Also, at the time of writing, a method of deleting theads + * has not been implemented, although doing so would be trivial so this + * functionality might be added in at a later date.

If an error is discovered in the execution of a task then the check + * task will print out an appropriate error message. + * + */ + + +/* Standard includes. */ +#include + +/* Kernel includes. */ +#include +#include "task.h" +#include "queue.h" + +/* Standard demo includes. */ +#include "BlockQ.h" +#include "integer.h" +#include "semtest.h" +#include "PollQ.h" +#include "GenQTest.h" +#include "QPeek.h" +#include "recmutex.h" +#include "flop.h" + +/* Priorities at which the tasks are created. */ +#define mainCHECK_TASK_PRIORITY ( configMAX_PRIORITIES - 1 ) +#define mainQUEUE_POLL_PRIORITY ( tskIDLE_PRIORITY + 1 ) +#define mainSEM_TEST_PRIORITY ( tskIDLE_PRIORITY + 1 ) +#define mainBLOCK_Q_PRIORITY ( tskIDLE_PRIORITY + 2 ) +#define mainCREATOR_TASK_PRIORITY ( tskIDLE_PRIORITY + 3 ) +#define mainFLASH_TASK_PRIORITY ( tskIDLE_PRIORITY + 1 ) +#define mainuIP_TASK_PRIORITY ( tskIDLE_PRIORITY + 2 ) +#define mainINTEGER_TASK_PRIORITY ( tskIDLE_PRIORITY ) +#define mainGEN_QUEUE_TASK_PRIORITY ( tskIDLE_PRIORITY ) +#define mainFLOP_TASK_PRIORITY ( tskIDLE_PRIORITY ) + +/* Task function prototypes. */ +static void prvCheckTask( void *pvParameters ); + +/*-----------------------------------------------------------*/ + +int main( void ) +{ + /* Start the check task as described at the top of this file. */ + xTaskCreate( prvCheckTask, ( signed char * ) "Check", configMINIMAL_STACK_SIZE, NULL, mainCHECK_TASK_PRIORITY, NULL ); + + /* Create the standard demo tasks. */ + vStartBlockingQueueTasks( mainBLOCK_Q_PRIORITY ); + vStartSemaphoreTasks( mainSEM_TEST_PRIORITY ); + vStartPolledQueueTasks( mainQUEUE_POLL_PRIORITY ); + vStartIntegerMathTasks( mainINTEGER_TASK_PRIORITY ); + vStartGenericQueueTasks( mainGEN_QUEUE_TASK_PRIORITY ); + vStartQueuePeekTasks(); + vStartMathTasks( mainFLOP_TASK_PRIORITY ); + vStartRecursiveMutexTasks(); + + /* Start the scheduler itself. */ + vTaskStartScheduler(); + + /* Should never get here unless there was not enough heap space to create + the idle and other system tasks. */ + return 0; +} +/*-----------------------------------------------------------*/ + +static void prvCheckTask( void *pvParameters ) +{ +portTickType xNextWakeTime; +const portTickType xCycleFrequency = 5000 / portTICK_RATE_MS; +char *pcStatusMessage = "OK"; + + /* Just to remove compiler warning. */ + ( void ) pvParameters; + + /* Initialise xNextWakeTime - this only needs to be done once. */ + xNextWakeTime = xTaskGetTickCount(); + + for( ;; ) + { + /* Place this task in the blocked state until it is time to run again. */ + vTaskDelayUntil( &xNextWakeTime, xCycleFrequency ); + + /* Check the standard demo tasks are running without error. */ + if( xAreIntegerMathsTaskStillRunning() != pdTRUE ) + { + pcStatusMessage = "Error: IntMath"; + } + else if( xAreGenericQueueTasksStillRunning() != pdTRUE ) + { + pcStatusMessage = "Error: GenQueue"; + } + else if( xAreQueuePeekTasksStillRunning() != pdTRUE ) + { + pcStatusMessage = "Error: QueuePeek"; + } + else if( xAreBlockingQueuesStillRunning() != pdTRUE ) + { + pcStatusMessage = "Error: BlockQueue"; + } + else if( xAreSemaphoreTasksStillRunning() != pdTRUE ) + { + pcStatusMessage = "Error: SemTest"; + } + else if( xArePollingQueuesStillRunning() != pdTRUE ) + { + pcStatusMessage = "Error: PollQueue"; + } + else if( xAreMathsTaskStillRunning() != pdPASS ) + { + pcStatusMessage = "Error: Flop"; + } + else if( xAreRecursiveMutexTasksStillRunning() != pdTRUE ) + { + pcStatusMessage = "Error: RecMutex"; + } + + /* This is the only task that uses stdout so its ok to call printf() + directly. */ + printf( "%s - %d\r\n", pcStatusMessage, ( int ) xTaskGetTickCount() ); + fflush( stdout ); /* Required by Eclipse console. */ + } +} +/*-----------------------------------------------------------*/ + +void vApplicationIdleHook( void ) +{ + /* Sleep to reduce CPU load, but don't sleep indefinitely if not using + preemption as as nothing will cause a task switch. */ + #if( configUSE_PREEMPTION != 0 ) + { + SleepEx( INFINITE, TRUE ); + } + #else + { + const unsigned long ulMSToSleep = 5; + + SleepEx( ulMSToSleep, TRUE ); + } + #endif +} +/*-----------------------------------------------------------*/ + +void vApplicationMallocFailedHook( void ) +{ + /* Can be implemented if required, but probably not required in this + environment and running this demo. */ +} +/*-----------------------------------------------------------*/ + +void vApplicationStackOverflowHook( void ) +{ + /* Can be implemented if required, but not required in this + environment and running this demo. */ +} + -- 2.39.5
