Hi everyone,
In my low power application , I use PORT EVENT to detect the interrupts of my two pins. when I use only one pin interrupt, it's working well . But with two interrupts, only one of them are detected.
static void gpiote_port_init() {
NRF_GPIO->PIN_CNF[BOARD_INT1] = (GPIO_PIN_CNF_SENSE_High << GPIO_PIN_CNF_SENSE_Pos)
| (GPIO_PIN_CNF_DRIVE_S0S1 << GPIO_PIN_CNF_DRIVE_Pos)
| (NRF_GPIO_PIN_PULLDOWN<< GPIO_PIN_CNF_PULL_Pos)
| (GPIO_PIN_CNF_INPUT_Connect << GPIO_PIN_CNF_INPUT_Pos)
| (GPIO_PIN_CNF_DIR_Input << GPIO_PIN_CNF_DIR_Pos);
NRF_GPIO->PIN_CNF[BODY_ACCESSORY] = (GPIO_PIN_CNF_SENSE_High << GPIO_PIN_CNF_SENSE_Pos)
| (GPIO_PIN_CNF_DRIVE_S0S1 << GPIO_PIN_CNF_DRIVE_Pos)
| (NRF_GPIO_PIN_PULLUP << GPIO_PIN_CNF_PULL_Pos)
| (GPIO_PIN_CNF_INPUT_Connect << GPIO_PIN_CNF_INPUT_Pos)
| (GPIO_PIN_CNF_DIR_Input << GPIO_PIN_CNF_DIR_Pos);
NRF_GPIOTE->INTENCLR = 0xFFFFFFFF;
NRF_GPIOTE->INTENSET = (GPIOTE_INTENSET_PORT_Set << GPIOTE_INTENSET_PORT_Pos);
NVIC_ClearPendingIRQ(GPIOTE_IRQn);
NVIC_SetPriority(GPIOTE_IRQn, APP_IRQ_PRIORITY_LOW);
NVIC_EnableIRQ(GPIOTE_IRQn);
}
void GPIOTE_IRQHandler(void)
{
// Event causing the interrupt must be cleared
if ((NRF_GPIOTE->EVENTS_PORT != 0))
{
NRF_GPIOTE->EVENTS_PORT = 0;
}
if (nrf_gpio_pin_read(BOARD_INT1) == 1)
{
counter++;
}
if (nrf_gpio_pin_read(BODY_ACCESSORY) == 1)
{
timer_start();
}
}
Is it correct what I did?
