 /******************************************************************************
  * 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:
  *
  * "Check" timer - The check software timer period is set to three seconds.
  * The callback function associated with the check software timer checks that
  * all the standard demo tasks are not only still executing, but are executing
  * without reporting any errors.  If the check software timer discovers that a
  * task has either stalled, or reported an error, then the error is logged and
  * the check software timer toggles the red LEDs.  If an error has never been
  * latched, the check software timer toggles the green LEDs.  Therefore, if the
  * system is executing correctly, the green LEDs will toggle every three
  * seconds, and if an error has ever been detected, the red LEDs will toggle
  * every three seconds.
  *
  * "Reg test" tasks - These fill both the core and floating point registers
  * with known values, then check that each register maintains its expected
  * value for the lifetime of the tasks.  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.
  *
  * "LED" software timer - The callback function associated with the LED
  * software time maintains a pattern of spinning white LEDs.
  *
  * See the documentation page for this demo on the FreeRTOS.org web site for
  * full information, including hardware setup requirements.
