrashBinInterrupt() {

    NRF_GPIOTE->INTENCLR = LOGIC_HIGH << EVENT5;

}

void disableTrayLidInterrupt() {

    NRF_GPIOTE->INTENCLR = LOGIC_HIGH << EVENT4;

} 

int main(void) {

   

    /* Switches, LEDs, ADC initialisations*/

    

    if (deviceStatus == TEST_PASSED) {               

        lockTrayLidAndTrashBin();

        goToHomePosition();                          

        enableTrashBinInterrupt();

        enableTrayLidInterrupt();

        if (deviceCalibrationStatus == DEVICE_CALIBRATED)                 

            disposeTip();                                                

        if (currentState != ERROR_STATE)                             

            goToLoadingPosition();                                        

    }

    unlockTrayLidAndTrashBin();

    runConfirmationBuzzer();                                              

    nrf_delay_ms(100);  

    disableTrashBinInterrupt();

    disableTrayLidInterrupt();

    err_code = advertisementInit(false);                                  // Initialize the bluetooth communication

    bootupErrorHandler(err_code);                                         

    

    if (err_code == NRF_SUCCESS) {

        err_code = startAdvertisement();                                  

        bootupErrorHandler(err_code);

    } 

   

    while(1) {

    // waiting for start command from apk

    }

}

Thanks

Hi

What does your interrupt handler look like?

Could you try to clear the event in the disable interrupt functions, in addition to writing to the INTENCLR register?

Like so:

NRF_GPIOTE->INTENCLR = LOGIC_HIGH << EVENT5;
NRF_GPIOTE->EVENTS_IN[5] = 0;
