+/**
+ * Creates two tasks that operate on an interrupt driven serial port. A loopback
+ * connector should be used so that everything that is transmitted is also received.
+ * The serial port does not use any flow control. On a standard 9way 'D' connector
+ * pins two and three should be connected together.
+ *
+ * The first task repeatedly sends a string to a queue, character at a time. The
+ * serial port interrupt will empty the queue and transmit the characters. The
+ * task blocks for a pseudo random period before resending the string.
+ *
+ * The second task blocks on a queue waiting for a character to be received.
+ * Characters received by the serial port interrupt routine are posted onto the
+ * queue - unblocking the task making it ready to execute. If this is then the
+ * highest priority task ready to run it will run immediately - with a context
+ * switch occurring at the end of the interrupt service routine. The task
+ * receiving characters is spawned with a higher priority than the task
+ * transmitting the characters.
+ *
+ * With the loop back connector in place, one task will transmit a string and the
+ * other will immediately receive it. The receiving task knows the string it
+ * expects to receive so can detect an error.
+ *
+ * This also creates a third task. This is used to test semaphore usage from an
+ * ISR and does nothing interesting.

+/**
+ * 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.
+ *
+ *
+ * The final set of two tasks implements a third test. This simply raises the
+ * priority of a task while the scheduler is suspended. Again this test was
+ * added to exercise parts of the code not covered by the first test.

+/**
+ * Creates two sets of two tasks. The tasks within a set share a variable, access
+ * to which is guarded by a semaphore.
+ *
+ * Each task starts by attempting to obtain the semaphore. On obtaining a
+ * semaphore a task checks to ensure that the guarded variable has an expected
+ * value. It then clears the variable to zero before counting it back up to the
+ * expected value in increments of 1. After each increment the variable is checked
+ * to ensure it contains the value to which it was just set. When the starting
+ * value is again reached the task releases the semaphore giving the other task in
+ * the set a chance to do exactly the same thing. The starting value is high
+ * enough to ensure that a tick is likely to occur during the incrementing loop.
+ *
+ * An error is flagged if at any time during the process a shared variable is
+ * found to have a value other than that expected. Such an occurrence would
+ * suggest an error in the mutual exclusion mechanism by which access to the
+ * variable is restricted.
+ *
+ * The first set of two tasks poll their semaphore. The second set use blocking
+ * calls.

+ * This is a very simple queue test. See the BlockQ. c documentation for a more
+ * comprehensive version.
+ *
+ * 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.

+ * Creates six tasks that operate on three queues as follows:
+ *
+ * The first two tasks send and receive an incrementing number to/from a queue.
+ * One task acts as a producer and the other as the consumer. The consumer is a
+ * higher priority than the producer and is set to block on queue reads. The queue
+ * only has space for one item - as soon as the producer posts a message on the
+ * queue the consumer will unblock, pre-empt the producer, and remove the item.
+ *
+ * The second two tasks work the other way around. Again the queue used only has
+ * enough space for one item. This time the consumer has a lower priority than the
+ * producer. The producer will try to post on the queue blocking when the queue is
+ * full. When the consumer wakes it will remove the item from the queue, causing
+ * the producer to unblock, pre-empt the consumer, and immediately re-fill the
+ * queue.
+ *
+ * The last two tasks use the same queue producer and consumer functions. This time the queue has
+ * enough space for lots of items and the tasks operate at the same priority. The
+ * producer will execute, placing items into the queue. The consumer will start
+ * executing when either the queue becomes full (causing the producer to block) or
+ * a context switch occurs (tasks of the same priority will time slice).

+ * This version of comtest. c is for use on systems that have limited stack

+ * the Demo/Common/Full directory.
+ *
+ * Creates two tasks that operate on an interrupt driven serial port. A
+ * loopback connector should be used so that everything that is transmitted is
+ * also received. The serial port does not use any flow control. On a
+ * standard 9way 'D' connector pins two and three should be connected together.
+ *
+ * The first task posts a sequence of characters to the Tx queue, toggling an
+ * LED on each successful post. At the end of the sequence it sleeps for a
+ * pseudo-random period before resending the same sequence.
+ *
+ * The UART Tx end interrupt is enabled whenever data is available in the Tx
+ * queue. The Tx end ISR removes a single character from the Tx queue and
+ * passes it to the UART for transmission.
+ *
+ * The second task blocks on the Rx queue waiting for a character to become
+ * available. When the UART Rx end interrupt receives a character it places
+ * it in the Rx queue, waking the second task. The second task checks that the
+ * characters removed from the Rx queue form the same sequence as those posted
+ * to the Tx queue, and toggles an LED for each correct character.
+ *
+ * The receiving task is spawned with a higher priority than the transmitting
+ * task. The receiver will therefore wake every time a character is
+ * transmitted so neither the Tx or Rx queue should ever hold more than a few
+ * characters.

