Include example for one-off task

[skorokithakis]

I have a relay I need to turn on and then off after N seconds. I see the LED example, but it defines multiple tasks, and understanding the flow becomes a bit complicated. Is there an example where a single, one-off task is scheduled for N seconds, with an "on" and an "off" handler? That would be very much appreciated.

Easy. 

Define a task:

    Scheduler ts;
    Task tRelay (relayOnTime * TASK_SECOND, 2, &callback, &ts);
    ...
    void callback () { 
      if ( tRelay.isFirstIteration() ) {  
        turnRelayOn();  
        return;
      }
      turnRelayOff();
    }

Initiate the task with this:

tRelay.enableDelayed( initial delay );

That's it.  Hope this helps.

Thank you! Also, is there a way to cancel the task that's already scheduled? Sometimes I have to turn the relay off in an emergency and would like the task (or all tasks) to cancel at that point.

tRelay.disable().There is a Wiki, you know, that you need to read :)On Jul 12, 2020 3:37 PM, Stavros Korokithakis notifications@github.com wrote: Thank you!

I searched for "cancel" and "stop" and didn't find this, sorry 😟
