LabVIEW with Pasco's Science Workshop 750

[hekdude]

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

Hi hekdude,

My name is Humphrey and I am an Applications Engineer at National Instruments. Could you give some more details about the problems that you are running into? Are you getting any errors?

Regards,

the initialize functions return an error of -1.

Are you getting the error that GetRegistry failed? It sounds like there is a file missing but it looks like it should be provided by PASCO.

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

I see that -1 error as well but I also get a "GetRegistry failed RegOpenKeyEx: Software\PASCO Scientific\DataStudio\Plugins The system cannot find the file specified." as soon as I try to open any of the examples. Do you get that error as well?

The Call Library Function node is used to call the DLL provided in the code. A -1 error usually refers to invalid input parameters but it looks like this error is showing up even before you run any code.

Thanks for your help.

I get the -1 error as well.  2 years ago, on a windows xp machine, I run the same program and it worked. It has been quite frusterating.

Unfortunately, since these drivers were not written by National Instruments, I am unable to tell you which files are missing. From the message that I was seeing, there is a file missing in the Plugins folder. I do not know if you are getting this message as well when you open up any of the examples. Do you remember if you downloaded or installed any other files or software from PASCO when you were still using your XP machine?

Thanks for all your help.
