Changes to the FreeRTOS code:
+ Introduced xTaskCreateStatic() to allow tasks to be created without any dynamic memory allocation. + When a task notification is used to unblock a task from an ISR, but the xHigherPriorityTaskWoken parameter is not used, then pend a context switch to occur during the next tick interrupt. Demo application changes: + Updated TaskNotify.c to test the case where a task is unblocked by an ISR, but does not use its xHigherPriorityTaskWoken parameter. + Updated the Win32 MSVC project to test statically allocated tasks being created and deleted. + Introduced StaticAllocation.c standard demo task.

|
||||
* facilitate debugging. The maximum length of the string is defined by
|
||||
* configMAX_TASK_NAME_LEN in FreeRTOSConfig.h.
|
||||
*
|
||||
* @param usStackDepth The size of the task stack specified as the number of
|
||||
* variables the stack can hold - not the number of bytes. For example, if
|
||||
* the stack is 32-bits wide and usStackDepth is defined as 100 then 400 bytes
|
||||
* will be allocated for stack storage.
|
||||
*
|
||||
* @param pvParameters Pointer that will be used as the parameter for the task
|
||||
* being created.
|
||||
*
|
||||
* @param uxPriority The priority at which the task will run.
|
||||
*
|

* @param pvCreatedTask Used to pass back a handle by which the created task
|
||||
* can be referenced. Pass as NULL if the handle is not required.
|
||||
*
|
||||
* @param pxStackBuffer If pxStackBuffer is NULL then the stack used by the
|
||||
* task will be allocated dynamically, just as if the task was created using
|
||||
* xTaskCreate(). if pxStackBuffer is not NULL then it must point to a
|
||||
* StackType_t array that has at least usStackDepth indexes - the array will
|
||||
* then be used as the task's stack.
|
||||
*
|
||||
* @param pxTCBBuffer If pxTCBBuffer is NULL then the TCB (which is the
|
||||
* structures used internally within FreeRTOS to hold information on the task)
|
||||
* will be allocated dynamically, just as when xTaskCreate() is used. If
|
||||
* pxTCBBuffer is not NULL then it must point to a variable of type DummyTCB_T,
|
||||
* which will then be used as the TCB of the task being created.
|
||||
*
|
||||
* @return pdPASS if the task was successfully created and added to a ready
