Technology is constantly changing. New microcontrollers become available every year and old ones become redundant. The one thing that has stayed the same is the C programming language used to program these microcontrollers. If you would like to learn this standard language to program microcontrollers, then this book is for you!
ARM microcontrollers are available from a large number of manufacturers. They are 32-bit microcontrollers and usually contain a decent amount of memory and a large number of on-chip peripherals. Although this book concentrates on ARM microcontrollers from Atmel, the C programming language applies equally to other manufacturer’s ARMs as well as other microcontrollers.
Features of this book

A fun way to learn the C programming language.
Ideal for electronic hobbyists, students and engineers wanting to learn the C programming language in an embedded environment on ARM microcontrollers.
Develop innovative hardware-based projects in C
The Raspberry Pi has traditionally been programmed using Python. Although this is a very powerful language, many programmers may not be familiar with it. C on the other hand is perhaps the most commonly used programming language and all embedded microcontrollers can be programmed using it.
The C language is taught in most technical colleges and universities and almost all engineering students are familiar with using it with their projects. This book is about using the Raspberry Pi with C to develop a range of hardware-based projects. Two of the most popular C libraries, wiringPi and pigpio are used.
The book starts with an introduction to C and most students and newcomers will find this chapter invaluable. Many projects are provided in the book, including using Wi-Fi and Bluetooth to establish communication with smartphones.
Many sensor and hardware-based projects are included. Both wiringPi and pigpio libraries are used in all projects. Complete program listings are given with full explanations. All projects have been fully tested and work.
The following hardware-based projects are provided in the book:
Using sensors
Using LCDs
I²C and SPI buses
Serial communication
Multitasking
External and timer interrupts
Using Wi-Fi
Webservers
Communicating with smartphones
Using Bluetooth
Sending data to the cloud
Program listings of all Raspberry Pi projects developed in this book are available on the Elektor website. Readers can download and use these programs in their projects. Alternatively, they can customize them to suit their applications.

Tout sur les protocoles et leur mise en œuvre avec Arduino
Initialement destiné aux véhicules routiers, le réseau CAN (« Controller Area Network ») et son successeur le réseau CAN FD (« Flexible Data ») ont vu leurs champs d’application s’élargir à de nouveaux domaines. L’industrie propose de nombreux modules microcontrôleurs dotés d’une interface CAN et/ou CAN FD. L’environnement de développement Arduino a démocratisé la programmation de ces modules et il existe des bibliothèques qui implémentent un pilote CAN et/ou un pilote CAN FD.
La première partie dresse un rapide historique des réseaux CAN et CAN FD et expose la problématique des lignes de transmission en abordant succinctement leur théorie et présentant des résultats de simulation Spice.
La deuxième partie est consacrée au réseau CAN, en détaillant successivement la fonction logique du réseau, les transcepteurs, les contrôleurs, la topologie la plus classique (le bus) et d’autres moins courantes, les répéteurs et les passerelles. Les aspects particuliers du protocole, tels que le bit stuffing, l’arbitrage, les trames d’erreur, la détection des erreurs sont exposés. La discussion de la fiabilité du protocole est illustrée par des exemples mettant en évidence ses faiblesses.
La troisième partie présente le protocole CAN FD, ses deux variantes CAN FD ISO et CAN FD non ISO, leurs fiabilités, leurs faiblesses, mises en évidence par des exemples. Différents transcepteurs et contrôleurs CAN FD sont décrits.
La quatrième partie est dédiée aux applications : comment utiliser les services d’un pilote, concevoir une messagerie, utiliser un analyseur logique. Deux exemples d’application terminent cette partie.
Ce livre s’adresse aux amateurs et aux ingénieurs non spécialistes pour comprendre les possibilités qu’offre un réseau CAN et comment on le met en œuvre. Un enseignant trouvera des informations pour approfondir ses connaissances et pour concevoir des travaux pratiques. Une connaissance des microcontrôleurs, de leur programmation, de l’électronique numérique aidera à la lecture des schémas. La connaissance du langage C++ et du langage de simulation électronique Spice facilitera la compréhension des programmes qui sont décrits dans le livre. Tous les codes source sont disponibles sur le dépôt GitHub de l’auteur.

L'ESP8266 d'Espressif est une puce Wi-Fi dotée d'une pile TCP/IP complète et d'une capacité de microcontrôleur. Il a fait des vagues dans la communauté des fabricants grâce à son prix bas.
Mais de nombreux développeurs étaient mécontents de la consommation électrique élevée de l'ESP8266. L'ESP32, équipé d'un coprocesseur ULP (Ultra Low Power), propose un remède à cela.
Cet e-book présente un certain nombre de projets mettant en vedette ESP32 et ESP8266 et démontre leurs performances dans différentes applications.

Computer vision is probably the most exciting branch of image processing, and the number of applications in robotics, automation technology and quality control is constantly increasing. Unfortunately entering this research area is, as yet, not simple.
Those who are interested must first go through a lot of books, publications and software libraries. With this book, however, the first step is easy. The theoretically founded content is understandable and is supplemented by many practical examples. Source code is provided with the specially developed platform-independent open source library IVT in the programming language C/C++. The use of the IVT is not necessary, but it does make for a much easier entry and allows first developments to be quickly produced.
The authorship is made up of research assistants of the chair of Professor Ruediger Dillmann at the Institut für Technische Informatik (ITEC), Universitaet Karlsruhe (TH). Having gained extensive experience in image processing in many research and industrial projects, they are now passing this knowledge on.
Among other subjects, the following are dealt with in the fundamentals section of the book: Lighting, optics, camera technology, transfer standards, camera calibration, image enhancement, segmentation, filters, correlation and stereo vision.
The practical section provides the efficient implementation of the algorithms, followed by many interesting applications such as interior surveillance, bar code scanning, object recognition, 3-D scanning, 3-D tracking, a stereo camera system and much more.
