Hello friends, i am trying to use a 'softscope' but am getting errors. Basically am not able to use it. This is the error "SOFTSCOPE can not be started: The DAQ Legacy Interface is not supported on this platform.".

i tried to use "daq.createSession('ni')" then it gave me this: 'The vendor 'ni' is not known. Use 'daq.getVendors()' for a list of vendors.' Then i used

'daq.getVendors()', this was the output: 
Data acquisition vendor 'National Instruments':
-------
          _ _ID: 'ni'
    FullName: 'National Instruments'
AdaptorVersion: '3.8 (R2015b)'
DriverVersion: 'unknown'
IsOperational: false

Warning: Diagnostic Information from vendor: NI: The required MEX file to communicate with National Instruments hardware could not be loaded.

The attempt gave the Error ID of

'MATLAB:invalidMEXFile' and the message
'Invalid MEX-file 'C:\Program Files\MATLAB\R2015b\toolbox\daq\daq\+daq\+ni\+NIDAQmx\private\mexNIDAQmx.mexw64': A dynamic link library (DLL)
initialization routine failed.'.__

To understand my problem i guess you might need this__

> daqsupport('ADAPTOR','myfile.txt') which outputs this on my system:

It appears the key is the last line:

'Invalid MEX-file

'C:\Program Files\MATLAB\R2015b\toolbox\daq\daq\+daq\+ni\+NIDAQmx\private\mexNIDAQmx.mexw64':

The specified module could not be found.']

I don't know from whence cometh the the required driver files but it appears that you need to install and updated DAQ Toolbox to go with the update to the Matlab version.

Hey @dpb, i appreciate your interest in help me out, and i do understand you explanation, but how do i update it, fist of all, how or from where can i download 'DAQ toolbox'? please help.

[patrick mumba]

Hey i did download and it is working. Thanks a lot!

[dpb]

I've not had the DAQ Toolboxen so wasn't sure whether the mex files were TMW or vendor supplied; hence I wasn't sure whether needed only to update the Toolbox or also neeeded stuff directly from NI. I figured probably it was all in the toolbox but just wasn't positive.
