How can I create a knob that I can turn multiple times?

Hello,
I'd like to create a knob that I can turn multiple times.
It shoud be possible to set the increment value per revolution.
Further it would be nice if it's possible to select the datatype Int, DOUBLE.....

I did that programmatically a while back and I've gone and dug it up. So here is a knob with attached mini-program that shows how I did it (okay I updated it to use an event structure - something I didn't have in 6.0). See if this is the kind of thing that you're looking for. I'm sure there's more elegant ways of doing this.

Here is a simple example where you can set the increment/revolution.

(This example does DBL output. You would need to create seperate code depending on data type).

Hello Robert,
Thank you for your nice example.
But you have to modify it because it doesn't work always in the right way.
If you turn your knob 1 time you have got values (from the knob) between 0 and 10'000. In the event structure you then count up and down. But if you have values (from the knob) lower than 200 or bigger than 9800 then the knob always counts -1 he don't care about the rotating sense...

Hello to you all,

I was searching for a multiturn dial which looked like a multiturn potmeter, this forum had inspired me to make one.

I hope someone kan use this for a project, please let me know if you like it and/or have some improvements.

Those examples work fine in ordinary Labview, but unfortunately LabView realtime cannot handle event structures. anybody got a version without event structures?

Here's my stab at it.  Two versions: 1) A knob in a regular VI, 2) An XControl.

Brilliant but if possible could you please post as Labview 14 or earlier as I don't have 16 yet!

 

Thanks
