dwm_gpio_irq_cfg

Configures interrupts for GPIO pin. The maximum number of interrupts that can be registered for GPIO pins is 8. Users should only register up to 3 interrupts since DWM already uses 5 GPIO pins for internal purposes.

void dwm_gpio_irq_cfg(uint8_t gpio_idx, uint8_t irq_type, void (*callback)(void*), void *user_data);

Parameters

• irq_type – : ‘1’ | ’2’ | ’3’ (interrupt type, 1=rising, 2=falling, 3=both)

• callback – : (interrupt callback)

• user_data – : (data that user wants to modify in the callback)

• output – Status code

C code example

void gpio_cb(void* p_data)
{
     /* callback routine */
}
…
dwm_gpio_irq_cfg(DWM_GPIO_IDX_13, DWM_IRQ_TYPE_EDGE_RISING, &gpio_cb, NULL);
