Getting Started With Analog Input (Data Acquisition Toolbox)

Data Acquisition Toolbox

Connecting to Your Hardware

Before data can be acquired, you must "connect" the Data Acquisition Toolbox to your hardware. Connecting to your hardware requires three actions:

Registering the hardware driver adaptor
Creating an analog input object
Adding channels to the analog input object

These two topics are described below.

Registering the Hardware Driver Adaptor

When the Data Acquisition Toolbox is installed, the installed hardware driver adaptors are automatically registered. Adaptor registration involves the data acquisition engine locating all hardware driver adaptors so that it can make use of their services.

If for some reason automatic adaptor registration fails, you must manually register the adaptors. A hardware driver adaptor is manually registered with the command

daqregister('adaptor');

where adaptor is one of the supported hardware driver adaptors listed in Table 3-1. Hardware driver adaptors need to be registered only once after the Data Acquisition Toolbox is installed.

You can find out what hardware adaptors are installed on your system with the daqhwinfo function.

hwinfo = daqhwinfo;
adaptors = hwinfo.InstalledAdaptors
adaptors = 
    'winsound'
    'nidaq'
