Alternative to periodic trigger

[Basilisvirus]

I want to know how can I make a periodic trigger without using the "periodic trigger" from the OpenGLibrary if labview, on windows 7 machine with labview 8.5. I want to trigger a case structure every 500ms. 

As a note, I am able to do this using my Labview 2013 version on windows 10 by downloading the OpenGL library, but at college they are more limited with their Versio 8.5 Labview and I would like to use the default libraries.

I also attach the .vi I managed to make on my 2013 Version Labview.

Hi Basilis,

just look inside the OpenG function to learn how to recreate it with LabVIEW8.5…

Thanks.

This is it, in case anyone needs it:

Note that there's a subtle "off-by-one" error in the openG function.  Change the ">" greater-than comparison to a ">=" greater-than-or-equal to fix it.  I'm pretty sure I tried to report it into the openG dev forum many years ago, but never followed up further.
