Try to keep up and create the Simulink Block diagram while watching the video.ĭata Acquisition Toolbox software provides a complete set of tools for analog input, analog output, and digital I/O from a variety of PC-compatible data acquisition hardware. You will need to know these topics when doing the rest of the tasks in this Lab Work. Read the “Introduction to Simulink” document. Watch the video Getting Started with Simulink by The MathWorks. Basic information about Simulink can be found here: Simulink is widely used in control theory and digital signal processing for simulation and design. It offers tight integration with the rest of the MATLAB environment and can either drive MATLAB or be scripted from it. Its primary interface is a graphical block diagramming tool and a customizable set of block libraries. Watch the following “Getting Started with MATLAB” video: ġ.2 Simulink Simulink, developed by The MathWorks, is a commercial tool for modeling, simulating and analyzing dynamic systems. Use the Command Window to enter variables and to run functions and M-files scripts (more about m-files later). MATLAB has the following windows: Ĭommand Window Command History Workspace Current Directory For more information, see Below we see the MATLAB Environment:
MATLAB is in use world-wide by researchers and universities. MATLAB is a short-term for MATrix LABoratory. Math and computation Algorithm development Data acquisition Modeling, simulation, and prototyping Data analysis, exploration, and visualization Scientific and engineering graphics Application development, including graphical user interface building In addition we need the Data Acquisition Toolbox for MATLAB/Simulink.ġ.1 MATLAB MATLAB is a tool for technical computing, computation and visualization in an integrated environment, e.g.,
#DAQ MATLAB 2009 INSTALL#
In order to use DAQ devices from National Instruments in MATLAB/Simulink we need to install the NI-DAQmx driver provided by National Instruments. We will use a USB-6008 DAQ device from National Instruments as an example.

29ġ Introduction In this Tutorial we will learn how to create DAQ (Data Acquisition) applications in MATLAB and Simulink. MAX – Measurement and Automation Explorer.

The focus of this tutorial is to provide examples that use your built in sound card: at the end we will show you how to use the PC DAQ cards as well.Telemark University College Department of Electrical Engineering, Information Technology and CyberneticsĭAQ in MATLAB HANS-PETTER HALVORSEN, 2012.09.11įaculty of Technology, Postboks 203, Kjølnes ring 56, N-3901 Porsgrunn, Norway. Also, you should read through the tutorial with your laptop next to you to test commands as you go. We will not explain the syntax of every MATLAB command. We are assuming that you are reading the MATLAB book and learning the basic operation of MATLAB. Much of the information used in this tutorial is translated from the MATLAB web-site, we have just distilled down some of the key points through a few simple examples. This tutorial will provide you an overview of some of the basics of data acquisition and show you how to use the toolkit. The documentation on the MATLAB web site provides a reasonable amount of information on the different commands in the toolkit. The data acqui- sition (DAQ) cards allow your computer to acquire data from many different types of sensors. We will also be using Measurement Computing data acquisition cards that will fit into your laptops PCMCIA slot, these devices will be in the class laboratory. The sound card provides convenience because it will allow you to test the DAT outside of the lab. One is the sound card built into your laptop, the microphone and speaker will serve as the data acquisition (and output) devices. We will be using this toolbox with two different pieces of hardware. The software in the toolbox allows MATLAB to acquire data from sensors and to send out electrical signals that can be used to control or drive external devices. This document will describe some of the general usage of MATLAB’s Data Ac- quisition Toolbox (DAT).
