A Guide to Powerful Programming for Embedded Systems You must be a well-rounded professional to excel in the ever-evolving, rapidly developing embedded design and programming industry. Simply put, when it comes to electronics design and programming, the more topics you can master, the more you’ll flourish at your workplace and at your personal workbench. This shouldn’t be a surprise, as the line between the skills of a hardware engineer and software engineer is blurring. The former should have a good grasp of programming in order to build efficient systems. The latter should understand the details of the design (whether it’s a physical or virtual application) for which he or she is writing code. Thus, to be successful, a modern professional electronics engineer must have a solid grasp of both hardware design and programming. Assembly Language Essentials is a matter-of-fact guide to Assembly that will introduce you to the most fundamental programming language of a processor. Unlike other resources about Assembly that focus exclusively on specific processors and platforms, this book uses the architecture of a fictional processor with its own hardware and instruction set. This enables you to consider the importance of Assembly language without having to deal with predetermined hardware or architectural restrictions. You’ll immediately find this thorough introduction to Assembly to be a valuable resource, whether you know nothing about the language or you have used it before. The only prerequisite is that you have a working knowledge of at least one higher-level programming language, such as C or Java. Assembly Language Essentials is an indispensible resource for electronics engineering professionals, academics, and advanced students looking to enhance their programming skills. The book provides the following, and more: An introduction to Assembly language and its functionality Significant definitions associated with Assembly language, as well as essential terminology pertaining to higher-level programming languages and computer architecture Important algorithms that may be built into high-level languages, but must be done the “hard way” in Assembly language — multiplication, division, and polynomial evaluation A presentation of Interrupt Service Routines with examples A free, downloadable Assembler program for experimenting with Assembly

Technology is constantly changing. New microcontrollers become available every year and old ones become redundant. The one thing that has stayed the same is the C programming language used to program these microcontrollers. If you would like to learn this standard language to program microcontrollers, then this book is for you! ARM microcontrollers are available from a large number of manufacturers. They are 32-bit microcontrollers and usually contain a decent amount of memory and a large number of on-chip peripherals. Although this book concentrates on ARM microcontrollers from Atmel, the C programming language applies equally to other manufacturer’s ARMs as well as other microcontrollers. Features of this book Use only free or open source software. Learn how to download, set up and use free C programming tools. Start learning the C language to write simple PC programs before tackling embedded programming - no need to buy an embedded system right away! Start learning to program from the very first chapter with simple programs and slowly build from there. No programming experience is necessary! Learn by doing - type and run the example programs and exercises. Sample programs and exercises can be downloaded from the Internet. A fun way to learn the C programming language. Ideal for electronic hobbyists, students and engineers wanting to learn the C programming language in an embedded environment on ARM microcontrollers.

Microcontrollers have become an indispensable part of modern electronics. They make things possible that vastly exceed what could be done previously. Innumerable applications show that almost nothing is impossible. There’s thus every reason to learn more about them, but that raises the question of where to find a good introduction to this fascinating technology. The answer is easy: this Microcontroller Basics book, combined with the 89S8252 Flash Board project published by Elektor Electronics. However, this book offers more than just a basic introduction. It clearly explains the technology using various microcontroller circuits and programs written in several different programming languages. Three microcontrollers from the 8051 family are used in the sample applications, ranging from the simple 89C2051 to the AN2131, which is designed to support USB applications. The programming tools include assemblers, Basic-52 and BASCOM-51, and several C compilers. Every reader can thus find the programming environment most suitable to his or her needs. In the course of the book, the reader gradually develops increased competence in converting his or her ideas into microcontroller circuitry. All of the sample programs can be downloaded from the Elektor Electronics website or the author’s website. That has the added advantage that the latest versions are always available.

RFID technology has conquered many areas in which barcodes, magnetic strips and contact smartcards were used previously. Everyday applications, such as electronic ticketing, access cards, debit cards and electronic identity documents would not be possible without this technology. MIFARE is the most widely used RFID technology, and this book provides a practical and comprehensive introduction to it. Among other things, the initial chapters cover physical fundamentals, relevant standards, RFID antenna design, security considerations and cryptography. The complete design of a reader’s hardware and software is described in detail. The reader’s firmware and the associated PC software support programming using any .NET language. The specially developed PC program, “Smart Card Magic.NET”, is a simple development environment that supports sending commands to a card at the click of a mouse, as well as the ability to create C# scripts. Alternatively, one may follow all of the examples using Visual Studio 2010 Express Edition. Finally, the major smart card reader API standards are introduced. The focus is on programming contactless smartcards using standard PC/SC readers using C/C++, Java and C#.

Resonances From Aether Days A Pictorial and Technical Analysis from WWII to the Internet Age From the birth of radio to the late 1980s, much of real life unfolded through shortwave communication. World War II demonstrated—beyond a shadow of a doubt—that effective communications equipment was a vital prerequisite for military success. In the postwar years, shortwave became the backbone on which many of the world's most critical services depended every day. All the radio equipment—through whose cathodes, grids, plates, and transistors so much of human history has flowed—is an exceptional subject of study and enjoyment for those of us who are passionate about vintage electronics. In this book, which begins in the aftermath of World War II, you’ll find a rich collection of information: descriptions, tips, technical notes, photos, and schematics that will be valuable for anyone interested in restoring—or simply learning about—these extraordinary witnesses to one of the most remarkable eras in technological history. My hope is that these pages will help preserve this vast treasure of knowledge, innovation, and history—a heritage that far transcends the purely technical.

20+ Macintosh Models, from 1984 to Today (History, Engineering, and Restoration) Apple is not like any other company. More than anyone else, it transformed technology into something people could desire, love, and even identify with—much like a luxury brand. Users were not only buying a tool; they were buying a vision, a way of life. At the center of this transformation stands the Macintosh. First introduced in 1984, it was radically different from everything before. With its graphical interface and mouse, it made computing approachable, even friendly. What now feels obvious—clicking on icons, dragging files, pointing instead of typing commands—was revolutionary at the time. The Macintosh not only changed the way people related to technology. The Macintosh forced the entire industry to rethink the way we use computers. This book tells that story through some of the most significant Macintosh models. Each one is presented not only in words but also in images, because these computers are more than technology—they are design icons, symbols of a unique vision. History, technical detail, and photography come together here, aiming to show each Macintosh as it truly deserves to be seen.
