I am having an issue with pin changes triggering interrupts using app_gpiote. I've set up app_gpiote to watch pin 30 and trigger an interrupt on low-to-high or high-to-low. I've followed the example code closely, but the pin change (up or down) does not cause the interrupt handler to start. I am certain the pin change is occurring because I am monitoring it with a logic analyzer. Here is my code.
static void event_handler_int(uint32_t event_pins_low_to_high, uint32_t event_pins_high_to_low)
{nrf_gpio_pin_toggle(LED_0);}
static bool gpiote_init(void)
{
uint32_t retval;
nrf_gpio_cfg_output(LED_0);
nrf_gpio_cfg_output(LED_1);
APP_GPIOTE_INIT(APP_GPIOTE_MAX_USERS);
retval = app_gpiote_user_register(&my_user_id,
1 << 30,
1 << 30,
event_handler_int);
if(retval != NRF_SUCCESS)
{
return false;
}
retval = app_gpiote_user_enable(my_user_id);
if(retval != NRF_SUCCESS)
{
return false;
}
return true;
}
The gpiote_init function returns true, so it seems that the various initialization calls to app_gpiote are functioning properly. Any idea what is going on here?
P.S. Apologies for the messed up code formatting, can't seem to figure out the issue with it...
