TRAITE DE L'ELECTRONIQUE ANLALOGIQUE & NUMERIQUE 1.

Résumé : 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.

Résumé : This book is about a state of the art tool, Flowcode, and how you can use Flowcode to develop microcontroller applications. The book starts very simply with a tutorial project and step-by-step instructions. As you go along the projects increase in difficulty and the new concepts are explained. Each project has a clear description of both hardware and software with pictures and diagrams, which explain not just how things are done but also why. Ail sources are available for free download. Since Flowcode is a high level language the intricacies of microcontroller programming are hidden from view. For that reason it doesn't make much difference whether the program is meant for a PIC, AVR or ARM microcontroller. On a high level the programs for these microcontrollers, although vastly different in internal structure, are identical. For that reason this book is on microcontroller application design in general, not just for one type of microcontroller. If you don't own the microcontroller described in a project you can usually convert it to another microcontroller quite easily. E-blocks will be used as hardware for the projects in this book. This way the hardware can be put together quickly and reliably. Fully tested units simply connect together using connectors or short flat ribbon tables to form completed projects. This book covers 45 exciting and fun projects for beginners and experts such as:

Résumé : Technology is constantly changing. New microcontrollers become available every year and old oves 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 manufacturera. They are 3a-bit microcontrollers and usually contain a decent amount of memory and a large number of on-chip peripherals. Although this book concentrates on ARvI microcontrollers from Atmel, the C programming language applies equally to other manufacturer's ARMs as well as other microcontrollers. Features of this book: Use only free or open source software. Learn how to download, set up and use free C programming tools. Start learning the C language to write simple PC programs before tackling embedded programming - no need to buy an embedded system right away! Start learning to program from the very first chapter with simple programs and slowly build from there. No programming experience is necessary! Learn by doing - type and run the example programs and exercises. Sample programs and exercises can be downloaded from the Internet. 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.

Résumé : You can use it as projects book and build more thon 50 projects for your own use. The clear explanations, schematics, and pictures of each project on a breadboard make this a fun activity. You can also use it as a study guide. The technical background information in each project explains why the project is set up the way it is, including the use of datasheets This way you'll learn a lot about the project and the microcontroller being used, and you can expand the project to suit your own needs...making it ideal for use in schools and colleges. This book can also be used as a reference guide. The explanation of the JAL programming language and ail of the expansion libraries used is unique and found nowhere else. Using the index, you can easily locate projects that serve as examples for the main commands. But even after you've built all the projects it will still be a valuable reference guide to keep next to your PC. Four microcontrollers are discussed, the 12f675, 16f628, 16f876A, and 16f877, as well as how to migrate programs from one microcontroller to another. All software used in this book can be downloaded for free, including all of the source code, a program editor, and the JAL open source programming language. This powerful and yet easy to learn language is used by hobbyists and professionals worldwide. A hardware kit is also available for purchase separately that contains all the parts to get you started, including a few microcontrollers. There is even a free support website with additional information, FAQ, and links.
