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