Reg Event Callback

Evgeni — Tue, 11 Jul 2006 09:05:56 GMT

I need count number of frames that occur.To count frames I use Reg Event Callback.To activate this func properly I need connect Event callback to VI.ref.My question is how I nedd modify Event callback to get the number of events.

You need to give quite some more information. What you tell us here is like if I would ask you to help me repair my car. No model, no nothing and no way for you to know what is defect. I'm sure you would have a hell of a problem to even know if you could help me.

hi there

do you mean something like this (see attachment)? there are lots of ways to count the events, i show you my favorite one (uses a construct called "FGV" aka "functional global variable" aka "LV2 global")
