CMSIS : Cortex Microcontroller Software Interface Standard
==========================================================
Introduction
~~~~~~~~~~~~
CMSIS defines for a Cortex-M Microcontroller System:
* A common way to access peripheral registers and a
common way to define exception vectors.
* The register names of the Core Peripherals and the
names of the Core Exception Vectors.
* An device independent interface for RTOS Kernels
including a debug channel.
By using CMSIS compliant software components, the user can
easier re-use template code. CMSIS is intended to enable the
combination of software components from multiple middleware
vendors.
This project contains appropriate files for this MCU family
taken from CMSIS. A full copy of the CMSIS files, together
with additional information on CMSIS can be found at:
http://www.onarm.com/

Documentation
~~~~~~~~~~~~~
The standard CMSIS documentation can be found within the
Code Red IDE help system, via:
Help -> Help Contents -> Code Red Product Documentation -> CMSIS
More information on the use of CMSIS within the Code Red IDE
can be found in the Support area of the Code Red website at
http://www.code-red-tech.com/
At the time of writing, the CMSIS FAQ can be found directly

/*
* 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 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 the list implementation used by the scheduler. While it is tailored
* heavily for the schedulers needs, it is also available for use by
* application code.
*
* xLists can only store pointers to xListItems. Each xListItem contains a
* numeric value (xItemValue). Most of the time the lists are sorted in
* descending item value order.
*
* Lists are created already containing one list item. The value of this
* item is the maximum possible that can be stored, it is therefore always at
* the end of the list and acts as a marker. The list member pxHead always
* points to this marker - even though it is at the tail of the list. This
* is because the tail contains a wrap back pointer to the true head of
* the list.
*
* In addition to it's value, each list item contains a pointer to the next
* item in the list (pxNext), a pointer to the list it is in (pxContainer)
* and a pointer to back to the object that contains it. These later two
* pointers are included for efficiency of list manipulation. There is
* effectively a two way link between the object containing the list item and
* the list item itself.

*
* <i>Macro</i> 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'.

* reference the subject timer in calls to other software timer API functions
* (for example, xTimerStart(), xTimerReset(), etc.).
*/
typedef void * xTimerHandle;
/* Define the prototype to which timer callback functions must conform. */
typedef void (*tmrTIMER_CALLBACK)( xTimerHandle xTimer );
/**
* xTimerHandle xTimerCreate( const signed char *pcTimerName,
* 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.
*
* Example usage:
*
* #define NUM_TIMERS 5
*
* // An array to hold handles to the created timers.
* xTimerHandle xTimers[ NUM_TIMERS ];
*
* // An array to hold a count of the number of times each timer expires.
* long lExpireCounters[ NUM_TIMERS ] = { 0 };
*
* // Define a callback function that will be used by multiple timer instances.
* // The callback function does nothing but count the number of times the
* // associated timer expires, and stop the timer once the timer has expired
* // 10 times.

* // without a key being pressed, then the LCD back-light is switched off. In

* // 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.
*
* // If xHigherPriorityTaskWoken equals pdTRUE, then a context switch

If you find your application is crashing here then likely causes are:
1) Stack overflow -
see http://www.freertos.org/Stacks-and-stack-overflow-checking.html
2) Incorrect interrupt priority assignment, especially on Cortex-M3
parts where numerically high priority values denote low actual
interrupt priories, which can seem counter intuitive. See
configMAX_SYSCALL_INTERRUPT_PRIORITY on http://www.freertos.org/a00110.html
3) Calling an API function from within a critical section or when
the scheduler is suspended.
4) Using a queue or semaphore before it has been initialised or
before the scheduler has been started (are interrupts firing
before vTaskStartScheduler() has been called?).
See http://www.freertos.org/FAQHelp.html for more tips.
