Basic Read/Record Voltage

[Mr. Mu]

Hi all,

Sorry, I am quite new to Labview, and I was wondering if anyone could help me figure out what is wrong with my VI.  I am trying to read in a simple voltage using a USB 6008 and record the data.  Any input would be greatly appreciated.

Hi Mu,

have you read that error message, when trying to start the VI? It's pretty straight-forward...

Otherwise look here!

Thank you very much Gerd! Sorry for the delayed reply but I had to put this project on hold for a bit.  I just had a quick follow up question.  Is there any way to add a start button to the while loop? I was looking around your link, but I could only find references to stopping a while loop.  I wanted to be able to run the program multiple times without having to restart it.

Hi Mu,

"run the program multiple times without having to restart it."

Something like putting the existing VI into another while loop?

Hello,

It sounds like you'd need to add an event structure.  You can use an "event" such as a button push to trigger a part of your code to execute.  Here's a link to some event structure basics.

I hope this helps!
