* This version of PollQ. c is for use on systems that have limited stack
* space and no display facilities. The complete version can be found in
* the Demo/Common/Full directory.
*
* Creates two tasks that communicate over a single queue. One task acts as a
* producer, the other a consumer.
*
* The producer loops for three iteration, posting an incrementing number onto the
* queue each cycle. It then delays for a fixed period before doing exactly the
* same again.
*
* The consumer loops emptying the queue. Each item removed from the queue is
* checked to ensure it contains the expected value. When the queue is empty it
* blocks for a fixed period, then does the same again.
*
* All queue access is performed without blocking. The consumer completely empties
* the queue each time it runs so the producer should never find the queue full.
*
* An error is flagged if the consumer obtains an unexpected value or the producer
* find the queue is full.

/*
* The first test creates three tasks - two counter tasks (one continuous count
* and one limited count) and one controller. A "count" variable is shared
* between all three tasks. The two counter tasks should never be in a "ready"
* state at the same time. The controller task runs at the same priority as
* the continuous count task, and at a lower priority than the limited count
* task.
*
* One counter task loops indefinitely, incrementing the shared count variable
* on each iteration. To ensure it has exclusive access to the variable it
* raises it's priority above that of the controller task before each
* increment, lowering it again to it's original priority before starting the
* next iteration.
*
* The other counter task increments the shared count variable on each
* iteration of it's loop until the count has reached a limit of 0xff - at
* which point it suspends itself. It will not start a new loop until the
* controller task has made it "ready" again by calling vTaskResume ().
* This second counter task operates at a higher priority than controller
* task so does not need to worry about mutual exclusion of the counter
* variable.
*
* The controller task is in two sections. The first section controls and
* monitors the continuous count task. When this section is operational the
* limited count task is suspended. Likewise, the second section controls
* and monitors the limited count task. When this section is operational the
* continuous count task is suspended.
*
* In the first section the controller task first takes a copy of the shared
* count variable. To ensure mutual exclusion on the count variable it
* suspends the continuous count task, resuming it again when the copy has been
* taken. The controller task then sleeps for a fixed period - during which
* the continuous count task will execute and increment the shared variable.
* When the controller task wakes it checks that the continuous count task
* has executed by comparing the copy of the shared variable with its current
* value. This time, to ensure mutual exclusion, the scheduler itself is
* suspended with a call to vTaskSuspendAll (). This is for demonstration
* purposes only and is not a recommended technique due to its inefficiency.
*
* After a fixed number of iterations the controller task suspends the
* continuous count task, and moves on to its second section.
*
* At the start of the second section the shared variable is cleared to zero.
* The limited count task is then woken from it's suspension by a call to
* vTaskResume (). As this counter task operates at a higher priority than
* the controller task the controller task should not run again until the
* shared variable has been counted up to the limited value causing the counter
* task to suspend itself. The next line after vTaskResume () is therefore
* a check on the shared variable to ensure everything is as expected.
*
*
* The second test consists of a couple of very simple tasks that post onto a
* queue while the scheduler is suspended. This test was added to test parts
* of the scheduler not exercised by the first test.
