An Introduction to RISC-V RISC-V is an Instruction Set Architecture (ISA) that is both free and open. This means that the RISC-V ISA itself does not require a licensing fee, although individual implementations may do so. The RISC-V ISA is curated by a non-profit foundation with no commercial interest in products or services that use it, and it is possible for anyone to submit contributions to the RISC-V specifications. The RISC-V ISA is suitable for applications ranging from embedded microcontrollers to supercomputers. This book will first describe the 32-bit RISC-V ISA, including both the base instruction set as well as the majority of the currently-defined extensions. The book will then describe, in detail, an open-source implementation of the ISA that is intended for embedded control applications. This implementation includes the base instruction set as well as a number of standard extensions. After the description of the CPU design is complete the design is expanded to include memory and some simple I/O. The resulting microcontroller will then be implemented in an affordable FPGA development board (available from Elektor) along with a simple software application so that the reader can investigate the finished design.

Die Kurzwellentechnik übt einen ganz besonderen Reiz aus. Man kann mit geringstem Aufwand große Entfernungen überbrücken. Durch Reflexion an leitenden Schichten der Ionosphäre und am Boden werden Kurzwellensignale auch an Orten jenseits des Horizonts hörbar. So lässt sich jeder Ort auf der Erde erreichen. Zwar strebt die Technik nach immer höheren Frequenzen, und Radio hört man meist auf UKW, über DAB+, über Satellit oder das Internet. Aber alle diese moderneren Übertragungswege benötigen eine umfangreiche Infrastruktur und sind extrem verletzlich. Im Falle eines globalen Stromausfalls geht nichts mehr außer auf der Kurzwelle. Deshalb wird im Amateurfunk nicht nur ein Hobby gepflegt, sondern auch ein Notfunksystem aufrechterhalten. Das Elektor SDR-Shield ist ein vielseitiger Kurzwellenempfänger bis 30 MHz. Zusammen mit einem Arduino-Board und der passenden Software lassen sich nicht nur Rundfunkstationen empfangen, sondern auch Morsesignale, SSB-Stationen und digitale Signale. Der Erfolgsautor und begeisterter Amateurfunker Burkhard Kainka beschreibt im vorliegenden Buch die moderne Praxis des Software Defined Radios mithilfe des Elektor SDR-Shields. Dabei vermittelt er nicht nur den theoretischen Background, sondern erklärt auch zahlreiche Software-Werkzeuge aus dem Open-Source-Bereich, die heute die Kurzwellentechnik zu einem absolut spannenden und hochmodernen Hobby machen.

It is becoming important for microcontroller users to quickly learn and adapt to new technologies and architecture used in high performance 32-bit microcontrollers. Many manufacturers now offer 32-bit microcontrollers as general purpose processors in embedded applications. ARM provide 32 and 64-bit processors mainly for embedded applications. These days, the majority of mobile devices including mobile phones, tablets, and GPS receivers are based on ARM technology. The low cost, low power consumption, and high performance of ARM processors makes them ideal for use in complex communication and mixed signal applications. This book makes use of the ARM Cortex-M family of processors in easy-to-follow, practical projects. It gives a detailed introduction to the architecture of the Cortex-M family. Examples of popular hardware and software development kits are described. The architecture of the highly popular ARM Cortex-M processor STM32F107VCT6 is described at a high level, taking into consideration its clock mechanisms, general input/output ports, interrupt sources, ADC and DAC converters, timer facilities, and more. The information provided here should act as a basis for most readers to start using and programming the STM32F107VCT6 microcontroller together with a development kit. Furthermore, the use of the mikroC Pro for ARM integrated development environment (IDE) has been described in detail. This IDE includes everything required to create a project; namely an editor, compiler, simulator, debugger, and device programmer. Although the book is based on the STM32F107VCT6 microcontroller, readers should not find it difficult to follow the projects using other ARM processor family members.

This book is about advanced programming of the Raspberry Pi computer using the Python programming language. The book explains in simple terms and with examples: How to configure the Raspberry Pi computer; How to install and use the Linux operating system and the desktop; How to write advanced programs using the Python programming language; How to use graphics in our programs; How to develop hardware based projects using the Raspberry Pi. The book starts with an introduction to the Raspberry Pi computer and covers the topics of purchasing all the necessary accessories and installing and operating the Linux operating system in command mode. The network interface of the RPi is explained in simple steps, demonstrating how the computer can be accessed remotely from a desktop or a laptop computer. The remaining parts of the book cover the Python programming language in detail, including advanced topics such as operating system calls, multitasking, interprocess synchronization and interprocess communication techniques. The important topic of network programming using UDP and TCP protocols is described with working examples. The Tkinter graphical user interface module (GUI) is described in detail with example widgets and programs. The last part of the book includes hardware projects based on using the advanced programming topics such as multitasking and interprocess communication techniques. All the projects given in the book have been fully tested and are working. Complete program listings of all projects are provided with detailed explanations.
