ARM Cortex-M Embedded Design from 0 to 1 Hobbyists can mash together amazing functional systems using platforms like Arduino or Raspberry Pi, but it is imperative that engineers and product designers understand the foundational knowledge of embedded design. There are very few resources available that describe the thinking, strategies, and processes to take an idea through hardware design and low-level driver development, and successfully build a complete embedded system. Many engineers end up learning the hard way, or never really learn at all. ARM processors are essentially ubiquitous in embedded systems. Design engineers building novel devices must understand the fundamentals of these systems and be able to break down large, complicated ideas into manageable pieces. Successful product development means traversing a huge amount of documentation to understand how to accomplish what you need, then put everything together to create a robust system that will reliably operate and be maintainable for years to come. This book is a case study in embedded design including discussion of the hardware, processor initialization, low‑level driver development, and application interface design for a product. Though we describe this through a specific application of a Cortex-M3 development board, our mission is to help the reader build foundational skills critical to being an excellent product developer. The completed development board is available to maximize the impact of this book, and the working platform that you create can then be used as a base for further development and learning. The Embedded in Embedded program is about teaching fundamental skill sets to help engineers build a solid foundation of knowledge that can be applied in any design environment. With nearly 20 years of experience in the industry, the author communicates the critical skill development that is demanded by companies and essential to successful design. This book is as much about building a great design process, critical thinking, and even social considerations important to developers as it is about technical hardware and firmware design.

Le monde de l'électronique est à la fois vaste et… tout petit ! Voici un livre qui confirme ces deux constatations contradictoires. En effet, en électronique, tout touche à tout, d'une manière ou d'une autre. Le plus petit détail peut avoir les plus grandes conséquences, et pas toujours celles que l'on attendrait. L'objectif de l'auteur de cette série d'articles autonomes intitulée hors-circuits, réunis ici en un livre, n'est pas de vous tenir par la main. Robert Lacoste, électronicien professionnel de haut-niveau, vous donne des pistes pour comprendre ce qui paraît mystérieux. Il vous guide juste assez pour vous permettre ensuite de progresser tout seul. Avec lui, non seulement vous repousserez vos propres limites, mais saurez aussi détecter celles du matériel et du logiciel que vous utilisez. En vous invitant à repasser par les notions de physique de base, il vous permettra de séparer les véritables progrès techniques des laïus commerciaux. Les bases, ça peut mener loin D'où vient la sensibilité d'un récepteur d'ondes radio ? Pourquoi le téléchargement d'une vidéo sur votre portable est-il beaucoup plus lent à la campagne qu'en centre-ville ? Si pour vous la réponse technique à des questions comme celles-ci (et bien d'autres que vous n'osez peut-être même pas vous poser) n'est pas évidente, ce livre vous aidera à y voir plus clair. Oui, on peut être à l'aise avec les microcontrôleurs, mais dérouté par le comportement d'un simple transistor. Vous sentez-vous concerné par de telles interrogations ? Ce livre est donc pour vous. Sans aucune formule mathématique qui ne soit pas à la portée d'un lycéen, il balaye tout le champ de l'électronique, depuis l'analogique jusqu'au traitement numérique du signal en passant par le domaine si redouté des hautes-fréquences. La théorie ne s'y éloigne jamais beaucoup de la loi d'Ohm ! Avec des mots simples, l'auteur explique comment ça marche, pourquoi parfois ça ne marche pas comme on veut, et comment mieux utiliser différentes techniques dans vos propres projets pour que ça marche.

This book is intended for electronics enthusiasts and professionals alike, who want a much deeper understanding of the incredible technology conquests over the pre-digital decades that created video. It details evolution of analogue video electronics and technology from the first electro-mechanical television, through advancements in Cathode Ray Tubes, transistor circuits and signal processing, up to the latest analogue, colour-rich TV, entertainment devices and calibration equipment. Key technological advances that enabled monochrome video and, eventually, colour are explained. The importance, compromises and techniques of maintaining crucial backward legacy compatibilities are described. The generation, signal processing and playback of analogue video signals in numerous capture, display, recording and playback devices together with operating principles and practices are examined. Technical and, often, political merits and deficiencies of key national and international video standards are highlighted. Several formats are shown to win and ultimately to co-exist. This book begins at fairly basic levels; concepts are introduced with human physiological perceptions of light and colour explained. This leads to the subject matter of luminance and chrominance; their equations and the circuits to process. There is full, detailed analysis of waveform shapes and timings inside video equipment and relevant popular connections e.g. S-video. Several analogue video projects which you can build yourself are also included in this book; with schematics, circuit board layouts and calibration steps to help you obtain the best results. The book makes use of many colour pages where the subject matter demands it (e.g. test cards). If you really want a deeper understanding of analogue video then this book is for you!

