Data Acquisition Toolbox™

Other Things to Try

Registering the Hardware Driver Adaptor

When you first create a device object, the associated hardware driver adaptor is automatically registered so that the data acquisition engine can make use of its services.

The hardware driver adaptors included with the toolbox are all located in the daq/private directory. The full name for each adaptor is shown below.

Supported Vendors/Device Types and Full Adaptor Names

If for some reason a toolbox adaptor is not automatically registered, then you need to register it manually using the daqregister function. For example, to manually register the sound card adaptor:

daqregister('winsound');

If you are using a third-party adaptor, then you might need to register it manually. If so, you must supply the full pathname to daqregister. For example, to register the third-party adaptor myadaptor.dll:

daqregister('C:/MATLAB/toolbox/daq/myadaptors/myadaptor.dll')

Notes   You must install the associated hardware driver before adaptor registration can occur. The Traditional NI-DAQ adaptor will be deprecated in a future version of the toolbox. If you create a Data Acquisition Toolbox™ object for Traditional NI-DAQ adaptor beginning in R2008b, you will receive a warning stating that this adaptor will be removed in a future release. See the supported hardware page at www.mathworks.com/products/daq/supportedio.html for more information. The Parallel adaptor will be deprecated in a future version of the toolbox. If you create a Data Acquisition Toolbox™ object for 'parallel' beginning in R2008b, you will receive a warning stating that this adaptor will be removed in a future release. See the supported hardware page at www.mathworks.com/products/daq/supportedio.html for more information.

Contacting The MathWorks

If you need support from The MathWorks, visit our Web site at http://www.mathworks.com/support/.

Before contacting The MathWorks, you should run the daqsupport function. This function returns diagnostic information such as:

• The versions of the MathWorks™ products you are using

• Your MATLAB software path

• The characteristics of your hardware

The output from daqsupport is automatically saved to a text file, which you can use to help troubleshoot your problem. For example, to have the MATLAB software generate this file for you, type

daqsupport
