Software Recommendations for Displaying Realtime Data

scottiebabe

I wanted to put together a quick demo for an upcoming Roadtest. I used a software application called DAQFactory (https://www.azeotech.com/j/index.php ), mainly because it is simple to use and supports the old labjack U12.

After I tidy up the wiring, I can take photo/video of the DUT and live measurement data in the same frame. I have seen other members use a picture-in-picture live view of the DUT, which I think is pretty snazzy! Sometime I will try that too.

 

Is the new Free Edition of Labview worth trying out?

 

Are there other drag and drop measurement applications you think highly of?

  • I did end up downloading the free Labview Community Edition. It worked right out of the box as you would expect from a NI product. I was able to run some of the old labjack Labview demos too.

    I haven't used Labview in a very long time, I'm not sure what's changed. The sample labjack Labview VI's are exactly like what I remember Labview to be.

    For me personally, graphical programing is 10 times harder than just writing a Matlab/Python script.

     

    Hopefully, there are some simpler and cleaner examples with this Labview release.

    Assuming you know the serial or COM port protocol, why not use Python? There's plenty of GUI libraries about, e.g. https://pyscada.readthedocs.io/en/master/

     

    Alternatively look at https://processing.org/

    This is also a very versatile programming language.

    Thank you for the recommendations. Processing looks like a really neat and capable graphics language/environment I will give that a try. My only hesitance to using Python is I didn't want to have to program the physical layout. If I was doing I permanent installation I think I would try python and QT5:

    My interest in realtime data was as demonstration tool. I wanted to be able to display and annotate measurement data in a meaningful way in just a few minutes.

     

    I have never herd of processing, it looks like it will be fun to experiment with!
