Elektor Digital LabVIEW 2 (PDF)
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.

Elektor Digital Machine Learning mit Python für PC, Raspberry Pi und Maixduino (PDF)
Nahezu alle Menschen werden zunehmend mit den Anwendungen der „Künstlichen Intelligenz“ (KI oder AI für engl. Artificial Intelligence) konfrontiert. Musik- oder Videoempfehlungen, Navigationssysteme, Einkaufsvorschläge etc. basieren auf Verfahren, die diesem Bereich zugeordnet werden können. Der Begriff „Künstliche Intelligenz“ wurde 1956 auf einer internationalen Konferenz, dem Dartmouth Summer Research Project geprägt. Eine grundlegende Idee war dabei, die Funktionsweise des menschlichen Gehirns zu modellieren und darauf basierend fortschrittliche Computersysteme zu konstruieren. Bald sollte klar sein, wie der menschliche Verstand funktioniert. Die Übertragung auf eine Maschine wurde nur noch als ein kleiner Schritt angesehen. Diese Vorstellung erwies sich als etwas zu optimistisch. Dennoch sind die Fortschritte der modernen KI, beziehungsweise ihrem Teilgebiet dem sogenannten „Machine Learning“, nicht mehr zu übersehen. Um die Methoden des Machine Learnings näher kennenzulernen, sollen in diesem Buch mehrere verschiedene Systeme zum Einsatz kommen. Neben dem PC werden sowohl der Raspberry Pi als auch der „Maixduino“ in den einzelnen Projekten ihre Fähigkeiten beweisen. Zusätzlich zu Anwendungen wie Objekt- und Gesichtserkennung entstehen dabei auch praktisch einsetzbare Systeme wie etwa Flaschendetektoren, Personenzähler oder ein „Sprechendes Auge“. Letzteres ist in der Lage, automatisch erkannte Objekte oder Gesichter akustisch zu beschreiben. Befindet sich beispielsweise ein Fahrzeug im Sichtfeld der angeschlossenen Kamera, so wird die Information „I see a car!“ über elektronisch erzeugte Sprache ausgegeben. Derartige Geräte sind hochinteressante Beispiele dafür, wie etwa auch blinde oder stark sehbehinderte Menschen von KI-Systemen profitieren können.

Elektor Digital Visual Basic für Elektroniksteuerungen und Entwicklung (E-book)
Der PC wird schon lange nicht mehr nur als einfacher Computer verwendet, sondern hat sich zu einem Universalwerkzeug entwickelt. Dieses Buch richtet sich an diejenigen, die vorhandene oder selbstgebaute Hardware über den Computer steuern wollen. Der Einsatz von Visual Basic für die schnelle Entwicklung von Elektronikapplikationen öffnet Ihnen eine Welt, die über die Anschlüsse des PCs hinausreicht. Sobald Sie sich mit Visual Basic, seiner Entwicklungsumgebung und den angebotenen Toolsets vertraut gemacht haben, werden Dinge wie die serielle Kommunikation, Druckerports, Bitbanging, Protokoll-Emulation, die ISA-, USB- und Ethernet-Schnittstellen und die Fernsteuerung von Mess- und Testaufbauten über den GPIB-Bus in allen Einzelheiten behandelt. Zu jedem Punkt gibt es einen übersichtlichen und lauffähigen Programmcode und wo nötig existieren Schaltpläne, mit denen Sie Ihr Projekt in kurzer Zeit einsatzfähig machen können. Darüber hinausgehend erläutert dieses Buch den Umgang mit Debug-Tools bei der Suche nach Hardware-Adressen, den Aufbau einer Verbindung über TCP/IP- und UDP-Sockets und Sie lernen sogar eigene Internetserver zu programmieren. Oder wollen Sie Ihre Hardware über USB oder Ethernet anbinden und mit Visual Basic steuern? Auch die Kommunikation zwischen Programmen, DDE und das neue Grafik-Interface von Windows XP werden behandelt. Alle Programmbeispiele lassen sich mit Visual Basic 5.0, 6.0, .NET oder 2005 kompilieren. Auch die Unterschiede zwischen Visual Basic Classic und Visual Basic NET/2005 sind ausführlich erläutert.

Elektor Digital RISC-V Assembly Language Programming using ESP32-C3 and QEMU (E-book)
With the availability of free and open source C/C++ compilers today, you might wonder why someone would be interested in assembler language. What is so compelling about the RISC-V Instruction Set Architecture (ISA)? How does RISC-V differ from existing architectures? And most importantly, how do we gain experience with the RISC-V without a major investment? Is there affordable hardware available? The availability of the Espressif ESP32-C3 chip provides a way to get hands-on experience with RISC-V. The open sourced QEMU emulator adds a 64-bit experience in RISC-V under Linux. These are just two ways for the student and enthusiast alike to explore RISC-V in this book. The projects in this book are boiled down to the barest essentials to keep the assembly language concepts clear and simple. In this manner you will have “aha!” moments rather than puzzling about something difficult. The focus in this book is about learning how to write RISC-V assembly language code without getting bogged down. As you work your way through this tutorial, you’ll build up small demonstration programs to be run and tested. Often the result is some simple printed messages to prove a concept. Once you’ve mastered these basic concepts, you will be well equipped to apply assembly language in larger projects.
