Dear all
The ISR of a gpio interrupt triggers only once. I cleared the interrupt flag in the ISR and the interrupts are not disabled anywhere in the code. Does anyone how I can solve that issue? (I am using MQX 4.2 and the Vybrid VF61 Cortex M4)
Interrupt initialisation:
void gpio_init(void)
{
static LWGPIO_STRUCT temp_gpio;
lwgpio_init(&temp_gpio, LWGPIO_PTE14, LWGPIO_DIR_INPUT, LWGPIO_VALUE_NOCHANGE);
lwgpio_set_functionality(&temp_gpio, 1); /*sets the gpio mux to gpio setting*/
lwgpio_set_attribute(&temp_gpio, LWGPIO_ATTR_OPEN_DRAIN, LWGPIO_AVAL_ENABLE);
lwgpio_int_init(&temp_gpio, LWGPIO_INT_MODE_FALLING );
_int_install_isr(lwgpio_int_get_vector(&temp_gpio), portE_int_handler , (void *)&temp_gpio);
_bsp_int_init(lwgpio_int_get_vector(&temp_gpio), 3, 0, TRUE); /*initialize the interrupt and set its priority. */
lwgpio_int_enable(&temp_gpio, TRUE); /*enable the interrupt for use*/
}
ISR:
static void portE_int_handler(void *pin)
{
printf("interrupt happened\n");
lwgpio_int_clear_flag((LWGPIO_STRUCT_PTR) pin);
}
