* 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.
