Mit RPi-basierten Tools und Messgeräten Amateurfunkstationen bauen und programmieren Obwohl viele Funkamateure immer noch mit klassischer HF- und Mobilfunkausrüstung arbeiten, ist der Einsatz von Computern und digitalen Techniken inzwischen sehr beliebt. Heutzutage kann jeder für ca. 40 € einen Raspberry Pi-Computer kaufen und fast jede Amateurfunk-Software auf dem 'RPi' ausführen. Die RTL-SDR-Geräte sind bei Funkamateuren sehr beliebt, weil sie sehr preiswert sind und viele Funktionen bieten. Ein Basissystem kann aus einem USB-basierten RTL-SDR-Dongle mit einer geeigneten Antenne, einem RPi-Computer, einem USB-basierten externen Audio-Eingangs-/ Ausgangsadapter und einer auf dem RPi installierten Software bestehen. Mit einer solch einfachen Einrichtung ist es möglich, Signale von etwa 24 MHz bis über 1,7 GHz zu empfangen. Dieses Buch richtet sich an Funkamateure, die lernen wollen, wie man mit dem Raspberry Pi elektronische Projekte baut. Das Buch eignet sich für die gesamte Bandbreite von Anfängern bis hin zu alten Hasen im Amateurfunk. Die schrittweise Installation des Betriebssystems wird mit vielen Details zu den gängigsten Linux-Befehlen beschrieben. Einige Kenntnisse der Programmiersprache Python sind erforderlich, um die im Buch beschriebenen Projekte zu verstehen und zu bearbeiten. Zu den im Buch entwickelten Beispielprojekten gehören eine Stationsuhr, ein Signalgenerator, der Entwurf eines Transistorverstärkers, der Entwurf eines aktiven Filters, ein Morsezeichen-Übungsgerät, ein Frequenzzähler, ein HF-Meter und vieles mehr. Für jedes Projekt werden das Blockdiagramm, der Schaltplan und der vollständige Python-Quellcode angegeben, einschließlich der vollständigen Beschreibung der Projekte. Neben der umfassenden Behandlung von RTL-SDR für Amateurfunk fasst das Buch auch die Installations- und Gebrauchsanweisungen der folgenden Amateurfunkprogramme zusammen, die Sie auf ihrem Raspberry Pi ausführen können: TWCLOCK, Klog, Gpredict, FLDIGI, DIRE WOLF, xcwcp, QSSTV, LinPsk, Ham Clock, CHIRP, xastir und CQRLOG.

This book details the use of the ARM Cortex-M family of processors and the Arduino Uno in practical CAN bus based projects. Inside, it gives a detailed introduction to the architecture of the Cortex-M family whilst providing examples of popular hardware and software development kits. Using these kits helps to simplify the embedded design cycle considerably and makes it easier to develop, debug, and test a CAN bus based project. The architecture of the highly popular ARM Cortex-M processor STM32F407VGT6 is described at a high level by considering its various modules. In addition, the use of the mikroC Pro for ARM and Arduino Uno CAN bus library of functions are described in detail. This book is written for students, for practising engineers, for hobbyists, and for everyone else who may need to learn more about the CAN bus and its applications. The book assumes that the reader has some knowledge of basic electronics. Knowledge of the C programming language will be useful in later chapters of the book, and familiarity with at least one microcontroller will be an advantage, especially if the reader intends to develop microcontroller based projects using CAN bus. The book should be useful source of reference to anyone interested in finding an answer to one or more of the following questions: What bus systems are available for the automotive industry? What are the principles of the CAN bus? What types of frames (or data packets) are available in a CAN bus system? How can errors be detected in a CAN bus system and how reliable is a CAN bus system? What types of CAN bus controllers are there? What are the advantages of the ARM Cortex-M microcontrollers? How can one create a CAN bus project using an ARM microcontroller? How can one create a CAN bus project using an Arduino microcontroller? How can one monitor data on the CAN bus?
