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?

[Turbo J]

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,

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;

Hi, Can you help with the same problem

I am enabling a interrupt using this code

        nrf_drv_gpiote_in_config_t gpiote_inConfig =
        {
            .sense           = senseTrnsiton,                         \
            .pull            = GPIO_PIN_CNF_PULL_Pullup,              \
            .is_watcher      = false,                                 \
            .hi_accuracy     = true,                                  \
            .skip_gpio_setup = false,                                 \
        };
        err_code = nrf_drv_gpiote_in_init(pin_number, &gpiote_inConfig, gpiote_drvInEventhandler);
        *gpiote_appInEventHandler[pin_number] = actionEvent;
        APP_ERROR_CHECK(err_code);
        nrf_drv_gpiote_in_event_enable(pin_number, true);

and want to disable this event inside the event handler as soon as it triggers.

I am calling this function to disable interrupt.

nrf_drv_gpiote_in_event_disable(pin_number);

But its not working. Please help.

Hi 

Did you figure this out? 

It is not recommended to re-open old cases like this, it is better to open a new devzone ticket.

I have been on vacation for the last couple of weeks, and didn't notice it. 

Best regards
