Der Autor zeigt in diesem Buch alle wichtigen Aspekte der Mikrocontroller-Programmierung, ohne den Leser mit unnötigen oder nebensächlichen Informationen zu überladen. Am Ende der Lektüre ist der Leser in der Lage, 8-Bit-Mikrocontroller zu verstehen und zu programmieren. Die Einführung in die Mikrocontroller-Programmierung dekliniert der Autor an Mikrocontrollern aus der PIC-Familie durch. Der PIC mit seinem 8-Bit-Design ist nicht auf dem modernsten technischen Stand, aber dafür einfach zu verstehen. Er wird in einem DIP-Gehäuse angeboten, ist überall erhältlich und nicht besonders komplex. Das gesamte Datenblatt des PICs ist um Dekaden kürzer als die Architekturbeschreibung, die den Prozessor eines fortgeschrittenen Mikrocontrollers beschreibt. Die Einfachheit hat ihre Vorteile. Wer versteht, wie ein Mikrocontroller grundlegend funktioniert, kann sich später in fortgeschrittene Softcores einarbeiten. Steht im ersten Teil des Buches Assembler als ausführende Programmiersprache im Vordergrund, so geht der Autor im zweiten Teil seines Buches vertiefend auf C ein. Quasi nebenbei entführt das Buch den Leser in die Tiefen der praktischen Arbeit mit Mikrocontrollern, erklärt interessante Messtechnik und zeigt Möglichkeiten zur Arbeitserleichterung und Fehlersuche.

Er zijn niet zoveel boeken te vinden over het ontwerpen en bouwen van zenders met een klein uitgangsvermogen. Dit boek beschrijft nauwkeurig de werking en bouw van maar liefst twintig audio- en videozender(tje)s. Daarmee biedt het aan de amateur-elektronicus, technicus, zendamateur en andere radio-enthousiasten het noodzakelijke materiaal om zich verder te bekwamen op dit gebied. Er wordt slechts weinig aandacht besteed aan de theorie, maar dat heeft een groot voordeel: ruim 300 pagina’s vol praktijk. De zenders, sommige eenvoudig, andere meer gecompliceerd, werden speciaal ontworpen voor het gebruik door amateurs. Ze werken tussen 150 kHz en 1300 MHz. De gebruikte techniek dateert vooral uit de jaren 90. Dit mag op het eerste gezicht een tekortkoming lijken, maar het is juist een extra argument voor publicatie. De technieken hebben zich inmiddels bewezen en er worden eenvoudige, goedkope en nog steeds goed verkrijgbare onderdelen gebruikt. Dit boek richt zich dus in de eerste plaats tot de potentiële gebruiker van HF-technieken, die er niet voor terugschrikt om dit soort schakelingen in elkaar te zetten. De schakelingen zijn probleemloos na te bouwen (nog een voordeel van zich bewezen technieken). Om dat te bereiken hebben de auteurs veel aandacht besteed aan: de testprocedures voor elke schakeling, de onderdelenlijst, instructies voor het vervaardigen van de spoelen en voor de afregeling. Bij de meeste schakelingen is bovendien een printontwerp afgedrukt. Naast zenders voor o.a. FM-stereo, AM, VHF-FM-amateur, R/C-TV, 40-m-CW-zender, 10-m-SSB, 2-m-NBFM, FM-video-link en amateur-TV vindt u in dit boek ook verwante schakelingen, zoals een down-converter voor 400, 900 en 1300 MHz en een HF-vermogensmeter.

En moins de 100 lignes de code par projet avec les cartes Feather Sense et Clue Express d'Adafruit 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)
