+ * main_blinky() creates one queue, and two tasks. It then starts the\r
+ * scheduler.\r
+ *\r
+ * The Queue Send Task:\r
+ * The queue send task is implemented by the prvQueueSendTask() function in\r
+ * this file. prvQueueSendTask() sits in a loop that causes it to repeatedly\r
+ * block for 200 milliseconds, before sending the value 100 to the queue that\r
+ * was created within main_blinky(). Once the value is sent, the task loops\r
+ * back around to block for another 200 milliseconds...and so on.\r
+ *\r
+ * The Queue Receive Task:\r
+ * The queue receive task is implemented by the prvQueueReceiveTask() function\r
+ * in this file. prvQueueReceiveTask() sits in a loop where it repeatedly\r
+ * blocks on attempts to read data from the queue that was created within\r
+ * main_blinky(). When data is received, the task checks the value of the\r
+ * data, and if the value equals the expected 100, toggles an LED. The 'block\r
+ * time' parameter passed to the queue receive function specifies that the\r
+ * task should be held in the Blocked state indefinitely to wait for data to\r
+ * be available on the queue. The queue receive task will only leave the\r
+ * Blocked state when the queue send task writes to the queue. As the queue\r
+ * send task writes to the queue every 200 milliseconds, the queue receive\r
+ * task leaves the Blocked state every 200 milliseconds, and therefore toggles\r
+ * the LED every 200 milliseconds.\r

+ ******************************************************************************\r
+ *\r
+ * main_full() creates all the demo application tasks and software timers, then\r
+ * starts the scheduler. The web documentation provides more details of the\r
+ * standard demo application tasks, which provide no particular functionality,\r
+ * but do provide a good example of how to use the FreeRTOS API.\r
+ *\r
+ * In addition to the standard demo tasks, the following tasks and tests are\r
+ * defined and/or created within this file:\r
+ *\r
+ * "Reg test" tasks - These fill both the core and floating point registers with\r
+ * known values, then check that each register maintains its expected value for\r
+ * the lifetime of the task. Each task uses a different set of values. The reg\r
+ * test tasks execute with a very low priority, so get preempted very\r
+ * frequently. A register containing an unexpected value is indicative of an\r
+ * error in the context switching mechanism.\r
+ *\r
+ * "Check" task - The check task period is initially set to three seconds. The\r
+ * task checks that all the standard demo tasks, and the register check tasks,\r
+ * are not only still executing, but are executing without reporting any errors.\r
+ * If the check task discovers that a task has either stalled, or reported an\r
+ * error, then it changes its own execution period from the initial three\r
+ * seconds, to just 200ms. The check task also toggles an LED each time it is\r
+ * called. This provides a visual indication of the system status: If the LED\r
+ * toggles every three seconds, then no issues have been discovered. If the LED\r
+ * toggles every 200ms, then an issue has been discovered with at least one\r
+ * task.\r
