Hi Guenther,

strange... I think you should try contacting Bryan Tyler of NI (lycangeek) He is the .net master of them!

Ton

Maybe the dll is not registered on the target?

Try running regsrv32.exe with the dll name as parameter

Ton

Nice implementation. Were you aware that Jim Kring had already done something similar?

Hi Mike,

No didn't know, it looks like you had a different approach. And the old OpenG content is hard to get...

Only one question when I want to probe a non-variant data type I get this error:

Has the probe engine changed?

Sounds like an update with a resizable window is in order.

Here you go! And you used another screenshot (mine was too big I assume?)?

Have fun

Ton

Ray,

that is good news!!

Now I have to talk to my boss, that he will purchase one (LVPDA, PDA, CompactDAQ)

File Name: VariantProbe

File Submitter: tcplomp

File Submitted: 4 Dec 2006

File Updated: 24 august 2012

File Category: Custom Probes

This Custrom probe is useful for browsing the contents of a variant.

It will try to parse all the fields in the variant (notify me if you have a fail).

It will track the history of the variant and allow you to pause on a change.

It will present the data in a tree structure, allowing you to browse through the history.

Be warned, the tree structure is great for viewing, but tracking a lot of history (>50 or so) will slow down the update of the tree.

Version History:

• 2.4: Immediate updating after changing of attributes
  Rebuild in LabVIEW 2011
  
• 2.3: Fixed a bug that caused attributes not to be traversed on certain data-types
  
• 2.2: Fixed a relinking bug
  
• 2.1: Fixes a bug where unnamed cluster elements where used (http://lavag.org/topic/10269-discuss-variantprobe/page__view__findpost__p__67677)
  
• 2.0: Added an XControl
  Show XControl in palette (under user.lib controls)
  Add coloring
  Add 'user permissions' on XControl
  Add Reset on XControl
  Add optionally traversing attributes on XControl
  Add optionally colorizing on XControl
  Add optionally resetting on XControl
  
• 1.2.0: Upgraded to LabVIEW 8.5 to use Inheritance
  Support for Waveforms, timestamps and dynamic datatypes (thanks to Osvaldo)
  Added probe for an array of Variants
  Distributed as one .llb and added OGP installer
  If a Variant hasn't changed it's not decomposed (optimization)
  
• 1.1.0: Support for attributes of variants
  
• 1.0.1: Controls placed on a seperate pane
  Resize tree to upper pane
  Hide unused columns
  Limited maximum history length (default 10)
  Window resizable
  
• 1.0.0: Initial release of the code.
  

Uses the following OpenG packages:

oglib_comparison-2.0-1

oglib_lvdata-2.7-1

oglib_file-2.7-1

oglib_string-2.5-1

oglib_error-2.3-1

To get these OpenG packages use VIPM

If I were you I would check that daqmx for PDA supports these DAQ's. I am not sure that they do.

Nicholas,

why do you mix two timing types?

You have a timed sequence, which is the correct item for your application. And you use the wait function based on the OS time.

I suggest you use the timing of the timed sequence (I have never used it, but think this is what you need):

In the first frame, I read the start time of the frame, add the wait time and then set the start time of the next frame. You should do this for the third frame as well

I think you can limit your sequence to two frames, one where you make the output high, and one where you make the output low. The timing of the frame will set the speed correct.

Ton

Oh, OK. So I guess I should just send an email to NI and ask for a Licence? Great, I'll do that. Gee, I didn't think it would be so easy.

Or as my friends say when we see a good looking girl in a bar:

'No, do you have a smack in the face is what you can get'

(which is similar to a saying: 'No, do you have, yes is what you can get' basically meaning that if you don't ask you will never get)

Hi all,

any body had a LABVIEW PDF ?? i want any source related to electrical and electronics engineering plz help me I am requestin g some books but I didnot get them so far

Hello Alnaimi,

you should search the LabVIEW bookshelf, if you have LV 7. In 8 it is removed. But the LabVIEW help covers most everything there is to know about LV. Now if you want to digg deeper consider a LV basics course, if I'm right you can purchase those books without a course.

But why do you connect LV and electrical/electronics engineering?

LV is (almost) a full blown IDE for a programming language, and the block diagram might on the first hand look like a electrical print but there is no connection

Now for starter questions (like your previous about the amplifier), the NI forums are better.

Search on the LV learning center for the knowledge you need.

Ton

(oke the turned me over and the coffee is OK)

Ok, let's start the rumour mill...

What @#$%& scripting licence?

The one you won't get!

but totally OT, how do you spell license/licence????

Or is it another english vs. american thing like color/colour?

Ton

Nick Storton gave an explanation at NI.com.

It is something natural in the array and function.

Ton

Don,

I think your wrong. You can build an installer for the dll? or not?

well the 8.2 runtime is here:

LV 8.2 runtime

I think the smaller one is sufficient for dlls (lvruntimeeng.exe)

Ton

Hello Frontiergo,

good afternoon and welcome!

Hopefully you know how to , it will help you

However when in doubt (and polite) ask.

Ton

What do you need, your previous question gave you a valid answer.

Please, be more specific and show what you have already!

Ton

hi all ,

thnx for reading my topic in this great forum , actuallly its my main source of learning LABVIEW....

I have question where can I find amplifier in LABVIEW??????????????????

What do you need, your previous question gave you a valid answer.

Please, be more specific and show what you have already!

Ton

No I don't have an idea.

We have no issues in using the same functions.

Ton

Maybe a totally other idea might be an XControl?

This gets notified an exe start running and you can register for the panel resize event.

And via property nodes you can add all the controls with their resize data.

Ton

So How many ways are their to Rome?

Bring it on!

Amstel please

Ton

Now where is that one thread that Chris didn't reply to

:laugh:

Congrats!

Ton

Hi John,

it sounds like you have an empty (void) array. Right click on the FP-array and add a numeric indicator, this will provide a datatype for the array, and LV can put things in it.

Ton

Or you could use the OpenG periodic trigger

:worship: :worship:

Didn't know that I had so much in common with LV.

Is this the reason that LV 8 introduced itself as seperate Application Instances, so they can speak Esperanto with each other?

ne VIs kun erros

Now comes the Q:

what INI-key starts this mode?

Second (philosophical) Q:

Does LV sees itself as male, female or neutor?

Ton

PS Aristos, you made the sun come throught the clouds

Hi Gianmarco,

A framing error is mostly meaning there is something wrong with the serial settings.

Have you tried other settings?

A good thing to start with is MAX, if you succeed to communicate with the device from there you will get it in LV right.

Second pass the VISA-resource from one subvi into the next, I'm not sure if it is usefull but better safe than sorry.

You should rise your timeout, in MATLAB you use 10 seconds and here just 1.

Ton

PS don't quote a full post in a reply

Chris,

here's to you: :beer: :beer: :beer:

If you come to the netherlands, stop by and let's drink another :beer: :beer:

Thanks for the CR work, I can understand it is very much work! :thumbup:

Ton

Hi gianmarco,

I see some issues in your code, you tell VISA to wait for a termination character (the T-boolean), and specify this byte as 0x00 (a null-byte) but your specs say it should be a CR (0x0D).

You try to read 1024 bytes thought you'll only get 14 bytes per reading.

You specify XonXoff as flow control this doesn't show up in your specs

Why did you modify the VISA configurator?

Hopefully this code can help you:
