NRF522832 GPIOTE interrupt Interrupt configuration and current

[chanlove1987]

Hi,everyone!

I  need to configure an external interrupt so that when the interrupt is triggered, I can do something else

void tap_int_handler(nrf_drv_gpiote_pin_t pin, nrf_gpiote_polarity_t action)
{

    read_tap_state();
	
}

When I configure it in the following code, it does not break, but its current is normal, only 3uA

    nrf_drv_gpiote_in_config_t in_config = GPIOTE_CONFIG_IN_SENSE_LOTOHI(false);
    in_config.pull = NRF_GPIO_PIN_PULLDOWN;

    err_code = nrf_drv_gpiote_in_init(TAP_INT, &in_config, tap_int_handler);
    APP_ERROR_CHECK(err_code);  
    nrf_drv_gpiote_in_event_enable(TAP_INT, true);

When I configure it with the following code, it will break, but the current is 10uA,

    nrf_drv_gpiote_in_config_t in_config = GPIOTE_CONFIG_IN_SENSE_LOTOHI(true);
    in_config.pull = NRF_GPIO_PIN_PULLDOWN;

    err_code = nrf_drv_gpiote_in_init(TAP_INT, &in_config, tap_int_handler);
    APP_ERROR_CHECK(err_code);  
    nrf_drv_gpiote_in_event_enable(TAP_INT, true);

How can I make it both interruptible and as little current as possible

thanks!

Did you remember to configure the GPIO where the interrupt is triggered?

nrf_gpio_cfg_input() can be used to configure a GPIO as input.