+ * This demo application file demonstrates the use of queues to pass data

+ *
+ * N represents the number of 'fixed delay' co-routines that are created and
+ * is set during initialisation.
+ *
+ * N 'fixed delay' co-routines are created that just block for a fixed
+ * period then post the number of an LED onto a queue. Each such co-routine
+ * uses a different block period. A single 'flash' co-routine is also created
+ * that blocks on the same queue, waiting for the number of the next LED it
+ * should flash. Upon receiving a number it simply toggle the instructed LED
+ * then blocks on the queue once more. In this manner each LED from LED 0 to
+ * LED N-1 is caused to flash at a different rate.
+ *
+ * The 'fixed delay' co-routines are created with co-routine priority 0. The

+/*
+ * 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.

+ * This demo file demonstrates how to send data between an ISR and a
+ * co-routine. A tick hook function is used to periodically pass data between
+ * the RTOS tick and a set of 'hook' co-routines.
+ *
+ * hookNUM_HOOK_CO_ROUTINES co-routines are created. Each co-routine blocks
+ * to wait for a character to be received on a queue from the tick ISR, checks
+ * to ensure the character received was that expected, then sends the number
+ * back to the tick ISR on a different queue.
+ *
+ * The tick ISR checks the numbers received back from the 'hook' co-routines
+ * matches the number previously sent.
+ *
+ * If at any time a queue function returns unexpectedly, or an incorrect value
+ * is received either by the tick hook or a co-routine then an error is
+ * latched.
+ *
+ * This demo relies on each 'hook' co-routine to execute between each
+ * hookTICK_CALLS_BEFORE_POST tick interrupts. This and the heavy use of
+ * queues from within an interrupt may result in an error being detected on
+ * slower targets simply due to timing.

+ The tasks defined on this page demonstrate the use of recursive mutexes.
+
+ For recursive mutex functionality the created mutex should be created using
+ xSemaphoreCreateRecursiveMutex(), then be manipulated
+ using the xSemaphoreTakeRecursive() and xSemaphoreGiveRecursive() API
+ functions.
+
+ This demo creates three tasks all of which access the same recursive mutex:
+
+ prvRecursiveMutexControllingTask() has the highest priority so executes
+ first and grabs the mutex. It then performs some recursive accesses -
+ between each of which it sleeps for a short period to let the lower
+ priority tasks execute. When it has completed its demo functionality
+ it gives the mutex back before suspending itself.
+
+ prvRecursiveMutexBlockingTask() attempts to access the mutex by performing
+ a blocking 'take'. The blocking task has a lower priority than the
+ controlling task so by the time it executes the mutex has already been
+ taken by the controlling task, causing the blocking task to block. It
+ does not unblock until the controlling task has given the mutex back,
+ and it does not actually run until the controlling task has suspended
+ itself (due to the relative priorities). When it eventually does obtain
+ the mutex all it does is give the mutex back prior to also suspending
+ itself. At this point both the controlling task and the blocking task are
+ suspended.
+
+ prvRecursiveMutexPollingTask() runs at the idle priority. It spins round
+ a tight loop attempting to obtain the mutex with a non-blocking call. As
+ the lowest priority task it will not successfully obtain the mutex until
+ both the controlling and blocking tasks are suspended. Once it eventually
+ does obtain the mutex it first unsuspends both the controlling task and
+ blocking task prior to giving the mutex back - resulting in the polling
+ task temporarily inheriting the controlling tasks priority.

+ * This is a version of BlockQ.c that uses the alternative (Alt) API.
+ *
+ * Creates six tasks that operate on three queues as follows:
+ *
+ * The first two tasks send and receive an incrementing number to/from a queue.
+ * One task acts as a producer and the other as the consumer. The consumer is a
+ * higher priority than the producer and is set to block on queue reads. The queue
+ * only has space for one item - as soon as the producer posts a message on the
+ * queue the consumer will unblock, pre-empt the producer, and remove the item.
+ *
+ * The second two tasks work the other way around. Again the queue used only has
+ * enough space for one item. This time the consumer has a lower priority than the
+ * producer. The producer will try to post on the queue blocking when the queue is
+ * full. When the consumer wakes it will remove the item from the queue, causing
+ * the producer to unblock, pre-empt the consumer, and immediately re-fill the
+ * queue.
+ *
+ * The last two tasks use the same queue producer and consumer functions. This time the queue has
+ * enough space for lots of items and the tasks operate at the same priority. The
+ * producer will execute, placing items into the queue. The consumer will start
+ * executing when either the queue becomes full (causing the producer to block) or
+ * a context switch occurs (tasks of the same priority will time slice).
