Eine praktische Einführung in Architektur, Peripherie und eingebettete Programmierung.Neu und groß im Kommen – RISC-V ist eine auf freier Technologie basierende Befehlssatzarchitektur. In Anwendung im ESP32-C3-DevKitM-1 werden hier grundlegende Konzepte und Funktionsweisen von Mikrocontrollern theoretisch vermittelt.Mehrere Hands-On-Projekte dienen außerdem dazu, Ihnen einen ersten Einblick zu geben, Sie für das selbstständige Programmieren mit Mikrocontrollern vorzubereiten und das Gelernte Schritt für Schritt zu vertiefen.Das Werk ist in drei Teile gegliedert, welche aufeinander aufbauen. Teil eins geht auf den Aufbau eines RISC-V-Mikroprozessors und die hardwarenahe Programmierung ein. Hierbei werden den Leser:innen wichtige Grundlagen mit auf den Weg gegeben. Der zweite Teil setzt den Fokus auf das Erlernen von elektrotechnischen Grundlagen und wie Peripheriemodule angesteuert werden. Im letzten Teil wird ein Pulsoximeter als Beispiel genommen, wie verschiedene Internetprotokolle funktionieren. Eine praktische Betrachtung von Bluetooth LE rundet diesen Teil ab.Über den Autor:Prof.(FH) Dipl-Ing. Patrick Ritschel studierte Informatik an der TU Wien.

* ALLE PYTHON-GRUNDLAGEN FÜR DIE PROGRAMMIERUNG DES RASPBERRY PI 4* PROJEKTE MIT SENSOREN, RELAIS UND AD-WANDLERN* EINSATZ VON PERIPHERIEGERÄTEN WIE KAMERAMODUL UND LAUTSPRECHERDer Raspberry Pi ist ein preiswerter und äußerst energiesparsamer Computer in der Größe einer Kreditkarte. In Kombination mit der Programmiersprache Python bietet er eine hervorragende Umgebung für die schnelle Realisierung technischer Ideen und Projekte. Außerdem ist Python – auch für Programmiereinsteiger – einfach zu lernen und deshalb Teil des Gesamtkonzepts des Raspberry Pi. Dieses Buch vermittelt Ihnen anhand vieler anschaulicher Beispiele sowohl die Grundlagen von Python als auch fortgeschrittene Techniken wie Objektorientierung, Internetprogrammierung und grafische Benutzungsoberflächen.Nach dem Erlernen der Programmierkonzepte finden Sie besonders in der zweiten Hälfte des Buches eine Fülle von kleinen Projekten, die auf die besondere Hardware des Raspberry Pi und das Linux-Betriebssystem Raspberry Pi OS zugeschnitten sind. Zur Vorbereitung jedes Projekts werden zunächst neue Elemente der Python-Programmierung eingeführt. Zahlreiche Illustrationen und einfache Beispiele zum Ausprobieren erleichtern das Verständnis.Zu den vielfältigen Projekten im Buch gehören Schaltungen mit Sensoren (Temperatur, Licht, Kohlendioxid, Alkohol), Relais, AD-Wandlern und LEDs. Sie erfahren, wie man Peripheriegeräte wie das Kameramodul anschließt und den 1-Wire- sowie den SPI-Bus zur Datenkommunikation nutzt.Am Ende jedes Kapitels finden Sie Aufgaben und Lösungen, mit denen Sie Ihr Wissen festigen, erweitern und vertiefen können.AUS DEM INHALT:* Namen und Zuweisungen* Kontrollstrukturen* Kollektionen: Mengen, Listen, Tupel, Dictionaries* Verarbeitung von Strings* Funktionen* Grafische Benutzungsoberflächen* Dateien und Ressourcen aus dem Internet* Zeitfunktionen und Threads* Objektorientierte Programmierung* Webserver und CGI-Skripte* Einsatz von DatenbankenPROJEKTE MIT DEM RASPBERRY PI:* Gerätesteuerung* Messwerterfassung und -visualisierung* Interaktive Spiele* Animationen und Simulationen* Automatische Textproduktion und Editoren* Digitale Bildverarbeitung* Morsezeichen senden und Signalmuster erkennen* Projekte mit OLED und Sense HAT* Farben und Bewegung wahrnehmen* Steuerung mit Potenziometer und AD-Wandler* Auswertung von Daten aus dem Internet* Webserver und interaktive WebcamMichael Weigend hat an der Universität Potsdam in Informatik promoviert.
