+ *\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 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.\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 the 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
+ * 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

+ * 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" timer - The check software timer period is initially set to three\r
+ * seconds. The callback function associated with the check software timer\r
+ * checks that all the standard demo tasks, and the register check tasks, are\r
+ * not only still executing, but are executing without reporting any errors. If\r
+ * the check software timer discovers that a task has either stalled, or\r
+ * reported an error, then it changes its own execution period from the initial\r
+ * three seconds, to just 200ms. The check software timer callback function\r
+ * also toggles the single LED each time it is called. This provides a visual\r
+ * indication of the system status: If the LED toggles every three seconds,\r
+ * then no issues have been discovered. If the LED toggles every 200ms, then\r
+ * an issue has been discovered with at least one task.\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 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 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.\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 the 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

- * 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" timer - The check software timer period is initially set to three\r
- * seconds. The callback function associated with the check software timer\r
- * checks that all the standard demo tasks, and the register check tasks, are\r
- * not only still executing, but are executing without reporting any errors. If\r
- * the check software timer discovers that a task has either stalled, or\r
- * reported an error, then it changes its own execution period from the initial\r
- * three seconds, to just 200ms. The check software timer callback function\r
- * also toggles the single LED each time it is called. This provides a visual\r
- * indication of the system status: If the LED toggles every three seconds,\r
- * then no issues have been discovered. If the LED toggles every 200ms, then\r
- * an issue has been discovered with at least one task.\r
