Das Programmpaket Laboratory Virtual Instrument Engineering Workbench (oder kurz LabVIEW) ist ein international anerkannter Standard zur Entwicklung und Gestaltung von Messgeräten und Prozesssteueroberflächen. Seine Universalität konfrontiert den LabVIEW-Einsteiger allerdings mit einer unübersichtlichen Vielfalt von Funktionen, die er ohne fundierte Anleitung kaum überblicken kann. Hier setzt diese neue mehrteilige Lehrbuchreihe an: Von Grund auf werden in einfach nachvollziehbaren Schritten der Aufbau, die Struktur und die Verwendung von LabVIEW erklärt, in praktischen Beispielen dargestellt und mit Übungen vertieft. Die notwendigen Vorkenntnisse sind äußerst gering, die erreichbaren Ergebnisse dagegen äußerst sehenswert. Der erste Band erläutert die Grunddatentypen und die zugehörigen numerischen Grundfunktionen ebenso ausführlich wie die elementaren Programmstrukturen. Im folgenden Band liegt der Schwerpunkt bei der Kopplung beliebiger Mikrocontrollersysteme über die serielle (USB-)Schnittstelle an den PC und an LabVIEW. Im dritten Band stehen Entwurf und Betrieb kompletter MSR-Systeme mit Hard- und Softwarekomponenten der wichtigsten Messtechnikhersteller im Vordergrund, einschließlich Fernsteuerung, -überwachung und -diagnose über das Internet oder WLAN-Systeme. Diese Lehrbuchreihe richtet sich an Schüler/Auszubildende technischer Bildungseinrichtungen, an Studenten von Fachhochschulen/Universitäten und an den engagierten Praktiker in der Industrie oder im privaten Bereich.

Alle verwendeten Code-Beispiele stehen unter "Downloads" zum Herunterladen bereit. Mit den vorgestellten Konzepten können auf einfache Weise eigene Ergebnisse erzielt und somit der Lernprozess unterstützt werden. Auch professionelle Software-Tools von Microsoft stehen zum kostenlosen Download zur Verfügung. Die Anwender stellen für Microsoft's Visual Studio 2010 eine Vielzahl von Steuerungen, Eigenschaften, Methoden und Ereignissen bereit. Leser, die die Hardware eines PCs steuern wollen, erhalten genaue Anleitungen. In den Kapiteln über PC-Schnittstellen wird das Erbe der seriellen und parallelen Ports besprochen, analoge Zugänge steuern die Soundkarte und verwenden DirectX-Treiber von Microsoft. Die Anbindung des allgegenwärtigen USB-Ports wird genau erklärt, einschließlich des Entwurfs von Hard- und Software zur Steuerung eines PIC-Boards via USB. Viele Programmbeispiele, praktische Übungen und Links auf Support-Videos vervollständigen dieses Buch – das teilweise in englischer Originalsprache. Universitätsdozenten bieten für die meisten Kapitel Hilfen in Form von herunterladbaren PowerPoint-Präsentationen an. Das vorliegende Buch von Dr. John Allwork berücksichtigt bei der C#-Entwicklung auch die neue Version Visual Studio 2010 und das Microsoft-Betriebssystem Windows 7.
