QUESTION
I 'm listening rs232Com using Portcom event-listener then generating propertychangelistener for interface controllers and everything works fine.
My new problem is that acquisitions for some sensors (anemometer) can terminate without any particular indication ( Pulse response ) and mostly dependent of bearings used.
The only solution i can see is that after an amount of time without anymore acquisition ( 2000ms ) i would like to end records to avoid recording data due to involuntary sensor handling .
At this point i can stop acquisitions unregistering controller of new message listener list using a button but i would like to do that automatically.
The point that miss me is to create a Timer that could launch a task after his delay timed out.This with a re-init function to feed him at each acquisition, barely the same way a watchdog works.
I started to search on web but i didn't find solutions and moreover which direction to go to
-Timer class
-Using a Thread / Runnable
-Schedule
-Modified watchdog
Thanks in advance

Answered 2022-Mar-10 at 14:01For this kind of problem, I often go with a custom thread that has a timer as attribute. The thread check its timer regularly and do something when it ends. And in my main I can add time to the timer attribute if I need to continue.
