Ce qui se passe en électronique est par définition invisible à l'oeil nu. L'instrument qui permet précisément de rendre visibles les signaux électriques, celui par le truchement duquel les effets de l'électronique se manifestent à nous, c'est l'oscilloscope. Hélas, quand on commence à faire de l'électronique, c'est souvent sans oscilloscope. Et l'on en est réduit à tâtonner, aussi bien physiquement que mentalement. Le jour où l'on goûte à la visualisation des signaux sur un écran, c'est une révélation. Plus personne ne souhaite se priver de cet enchantement. Pas de retour en arrière. En électronique, si l'on veut progresser dans le plaisir et dans la compréhension, il faut un oscillo. Commence alors une période d'interrogation : comment choisir ? Et à peine cette question-là aura-t-elle trouvé sa réponse, il en viendra une ribambelle d'autres que l'on peut résumer en une seule : comment se servir de l'oscilloscope de telle sorte que ce qu'il affiche corresponde bien à la réalité des signaux ? Dans ce livre, Rémy Mallard, répond clairement à ces questions. Il donne aussi de nombreuses informations pour aider son lecteur à élucider lui-même de nouveaux mystères qui ne manqueront pas de surgir. Ceux qui le connaissent déjà comme l'auteur d'un livre sur l'électronique dont le titre est un programme à lui tout seul : L'électronique pour les débutants qui sèchent les cours mais soudent sans se brûler les doigts, ainsi que d'un livre d'initiation à la programmation des microcontrôleurs PIC, savent qu'ils trouveront ici un ouvrage utile, qu'ils rouvriront souvent.

La plupart des gens sont de plus en plus confrontés aux applications de l’intelligence artificielle (IA). Les classements de musique ou de vidéo, les systèmes de navigation, les conseils d'achat, etc. reposent sur des méthodes qui peuvent être attribuées à ce domaine. Le terme intelligence artificielle a été inventé en 1956 lors d’une conférence internationale connue sous le nom de Dartmouth Summer Research Project. Une approche fondamentale consistait à modéliser le fonctionnement du cerveau humain et à construire des systèmes informatiques avancés sur cette base. Bientôt, le fonctionnement de l’esprit humain devrait être clair. Le transférer sur une machine n’était considéré qu’une petite étape. Cette notion s'est avérée un peu trop optimiste. Néanmoins, les progrès de l’IA moderne, ou plutôt de sa sous-spécialité appelée Machine Learning (ML), ne peuvent plus être niés. Dans ce livre, plusieurs systèmes différents seront utilisés pour connaître plus en détail les méthodes d’apprentissage automatique. En plus du PC, le Raspberry Pi et le Maixduino démontreront leurs capacités dans les différents projets. Outre des applications telles que la reconnaissance d'objets et de visages, des systèmes pratiques tels que des détecteurs de bouteilles, des compteurs de personnes ou un « œil qui parle » seront également créés. Ce dernier est capable de décrire acoustiquement des objets ou des visages détectés automatiquement. Par exemple, si un véhicule se trouve dans le champ de vision de la caméra connectée, l'information « Je vois une voiture ! est émis via une parole générée électroniquement. De tels appareils sont des exemples très intéressants de la manière dont, par exemple, les personnes aveugles ou gravement malvoyantes peuvent également bénéficier des systèmes d’IA.

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.

In this book the author presents all essential aspects of microcontroller programming, without overloading the reader with unnecessary or quasi-relevant bits of information. Having read the book, you should be able to understand as well as program, 8-bit microcontrollers. The introduction to microcontroller programming is worked out using microcontrollers from the PIC series. Not exactly state-of-the-art with just 8 bits, the PIC micro has the advantage of being easy to comprehend. It is offered in a DIP enclosure, widely available and not overly complex. The entire datasheet of the PIC micro is shorter by decades than the description of the architecture outlining the processor section of an advanced microcontroller. Simplicity has its advantages here. Having mastered the fundamental operation of a microcontroller, you can easily enter into the realms of advanced softcores later. Having placed assembly code as the executive programming language in the foreground in the first part of the book, the author reaches a deeper level with ‘C’ in the second part. Cheerfully alongside the official subject matter, the book presents tips & tricks, interesting measurement technology, practical aspects of microcontroller programming, as well as hands-on options for easier working, debugging and faultfinding.

