With the availability of free and open source C/C++ compilers today, you might wonder why someone would be interested in assembler language. What is so compelling about the RISC-V Instruction Set Architecture (ISA)? How does RISC-V differ from existing architectures? And most importantly, how do we gain experience with the RISC-V without a major investment? Is there affordable hardware available? The availability of the Espressif ESP32-C3 chip provides a way to get hands-on experience with RISC-V. The open sourced QEMU emulator adds a 64-bit experience in RISC-V under Linux. These are just two ways for the student and enthusiast alike to explore RISC-V in this book. The projects in this book are boiled down to the barest essentials to keep the assembly language concepts clear and simple. In this manner you will have “aha!” moments rather than puzzling about something difficult. The focus in this book is about learning how to write RISC-V assembly language code without getting bogged down. As you work your way through this tutorial, you’ll build up small demonstration programs to be run and tested. Often the result is some simple printed messages to prove a concept. Once you’ve mastered these basic concepts, you will be well equipped to apply assembly language in larger projects.

Program and Build Raspberry Pi 5 Based Ham Station Utilities with the RTL-SDR The RTL-SDR devices (V3 and V4) have gained popularity among radio amateurs because of their very low cost and rich features. A basic system may consist of a USB based RTL-SDR device (dongle) with a suitable antenna, a Raspberry Pi 5 computer, a USB based external audio input-output adapter, and software installed on the Raspberry Pi 5 computer. With such a modest setup, it is possible to receive signals from around 24 MHz to over 1.7 GHz. This book is aimed at amateur radio enthusiasts and electronic engineering students, as well as at anyone interested in learning to use the Raspberry Pi 5 to build electronic projects. The book is suitable for both beginners through experienced readers. Some knowledge of the Python programming language is required to understand and eventually modify the projects given in the book. A block diagram, a circuit diagram, and a complete Python program listing is given for each project, alongside a comprehensive description. The following popular RTL-SDR programs are discussed in detail, aided by step-by-step installation guides for practical use on a Raspberry Pi 5: SimpleFM GQRX SDR++ CubicSDR RTL-SDR Server Dump1090 FLDIGI Quick RTL_433 aldo xcwcp GPredict TWCLOCK CQRLOG klog Morse2Ascii PyQSO Welle.io Ham Clock CHIRP xastir qsstv flrig XyGrib FreeDV Qtel (EchoLink) XDX (DX-Cluster) WSJT-X The application of the Python programming language on the latest Raspberry Pi 5 platform precludes the use of the programs in the book from working on older versions of Raspberry Pi computers.

Projects with Thonny-IDE, uPyCraft-IDE, and ESP32 The 'Python' programming language has enjoyed an enormous upswing in recent years. Not least, various single-board systems such as the Raspberry Pi have contributed to its popularity. But Python has also found widespread use in other fields, such as artificial intelligence (AI) or machine learning (ML). It is obvious, therefore, to use Python or the 'MicroPython' variant for use in SoCs (Systems on Chip) as well. Powerful controllers such as the ESP32 from Espressif Systems offer excellent performance as well as Wi-Fi and Bluetooth functionality at an affordable price. With these features, the Maker scene has been taken by storm. Compared to other controllers, the ESP32 has a significantly larger flash and SRAM memory, as well as a much higher CPU speed. Due to these characteristics, the chip is not only suitable for classic C applications, but also for programming with MicroPython. This book introduces the application of modern one-chip systems. In addition to the technical background, the focus is on MicroPython itself. After the introduction to the language, the programming skills learned are immediately put into practice. The individual projects are suitable for use in the laboratory as well as for everyday applications. So, in addition to the actual learning effect, the focus is also on the joy of building complete and useful devices. By using laboratory breadboards, circuits of all kinds can be realized with little effort, turning the testing and debugging of the 100% homebrew projects into an instructive pleasure. The various applications, such as weather stations, digital voltmeters, ultrasound range finders, RFID card readers or function generators, make the projects presented ideally suited for practical courses or subject and study work in the natural sciences, or in science and technology classes.

This book is for people who want to understand how AC drives (also known as inverter drives) work and how they are used in industry by showing mainly the practical design and application of drives. The key principles of power electronics are described and presented in a simple way, as are the basics of both DC and AC motors. The different parts of an AC drive are explained, together with the theoretical background and the practical design issues such as cooling and protection. An important part of the book gives details of the features and functions often found in AC drives and gives practical advice on how and where to use these. Also described is future drive technology, including a matrix inverter. The mathematics is kept to an essential minimum. Some basic understanding of mechanical and electrical theory is presumed, and a basic knowledge of single andthree phase AC systems would be useful. Anyone who uses or installs drives, or is just interested in how these powerful electronic products operate and control modern industry, will find this book fascinating and informative.

Het boek beschrijft de werking van digitale circuits vanaf schakelingen met poorten tot aan de werking van een processor. Van elke schakeling of systeem kan de werking worden gesimuleerd. Hierbij wordt het gedrag van componenten en het verloop van signalen in de tijd op ingangen, uitgangen en relevante verbindingslijnen zichtbaar gemaakt. Zo wordt in detail gevisualiseerd wat het gedrag is van de hardware als er een instructie wordt uitgevoerd. Het boek is opgebouwd uit drie modules die de volgende onderwerpen behandelen: Basismodule Poorten en combinatorische schakelingen. Hoe rekent een computer? Hoe werkt een rekenmachine? Module Digitale Techniek Hoe ontwerp je combinatorische schakelingen m.b.v. Boole-algebra? Sequentiële schakelingen en het ontwerpen van ‘Finite State Systems’. Complexe schakelingen als decoders, multiplexers, asynchrone en synchrone tellers. Module Computerarchitectuur Hoe werkt een ‘loopje’ precies? If-then-else, while en for loops. De Harvard-architectuur. Hoe verloopt de communicatie tussen de aanroeper en de aangeroepene bij aanroep van een procedure? Bij de module Computerarchitectuur worden programma’s in de taal assembler geschreven. Hierbij wordt gebruik gemaakt van een instructieset van slechts 15 instructies. Website Het boek wordt ondersteund door de website: www.science.uva.nl/amstel/SIM-PL. De SIM-PL software en de componenten die nodig zijn voor de simulaties kunnen hiervandaan worden gedownload. Ook staan hier antwoorden op vragen en vraagstukken. Verder zijn op deze site collegesheets voor docenten en voorbeelden van tentamens beschikbaar. Doelgroepen VAN 0 EN 1 TOT PROCESSOR is geschreven voor iedereen die geïnteresseerd is in de basisprincipes waarop de werking van computers berust. Het boek is zeer geschikt voor studenten Informatica, Technische Informatica en E-technology in het hoger onderwijs en het MBO.
