/*
Changes from V3.2.3
+ Modified portENTER_SWITCHING_ISR() to allow use with GCC V4.0.1.
Changes from V3.2.4
+ Removed the use of the %0 parameter within the assembler macros and
replaced them with hard coded registers. This will ensure the
assembler does not select the link register as the temp register as
was occasionally happening previously.
+ The assembler statements are now included in a single asm block rather
than each line having its own asm block.
Changes from V4.5.0
+ Removed the portENTER_SWITCHING_ISR() and portEXIT_SWITCHING_ISR() macros
and replaced them with portYIELD_FROM_ISR() macro. Application code
should now make use of the portSAVE_CONTEXT() and portRESTORE_CONTEXT()
macros as per the V4.5.1 demo code.

* 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.

*
* vTaskDelay() specifies a time at which the task wishes to unblock relative to
* the time at which vTaskDelay() is called. For example, specifying a block
* period of 100 ticks will cause the task to unblock 100 ticks after
* vTaskDelay() is called. vTaskDelay() does not therefore provide a good method
* of controlling the frequency of a cyclical task as the path taken through the

* at which vTaskDelay() gets called and therefore the time at which the task
* next executes. See vTaskDelayUntil() for an alternative API function designed
* to facilitate fixed frequency execution. It does this by specifying an
* absolute time (rather than a relative time) at which the calling task should
* unblock.

* code between calls, or may get interrupted or preempted a different number of times
* each time it executes].
*
* Whereas vTaskDelay () specifies a wake time relative to the time at which the function
* is called, vTaskDelayUntil () specifies the absolute (exact) time at which it wishes to

*
* <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'.
*
* @param uxInitialCount The count value assigned to the semaphore when it is
* created.
*
* @return Handle to the created semaphore. Null if the semaphore could not be
* created.
*
* Example usage:
<pre>
xSemaphoreHandle xSemaphore;

xSemaphoreHandle xSemaphore = NULL;
// Semaphore cannot be used before a call to xSemaphoreCreateCounting().

/**
* xTimerHandle xTimerCreate( const signed char *pcTimerName,
* portTickType xTimerPeriod,
* 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 xTimerPeriod 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 xTimerPeriod 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 xTimerPeriod 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.

*
*

* // 10 times.

*
* Post an item to the back of a queue. It is safe to use this function from
* within an interrupt service routine.
*
* Items are queued by copy not reference so it is preferable to only
* queue small items, especially when called from an ISR. In most cases
* it would be preferable to store a pointer to the item being queued.
*
* @param xQueue The handle to the queue on which the item is to be posted.
*
* @param pvItemToQueue A pointer to the item that is to be placed on the
* queue. The size of the items the queue will hold was defined when the
* queue was created, so this many bytes will be copied from pvItemToQueue
* into the queue storage area.
*
* @param pxHigherPriorityTaskWoken xQueueSendFromISR() will set
* *pxHigherPriorityTaskWoken to pdTRUE if sending to the queue caused a task
* to unblock, and the unblocked task has a priority higher than the currently
* running task. If xQueueSendFromISR() sets this value to pdTRUE then
* a context switch should be requested before the interrupt is exited.
*

* The macro's crQUEUE_SEND() and crQUEUE_RECEIVE() are the co-routine
* equivalent to the xQueueSend() and xQueueReceive() functions used by tasks.
*
* crQUEUE_SEND and crQUEUE_RECEIVE can only be used from a co-routine whereas
* xQueueSend() and xQueueReceive() can only be used from tasks.
*
* crQUEUE_RECEIVE can only be called from the co-routine function itself - not
* from within a function called by the co-routine function. This is because
* co-routines do not maintain their own stack.
*
* See the co-routine section of the WEB documentation for information on
* passing data between tasks and co-routines and between ISR's and
* co-routines.
*
* @param xHandle The handle of the calling co-routine. This is the xHandle
* parameter of the co-routine function.
*
* @param pxQueue The handle of the queue from which the data will be received.
* The handle is obtained as the return value when the queue is created using
* the xQueueCreate() API function.
*
* @param pvBuffer The buffer into which the received item is to be copied.
* The number of bytes of each queued item is specified when the queue is
* created. This number of bytes is copied into pvBuffer.
*
* @param xTickToDelay The number of ticks that the co-routine should block
* to wait for data to become available from the queue, should data not be
* available immediately. The actual amount of time this equates to is defined
* by configTICK_RATE_HZ (set in FreeRTOSConfig.h). The constant
* portTICK_RATE_MS can be used to convert ticks to milliseconds (see the
* crQUEUE_SEND example).
*
* @param pxResult The variable pointed to by pxResult will be set to pdPASS if
* data was successfully retrieved from the queue, otherwise it will be set to
* an error code as defined within ProjDefs.h.
*
* Example usage:
<pre>
// A co-routine receives the number of an LED to flash from a queue. It
// blocks on the queue until the number is received.

<h1>
CKEditor Installation Guide</h1>
<h3>
What's CKEditor?</h3>
<p>
CKEditor is a text editor to be used inside web pages. It's not a replacement
for desktop text editors like Word or OpenOffice, but a component to be used as
part of web applications and web sites.</p>
<h3>
Installation</h3>
<p>
Installing CKEditor is an easy task. Just follow these simple steps:</p>
<ol>
<li><strong>Download</strong> the latest version of the editor from our web site: <a
href="http://ckeditor.com">http://ckeditor.com</a>. You should have already completed
this step, but be sure you have the very latest version.</li>
<li><strong>Extract</strong> (decompress) the downloaded file into the root of your
web site.</li>
</ol>
<p>
<strong>Note:</strong> CKEditor is by default installed in the "ckeditor"
folder. You can place the files in whichever you want though.</p>
<h3>
Checking Your Installation
</h3>
<p>
The editor comes with a few sample pages that can be used to verify that installation
proceeded properly. Take a look at the <a href="_samples">_samples</a> directory.</p>
<p>
To test your installation, just call the following page at your web site:</p>
<pre>
http://<your site>/<CKEditor installation path>/_samples/index.html
For example:
http://www.example.com/ckeditor/_samples/index.html</pre>
<h3>
Documentation</h3>
<p>
The full editor documentation is available online at the following address:<br />
<a href="http://docs.cksource.com/ckeditor">http://docs.cksource.com/ckeditor</a></p>
