+/******************************************************************************\r
+ * NOTE 1: This project provides two demo applications. A simple blinky\r
+ * style project, and a more comprehensive test and demo application. The\r
+ * mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting in main.c is used to select\r
+ * between the two. See the notes on using mainCREATE_SIMPLE_BLINKY_DEMO_ONLY\r
+ * in main.c. This file implements the simply blinky style version.\r
+ *\r
+ * NOTE 2: This file only contains the source code that is specific to the\r
+ * basic demo. Generic functions, such FreeRTOS hook functions, and functions\r
+ * required to configure the hardware are defined in main.c.\r
+ ******************************************************************************\r
+ *\r
+ * 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 1000 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 1000 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, writes 'Blink' to the UART\r
+ * (the UART is used in place of the LED to allow easy execution in QEMU). The\r
+ * 'block time' parameter passed to the queue receive function specifies that\r
+ * the 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 1000 milliseconds, the queue receive\r
+ * task leaves the Blocked state every 1000 milliseconds, and therefore toggles\r
+ * the LED every 200 milliseconds.\r

+ * NOTE 1: This project provides two demo applications. A simple blinky style\r
+ * project, and a more comprehensive test and demo application. The\r
+ * mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting in main.c is used to select\r
+ * between the two. See the notes on using mainCREATE_SIMPLE_BLINKY_DEMO_ONLY\r
+ * in main.c. This file implements the comprehensive test and demo version.\r
+ *\r
+ * NOTE 2: This file only contains the source code that is specific to the\r
+ * full demo. Generic functions, such FreeRTOS hook functions, and functions\r
+ * required to configure the hardware, are defined in main.c.\r
+ *\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 registers with known values, then\r
+ * check that each register maintains its expected value for the lifetime of the\r
+ * task. Each task uses a different set of values. The reg test tasks execute\r
+ * with a very low priority, so get preempted very frequently. A register\r
+ * containing an unexpected value is indicative of an error in the context\r
+ * switching mechanism.\r
+ *\r
+ * "Check" task - The check executes every five seconds. It checks that all\r
+ * the standard demo tasks, and the register check tasks, are not only still\r
+ * executing, but are executing without reporting any errors. If the check task\r
+ * discovers that a task has either stalled, or reported an error, then it\r
+ * prints an error message to the UART, otherwise it prints "Pass.".\r
