Voltage logging

[naarchib]

Hello all,

I was wondering if anyone knows how I can create a voltage logger in Labview using the NI myDAQ. What I want the logger to do is measure the voltage say every 30 seconds or minute while inputing the data onto a graph so that I can display it. 

If anyone one has any ideas then please tell me where I can get started.

Thank You!

Hi naarchib,

There are resources on websites guide you on how to use myDAQ with LabVIEW.

I found one youtube video that might be useful for you

For timing, you might want to look at the link below to study more on how you can play around with timing function in LabVIEW

Thank You! I will take a look at it.

EDIT:

Oh but I don't see the link to the youtube video?

Sorry copy the wrong link

below is the link

LabVIEW part should be around 2 mins in the video

I'm pretty sure you can use DAQmx with the myDAQ.  Look through the examples in LabVIEW (Help->Find Examples) and do a search for Voltage Analog Input.  There should be a good example in there that will get you mostly to where you want to be.

You can but not all of the myDAQ functionality can be used through DAQmx alone.  After installing the myDAQ software a special palette appears with myDAQ express VIs for doing stuff.
