How to mask pin change inerrupt?

[pd@learner]

I am new to nrf52832. I am using pin change interrupt. I want to know that how to mask  pin change interrupt?

Thanks in Advance

nrf_drv_gpiote_in_event_disable which in turn calls nrfx_gpiote_in_event_disable seems to be disabling the interrupt in nrfx_gpiote.c (SDK15.2)

sorry for late reply. I am using sdk12.3.0 and pca10040 board. I have already tried with  nrf_drv_gpiote_in_event_disable but interrupt is not disabled.

Hey,

Here is what the documentation of the in_event_enable function says.

/**
 * @brief Function for enabling sensing of a GPIOTE input pin.
 *
 * @details If the input pin is configured as high-accuracy pin, the function
 * enables an IN_EVENT. Otherwise, the function enables the GPIO sense mechanism.
 * Note that a PORT event is shared between multiple pins, therefore the
 * interrupt is always enabled.
 *
 * @param[in] pin       Pin.
 * @param[in] int_enable  True to enable the interrupt. Always valid for a high-accuracy pin.
 */

Note that a PORT event is shared between multiple pins, therefore the interrupt is always enabled.

@param[in] int_enable  True to enable the interrupt. Always valid for a high-accuracy pin.

Maybe you can try using uninit before going to sleep and init it back again when the device wakes up.

void nrf_drv_gpiote_in_uninit(nrf_drv_gpiote_pin_t pin);

thanks for quick response. i will check it using void nrf_drv_gpiote_in_uninit(nrf_drv_gpiote_pin_t pin)
