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