LabVIEW with Pasco's Science Workshop 750

I am trying to get LabVIEW 2012 to communicate with the Pasco Science Workshop 750 Interface.
I have downloaded the drivers
http://www.pasco.com/file_downloads/labview/SW750LabVIEW.zip
from Pasco's page
http://www.pasco.com/family/labview/index.cfm
I run into problems when I initialize any measurement. I remember using these a couple of years ago, probaby on a windows XP machine without any problems. Has anyone had similar problems and come up with a solution?
Thanks
Keith

This is the error I get when running the subroutine. I am not that familiar with the call library function workings.

How can I read pdf files from LabVIEW with different versions of Acrobat reader?

How can I read pdf files from LabVIEW with different versions of Acrobat reader?
I have made a LabVIEW program where I have possibility to read a PDF document. When I made this LabVIEW program it was Acrobat Reader 5.0.5 that was installed on the PC. Lather when the Acrobat Reader was upgraded to version 6.0, there was an error when VI tries to launch the LabVIEW program. And Later again when we upgraded to Acrobat Reader 7.0.5 I must again do some changes and rebuild the EXE files again
It isn't so very big job to do the changes in one single LabVIEW program, but we have built a lot of LabVIEW programs so this take time to due changes every time vi update Acrobat Reader. (We have build EXE files.)
The job is to right click the ActiveX container and Click "Insert ActiveX Object", then I can brows the computer for the new version of acrobat Reader. After this I must rebuild all the "methods" in the Activex call to make the VI executable again.
Is there a way to build LabVIEW program so I don't have to do this job every time we update Acrobat Reader?
This LabVIEW program is written in LabVIEW 6.1, but I se the problem is the same in LabVIEW 8.2.

hi there
try the vi
..vi.lib\platform\browser.llb\Open Acrobat Document.vi
it uses DDE or the command line to run an external application (e.g. Adobe Acrobat)

You can ONLY use the itunes store of your country of residence ( proven by the billing address on your credit card) AND ONLY while you are physically located inside the borders of that country.
You would have to live in the U.S and physically be located in the U.S in order ot use the U.S tunes store. The same is true for each countrys itunes store.

How to create a dll in LabVIEW with a 2D array

I'm attempting to create a dll in LabVIEW with the following parameters from Test DLL.vi:
Inputs:
IN1 - Word
Buffer - 2D array of Unsigned Byte
Output:
OUT1 - Unsigned Byte
The prototype is constructed as follows in the Build Specifications of the Project:
uint8_t TestDLL(int16_t IN1, TD1Hdl *Buffer)
The dll builds successfully but when I attempt to use it in another VI (using the Call Library Function block) the prototype appears but it does not look like what was defined from the Build Specifications. Instead it looks like the following:
void TestDll(void );
I attached some screen shots of all the settings as described above.

I have found a person who has a driver software to connect Labview with PCI card. But he says that i need to download a freeware software to configure the PCI card. But you have mentioned that freeware is for GPIB boards. Is it correct ??

I have found a person who has a driver software to connect Labview with a general PCI card. But he says that i need to download a freeware software from NI website to configure the PCI card. But you have mentioned that freeware is for GPIB boards. Is it correct ?? Is there any other way out ??

I would ask the person who told you about the freeware software to help you find exactly where it is. I am not aware of any freeware software for configuring motion PCI cards but maybe the person you know might be able to help you locate it.

How to use labview with the handyboard

Hi,
how to use labview with the handyboard
Thx...

I'm assuming you're talking about this, since you didn't provide a link for those of us who don't know what you're talking about.
As the other poster said, you didn't say how you want to use LabVIEW with it. If you want to write LabVIEW programs than run on the microprocessor, then you're out of luck. If you want LabVIEW to interact with it, then you've got a couple of options, SPI probably being the best, but it also has DI and AI that you could use to communicate with it - the DI's could be used as a parallel interface.

Sir
We were able to solve that problem...but now could you advice as to which DC power supply we should use (preferably avalable in India) so that it can be controlled by Labview (through a gpib/rs232/any other port) to give a square wave of desired frequency/other parameters.

Link labview with other software which can do hydraulic simulation such as Nanas Fluent.

