* Creates all the demo application tasks, then starts the scheduler.
* In addition to the standard demo tasks, the following tasks and tests are
* defined and/or created within this file:
*
* "Check" task - This only executes every five seconds but has the highest
* priority so is guaranteed to get processor time. Its main function is to
* check that all the standard demo tasks are still operational. The check
* task will write an error message to the console should an error be detected
* within any of the demo tasks. The check task also toggles the LED defined
* by mainCHECK_LED every 5 seconds while the system is error free, with the
* toggle rate increasing to every 500ms should an error occur.
*
* "Reg test" tasks - These fill the registers with known values, then check
* that each register still contains its expected value. Each task uses
* different values. The tasks run with very low priority so get preempted very
* frequently. A register containing an unexpected value is indicative of an
* error in the context switching mechanism.
*
* See the online documentation for this demo for more information on interrupt
* usage.
