Getting Started with the Data Acquisition Toolbox (Data Acquisition Toolbox)

Data Acquisition Toolbox

Demos

The toolbox includes a large collection of demos, which are available through the daqschool interface. To launch this interface, type daqschool at the command line.

daqschool

You can also launch individual demos by typing the appropriate M-file name at the command line. Alternatively, you can launch a toolbox demo through the MATLAB Demo window by typing

demo toolbox 'Data Acquisition'

The data acquisition demos, organized by device object, are listed below.

Note Most analog input and analog output demos require that you have a sound card installed. The digital I/O demos require that you have a supported National Instruments board with digital I/O capabilities.

daqschool is shown below.
