44 * Creates all the demo application tasks, then starts the scheduler. The WEB
\r
45 * documentation provides more details of the demo application tasks.
\r
47 * In addition to the standard demo tasks, the follow demo specific tasks are
\r
50 * The "Check" task. This only executes every three seconds but has the highest
\r
51 * priority so is guaranteed to get processor time. Its main function is to
\r
52 * check that all the other tasks are still operational. Most tasks maintain
\r
53 * a unique count that is incremented each time the task successfully completes
\r
54 * its function. Should any error occur within such a task the count is
\r
55 * permanently halted. The check task inspects the count of each task to ensure
\r
56 * it has changed since the last time the check task executed. If all the count
\r
57 * variables have changed all the tasks are still executing error free, and the
\r
58 * check task toggles the onboard LED. Should any task contain an error at any time
\r
59 * the LED toggle rate will change from 3 seconds to 500ms.
