Disabling the GPIOTE interrupt using INTENCLR

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.

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.

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,

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

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
Torbjørn

Hi,

Can we have a telephonic discussion regarding this issue?

Thanks

Hi Turbo J,

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

Turbo J — Mon, 10 Sep 2018 09:52:24 GMT

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.
