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.

Develop innovative hardware-based projects in C
The Raspberry Pi has traditionally been programmed using Python. Although this is a very powerful language, many programmers may not be familiar with it. C on the other hand is perhaps the most commonly used programming language and all embedded microcontrollers can be programmed using it.
The C language is taught in most technical colleges and universities and almost all engineering students are familiar with using it with their projects. This book is about using the Raspberry Pi with C to develop a range of hardware-based projects. Two of the most popular C libraries, wiringPi and pigpio are used.
The book starts with an introduction to C and most students and newcomers will find this chapter invaluable. Many projects are provided in the book, including using Wi-Fi and Bluetooth to establish communication with smartphones.
Many sensor and hardware-based projects are included. Both wiringPi and pigpio libraries are used in all projects. Complete program listings are given with full explanations. All projects have been fully tested and work.
The following hardware-based projects are provided in the book:
Using sensors
Using LCDs
I²C and SPI buses
Serial communication
Multitasking
External and timer interrupts
Using Wi-Fi
Webservers
Communicating with smartphones
Using Bluetooth
Sending data to the cloud
Program listings of all Raspberry Pi projects developed in this book are available on the Elektor website. Readers can download and use these programs in their projects. Alternatively, they can customize them to suit their applications.

Elektronische Systeme in Fahrzeugen werden immer wichtiger. Dies ist nicht nur auf die gestiegenen Ansprüche der Kunden hinsichtlich Komfort und Sicherheit zurückzuführen: Auch der Umweltschutz spielt bei dieser Entwicklung eine entscheidende Rolle. Aufgrund dieser Tatsache befinden sich heutzutage bis zu 80 elektronische Regeleinheiten in unseren Fahrzeugen, die – auch wenn sie von verschiedenen Herstellern stammen – natürlich auch miteinander kommunizieren müssen.Seit 2008 verlangt die europäische Gesetzgebung bei neu zugelassenen Fahrzeugen, dass sich Störungen, die zu einem erhöhten Schadstoffausstoß führen, über den CAN-Bus mit einem externen Diagnosetester aufspüren lassen.In diesem Buch werden Funktion und Aufbau des CAN-Protokolls sowohl im Hard- als auch im Software-Bereich ausführlich beschrieben. Dabei kommen die damit verbundenen Themen wie „Aufbau eines CAN-Berichtes“, „Prioritätsregelung“ und „physikalische Verbindung“ nicht zu kurz. Neben dem CAN-Bus ist EOBD-via-CAN ein vorherrschendes Thema. Wie funktioniert EOBD und welche diagnostischen Gegebenheiten sind mithilfe eines Diagnosetesters zugänglich?Die Gesetzgebung der Europäischen Union und die internationalen ISO- und SAE-Normen führen den Leser wie ein roter Faden durch die einzelnen Kapitel. Alle mit dem Thema in Zusammenhang stehenden Gesetze tragen zu einer Verringerung der Umweltbelastung bei und sorgen dafür, dass eine emissionsbezogene Störung am Fahrzeug schnell angezeigt (und damit auch repariert) wird.Ganz gleich, ob es um das Verständnis eines CAN-Berichtes, um das Aufspüren eines lästigen Fehlers oder gar um den Aufbau eines eigenen CAN-Bus-Systems geht: Dieses Buch erklärt nicht nur den CAN-Bus, sondern auch die Diagnose mittels CAN-Bus in verständlicher Weise und ist für private „Schrauber“ und professionelle Diagnosetechniker gleichermaßen geeignet. Studenten und Entwickler von CAN- und EOBD-Applikationen können sich mit diesem Buch durch „Probieren und Studieren“ eine Basis für ihre eigenen Entwicklungen schaffen.

A Combat Guide against E-waste and Throwawayism
This book is for anyone who enjoys tinkering with analog and digital hardware electronics. Regardless of the sophistication of your workspace, only basic tools are required to achieve truly satisfying results. It is intended as a reference guide among other hardware repair publications you may have in your library. However, the book goes a step further than most other repair guides in addressing issues in the modern era of discarded electronics called e-waste.
E-waste should be put to good use. Producing anything new requires not just precious resources and labor, but also energy to make and deliver it to global retail shelves. Your talents and love of electronics can be put to good use by rescuing and resurrecting at least selected units from this endless stream of e-waste. Examples include either restoring through repair, or salvaging reusable electronic and mechanical components for your next project.
Smart tips are provided throughout the book, and much information is tabulated for easy reference. The book expands age-old repair and hacking techniques applied for repair on the workbench into clever methods and applications to achieve effective results with discarded or “non-servicable” electronic consumer products. The final chapter provides real-life examples using all of the previously discussed content in a summarized form for each example repair type.

The Raspberry Pi is a powerful computer in a small package, with lots of interfacing options to control various devices. This book shows you how you can automate your home with a Raspberry Pi. You’ll learn how to use various wireless protocols for home automation, such as Bluetooth, 433.92 MHz radio waves, Z-Wave, and Zigbee. Soon you’ll automate your home with Python, Node-RED, and Home Assistant, and you’ll even be able to speak to your home automation system. All this is done securely, with a modular system, completely open-source, without relying on third-party services. You’re in control of your home, and no one else.
At the end of this book, you can install and configure your Raspberry Pi as a highly flexible home automation gateway for protocols of your choice, and link various services with MQTT to make it your own system. This DIY (do it yourself) approach is a bit more laborious than just installing an off-the-shelf home automation system, but in the process, you can learn a lot, and in the end, you know exactly what’s running your house and how to tweak it. This is why you were interested in the Raspberry Pi in the first place, right?
Turn your Raspberry Pi into a reliable gateway for various home automation protocols.
Make your home automation setup reproducible with Docker Compose.
Secure all your network communication with TLS.
Create a video surveillance system for your home.

The Controller Area Network (CAN) was originally developed to be used as a vehicle data bus system in passenger cars. Today, CAN controllers are available from over 20 manufacturers, and CAN is finding applications in other fields, such as medical, aerospace, process control, automation, and so on.
This book is written for students, for practising engineers, for hobbyists, and for everyone else who may be interested to learn more about the CAN bus and its applications.
The aim of this book is to teach you the basic principles of CAN networks and in addition the development of microcontroller based projects using the CAN bus. In summary, this book enables the reader to:
Learn the theory of the CAN bus used in automotive industry
Learn the principles, operation, and programming of microcontrollers
Design complete microcontroller based projects using the C language
Develop complete real CAN bus projects using microcontrollers
Learn the principles of OBD systems used to debug vehicle electronics
You will learn how to design microcontroller based CAN bus nodes, build a CAN bus, develop high-level programs, and then exchange data in real-time over the bus. You will also learn how to build microcontroller hardware and interface it to LEDs, LCDs, and A/D converters.
The book assumes that the reader has some knowledge on basic electronics. Knowledge of the C programming language will be useful in later chapters of the book, and familiarity with at least one member of the PIC series of microcontrollers will be an advantage, especially if the reader intends to develop microcontroller based projects using the CAN bus.
