Is there some software that lets me get just the voltage data in real-time?

[johndoe19]

I'm currently using a USB-6341 and I need to use the data from the DAQ as voltages. I need to be able to send the data in real-time to a tool I'm using.

Is there a way to do this? Or has anyone made some code that does this for me? (Noob when it comes to coding....). 

Similar to how the test panels in NIDAQmx, but with just the voltages, as and when it changes...

What language are you using?  What is this tool that you are using?

[johndoe19]

Essentially, C++. I don't really know what the tool is (work stuff; don't know what it is.) 

But the ideal case would be to output the voltages in real-time to the console. (Just to give it a bit of direction...)

And LabView is not an option for us...

There are examples for c++ that come with the installation of DAQmx. Try starting with those and post back with a specific question. Your comment about real time is a bit confusing. Do you intend to use an actual real time os or just want so many samples in a specific time? What sort of time period are you talking about? From the product page, you can see the sample rate.

I looked at the examples. They actually are pretty useful. And sorry if I confused you. I wasn't quite sure what I needed just then either. But I do now.

So the data logging into a .tdms file was kinda what I was looking for. What I need now, is to try and read the .tdms file using Visual Studio, while logging data into it. Could you tell me if that's possible, and if it is, how would I go about it?

Thanks!

I thought tdms was NI specific of maybe even LabVIEW specific. just log to a csv file and bring into excel when you are done.

Look into measurement studio support for c#. I don't miss cpp at all. Do you really need to stay there for this project? Utilize your cpp knowledge in c# and drop 500 on measurement studio for the controls and hardware control. It's well worth the money.

Unfortunately, I do have to stick with cpp. But never mind. I managed to work it out last night. I'm not going to use a tdms file. Might as well, stream the data directly. Thanks again!
