how to do a voltage ramp

[jpnavarini]

Hello All,

              I'm a beginner on LabView and have written a program to generate the following ramp shown below. From the graph it appears to be working, however when I plug in a scope or voltmeter into the board, I see no output. Why?

Riclambo -

You won't be able to see anything in the scope because you are executing the program once.

For you to be able to see something when you plug a voltimeter on your board you should place a while loop.

Since you are a beginner to LabVIEW I would recomend using the Express VIs (in this case a DAQ assistant output). That way you can configure your acquisition to output data on a especific channel of the board you are using.  Remember to select continuous samples or else you won't be able to see anything when you connect or scope or voltimeter.

If you want to leave the function with the same apperance as the one you sent, right click on the Express VI and select "generate DAQmx Code"

Hope this helps

Best Regards
