app_sched_event_put from GPIOTE_IRQHandler

[aep]

Hi, i'm trying to read an i2c sensor on interrupt. Doing it directly in the interrupt is apparantly bad, so io tried using app_sched_event_put, but that just crashes inside propriatary code.

How do i run stuff from interrupts then?

     if (NRF_GPIOTE->EVENTS_PORT) {
          NRF_GPIOTE->EVENTS_PORT = 0;
           app_sched_event_put(NULL, 0, sensor_event_handler);
          }
      }
 }

Is the SD initialized?

Do you set the interrupt priority to either APP_PRIORITY_HIGH or APP_PRIORITY_LOW?

Hi Ole,

Do you have any solutions on it?

I also caught this issue when I try the scheduler put in the interrupt function of lpcomp, whose LPCOMP_CONFIG_IRQ_PRIORITY level is 6.  And the platform is 15.2, which defines CRITICAL_REGION_ENTER as:

#ifdef SOFTDEVICE_PRESENT
#define CRITICAL_REGION_ENTER() \
{ \
uint8_t __CR_NESTED = 0; \
app_util_critical_region_enter(&__CR_NESTED);
#else
#define CRITICAL_REGION_ENTER() app_util_critical_region_enter(NULL)
#endif

void app_util_critical_region_enter(uint8_t *p_nested)
{
#if __CORTEX_M == (0x04U)
ASSERT(APP_LEVEL_PRIVILEGED == privilege_level_get())
#endif

#if defined(SOFTDEVICE_PRESENT)
/* return value can be safely ignored */
(void) sd_nvic_critical_region_enter(p_nested);
#else
app_util_disable_irq();
#endif
}
