Which "difficulties" do you encounter?

I just added a FOR loop and a BuildWaveform function… (And replaced the "bytes to read" with a large constant value.)

Could you please share the VI file with me?

No, I didn't save the VI…

Btw. you should replace the i/o tunnels (VISA reference, error wire) of the FOR loop by shift registers. I forgot that step…

how can i use this thing

This is what I’m getting right now. What’s the problem here?

I don't see a problem apart from that "0" wired to dt of the waveform…

The FOR loop will take some time to collect 200 samples (at 10Hz it will need ~20s)!

By debugging you can learn how to use it!

What about a waveform graph to show the waveform feed into the analysis function?

deer gredw
i always got this eror and i dont know why?

[llimpaull]

I’m getting a plot in one graph, but nothing is showing in the other one.

Based on what is explained in this link, it seems that we cannot place this VI inside a loop.
So my question is: how can I acquire the full dataset in LabVIEW only once, and then send the complete waveform to this analysis VI so that it can calculate the blood pressure in a single step?

Hey

I have problem with this

That’s exactly what I did, but the analyzer did not recognize my data. I also tried using the simulation, and it worked, but I don’t understand why the analyzer cannot process my data. Could it be a timing issue?
