/*
 *
 * This was originally part of the group documentation, but it was removed,
 * since it's not important for Connect platforms. It is kept as it might become
 * important later when support for new platforms is added.
 *
 * The base time units for events are ticks.  Each tick is approximately equal
 * to a millisecond, but the true duration depends on the platform.  The
 * duration of a tick is 1000 / ::MILLISECOND_TICKS_PER_SECOND, where 1000 is
 * the number of milliseconds per second and ::MILLISECOND_TICKS_PER_SECOND is
 * the platform-specific number of ticks per second.  For example,
 * ::MILLISECOND_TICKS_PER_SECOND on the EM357 SoC is 1024, so each tick is
 * 1000 / 1024 = ~0.98 milliseconds.  Calling
 * ::emberEventControlSetDelayMS(someEvent, 100) on the EM357 SoC will schedule
 * the event for 100 ticks * (1000 milliseconds / 1024 ticks) =
 * ~97.7 milliseconds.  Note, however, that the accuracy of the base tick
 * depends on the timer source.  Furthermore, the scheduled delay is the minimum
 * delay. If ::emberRunEvents or ::emberRunTask are not called frequently
 * enough, the actual delay may be longer than the scheduled delay.
 *
 * Additionally, the APIs for quarter second and minute delays
 * (::emberEventControlSetDelayQS and ::emberEventControlSetDelayMinutes) use
 * "binary" units.  One quarter second is 256 ticks and one minute is 65536
 * ticks.  Calling ::emberEventControlSetDelayMinutes(someEvent, 3) on the
 * EM357 SoC will schedule the event for 3 minutes * (65536 ticks / minute) *
 * (1000 milliseconds / 1024 ticks) = ~3.2 minutes.  It is possible to avoid
 * these binary units by using ::emberEventControlSetDelayMS and the various
 * MILLISECOND_TICKS_PER_XXX multipliers.  For example, calling
 * ::emberEventControlSetDelayMS(someEvent, 3 * MILLISECOND_TICKS_PER_MINUTE)
 * will delay for 3 minutes on any platform.  Be aware of
 * ::EMBER_MAX_EVENT_CONTROL_DELAY_MS when using this approach.

Pointer to the array of events.

An application typically creates an array of events along with their handlers. This function should be called in the main loop to run those events. Warnings

emberRunTask#

void emberRunTask (EmberTaskId taskid)

Start an event handler if there is anything scheduled at the moment this function is called.

Parameters
N/Ataskid

If an application has initialized a task via emberTaskInit(), to run the events associated with that task, it should call emberRunTask() instead of emberRunEvents().

Warnings

  • This is normally handled by the main plugin.

emberMsToNextEvent#

uint32_t emberMsToNextEvent (EmberEventData * events, uint32_t maxMs)

Check when the next event is scheduled to run.

Parameters
[in]events

An array of events to check.

[in]maxMs

If no event is scheduled before maxMs, maxMs will be returned

Returns

  • Returns the number of milliseconds before the next event is scheduled to expire, or maxMs if no event is scheduled to expire within that time.

Note

  • If any events are modified within an interrupt, to guarantee the accuracy of this API, it must be called with interrupts disabled.

emberMsToNextEventExtended#

uint32_t emberMsToNextEventExtended (EmberEventData * events, uint32_t maxMs, uint8_t * returnIndex)

Check when the next event is scheduled to run.

Parameters
[in]events

An array of events to check.

[in]maxMs

If no event is scheduled before maxMs, maxMs will be returned

[out]returnIndex

If not NULL pointer was passed, the index of the next event will be returned here, or 0xFF if no event is scheduled before maxMs.

Returns

  • Returns the number of milliseconds before the next event is scheduled to expire, or maxMs if no event is scheduled to expire within that time.

Note

  • If any events are modified within an interrupt, to guarantee the accuracy of this API, it must be called with interrupts disabled.

emberMsToNextStackEvent#

uint32_t emberMsToNextStackEvent (void )

Check when the next stack event is scheduled to run.

Parameters

Returns

  • Returns the number of milliseconds before the next stack event is scheduled to run.

emberTaskInit#

EmberTaskId emberTaskInit (EmberEventData * events)

Initialize a task for managing events and processor idling state.

Parameters
[in]events

Pointer to the array of events to manage

Returns

  • Returns the EmberTaskId which represents the newly created task.

Note

  • After the task is created emberRunTask() should be called periodically.

emberMarkTaskIdle#

bool emberMarkTaskIdle (EmberTaskId taskid)

Try to idle the CPU, unless any events in any tasks are pending.

Parameters
[in]taskid

the task which should handle the idling.

Returns

  • Returns true if the processor was idled false if idling wasn't permitted because a task has something to do.

Note

  • This API should always be called with interrupts disabled. It will forcibly re-enable interrupts before returning.

emTaskEnableIdling#

void emTaskEnableIdling (bool allow)

Enable or disable idling.

Parameters
[in]allow

Setting it to true will enable, while setting it to false will disable idling.

emMarkTaskActive#

void emMarkTaskActive (EmberTaskId taskid)

Calling it indicates that a task has something to do, so it should prevent the CPU from idling until emberMarkTaskIdle is next called on this task.

Parameters
[in]taskid

The task to mark active.