Meten is voor een praktiserend elektronicus even vanzelfsprekend als ademhalen. Of het nu om het ontwikkelen van nieuwe schakelingen gaat, de controle van elektronische apparaten tijdens de productiefase of om het foutzoeken in defecte apparatuur: meetapparaten zijn het belangrijkste gereedschap en worden voortdurend gebruikt. 'Weet wat je meet', luidt een bekende uitspraak. En zo is het maar net: om zichzelf geen rad voor ogen te draaien moet de elektronicus weten wat hij doet, moet hij de nauwkeurigheid van zijn meetapparatuur en vooral de voor- en nadelen van de toegepaste meetmethode kennen. En hier steekt dit boek de lezer de helpende hand toe: uitgaand van theoretische beschouwingen en definities van de belangrijkste begrippen van de meettechniek begeleidt het de lezer bij de reis van eenvoudige wijzerinstrumenten via multimeter en oscilloscoop tot en met FFT-analyzers en gespecialiseerde meetapparaten zoals audio-analyzers, geluidsdrukmeters, apparaat- en installatietesters.

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.

STmicroelectronics’ wireless IoT & wearable sensor development kit ‘SensorTile.box’ is a portable multi-sensor circuit board housed in a plastic box and developed by STMicroelectronics. It is equipped with a high-performance 32-bit ARM Cortex-M4 processor with DSP and FPU, and various sensor modules, such as accelerometer, gyroscope, temperature sensor, humidity sensor, atmospheric pressure sensor, microphone, and so on. SensorTile.box is ready to use with wireless IoT and Bluetooth connectivity that can easily be used with an iOS or Android compatible smartphone, regardless of the level of expertise of the users. SensorTile.box is shipped with a long-life battery and all the user has to do is connect the battery to the circuit to start using the box. The SensorTile.box can be operated in three modes: Basic mode, Expert mode, and Pro mode. Basic mode is the easiest way of using the box since it is pre-loaded with demo apps and all the user has to do is choose the required apps and display or plot the measured data on a smartphone using an app called STE BLE Sensor. In Expert mode users can develop simple apps using a graphical wizard provided with the STE BLE Sensor. Pro mode is the most complex mode allowing users to develop programs and upload them to the SensorTile.box. This book is an introduction to the SensorTile.box and includes the following: Brief specifications of the SensorTile.box; description of how to install the STE BLE Sensor app on an iOS or Android compatible smartphone required to communicate with the box. Operation of the SensorTile.box in Basic mode is described in detail by going through all of the pre-loaded demo apps, explaining how to run these apps through a smartphone. An introduction to the Expert mode with many example apps developed and explained in detail enabling users to develop their own apps in this mode. Again, the STE BLE Sensor app is used on the smartphone to communicate with the SensorTile.box and to run the developed apps. The book then describes in detail how to upload the sensor data to the cloud. This is an important topic since it allows the sensor measurements to be accessed from anywhere with an Internet connection, at any time. Finally, Pro mode is described in detail where more experienced people can use the SensorTile.box to develop, debug, and test their own apps using the STM32 open development environment (STM32 ODE). The Chapter explains how to upload the developed firmware to the SensorTile.box using several methods. Additionally, the installation and use of the Unicleo-GUI package is described with reference to the SensorTile.box. This PC software package enables all of the SensorTile.box sensor measurements to be displayed or plotted in real time on the PC.

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.

Quite unintentionally a one-page story on an old Heathkit tube tester in the December 2004 edition of Elektor magazine spawned dozens of ‘Retronics’ tales appearing with a monthly cadence, and attracting a steady flow of reader feedback and contributions to the series. Since launching his Retronics columns, Elektor Editor Jan Buiting has never been short of copy to print, or vintage equipment to marvel at. This book is a compilation of about 80 Retronics installments published between 2004 and 2012. The stories cover vintage test equipment, prehistoric computers, long forgotten components, and Elektor blockbuster projects, all aiming to make engineers smile, sit up, object, drool, or experience a whiff of nostalgia. To reflect that our memories are constantly playing tricks on us, and honoring that “one man’s rubbish is another man’s gem”, the tales in the book purposely have no chronological order, and no bias in favor of transistor or tube, microprocessor or discrete part, audio or RF, DIY or professional, dry or narrative style. Although vastly diff erent in subject matter, all tales in the book are told with personal gusto because Retronics is about sentiment in electronics engineering, construction and repair, be it to reminisce about a 1960s Tektronix scope with a cleaning lady as a feature, or a 1928 PanSanitor box for dubious medical use. Owners of this book are advised to not exceed one Retronics tale per working day, preferably consumed in the evening hours under lamp light, in a comfortable chair, with a piece of vintage electronic equipment close and powered up.

