timer problem

[Aquaphire]

Hello all,

I'm trying to add to my program the equivalent of a timestamp, except that it records the time elapsed from the start of the program...

like

 "press button" --> timer starts    writes: "0 seconds"

 "press button" --> timer records writes: "2 seconds"

etce tc...

I was thinking of subtracting 2 times... but I don't think it works. Any suggestions please?

thanks.

If you just want milliseconds, get the tick count at the start of the program (e.g. outside the main loop).

Inside the loop, you can now get the elapese time by using another tick count and subtracting the start value above.

Is it possible to set the tick count to 0 ?

Is it possible to set the tick count to 0 ?

In a way...  here's how to get the timer starting at 0.

Another question 😞

What IF (yes i know i'm being troublesome) I only wanted the timer to start the FIRST time I pressed the record button...? I can't really place it outside the loop because that wouldnt work...

[Will.D]

Well is your loop always running, or does it only run during "record"?

[Aquaphire]

Well, One loop is always running. the other one isnt.

Let me attach my VI.

Just do something like in the attached modification. (converted to LabVIEW 6.1). I hope it is clear.

Perfect! Many thanks 🙂
