Microcontrollers have become an indispensable part of modern electronics. They make things possible that vastly exceed what could be done previously. Innumerable applications show that almost nothing is impossible. There’s thus every reason to learn more about them, but that raises the question of where to find a good introduction to this fascinating technology. The answer is easy: this Microcontroller Basics book, combined with the 89S8252 Flash Board project published by Elektor Electronics. However, this book offers more than just a basic introduction. It clearly explains the technology using various microcontroller circuits and programs written in several different programming languages. Three microcontrollers from the 8051 family are used in the sample applications, ranging from the simple 89C2051 to the AN2131, which is designed to support USB applications. The programming tools include assemblers, Basic-52 and BASCOM-51, and several C compilers. Every reader can thus find the programming environment most suitable to his or her needs. In the course of the book, the reader gradually develops increased competence in converting his or her ideas into microcontroller circuitry. All of the sample programs can be downloaded from the Elektor Electronics website or the author’s website. That has the added advantage that the latest versions are always available.

Mastering the Language and the Development Platform Many people would like to learn Java but getting started is not easy since programming with Java requires at least two things: mastering the programming language and the development environment. With the help of many examples, this book shows how the language is structured. In addition, it employs the Eclipse development environment as an example of a powerful tool to teach developing Java programs. In Basics, the first part of the book, you acquire your Java and Eclipse basic knowledge. This part lays the programming foundations, gives you an overview of Java technology, and shows you what is special about object-oriented programming. In the second part called Java Language, everything revolves around the subtleties of the Java language and this is where the first small Java applications are created, aided by a fine blend of the knowledge part and practical exercises. Java Technology is both the name and the focus of the third part which also introduces you to the rules to observe when programming, what class libraries are and what advantages they have. In addition, you will learn how to test programs, what algorithms are, and how to program them. The fourth part, Java Projects, enables you to apply all the previous elements in an application with a graphical user interface. The project shows how to develop a larger application piece by piece with the Eclipse development environment. The Appendix concludes with a section on frequent errors that can occur when working with Eclipse, and a Glossary.

Maîtrise de la puce RP2040 avec plus de 60 projets à réaliser et à programmer Les cartes Raspberry Pi Pico et Pico W sont animées par un microcontrôleur ARM Cortex M0+ RP2040 à double coeur, rapide, efficace et peu coûteux, qui fonctionne jusqu'à 133 MHz et dispose de 264 Ko de SRAM et de 2 Mo de mémoire Flash. Outre une vaste mémoire, le Pico et le Pico W disposent de nombreuses broches GPIO et d'interfaces telles que CA/N, SPI, I²C, UART, MLI, de fonctions de temporisation, d'une interface de débogage matériel et d'un capteur de température interne. La carte Raspberry Pi Pico W comporte en plus une puce CYW43439 Bluetooth et Wi-Fi d'Infineon. Au moment de la rédaction de ce livre, le micrologiciel Bluetooth pour le Pico W n'était pas encore disponible. Le Wi-Fi à 2,4 GHz est toutefois entièrement pris en charge avec les protocoles 802.11b/g/n. Ce livre est une introduction à l'utilisation du Raspberry Pi Pico W avec le langage de programmation MicroPython. Les quelque soixante projets testés et opérationnels sont présentés à l'aide de l'environnement de développement intégré (EDI) Thonny. Les sujets abordés sont nombreux : Installation de MicroPython sur le Raspberry Pi Pico depuis un PC Interruptions de l'horloge et interruptions externes Convertisseur analogique-numérique (CA/N) Capteurs de température interne et externe Capteurs externes (pression, humidité, pouls, à ultrasons) Enregistrement de données MLI, UART, I²C et SPI Bluetooth, Wi-Fi et applis sur smarphone Convertisseur numérique-analogique (CN/A) Tous les projets ont été testés et éprouvés. Ils peuvent être mis en oeuvre sur le Raspberry Pi Pico ainsi que sur le Raspberry Pi Pico W. Toutefois les projets avec une liaison Wi-Fi ne fonctionnent que sur le Pico W. Une petite expérience en programmation et en électronique est nécessaire pour suivre les projets. De brèves descriptions, des schémas fonctionnels, des schémas détaillés du câblage des montages et des listings MicroPython complets sont fournis pour tous les projets.

Dit boek is bedoeld voor diegenen die zich bezig houden met geluidsversterking en geluidsdistributie. Het gaat in op de akoestische eigenschappen van open, halfopen en omsloten ruimten. Belangrijk is hoe luidsprekers aangepast kunnen worden op allerlei omgevingen. Meestal moet men een keuze maken uit het aanbod van luidsprekers en microfoons. De vraag is dan welke luidspreker en microfoon de juiste keuze zijn. En hoe deze moeten worden opgesteld waarbij spraak- en muziekverstaanbaarheid en de maximaal haalbare versterking in de live-situatie de belangrijkste criteria zijn. Dit boek geeft antwoord op die vragen. Verder wordt de lezer meegenomen naar het ontwerpen van luidsprekers op basis van de T/S parameters. Met eenvoudige software is het mogelijk akoestische en mechanische elementen van een luidspreker met de eventuele behuizing te vertalen naar de elektrische analogieën, zodat de luidspreker op de PC gesimuleerd kan worden. Aan de hand van rekenvoorbeelden worden bovenstaande simulaties ondersteund. Tot slot zijn in de referentielijst een aantal internetlinks opgenomen waaruit zeer waardevolle gegevens gehaald kunnen worden. De auteur, Peter Swarte, is natuurkundig ingenieur en was werkzaam bij Philips. Momenteel is hij_eigenaar van consultancy bureau P.A.S. Electro Acoustics en is hij actief lid van zowel het NAG (Nederlands Akoestisch Genootschap) als de AES (Audio Engineering Society).

Dieses Buch nimmt Sie mit auf eine Entdeckungsreise in die Welt der digitalen Elektronik. Nach dem Aufbau einer soliden Wissensbasis hierüber verlagert sich der Schwerpunkt zur programmierbaren Logik. Wie lassen sich mit vorhandenen Bausteinen logische Systeme aufbauen und wie koppelt man sie sicher und störungsfrei an die analoge Außenwelt? Das sind Fragen, die das Buch beantwortet. Moderne logische Systeme sind so komplex, dass deren Aufbau mit separaten Bauelementen wie einzelnen Gattern, Flipflops, Zählern oder Teilern eine fast unmögliche Aufgabe ist. Deshalb beschäftigt sich das Buch in der zweiten Hälfte mit der programmierbaren Logik in Form von FPGA- und CPLD-ICs. Sie lernen Methoden kennen, die als Brücke zwischen dem klassischen Design und der zeitgemäßen Entwicklung mit FPGA fungieren. Neben dem schematischen FPGA-Entwurf setzt sich das Buch auch mit Sprachen wie Verilog und VHDL auseinander. Das abschließende Projekt, eine Uhr mit Alarmfunktion in Verilog und VHDL, zeigt den praktischen Nutzen der programmierbaren Logik. Neben den erforderlichen Programmierkenntnissen ist auch der praktische Schaltungsaufbau von Bedeutung. Der Autor erläutert die wesentlichen Bedingungen hierfür, beispielsweise die der erforderlichen Stromversorgung und der optimalen (Analog-)Signalverarbeitung. Alle in diesem Buch besprochenen Beispiele lassen sich mit der kostenfreien FPGA-Entwicklungsumgebung Quartus von Altera realisieren.
