DAQ - Simulink NI myDAQ

Hi,

i want to measure analog and digital Signals in Simulink with an NI myDAQ Device.

http://www.ni.com/mydaq

I use a 32bit MATLAB (Data Acquisition Toolbox Version 3.6 R2014b) in a 64bit Windows 7 PC. The Support Package is installed too.

   http://de.mathworks.com/hardware-support/ni-mydaq.html

Device (myDAQ) works with NI Software without problems

devices = 

ni: National Instruments NI myDAQ (Device ID: 'myDAQ1')
   Analog input subsystem supports:
      -2.0 to +2.0 Volts,-10 to +10 Volts ranges
      Rates from 0.1 to 200000.0 scans/sec
      2 channels ('ai0','ai1')
      'Voltage' measurement type

     Analog output subsystem supports:
        -2.0 to +2.0 Volts,-10 to +10 Volts ranges
        Rates from 0.1 to 200000.0 scans/sec
        2 channels ('ao0','ao1')
        'Voltage' measurement type

     Digital subsystem supports:
        8 channels ('port0/line0' - 'port0/line7')
        'InputOnly','OutputOnly','Bidirectional' measurement types

     Counter input subsystem supports:
        Rates from 0.1 to 100000000.0 scans/sec
        1 channel ('ctr0')
        'EdgeCount','PulseWidth','Frequency','Position' measurement types

     Counter output subsystem supports:
        Rates from 0.1 to 100000000.0 scans/sec
        1 channel ('ctr0')
        'PulseGeneration' measurement type

>> daqhardwareinfo = daqhwinfo

daqhardwareinfo = 

            ToolboxName: 'Data Acquisition Toolbox'
         ToolboxVersion: '3.6 (R2014b)'
          MATLABVersion: '8.4 (R2014b)'
      InstalledAdaptors: {3x1 cell}

>> daqinstalledadaptors = daqhardwareinfo.InstalledAdaptors

daqinstalledadaptors = 

      'nidaq'
      'parallel'
      'winsound'

>> daqregister('nidaq')

ans =

'mwnidaq.dll' successfully registered.

but i cant select the device in Simulink :(

any ideas whats wrong? what should i do? do you need more information?

thanks mscharff

Hi Manuel,

Could you find the answer to your question? I have the same problem but still waiting for a help.

Answer 1

[Manuel]

is the following Information correct?

from

https://www.linkedin.com/groups/How-interface-NImyDAQ-Matlab-134533.S.227913757

" Ivan M.

Application Engineer - The MathWorks

It's because myDAQ use Session Interface, meanwhile the blocks in Data Acquisition Toolbox that  support Simulink are available only for data acquisition devices that can be used with the legacy interface.

Any Idea/Samples/Papers what i can do?

Hey, I am facing the same Problem. Is there a way to do Simulink session based data acquisition? Regards Chris

Answer 3

[Ali Zolfagharian]

Hi,

Is there any way to use myDAQ in Simulink? Since I have the same problem.
