按照以前的方法开打FREE RTOS的例程。
则可以看出这个例程跑两个线程：
一个LED闪，一个打印当前运行的线程。
其中，定义两个线程的堆栈如下：
- #define TASK_MONITOR_STACK_SIZE (2048/sizeof(portSTACK_TYPE))
- #define TASK_MONITOR_STACK_PRIORITY (tskIDLE_PRIORITY)
- #define TASK_LED_STACK_SIZE (1024/sizeof(portSTACK_TYPE))
- #define TASK_LED_STACK_PRIORITY (tskIDLE_PRIORITY)
- **
- * \brief This task, when activated, send every ten seconds on debug UART
- * the whole report of free heap and total tasks status
- */
- static void task_monitor(void *pvParameters)
- {
- static portCHAR szList[256];
- UNUSED(pvParameters);
- for (;;) {
- printf("--- task ## %u", (unsigned int)uxTaskGetNumberOfTasks());
- vTaskList((signed portCHAR *)szList);
- printf(szList);
- vTaskDelay(1000);
- }
- }
- /**
- * \brief This task, when activated, make LED blink at a fixed rate
- */
- static void task_led(void *pvParameters)
- {
- UNUSED(pvParameters);
- for (;;) {
- #if SAM4CM
- LED_Toggle(LED4);
- #else
- LED_Toggle(LED0);
- #endif
- vTaskDelay(1000);
- }
- }
- /* Create task to monitor processor activity */
- if (xTaskCreate(task_monitor, "Monitor", TASK_MONITOR_STACK_SIZE, NULL,
- TASK_MONITOR_STACK_PRIORITY, NULL) != pdPASS) {
- printf("Failed to create Monitor task\r\n");
- }
- /* Create task to make led blink */
- if (xTaskCreate(task_led, "Led", TASK_LED_STACK_SIZE, NULL,
- TASK_LED_STACK_PRIORITY, NULL) != pdPASS) {
- printf("Failed to create test led task\r\n");
- }
- /* Start the scheduler. */
- vTaskStartScheduler();
运行结果：
灯一闪一闪并在闪的同时打印出如下信息：
