Data Acquisition using LabVIEW

By: Behzad Ehsani

Overview of this book

NI LabVIEW's intuitive graphical interface eliminates the steep learning curve associated with text-based languages such as C or C++. LabVIEW is a proven and powerful integrated development environment to interact with measurement and control hardware, analyze data, publish results, and distribute systems. This hands-on tutorial guide helps you harness the power of LabVIEW for data acquisition. This book begins with a quick introduction to LabVIEW, running through the fundamentals of communication and data collection. Then get to grips with the auto-code generation feature of LabVIEW using its GUI interface. You will learn how to use NI-DAQmax Data acquisition VIs, showing how LabVIEW can be used to appropriate a true physical phenomenon (such as temperature, light, and so on) and convert it to an appropriate data type that can be manipulated and analyzed with a computer. You will also learn how to create Distribution Kit for LabVIEW, acquainting yourself with various debugging techniques offered by LabVIEW to help you in situations where bugs are not letting you run your programs as intended. By the end of the book, you will have a clear idea how to build your own data acquisition system independently and much more.

Installing LINX


The installation of LINX (http://sine.ni.com/nips/cds/view/p/lang/en/nid/212478) is a much improved path to support embedded platforms such as Arduino, ChipKit, and even National Instrument's own myRIO. Once LINX is downloaded and installed onto LabVIEW, under the main menu item Tools, submenu items, similar to the following screenshot, will be visible. Using LINX Firmware Wizard... will present developers with simple and easy to follow instructions to complete firmware installation.

Note that the LabVIEW function pallet for Arduino must be installed, just like any other tools package using JKI VI Package Manager before one can take full advantage of this platform.

The following image on the left depicts the first screen with multiple drop-down menus that guide the user to install the required firmware. Note the drop-down menus from which one can select Device Family, Device Type, and Firmware Program Interface.

The screenshot on the right illustrates the LINX top-level function...
