-/******************************************************************************

- * NOTE 1:  This project provides two demo applications.  A simple blinky

- * style project, and a more comprehensive test and demo application.  The

- * mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting in main.c is used to select

- * between the two.  See the notes on using mainCREATE_SIMPLE_BLINKY_DEMO_ONLY

- * in main.c.  This file implements the simply blinky style version.

- *

- * NOTE 2:  This file only contains the source code that is specific to the

- * basic demo.  Generic functions, such FreeRTOS hook functions, and functions

- * required to configure the hardware are defined in main.c.

- ******************************************************************************

- *

- * main_blinky() creates one queue, and two tasks.  It then starts the

- * scheduler.

- *

- * The Queue Send Task:

- * The queue send task is implemented by the prvQueueSendTask() function in

- * this file.  prvQueueSendTask() sits in a loop that causes it to repeatedly

- * block for 1000 milliseconds, before sending the value 100 to the queue that

- * was created within main_blinky().  Once the value is sent, the task loops

- * back around to block for another 1000 milliseconds...and so on.

- *

- * The Queue Receive Task:

- * The queue receive task is implemented by the prvQueueReceiveTask() function

- * in this file.  prvQueueReceiveTask() sits in a loop where it repeatedly

- * blocks on attempts to read data from the queue that was created within

- * main_blinky().  When data is received, the task checks the value of the

- * data, and if the value equals the expected 100, writes 'Blink' to the UART

- * (the UART is used in place of the LED to allow easy execution in QEMU).  The

- * 'block time' parameter passed to the queue receive function specifies that

- * the task should be held in the Blocked state indefinitely to wait for data to

- * be available on the queue.  The queue receive task will only leave the

- * Blocked state when the queue send task writes to the queue.  As the queue

- * send task writes to the queue every 1000 milliseconds, the queue receive

- * task leaves the Blocked state every 1000 milliseconds, and therefore toggles

- * the LED every 200 milliseconds.

+/******************************************************************************
+ * NOTE 1:  This project provides two demo applications.  A simple blinky
+ * style project, and a more comprehensive test and demo application.  The
+ * mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting in main.c is used to select
+ * between the two.  See the notes on using mainCREATE_SIMPLE_BLINKY_DEMO_ONLY
+ * in main.c.  This file implements the simply blinky style version.
+ *
+ * NOTE 2:  This file only contains the source code that is specific to the
+ * basic demo.  Generic functions, such FreeRTOS hook functions, and functions
+ * required to configure the hardware are defined in main.c.
+ ******************************************************************************
+ *
+ * main_blinky() creates one queue, and two tasks.  It then starts the
+ * scheduler.
+ *
+ * The Queue Send Task:
+ * The queue send task is implemented by the prvQueueSendTask() function in
+ * this file.  prvQueueSendTask() sits in a loop that causes it to repeatedly
+ * block for 1000 milliseconds, before sending the value 100 to the queue that
+ * was created within main_blinky().  Once the value is sent, the task loops
+ * back around to block for another 1000 milliseconds...and so on.
+ *
+ * The Queue Receive Task:
+ * The queue receive task is implemented by the prvQueueReceiveTask() function
+ * in this file.  prvQueueReceiveTask() sits in a loop where it repeatedly
+ * blocks on attempts to read data from the queue that was created within
+ * main_blinky().  When data is received, the task checks the value of the
+ * data, and if the value equals the expected 100, writes 'Blink' to the UART
+ * (the UART is used in place of the LED to allow easy execution in QEMU).  The
+ * 'block time' parameter passed to the queue receive function specifies that
+ * the task should be held in the Blocked state indefinitely to wait for data to
+ * be available on the queue.  The queue receive task will only leave the
+ * Blocked state when the queue send task writes to the queue.  As the queue
+ * send task writes to the queue every 1000 milliseconds, the queue receive
+ * task leaves the Blocked state every 1000 milliseconds, and therefore toggles
+ * the LED every 200 milliseconds.

- * standard demo application tasks, which provide no particular functionality,

- * but do provide a good example of how to use the FreeRTOS API.

- *

- * In addition to the standard demo tasks, the following tasks and tests are

- * defined and/or created within this file:

- *

- * "Reg test" tasks - These fill both the core registers with known values, then

- * check that each register maintains its expected value for the lifetime of the

- * task.  Each task uses a different set of values.  The reg test tasks execute

- * with a very low priority, so get preempted very frequently.  A register

- * containing an unexpected value is indicative of an error in the context

- * switching mechanism.

- *

- * "Check" task - The check executes every three seconds.  It checks that all

- * the standard demo tasks, and the register check tasks, are not only still

- * executing, but are executing without reporting any errors.  If the check task

- * discovers that a task has either stalled, or reported an error, then it

- * prints an error message to the UART, otherwise it prints "Pass.".

+/******************************************************************************
+ * NOTE 1:  This project provides two demo applications.  A simple blinky style
+ * project, and a more comprehensive test and demo application.  The
+ * mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting in main.c is used to select
+ * between the two.  See the notes on using mainCREATE_SIMPLE_BLINKY_DEMO_ONLY
+ * in main.c.  This file implements the comprehensive test and demo version.
+ *
+ * NOTE 2:  This file only contains the source code that is specific to the
+ * full demo.  Generic functions, such FreeRTOS hook functions, and functions
+ * required to configure the hardware, are defined in main.c.
+ *
+ ******************************************************************************
+ *
+ * main_full() creates all the demo application tasks and software timers, then
+ * starts the scheduler.  The web documentation provides more details of the
+ * standard demo application tasks, which provide no particular functionality,
+ * but do provide a good example of how to use the FreeRTOS API.
+ *
+ * In addition to the standard demo tasks, the following tasks and tests are
+ * defined and/or created within this file:
+ *
+ * "Reg test" tasks - These fill both the core registers with known values, then
+ * check that each register maintains its expected value for the lifetime of the
+ * task.  Each task uses a different set of values.  The reg test tasks execute
+ * with a very low priority, so get preempted very frequently.  A register
+ * containing an unexpected value is indicative of an error in the context
+ * switching mechanism.
+ *
+ * "Check" task - The check executes every three seconds.  It checks that all
+ * the standard demo tasks, and the register check tasks, are not only still
+ * executing, but are executing without reporting any errors.  If the check task
+ * discovers that a task has either stalled, or reported an error, then it
+ * prints an error message to the UART, otherwise it prints "Pass.".
