- * and a pointer to back to the object that contains it. These later two

- *
- * A queue set must be explicitly created using a call to xQueueCreateSet()

- *
- * Note 1: See the documentation on http://wwwFreeRTOS.org/RTOS-queue-sets.html
- * for reasons why queue sets are very rarely needed in practice as there are
- * simpler methods of blocking on multiple objects.
- *
- * Note 2: Blocking on a queue set that contains a mutex will not cause the
- * mutex holder to inherit the priority of the blocked task.
- *
- * Note 3: An additional 4 bytes of RAM is required for each space in a every
- * queue added to a queue set. Therefore counting semaphores that have a high
- * maximum count value should not be added to a queue set.
- *
- * Note 4: A receive (in the case of a queue) or take (in the case of a
- * semaphore) operation must not be performed on a member of a queue set unless
- * a call to xQueueSelectFromSet() has first returned a handle to that set member.
- *
- * @param uxEventQueueLength Queue sets store events that occur on
- * the queues and semaphores contained in the set. uxEventQueueLength specifies
- * the maximum number of events that can be queued at once. To be absolutely
- * certain that events are not lost uxEventQueueLength should be set to the
- * total sum of the length of the queues added to the set, where binary
- * semaphores and mutexes have a length of 1, and counting semaphores have a

- * + If a queue set is to hold a counting semaphore that has a maximum count of
- * 5, and a counting semaphore that has a maximum count of 3, then

- * semphr. h
- * vSemaphoreCreateBinary( xSemaphoreHandle xSemaphore )
- *
- * Macro that implements a semaphore by using the existing queue mechanism.
- * The queue length is 1 as this is a binary semaphore. The data size is 0
- * as we don't want to actually store any data - we just want to know if the
- * queue is empty or full.
- *
- * This type of semaphore can be used for pure synchronisation between tasks or
- * between an interrupt and a task. The semaphore need not be given back once
- * obtained, so one task/interrupt can continuously 'give' the semaphore while
- * another continuously 'takes' the semaphore. For this reason this type of
- * semaphore does not use a priority inheritance mechanism. For an alternative
- * that does use priority inheritance see xSemaphoreCreateMutex().
- *
- * @param xSemaphore Handle to the created semaphore. Should be of type xSemaphoreHandle.
- *
- * Example usage:
-
- xSemaphoreHandle xSemaphore;
-
- void vATask( void * pvParameters )
- {
- // Semaphore cannot be used before a call to vSemaphoreCreateBinary ().
- // This is a macro so pass the variable in directly.
- vSemaphoreCreateBinary( xSemaphore );
-
- if( xSemaphore != NULL )
- {
- // The semaphore was created successfully.
- // The semaphore can now be used.

- *
- * Macro that creates a counting semaphore by using the existing
- * queue mechanism.
- *
- * Counting semaphores are typically used for two things:
- *
- * 1) Counting events.
- *
- * In this usage scenario an event handler will 'give' a semaphore each time
- * an event occurs (incrementing the semaphore count value), and a handler
- * task will 'take' a semaphore each time it processes an event
- * (decrementing the semaphore count value). The count value is therefore
- * the difference between the number of events that have occurred and the
- * number that have been processed. In this case it is desirable for the
- * initial count value to be zero.
- *
- * 2) Resource management.
- *
- * In this usage scenario the count value indicates the number of resources
- * available. To obtain control of a resource a task must first obtain a
- * semaphore - decrementing the semaphore count value. When the count value
- * reaches zero there are no free resources. When a task finishes with the
- * resource it 'gives' the semaphore back - incrementing the semaphore count
- * value. In this case it is desirable for the initial count value to be
- * equal to the maximum count value, indicating that all resources are free.
- *
- * @param uxMaxCount The maximum count value that can be reached. When the
- * semaphore reaches this value it can no longer be 'given'.
- *
- * @param uxInitialCount The count value assigned to the semaphore when it is
- * created.

