******************************************************************************
*
* main_full() creates all the demo application tasks and a software timer, 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.
* main_full() creates all the demo application tasks and two 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 initially 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 it
* changes its own execution period from the initial three seconds, to just
* 200ms. The check software timer callback function also toggles the green
* LED each time it is called. This provides a visual indication of the system
* status: If the green LED toggles every three seconds, then no issues have
* been discovered. If the green LED toggles every 200ms, then an issue has
* been discovered with at least one task.
* "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.
