Priority set

Posted by krishna kumar on March 5, 2008
Hello,
WE doing the finger print project in imx27,i am working on freeRTOS in embedded workbeanch tools,As i checking the working of priority set by creating task1&2 where task2 has higher priority,i raise the priority of first task to priority of second task by priority set of taskhandle but priority of first task is not raised to second task how we can do this...can anyone suggest me

static xHandle xHandle3

mainTASK2_PRIORITY 3
mainTASK3_PRIORITY 4

static void TASK2( void * pvParameters )
{
for(;;)
{

vTaskPrioritySet( xHandle3, mainTASK2_PRIORITY+1);
{
if(mainTASK2_PRIORITY==4)//bt it not entering to this loop where task2 is raised from
priority 3 to 4
{

some code

}
}
}

I don't follow the code: "if(mainTASK2_PRIORITY==4)" as mainTASK2_PRIORITY is 3 (a manifest constant) it will never equal 4.

If you want examples of raising and lowering task priorities look at FreeRTOS\Demo\Common\Minimal\dynamic.c.

Regards.
