A Software Engineering Approach to LabVIEW (National Instruments Virtual Instrumentation)by Jon Conway
Synopses & Reviews
Create more robust, more flexible LabVIEW applications—through software design principles!
Writing LabVIEW software to perform a complex task is never easy—especially when those last-minute feature requests cause a complexity explosion in your system, forcing you to rework much of your code! Jon Conway and Steve Watts offer a better solution: LCOD-LabVIEW Component Oriented Design—which, for the first time, applies the theories and principles of software design to LabVIEW programming. The material is presented in a lighthearted, engaging manner that makes learning enjoyable, even if you're not a computer scientist.
Book News Annotation:
Written for experienced programmers and testers, this book introduces software engineering principles and specifically the LabVIEW component oriented design method for creating simple software applications that offer enhanced flexibility. The British authors discuss abstraction, information hiding, design patterns, state machines, graphical user interface prototyping, reusing code, the importance of project documentation, block diagrams, and front panel standards. The final chapter walks through the planning of an example software project to test widgets.

A Software Engineering Approach to LabVIEW, by working programmers Jon Conway and Steve Watts, applies for the first time the techniques and principles of software design to LabVIEW programming. The LCOD technique designs flexibility into applications, making them more robust and much more easily adaptable to changes, even in large, industrial applications. Complete with examples and working code.

Even large, industrial-grade applications become manageable.Design to embrace flexibility first, making changes and bug fixes much less painfulPragmatic discussion of the authors' tried and tested techniques, written by--and for--working programmersCovers design principles; LCOD overview, implementation, and complementary techniques; engineering essentials; style issues; and moreComplete with practical advice on requirements gathering, prototyping, user interface design, and "rich with examples"Work through an example LCOD project (all code included on companion Web site) to tie the lessons togetherThis book is intended for test engineers, system integrators, electronics engineers, software engineers, and other intermediate to advanced LabVIEW programmers. None of the methods discussed are complex, so users can benefit as soon as they are proficient with the syntax of LabVIEW.Go to the companion Web site located at http: //author.phptr.com/watts/ for full source code and book updates.
About the Author
JON CONWAY has 20 years' experience in writing software, with half of that in LabVIEW. His fieldsof expertise include real time, robotics, databases, DAQ, DSP, and multiple software languages andoperating systems; his idea for LCOD arose from his experience gained working on complex softwareprojects. Jon is a partner in Structured Software Design Consultants of Hampshire, UK.
STEVE WATTS has 15 years of experience in writing test software, and has been programming inLabVIEW for 6 years. His areas of expertise include OOD, the Yourdon methodology, CASE tools,electronics, lasers, switching system design, DAQ, statistical process control, databases, userinterface design, software engineering, as well as a variety of programming languages. Steve is apartner in Structured Software Design Consultants of Hampshire, UK.
