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

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?