If you have the right tools, designing a microprocessor shouldn’t be complicated. The Verilog hardware description language (HDL) is one such tool. It can enable you to depict, simulate, and synthesize an electronic design, and thus increase your productivity by reducing the overall workload associated with a given project.Monte Dalrymple’s Microprocessor Design Using Verilog HDL is a practical guide to processor design in the real world. It presents the Verilog HDL in a straightforward fashion and serves as a detailed introduction to reducing the computer architecture and as an instruction set to practice. You’re led through the microprocessor design process from start to finish, and essential topics ranging from writing in Verilog to debugging and testing are laid bare.The book details the following, and more: Verilog HDL Review: data types, bit widths/labeling, operations, statements, and design hierarchy Verilog Coding Style: files vs. modules, indentation, and design organization Design Work: instruction set architecture, external bus interface, and machine cycle Microarchitecture: design spreadsheet and essential worksheets (e.g., Operation, Instruction Code, and Next State) Writing in Verilog: choosing encoding, assigning states in a state machine, and files (e.g., defines.v, hierarchy.v, machine.v) Debugging, Verification, and Testing: debugging requirements, verification requirements, testing requirements, and the test bench Post Simulation: enhancements and reduction to practice Monte Dalrymple received a BSEE (with highest honors) and an MSEE from the University of California at Berkeley, where he was elected to Phi Beta Kappa. Monte started his career at Zilog, where he designed a number of successful products, including the Serial Communication Controller (SCC) family and the Universal Serial Controller (USC) family. He was also the architect and lead designer of the Z380 microprocessor. Monte started his own company, Systemyde International Corp., in 1995, and has been doing contract design work ever since. He designed all five generations of Rabbit microprocessors, a Z180 clone that is flying on the Juno mission to Jupiter, and a Z8000 clone that flies in a commercial avionics air data computer. Monte holds 16 patents as well as both amateur and commercial radio licenses. Monte wrote 10 articles for Circuit Cellar magazine between 1996 and 2010. He recently completed a side project to replace the CPU in an HP-41C calculator with a modern FPGA-based version.

Projects with Thonny-IDE, uPyCraft-IDE, and ESP32 The 'Python' programming language has enjoyed an enormous upswing in recent years. Not least, various single-board systems such as the Raspberry Pi have contributed to its popularity. But Python has also found widespread use in other fields, such as artificial intelligence (AI) or machine learning (ML). It is obvious, therefore, to use Python or the 'MicroPython' variant for use in SoCs (Systems on Chip) as well. Powerful controllers such as the ESP32 from Espressif Systems offer excellent performance as well as Wi-Fi and Bluetooth functionality at an affordable price. With these features, the Maker scene has been taken by storm. Compared to other controllers, the ESP32 has a significantly larger flash and SRAM memory, as well as a much higher CPU speed. Due to these characteristics, the chip is not only suitable for classic C applications, but also for programming with MicroPython. This book introduces the application of modern one-chip systems. In addition to the technical background, the focus is on MicroPython itself. After the introduction to the language, the programming skills learned are immediately put into practice. The individual projects are suitable for use in the laboratory as well as for everyday applications. So, in addition to the actual learning effect, the focus is also on the joy of building complete and useful devices. By using laboratory breadboards, circuits of all kinds can be realized with little effort, turning the testing and debugging of the 100% homebrew projects into an instructive pleasure. The various applications, such as weather stations, digital voltmeters, ultrasound range finders, RFID card readers or function generators, make the projects presented ideally suited for practical courses or subject and study work in the natural sciences, or in science and technology classes.
