 * Creates all the demo application tasks, then starts the scheduler.
56
 * In addition to the standard demo tasks, the following tasks and tests are
57
 * defined and/or created within this file:
58
 *
59
 * "Check" task -  This only executes every five seconds but has the highest
60
 * priority so is guaranteed to get processor time.  Its main function is to
61
 * check that all the standard demo tasks are still operational.  The check
62
 * task will write an error message to the console should an error be detected
63
 * within any of the demo tasks.  The check task also toggles the LED defined
64
 * by mainCHECK_LED every 5 seconds while the system is error free, with the
65
 * toggle rate increasing to every 500ms should an error occur.
66
 *
67
 * "Reg test" tasks - These fill the registers with known values, then check
68
 * that each register still contains its expected value.  Each task uses
69
 * different values.  The tasks run with very low priority so get preempted very
70
 * frequently.  A register containing an unexpected value is indicative of an
71
 * error in the context switching mechanism.
72
 *
73
 * See the online documentation for this demo for more information on interrupt
74
 * usage.