   Hi all:
          I currently want to exchange data between labview with Ansys fluent. That is: sending flow boundary condition and initial condition from labview to hydraulic simulation software (ansys fluent), and get simulation result back to labview from that software.
         I didn't find any modules online to link labview and fluent together. (There are others such as Labview Solidworks module)
         Is any one know how to link labview to any software which can do hydraulic simulation?
         Thank you very much. :-)
-Bowen

Do you know of any other programs that exchange data with Ansys? If so how do they do it? ActiveX is a common way for communicating between LabVIEW and other programs, is this an option?

Diffing Files in LabVIEW with Perforce?

I've read the sections of articles about doing a graphical difference in LabVIEW with Perforce here: http://zone.ni.com/devzone/cda/tut/p/id/4631#toc4 and here: http://decibel.ni.com/content/docs/DOC-1681#Graphical_Differencing, but I still can't get it to work!
When I right click on a VI from the Project Explorer that is checked out and select Show Differences... Perforce complains that it doesn't know how to do the diff on the files. I assume this is because I haven't told Perforce about the LabVIEW Diff features or the .vi file extension types. How do I this? Is there an article I missed somewhere that describes this step by step?
Edit: I forgot to mention, how do I use the Compare VIs tool in Tools -> Compare -> Compare VIs? When I do this it bring up a dialog in which the first field is the VI I have open. The second field is blank, and that is the VI that I would compare the VI open to. However, since I am using Perforce, the previous file revision are in Perforce. How do I tell this dialog to compare it to a file that is in Perforce?
Thanks in advance!

In the LabVIEW help there's a LVCompare.exe topic; under that, look at "configuring source control with." Following the directions there will allow you to show differences directly from Perforce. However, within LabVIEW, this shouldn't be necessary -at least, it's always worked "right out of the box" for me with no further configuration. Which of the two LabVIEW Perforce clients are you using? You may need to use the command line version in order for differencing to work properly.
Compare VIs does not work the way you seem to expect for VIs in source control. It simply compares any two VIs loaded in memory. To compare with the latest version from Perforce, use Tools -> Source Control -> Show Differences. If you want to compare something other than your current version versus the most recent revision in Perforce, you'll need to execute the diff from within Perforce.

How do I invert meter in labview with needle pointing downwards

Hi,
I need to invert meter in labview with needle pointing downwards .
Can somebody guide me?

Try rotating the scale. The needle will follow the scale. This should help.

Getting errors and LabView with ARM project won't compile

Hello there, I am currently turning to make a project run on a STM32f103C8 chip using LabView with ARM. I am currently trying to compile a ARM project but I have no been successful.
I have tried using the STM32F10x template uploaded by Joshua, and it tries to compile. At first I was getting the "stm32f10x_tim1.c" file missing error, but that was solved by downloading the file from firmware v1 and adding it to the includes folder. but now i am getting a new error saying "profile_timer.h" is missing.
I am using:
Windows 7
LabView 2010 evaluation
NI ARM module
and I am trying to compile a empty project
Here is the error code message, any hepl will be useful, thanks:

blank projects using other included boards seem to compile fine
and i have added a mock "profile_timer" to the keil library (just as a quick fix) and it seems to have stopped a lot of the errors, however i am still getting a few
these seem to be:

i'll see if i can find a file for the ccgfilesupportpriv.h but the error directive worries me a bit

LabVIEW with version control

Hi,
      I am using LabVIEW with version control and only want to check out the VI which I need to modify. If I changed a subVI all the VIs directly or indrectly called this VI got recompiled and in order to save them I need to check out all the VIs are affected. If I only check out the file I need to modify and ignore other recompiled VIs the problem is if I use typedef ENUM and I still want the automatically updated VI got saved. Does anybody run into this problem?
    Thanks for help!
    Regards,
    Tom
Solved!
Go to Solution.

Yes, it can be a problem since LabVIEW stores the source and compiled code in the same file. There is an option to separate source from compiled code that addresses this problem. I have never used it and don't know if it causes any other problems.

Interface Labview with custom board

Hello, I want to use Labview with a board I designed. To be brief my board has an Altera FPGA, some memory, and a fiber-optic transceiver. I want to develop a Labview program to display the data I'm receiving from my fiber-optic transceiver. I want to know if this is possible to have Labview interface with a non-National Instruments board? What do I need in order for Labview to work with my board. In my previous design I had the received data written directly to the computer's main memory. Could I do something like that, just tell Labview where in memory to get the data to be displayed?
thanks,
joe

Absolutely. I'm doing that right now with VISA. Look at the posting here. There are some links there in how to procede.
