Elektronische systemen in een voertuig worden steeds belangrijker. Dit wordt mede veroorzaakt door de toenemende milieu- en veiligheidseisen en de wensen ten aanzien van het comfort. Dit leidt niet alleen tot een toename van het aantal regeleenheden (tot 80 stuks in een enkel voertuig) maar deze regeleenheden, die vaak van verschillende leveranciers zijn, moeten ook met elkaar communiceren. Vanaf 2008 is het voor nieuwe voertuigen die voor typegoedkeuring worden aangeboden, verplicht om ten aanzien van emissiegerelateerde storingen via de CAN-bus met een externe diagnosetester te communiceren, volgens een door Europese regelgeving vastgestelde norm. Er wordt uitgebreid aandacht besteed aan de opbouw en werking van het CAN-protocol, gezien vanuit zowel de software als de hardware. Onderwerpen die aan bod komen zijn onder andere de opbouw van een CAN-bericht, de prioriteitsregeling en de fysieke verbinding. Behalve de CAN-bus komt ook EOBD via de CAN-bus uitgebreid aan de orde: hoe werkt EOBD, en welke diagnostische gegevens zijn met behulp van een diagnosetester toegankelijk. De ‘rode draad’ wordt gevormd door de regelgeving van de Europese Unie en de internationale ISO- en SAE-normen. Deze regelgeving en normen moeten er voor zorgen dat de milieubelasting tot een minimum wordt beperkt en een milieugerelateerde storing snel gesignaleerd (en gerepareerd) wordt. Na het doorlezen en bestuderen van de inhoud wordt de CAN-bus en de diagnose via de CAN-bus voor iedereen inzichtelijk; de hobbyist die een CAN-bericht wil begrijpen en eventueel een eigen CAN-bussysteem wil opzetten, de sleutelaar die de storingen van zijn eigen voertuig wil uitlezen en repareren, maar ook de professionele diagnosetechnicus die een lastige fout moet opsporen. Daarnaast kunnen studenten en ontwikkelaars van CAN- en EOBD-applicaties door bestuderen en vooral experimenteren een basis leggen voor eigen toepassingen.

Practical Introduction to 3D Modeling from Enclosure to Front Panel Embedding a vintage component, creating a professional looking home for a circuit board, or even designing a complex apparatus complete with a chassis – these and many other challenges turn into a stimulating pleasure with FreeCAD. Once you have internalized the basic processes, there are virtually no limits to your imagination. Starting to use a new software is never straightforward – especially with a tool as versatile as FreeCAD. Manageable, but at the same time easily usable individual components provide the starting point in this book. Putting these components together later results in assemblies. In the FreeCAD universe, a workable trajectory is demonstrated. The described procedure is illustrative so the examples are easily applied to custom tasks. The devices were made by the author and illustrated with photos. Creating a 3D design is requiring some effort but the initial investment pays off soon. Besides the impressive spatial representation of the projects, the extracted drawings yield a solid base for documentation and production. Extended FreeCAD capabilities like the unfolding of sheet metal parts enormously add to efficiency and pushes models forward into practical assembly. Soon you will definitely not want to do without FreeCAD!

Schaltungen, Software und Empfangspraxis Die Kurzwellen-Empfangstechnik entwickelt sich ständig weiter. Im Mai 2007 wurde von Elektor das "Software Defined Radio mit USB-Schnittstelle" vorgestellt. Ziel war ein möglichst einfacher Empfänger, der durch den Einsatz geeigneter Software überzeugende Empfangsergebnisse liefert. Die benötigten Programme stehen auf der Elektor-Website und im Internet gratis zur Verfügung. Schon nach wenigen Monaten hatte dieser neue Empfänger eine weite Verbreitung gefunden. Zahlreiche Software-Autoren unterstützten das Projekt. Auch Bedienungshinweise, Erweiterungen sowie Tipps und Tricks findet man im Netz. Die Vielfalt der Möglichkeiten erschwert die Orientierung. Deshalb wurde dieses Buch geschrieben. Das Ziel ist ein Überblick über Aufbau, Software und Bedienung des SDR. Außerdem werden Selbstbauprojekte vorgestellt, die es erlauben, mit geringsten Kosten eigene Empfänger zu entwerfen; denn das Thema entwickelt sich laufend weiter...

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. Téléchargements GitHub
