Hi !

I've been working on my code with some nice progress. Took me probably 100x longer than for someone, who is an actual programmer, but in some way I think LabVIEW can be exactly this: programming for non-programmer

In the pic below, you can see a cluster merging most of my results/ readings together. It is then passed on to the next sequence where it is finally written to disk (marked green indicator)

I tried to add the readings from the lower left to this cluster (marked green) to it, so that everything would be written to disc together. I clustered the additional arrays and wanted to simply add it to the existing cluster. Somehow it doesn't recognise the arrays ??? Do I have to adjust the inputs on the "write to disc"-function ?

But … I can't get it to work. .. :headbang:

Could someone advise me why?

Regards,

Ivan

cool thanks

!!!

Hi !

just discovered the openG site. To opwn/use those vi's one needs the vi-manager. Does the new version of vi-manager work on my 7.1 LabVIEW ?

As I'am still looking for a appropiate filter for my 1D array ...

Thanks

Ivan

Thanks for the input !

Below the result with a medianfilter (right) compared to the curve hoe it should look like ...

the curve doesn't look too bad, but I can't apply low pass somehow, as the data was already filtered through low pass 5Hz, 2 oder Butterworth (tried with express vi "filter")

I just need a god da... curve fit or whatever too smooth it ... :headbang:

P.S. Am from Cape Town / South Africa = someone from the same city

Hi everyone !

Once again congrats for this forum. For someone like me (coming from a totally different background) it is a great opportunity to learn more about LabVIEW. :thumbup:

I sorted my shift register issue out.

On the pic below you can see two waveform probes. I would need an appropriate filter to get rid of the "noise" in the right one to get it to similar shape as the left one. I am using "7.1 full" version and put in the filter express. However rectangular smoothing seems to be insufficient and curve fit is too hectic on the original data. :thumbdown:

I red about point to point filter and array filter maybe an array filter would be better

Could someone help out

Ivan

@ jcarmody

hi !

It seems to work fine BIG THANK YOU

How can I configure the shift register to get rid of the initial value. Know you mentioned it in your post, but don't know how to actually do this

Ivan

@ jcarmody

thanks for your reply !!!!

will try to make this change

and ... no worries word.doc is clean next time I'll insert pic as png

cheers,

Hi everyone!

I am asking for some advice. Think my problem is rather simple, but so is my programming knowledge …

I have an array of velocity samples and all

I want to do is to build a new array containing the values of delta velocity between consecutive data points.

Could someone explain how to do this?

(for loop? indexing array? … )

I attached a screen shot of the sequence with some explanations.

Hi to everyone on this awesome forum.

I am a sports scientist using LabVIEW for data acquisition and analysis of kinetics & kinematics in sporting movements.

So, I never had any training for programming or engineering. The code for my equipment was initially written by a NI-guy. I just try to adjust the code here and there… and I am getting used to the “broken arrow” without freaking out, hehehe

Regards,

Ivan