RFID technology has conquered many areas in which barcodes, magnetic strips and contact smartcards were used previously. Everyday applications, such as electronic ticketing, access cards, debit cards and electronic identity documents would not be possible without this technology. MIFARE is the most widely used RFID technology, and this book provides a practical and comprehensive introduction to it. Among other things, the initial chapters cover physical fundamentals, relevant standards, RFID antenna design, security considerations and cryptography. The complete design of a reader’s hardware and software is described in detail. The reader’s firmware and the associated PC software support programming using any .NET language. The specially developed PC program, “Smart Card Magic.NET”, is a simple development environment that supports sending commands to a card at the click of a mouse, as well as the ability to create C# scripts. Alternatively, one may follow all of the examples using Visual Studio 2010 Express Edition. Finally, the major smart card reader API standards are introduced. The focus is on programming contactless smartcards using standard PC/SC readers using C/C++, Java and C#.

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. Téléchargements GitHub

Le langage de programmation Python est apprécié par les pédagogues parce que sa syntaxe le rend facile à comprendre. Il s'est également imposé chez les informaticiens expérimentés. La société Adafruit a développé une version spéciale de Python pour l'embarquer sur les microcontrôleurs à 32 bits : CircuitPython. Ce livre permettra au lecteur de s'initier à la programmation en CircuitPython sur deux cartes : Feather BlueFruit Sense (également appelée Feather nRF52840 Sense) et CLUE nRF52840 Express. Chacune est animée par le SoC nRF52840 de NORDIC avec une architecture à 32 bits. Pour ce voyage dans le monde de la programmation embarquée, l'auteur sort du chemin classique, à savoir un cours complet sur la programmation orientée objet appliquée à ce langage. Il préfère emmener le lecteur directement sur le terrain avec des projets qui mettent en oeuvre les cartes et différents périphériques. Plus d'une quarantaine d'exemples et de montages permettent de découvrir la richesse de CircuitPython. Toutefois l'auteur s'est imposé une limite pour ne pas décourager les novices : le code de chaque projet ne dépasse jamais la centaine de lignes. Pour ce qui est du matériel, là aussi la simplicité domine : aucun programmateur, un simple PC suffit ; aucun soudage grâce au câblage sur platine d'essai. Les cartes d'extension FeatherWing à enficher sur la Feather nRF52840 Sense permettent de démultiplier ses fonctions : matrice de LED, enregistreur de données, écran à encre électronique, écran OLED, écran TFT, commande de moteurs, audio, relais… Toutes les étapes (assemblage des différents composants, installation des bibliothèques requises, programmation, tests…) sont expliquées en détail. Le code des différents exemples et projets est disponible sur Github. Le résultat de chaque projet est même présenté sur de courtes vidéos disponibles sur YouTube. À la fin de sa lecture, le nouveau Pythonien pourra facilement approfondir les notions abordées et donner vie à ses propres projets grâce aux outils qu'il aura essayés. Ce livre s'adresse aux lycéens et étudiants ainsi qu'à toute la communauté des makers. Chaîne YouTube de l'auteur YouTube (Michaël Bottin)

This book focuses more on practical aspects than on theory, and it has an contemplative nature, as though the author were viewing amplifiers from above. Knowledge elements are integrated and placed in the context of a broad overview. Even now tube amplifiers still sound great perhaps better than ever before. In part that is because we now have access to modern components such as toroidal output transformers, extremely high-quality resistors and capacitors, and many sorts of wire with good acoustic properties. Modern audio sources, such as CD players, and the latest top-end loudspeakers also enable us to appreciate how well tube amplifiers reproduce music even better than before. This new book from Menno van der Veen looks at tube amplifiers from more than just a theoretical perspective. It focuses primarily on the design phase, where decisions must be taken with regard to the purpose and requirements of the amplifier, and it addresses the following questions: How do these aspects relate to subjective and objective criteria? Which circuits sound the best, and why? If you want to develop and market an amplifier, what problems should you expect? What are the significance and meaning of measurements? Are they still meaningful, or have they lost their relevance? Thanks to the enormous processing power of computers, we can now measure more details than ever before. How can these new methods be applied to tube amplifiers? Previously it was sufficient to measure the frequency range, power and distortion of an amplifier in order to characterize the amplifier. Are these measurements still sufficient, or should we start measuring according to how we hear, using real music signals instead of waveforms from signal generators? The author sketches a future where amplifier measurements that conform to our sense of hearing enable us to arrive at new insights. This book focuses more on practical aspects than on theory, and it has an contemplative nature, as though the author were viewing amplifiers from above. Knowledge elements are integrated and placed in the context of a broad overview.
