From the course: Data Acquisition with LabVIEW
Continuous analog input
- [Instructor] Finite analog input works well when you know exactly how many samples you'll need to acquire ahead of time. But if your acquisition task may need to run for a long unknown duration, then you'll need to configure it for continuous acquisition. And that requires a bit more work than simply changing the sample mode input from finite samples to continuous samples. Though I will need to do that as part of that process so I'll go ahead and make that change now. If I try running the VI now, I don't get any output. In order to perform a continuous acquisition I'll need to continuously read data from the acquisition buffer. And I'll do that by surrounding the read VI with a while loop. I'll need to make room for that in my code by moving around a few Vis. I'll add a while loop from the functions palette structures menu and wrap that around the read VI. I'll right-click on the stop terminal, create control to…
