This simple, yet powerful framework can be applied to virtually any application. In
the Main loop the subroutine called Critical_Task is executed through every
iteration of the loop, with the currently-selected task following.
circumstances the order of execution would be:
Critical_Task
Task0
Critical_Task
Task1
Critical_Task
Task2
Note that all task code is embedded in subroutines. This design allows a task to be
called from any point in the program – even from another task. Note that Task2
has the ability to check for an emergency condition and if that condition exists can
call Special_Task.
The key to using this framework is to break your program into small, lean tasks. By
doing this, your program will have the best responsiveness and the greatest amount
of flexibility.
