ImportantThe stack that you define has to reside in an area that the CPU can actually use as stack. Most CPUs cannot use theentire memory area as stack.Most CPUs require alignment of stack in multiples of bytes. This is automatically done, when the task stack is definedas an array of integers.Example/* Demo-program to illustrate the use of OS_CreateTask */OS_STACKPTR int StackMain[100], StackClock[50];OS_TASK TaskMain,TaskClock;OS_SEMA SemaLCD;void Clock(void) {while(1) {/* Code to update the clock */}}void Main(void) {while (1) {/* Your code */}}void InitTask(void) {OS_CreateTask(&TaskMain, NULL, 50, Main, StackMain, sizeof(StackMain), 2);OS_CreateTask(&TaskClock, NULL, 100, Clock,StackClock,sizeof(StackClock),2);}OS_CREATETASK_EX()DescriptionCreates a task and passes a parameter to the task.Prototypevoid OS_CREATETASK_EX (OS_TASK* pTask,char*pName,void*pRoutine,unsigned char Priority,void*pStack,void*pContext);ParameterDescriptionpTaskpNamepRoutinePrioritypStackpContextTable 6: OS_CREATETASK_EX() parameter listAdditional InformationPointer to a data structure of type OS_TASK which will be used as task control block (andreference) for this task.Pointer to the name of the task.
