08 FreeRTOS Tutorial: Task Utilities part2

이번 시간에는 TaskState에 대해 받아오는 것을 해본다.

void myTask1(void *pvParameters)
{

	TickType_t xDelay = pdMS_TO_TICKS(1000);
	TickType_t myLastUnblock;
	myLastUnblock = xTaskGetTickCount();
	//char* text = "Task1\r\n";
	//char* text = pcTaskGetName(myTask1Handle);
	char* text = "Task1";

	int count = 0;
	vTaskSuspend(myTask1Handle);

		for(;;)
		{


			vTaskDelayUntil( &myLastUnblock, xDelay );



			count ++;



		}
}

void myTask2(void *pvParameters)
{

	TickType_t xDelay = pdMS_TO_TICKS(1000);
	TickType_t myLastUnblock;
	myLastUnblock = xTaskGetTickCount();


		for(;;)
		{

			eTaskState myState;
			myState = eTaskGetState(myTask1Handle);
			printf("the state of task 1 is %d\r\n", myState)
			myState = eTaskGetState(myTask2Handle);
			printf("the state of task 2 is %d\r\n", myState)

			vTaskDelayUntil( &myLastUnblock, xDelay );
		}
}

  

를 완료하면 Task2 에서 Task1 과 Task2 의 상태를 알려준다. 

0 : Running , 1 : Ready , 2 : Blocked , 3 : Suspended , 4 : Deleted 

 

 

char myTaskList[300];

void myTask1(void *pvParameters)
{

	TickType_t xDelay = pdMS_TO_TICKS(1000);
	TickType_t myLastUnblock;
	myLastUnblock = xTaskGetTickCount();
	char* text = "Task1";

	int count = 0;
	vTaskSuspend(myTask1Handle);

		for(;;)
		{

			vTaskDelayUntil( &myLastUnblock, xDelay );
			count ++;

		}
}

void myTask2(void *pvParameters)
{

	TickType_t xDelay = pdMS_TO_TICKS(1000);
	TickType_t myLastUnblock;
	myLastUnblock = xTaskGetTickCount();


		for(;;)
		{

			vTaskList(myTaskList);
            printf("%s\r\n", myTaskList);
			vTaskDelayUntil( &myLastUnblock, xDelay );
            
		}
}

 

다음은 vTaskList() 이다. 이를 출력하면 

 

 

이렇게 프린트 된다. X 는 Running R은 Ready B는 Blocked S는 Suspend B는 Blocked 이다.

 

3번째 열은 priority 4번째 열은 Stack Size 5번째 열은 실행될 Serial order 이다.

 

char myTaskList[300];

void myTask1(void *pvParameters)
{

	TickType_t xDelay = pdMS_TO_TICKS(1000);
	TickType_t myLastUnblock;
	myLastUnblock = xTaskGetTickCount();
	char* text = "Task1";

	int count = 0;
	vTaskSuspend(myTask1Handle);

		for(;;)
		{

			vTaskDelayUntil( &myLastUnblock, xDelay );
			count ++;

		}
}

void myTask2(void *pvParameters)
{

	TickType_t xDelay = pdMS_TO_TICKS(1000);
	TickType_t myLastUnblock;
	myLastUnblock = xTaskGetTickCount();


		for(;;)
		{

			vTaskList(myTaskList);
            
            printf("The total no of tasks running: %d\r\n", uxTaskGetNumberOfTasks());
            //존재하는 Task 수
            printf("The total tick : %d\r\n", xTaskGetTickCount());
            //소요되는 Total Tick
            
            
			vTaskDelayUntil( &myLastUnblock, xDelay );
            
		}
}
