Communication between Matlab and NI DAQ USB 6229

Asked by Alan Armstrong on 22 Aug 2012


I'm using Matlab R2012a and NI DAQ USB6229.

When I use the following line of code:

>> loadlibrary('nicaiu.dll','nidaqmx.h','alias','myni')

I get an error and it appears that the library did not load:

Warning: Warnings messages were produced while parsing.  Check the functions you intend to use for correctness.  Warning text can be
viewed using:
> In loadlibrary at 344 
Error using loadlibrary (line 419)
There was an error loading the library "C:\Documents and Settings\Administrator\My Documents\PhD\MATLAB\Experiment_2\nicaiu.dll"
A dynamic link library (DLL) initialization routine failed.
Caused by:
    Error using loaddefinedlibrary
    A dynamic link library (DLL) initialization routine failed.

Can anybody help me with this?

thanks in advance,

Are you using the 32 bit or 64 bit MATLAB? Is the dll for 32 or 64 bit?
