Data Acquisition Toolbox

What Is the Data Acquisition Toolbox?

The Data Acquisition Toolbox is a collection of M-file functions and MEX-file dynamic link libraries (DLLs) built on the MATLAB® technical computing environment. The toolbox provides you with these main features:

• A framework for bringing live, measured data into MATLAB using PC-compatible, plug-in data acquisition hardware
• Support for analog input (AI), analog output (AO), and digital I/O (DIO) subsystems including simultaneous analog I/O conversions
• Support for these popular hardware vendors/devices:
• Agilent Technologies E1432A/33A/34A VXI modules
• Keithley boards that use DriverLINX drivers.
• Measurement Computing Corporation (ComputerBoards) boards
• National Instruments boards that use NI-DAQ software (except SCXI)
• Parallel ports LPT1-LPT3
• Windows sound cards

• Additionally, you can use the Data Acquisition Toolbox Adaptor Kit to interface unsupported hardware devices to the toolbox.

• Event-driven acquisitions

Exploring the Toolbox

A list of the toolbox functions is available to you by typing

• help daq
  

You can view the code for any function by typing

• type function_name
  

You can view the help for any function by typing

• daqhelp function_name
  

You can change the way any toolbox function works by copying and renaming the M-file, then modifying your copy. You can also extend the toolbox by adding your own M-files, or by using it in combination with other products such as the Signal Processing Toolbox or the Instrument Control Toolbox.
