- * Creates all the application tasks, then starts the scheduler.

- * A task is created called "uIP". This executes the uIP stack and small
- * WEB server sample. All the other tasks are from the set of standard
- * demo tasks. The WEB documentation provides more details of the standard
- * demo application tasks.
- *
- * Main.c also creates a task called "Check". 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.
- * Each standard demo task maintains 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 yellow LED.
- * Should any task contain an error at any time the LED toggle rate will change
- * from 3 seconds to 500ms.
