NOTE:
I discuss this based on a reasonable compact URTOS that will fit a '51 NOT a full fledget large OD for a powerful processor. How about the Keil RTX51? If you disable an interrupt it will happen when you re-enable it (except level ints) Nope, only if the event has already happened. If not it will happen when the event occurs, not at a time you choose Interrupt priority selects which interrupt (event) is responded to, not when.
Indeed, it select that you want to handle it when the external event happens. So as I said not at a time you choose but one chosen by the event. With a time triggered RTOS you choose when external events are are handled when you define when the task that will handle them runs.
Nope It happens when the scheduler get around to letting you do it. And in a time triggered RTOS the scheduler is what is run every tick and it runs your task if you have chosen to run at that tick. Ian |
