Function Documentation

◆ OS_Sched()

void OS_Sched ( void )

SCHEDULER
This function is called by other uC/OS-II services to determine whether a new, high priority task has been made ready to run. This function is invoked by TASK level code and is not used to reschedule tasks from ISRs (see OSIntExit() for ISR rescheduling).

Warning: 1) This function is INTERNAL to uC/OS-II and your application should not call it.
2) Rescheduling is prevented when the scheduler is locked (see OS_SchedLock())

◆ OS_TCBInit()

INT8U OS_TCBInit	(	INT8U	prio,
		OS_STK *	ptos,
		OS_STK *	pbos,
		INT16U	id,
		INT32U	stk_size,
		void *	pext,
		INT16U	opt
	)

INITIALIZE TCB.

Parameters

prio
ptos
pbos
id
stk_size
pext
opt

Returns: OS_NO_ERR if the call was successful
OS_NO_MORE_TCB if there are no more free TCBs to be allocated and thus, the task cannot be created.

◆ OSCtxSw()

void OSCtxSw ( void )

Switch the context by calling the function directly, since there are no software interrupts in a PIC18 processor.

TASK LEVEL CONTEXT SWITCH
This function is called when a task makes a higher priority task ready-to-run. /*.

TASK CONTEXT SWITCH

Switch the context by calling the function directly, since there are no software interrupts in a PIC18 processor.

TASK LEVEL CONTEXT SWITCH

Description : This function is called when a task makes a higher priority task ready-to-run.

Arguments : none

Note(s) : 1) Upon entry, OSTCBCur points to the OS_TCB of the task to suspend OSTCBHighRdy points to the OS_TCB of the task to resume

2) The stack frame of the task to resume looks as follows:
