RE: How to set two interrupts for one pin?

Hi,

The driver does not allow you to configure one pin for multiple actions, this will only result in an error.

If you set PIN_IN to sense TOGGLE, you will get one event when the button is pressed and another event when the button is released. You can use a variable to keep track of the state:

uint8_t button_pressed = 0;

void in_pin_handler(nrf_drv_gpiote_pin_t pin, nrf_gpiote_polarity_t action)
{
    if(button_pressed == 0)
    {
        NRF_LOG_INFO("Button pressed!\r\n");
        button_pressed = 1;
    }
    else
    {
        NRF_LOG_INFO("Button released!\r\n");
        button_pressed = 0;
    }
}

Best regards,

Jørgen
