external interrupt from gpio

[Mikhail]

SDK13 nRF52 S132.

Hi! Correct I understand and implemented how to make interrupt?

I use gpiote.

void gpiote_init (void) 
{
nrf_gpio_cfg_input(INT1, NRF_GPIO_PIN_NOPULL); //Configure button 0 as input
nrf_gpiote_event_configure(0, INT1, NRF_GPIOTE_POLARITY_TOGGLE); //Configure GPIOTE channel 0, to generate an event from button 0:
NRF_GPIOTE->INTENSET = GPIOTE_INTENSET_IN0_Enabled; //Set GPIOTE interrupt register on channel 0
NVIC_EnableIRQ(GPIOTE_IRQn); //Enable interrupts
}

void GPIOTE_IRQHandler()

{
NRF_GPIOTE->EVENTS_IN[0] = 0;
HAL_GPIO_EXTI_Callback();
}

I don't have ext interrupt.

Hi Mikhail.
Did you remember to initialize the GPIOTE driver?
You can find a lot of information about the GPIOTE here.
Best regards.

Hi! I already decide this problem by use pin_change_int example from SDK\examples\peripheral

Ok, I'm glad you were able to solve your problem.
