*
|

* 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.