- * portTickType xTimerPeriodInTicks,
- * unsigned portBASE_TYPE uxAutoReload,
- * void * pvTimerID,
- * tmrTIMER_CALLBACK pxCallbackFunction );
- *
- * Creates a new software timer instance. This allocates the storage required
- * by the new timer, initialises the new timers internal state, and returns a
- * handle by which the new timer can be referenced.
- *
- * Timers are created in the dormant state. The xTimerStart(), xTimerReset(),
- * xTimerStartFromISR(), xTimerResetFromISR(), xTimerChangePeriod() and
- * xTimerChangePeriodFromISR() API functions can all be used to transition a timer into the
- * active state.
- *
- * @param pcTimerName A text name that is assigned to the timer. This is done
- * purely to assist debugging. The kernel itself only ever references a timer by
- * its handle, and never by its name.
- *
- * @param xTimerPeriodInTicks The timer period. The time is defined in tick periods so
- * the constant portTICK_RATE_MS can be used to convert a time that has been
- * specified in milliseconds. For example, if the timer must expire after 100
- * ticks, then xTimerPeriodInTicks should be set to 100. Alternatively, if the timer
- * must expire after 500ms, then xPeriod can be set to ( 500 / portTICK_RATE_MS )
- * provided configTICK_RATE_HZ is less than or equal to 1000.
- *
- * @param uxAutoReload If uxAutoReload is set to pdTRUE then the timer will
- * expire repeatedly with a frequency set by the xTimerPeriodInTicks parameter. If
- * uxAutoReload is set to pdFALSE then the timer will be a one-shot timer and
- * enter the dormant state after it expires.
- *
- * @param pvTimerID An identifier that is assigned to the timer being created.
- * Typically this would be used in the timer callback function to identify which
- * timer expired when the same callback function is assigned to more than one
- * timer.
- *
- * @param pxCallbackFunction The function to call when the timer expires.
- * Callback functions must have the prototype defined by tmrTIMER_CALLBACK,
- * which is "void vCallbackFunction( xTimerHandle xTimer );".
- *
- * @return If the timer is successfully create then a handle to the newly
- * created timer is returned. If the timer cannot be created (because either
- * there is insufficient FreeRTOS heap remaining to allocate the timer
- * structures, or the timer period was set to 0) then 0 is returned.
- *

- * portBASE_TYPE xTimerResetFromISR( xTimerHandle xTimer,
- * portBASE_TYPE *pxHigherPriorityTaskWoken );
- *
- * A version of xTimerReset() that can be called from an interrupt service
- * routine.
- *
- * @param xTimer The handle of the timer that is to be started, reset, or
- * restarted.
- *
- * @param pxHigherPriorityTaskWoken The timer service/daemon task spends most
- * of its time in the Blocked state, waiting for messages to arrive on the timer
- * command queue. Calling xTimerResetFromISR() writes a message to the timer
- * command queue, so has the potential to transition the timer service/daemon
- * task out of the Blocked state. If calling xTimerResetFromISR() causes the
- * timer service/daemon task to leave the Blocked state, and the timer service/
- * daemon task has a priority equal to or greater than the currently executing
- * task (the task that was interrupted), then *pxHigherPriorityTaskWoken will
- * get set to pdTRUE internally within the xTimerResetFromISR() function. If
- * xTimerResetFromISR() sets this value to pdTRUE then a context switch should
- * be performed before the interrupt exits.
- *
- * @return pdFAIL will be returned if the reset command could not be sent to
- * the timer command queue. pdPASS will be returned if the command was
- * successfully sent to the timer command queue. When the command is actually
- * processed will depend on the priority of the timer service/daemon task
- * relative to other tasks in the system, although the timers expiry time is
- * relative to when xTimerResetFromISR() is actually called. The timer service/daemon
- * task priority is set by the configTIMER_TASK_PRIORITY configuration constant.
- *
- * Example usage:
- *
- * // This scenario assumes xBacklightTimer has already been created. When a
- * // key is pressed, an LCD back-light is switched on. If 5 seconds pass
- * // without a key being pressed, then the LCD back-light is switched off. In
- * // this case, the timer is a one-shot timer, and unlike the example given for
- * // the xTimerReset() function, the key press event handler is an interrupt
- * // service routine.
- *
- * // The callback function assigned to the one-shot timer. In this case the
- * // parameter is not used.
- * void vBacklightTimerCallback( xTimerHandle pxTimer )
- * {
- * // The timer expired, therefore 5 seconds must have passed since a key
- * // was pressed. Switch off the LCD back-light.
- * vSetBacklightState( BACKLIGHT_OFF );
- * }
- *
- * // The key press interrupt service routine.
- * void vKeyPressEventInterruptHandler( void )
- * {
- * portBASE_TYPE xHigherPriorityTaskWoken = pdFALSE;
- *
- * // Ensure the LCD back-light is on, then reset the timer that is
- * // responsible for turning the back-light off after 5 seconds of
- * // key inactivity. This is an interrupt service routine so can only
- * // call FreeRTOS API functions that end in "FromISR".
- * vSetBacklightState( BACKLIGHT_ON );
- *
- * // xTimerStartFromISR() or xTimerResetFromISR() could be called here
- * // as both cause the timer to re-calculate its expiry time.
- * // xHigherPriorityTaskWoken was initialised to pdFALSE when it was
- * // declared (in this function).
- * if( xTimerResetFromISR( xBacklightTimer, &xHigherPriorityTaskWoken ) != pdPASS )
- * {
- * // The reset command was not executed successfully. Take appropriate
- * // action here.
- * }
- *
- * // Perform the rest of the key processing here.
