 * Creates all the demo application tasks, then starts the scheduler.  The WEB
56
 * documentation provides more details of the demo application tasks.
57
 *
58
 * In addition to the standard demo tasks, the follow demo specific tasks are
59
 * create:
60
 *
61
 * The "Check" task.  This only executes every three seconds but has the highest
62
 * priority so is guaranteed to get processor time.  Its main function is to
63
 * check that all the other tasks are still operational.  Most tasks maintain
64
 * a unique count that is incremented each time the task successfully completes
65
 * its function.  Should any error occur within such a task the count is
66
 * permanently halted.  The check task inspects the count of each task to ensure
67
 * it has changed since the last time the check task executed.  If all the count
68
 * variables have changed all the tasks are still executing error free, and the
69
 * check task toggles the onboard LED.  Should any task contain an error at any time
70
 * the LED toggle rate will change from 3 seconds to 500ms.
71
 *
72
 * The "Register Check" tasks.  These tasks fill the CPU registers with known
73
 * values, then check that each register still contains the expected value, the
74
 * discovery of an unexpected value being indicative of an error in the RTOS
75
 * context switch mechanism.  The register check tasks operate at low priority
76
 * so are switched in and out frequently.
