Die serielle Schnittstelle dient dem Datenaustausch zwischen Mikrocontrollern und Peripheriegeräten. Bei einer seriellen Datenübertragung werden die Bits nacheinander – also seriell – über eine Leitung übertragen. Das Wissen um diese seriellen Schnittstellen erweitert die Einsatzmöglichkeiten von Mikrocontrollern und Peripheriegeräten ungemein. In diesem Buch werden die Grundlagen der Kommunikation für die drei seriellen Schnittstellen I²C, SPI und 1-Wire vorgestellt. Anhand praxisnaher Beispiele werden die Schnittstellen anschaulich dargestellt und deren Einsatz verdeutlicht. Software- und Hardwarebeispiele, die man in diesem Buch finden kann, wurden in Assembler für PIC-Mikrocontroller von Microchip realisiert. Die verwendeten Algorithmen und Vorgehensweisen kann man aber auf beliebige Plattform übertragen. Um den Inhalt des Buches ansprechend zu gestalten, demonstriert der Autor den Buchinhalt an zwei Platinen. Mit diesen Platinen ist es möglich, die in diesem Buch beschriebenen Beispiele auszuprobieren und mit den Schnittstellen zu experimentieren. Beide Platinen basieren auf 8-bit-PIC-Mikrocontrollern von Microchip.

The newcomer to Microchip’s PIC microcontrollers invariably gets an LED to flash as their first attempt to master this technology. You can use just a simple LED indicator in order to show that your initial attempt is working, which will give you confidence to move forward. This is how the book begins — simple programs to flash LEDs, and eventually by stages to use other display indicators such as the 7-segment display, alphanumeric liquid crystal displays and eventually a colour graphic LCD. As the reader progresses through the book, bigger and upgraded PIC chips are introduced, with full circuit diagrams and source code, both in assembler and C. In addition, a small tutorial is included using the MPLAB programming environment, together with the EAGLE schematic and PCB design package to enable readers to create their own designs using the book’s many case studies as working examples to work from.

If you enjoy DIY electronics, projects, software and robots, you’ll find this book intellectually stimulating and immediately useful. With the right parts and a little guidance, you can build robot systems that suit your needs more than overpriced commercial systems can. 20 years ago, robots based on simple 8-bit processors and touch sensors were the norm. Now, it’s possible to build multi-core robots that can react to their surroundings with intelligence. Today’s robots combine sensor readings from accelerometers, gyroscopes and computer vision sensors to learn about their environments. They can respond using sophisticated control algorithms and they can process data both locally and in the cloud. This book, which covers the theory and best practices associated with advanced robot technologies, was written to help roboticists, whether amateur hobbyist or professional, take their designs to the next level. As will be seen, building advanced applications does not require extremely costly robot technology. All that is needed is simply the knowledge of which technologies are out there and how best to use each of them. Each chapter in this book will introduce one of these different technologies and discuss how best to use it in a robotics application. On the hardware side, we’ll cover microcontrollers, servos, and sensors, hopefully inspiring you to design your own awe-inspiring, next-generation systems. On the software side, we’ll cover programming languages, debugging, algorithms, and state machines. We’ll focus on the Arduino, the Parallax Propeller, Revolution Education PICAXE and projects I’ve with which I’ve been involved, including the TBot educational robot, the PropScope oscilloscope, the 12Blocks visual programming language, and the ViewPort development environment. In addition, we’ll serve up a comprehensive introduction to a variety of essential topics, including output (e.g. LEDs, servo motors), and communication technologies (e.g. infrared, audio), that you can use to develop systems that interact to stimuli and communicate with humans and other robots. To make these topics as accessible as possible, handy schematics, sample code and practical tips regarding building and debugging have been included. Hanno Sander Christchurch, New Zealand
