Oscilloscope development with NI USB 6001

[Milhojas]

Hello,

Im planning to develop a virtual oscillpocope using Labwindows/CVI for my university project. I was wondering if its necesary to use CVI Real Time or not? I heavent much experience with CVI and this will be my first project, so If you guys have any tips it would be great. And also is there maybe any similar project developed before that I could have a look? 

Thanks

Hello,

You'll need Real Time modules only if you want to develop Real Time functionnalities, on a real time OS.

Start by looking for examples in labWindows/CVI and online.

Thank you,

So as I understand I dont need the Real-time module.

But my main consern is that when I use NI-DAQmx for samling should I use continous mode or N samples?

Daq cards do have deep buffers. You just fetch them at predefined intervals . Use the assync timer callback function as that it is accurate to couple of ms resolution.

Thank you,

Thats what I did to developt my oscilloscope. Now I only have to present it to my teacher. I hope that goes well.
