wait ms sec with out daylight time problem and suppress jitter

[Benoit]

How tu use a good wai ms?? One solution is to use the Wait (ms) but it's result in a time jitter. We can use wait until next ms but the same problem will occured. Tick count give a realy bad result after aproximately 49 Days. The other solution sugested by NI give bad result with Daylight or any change in sustem time of the computer.

So I bring this little solution feel free to use it in your code it's a quite good VI. The jitter is about 60us. Not that bad.

Have a happy programming time...

Hi Benoit,

why do you use a password? Who should someone learn from it? Can you upload an example, which shows how to use the vi?

Thanks

Mike

[Benoit]

Here is an example on how to use it.

Hi Benoit,

Is the purpose of your post to share your code?  If so, then you may want to post it in the Developer's Network. 🙂

I was looking in the pass for a solution in this Forum. So i developed one and if any body is looking for a solution, it will be easier to find.

That's a good idea.

Thanks for sharing 🙂

It would be useful to provide a comparison between your VI and other solutions. Also, since you've password-protected the VI there's no way to tell whether you're using pure G or you're using system calls (which other solutions have done in the past). Obviously, if you are using specific system calls that would mean it's platform-specific.

Pure LabView.

How did you measure the jitter? As I indicated, a testing platform would be useful.

Note that this line of questioning is not intended to detract from the submission, but to make it more useful.

Here is another example. The jitter is platform and pc dependent of course. i have a dual core Computer with 2.0Ghz
