API#

void
sl_zigbee_af_isr_event_init(sl_zigbee_event_t *event, void(*handler)(sl_zigbee_event_t *))

Application event initialization routine for events intended to be activated in ISR. An event that is activated in ISR context must be initialized using this API. Such event can only be scheduled to expire immediately using sl_zigbee_event_set_active. The event handler will be executed from DSR context either from the application main loop in a bare metal setup or in the Application Framework Task main loop in an OS setup. Any attempt to schedule a non zero delay or deactivation for an event initialized as ISR event will result in an assert.

void
sl_zigbee_event_init(sl_zigbee_event_t *event, void(*handler)(sl_zigbee_event_t *))

Application event initialization routine. Every application event must be initialized.

void
sl_zigbee_event_set_delay_ms(sl_zigbee_event_t *event, uint32_t delay)

Schedule an event to run after a delay expressed in milliseconds.

void
sl_zigbee_event_set_active(sl_zigbee_event_t *event)

Schedule an event to run immediately.

void
sl_zigbee_event_set_inactive(sl_zigbee_event_t *event)

Cancel an event.

bool
sl_zigbee_event_is_scheduled(sl_zigbee_event_t *event)

Returns true if the event is scheduled to run, false otherwise.

uint32_t
sl_zigbee_event_get_remaining_ms(sl_zigbee_event_t *event)

Returns the number of milliseconds before the event runs, or -1 if the event is not scheduled to run.

sl_zigbee_af_isr_event_init#

void sl_zigbee_af_isr_event_init (sl_zigbee_event_t * event, void(*)(sl_zigbee_event_t *) handler)

Application event initialization routine for events intended to be activated in ISR. An event that is activated in ISR context must be initialized using this API. Such event can only be scheduled to expire immediately using sl_zigbee_event_set_active. The event handler will be executed from DSR context either from the application main loop in a bare metal setup or in the Application Framework Task main loop in an OS setup. Any attempt to schedule a non zero delay or deactivation for an event initialized as ISR event will result in an assert.
