matlab with NI-usb 6008

[Moshegt]

hello,

I'm trying to connect the NI-usb 6008 DAQ with Matlab.

I've followed the instructions given in Matlab yet matlab cant load the adaptor for NI.

I've installed NI-DAQmx 8.6

the message that i keep receiving is :

daqregister('nidaq')

ans =

Unable to load adaptor: C:\Program Files\MATLAB\R2007a\toolbox\daq\daq\private\mwnidaq.dll.
Driver files or DLL for the specified adaptor could not be found or are not installed.

the dll is instaled.

the OS is vista

daqhardwareinfo =

          ToolboxName: 'Data Acquisition Toolbox'
       ToolboxVersion: '2.10 (R2007a)'
        MATLABVersion: '7.4 (R2007a)'
    InstalledAdaptors: {'winsound'}

i'll appreciate any help on the subject,

Regards,

Do you have the National Instruments NIDAQmx drivers installed?  Can you see the device in MAX?  We have tested this device with VIsta 32.

i've installed all drivers and it appears on MAX.

i'm also using vista 32.

we checked the device on another computer with XP sp2 and it works fine with Matlab.

It sounds like the Data Acquisition Toolbox can't find your NIDAQmx drivers.  Check to make sure that the NIDAQmx DLLs are on your path.

i'm receiving this msg when trying to add the path:

"you cannot add method folders(ones that starts with '@')

or private folders to your Matlab search path."

i tried to change the folder name but it didnt do the trick.

Sorry, I meant your system path, rather than MATLAB path.  You need to find where you installed the NIDAQmx drivers, and then check that the system path (type PATH at the command prompt) contains that directory.

-Rob

[Moshegt]

the system path doesnt contain that directory.

how do i include that directory in the system path?

Googling "adding to the windows path" will offer a place to start.  I can't offer exact steps in Vista.

Hi Moshegt

I would like to point some resources that have worked for Windows XP. Just confirm that you are not missing any step (probably similar for Vista) even though you are trying to install Daqmx 8.6 in Vista x86. Use M-Series cards with DAQmx in Matlab. This is the Mathworks web site for National Instruments support: Supported Hardware - National Instruments.

I hope it helps

i've checked the system path on the XP computer were the daq works fine and it is the same as the vista computer. i dont know what to change next.

could it be related to the fact that matlab refuses to add a path to private folders?
