This book is intended as a highly-practical guide for Hobbyists, Engineers and Scientists wishing to build measurement and control systems to be controlled by a local or remote Personal Computer running the Linux operating system. Both hardware and software aspects of designing typical embedded systems are covered in detail with schematics, code listings and full descriptions. Numerous examples have been designed to show clearly how straightforward it can be to create the interfaces between digital and analog electronics, with programming techniques for creating control software for both local and remote systems. Hardware developers will appreciate the variety of circuits, including a novel, low cost modulated wireless link and will discover how using Matlab® overcomes the need for specialist programming skills. Software developers will appreciate how a better understanding of circuits plus the freedom offered by Linux to directly control at the register level enables them to optimize related programs. There is no need to buy special equipment or expensive software tools in order to create embedded projects covered in this book. You can build such quality systems quickly using popular low-cost electronic components and free distributed or low-cost software tools. Some knowledge of basic electronics plus the very basics of C programming only is required. Many projects in this book are developed using Matlab® being a very popular worldwide computational tool for research in engineering and science. The book provides a detailed description of how to combine the power of Matlab® with practical electronics. With an emphasis on learning by doing, readers are encouraged by examples to program with ease; the book provides clear guidelines as to the appropriate programming techniques “on the fly”. Complete and well-documented source code is provided for all projects. If you want to learn how to quickly build Linux-based applications able to collect, process and display data on a PC from various analog and digital sensors, how to control circuitry attached to a computer, then even how to pass data via a network or control your embedded system wirelessly and more – then this is the book for you!

This book is all about building your own DIY home control system. It presents two innovative ways to assemble such a system: By recycling old PC hardware – possibly extending the life of an old PC, or by using Raspberry Pi. In both cases, the main system outlined in this book will consist of a computer platform, a wireless mains outlet, a controller and a USB webcam – All linked together by Linux. By using the Raspberry Pi in conjunction with Arduino (used as an advanced I/O system board), it is possible to construct a small, compact, embedded control system offering enhanced capacity for USB integration, webcams, thermal monitoring and communication with the outside world. The experience required to undertake the projects within this book are minimal exposure to PC hardware and software, the ability to surf the internet, burn a CD-ROM and assemble a small PCB.

Dit boek gaat over de Raspberry Pi, en over het programmeren in C. De programmeertaal C en het besturingssysteem Linux (Raspbian) passen uitstekend bij elkaar. Alles wat we nodig hebben om in C te programmeren wordt meegeleverd met het besturingssysteem van de Raspberry Pi. In dit boek leert u hoe C gebruikt wordt met de Raspberry Pi, en krijgt u een overzicht van de taal. WiringPi is een softwarebibliotheek voor de Raspberry Pi waarmee C hardware-uitbreidingen kan benaderen. Die bibliotheek wordt gebruikt om sensoren uit te lezen en om extra hardware aan te sturen. U gaat experimenteren met LED’s en schakelaars, met motoren, met geluid en met sensoren voor temperatuur, luchtdruk, en luchtvochtigheid. Met een Linux-systeem kunt u een webserver maken, inclusief interactieve websites met PHP en WiringPi. Daarom is ook een beknopt overzicht van HTML en PHP in het boek opgenomen. In de voorbeelden worden sensoren via het web uitgelezen en worden apparaten bestuurd. In het laatste voorbeeld wordt een temperatuurlogger gemaakt. Die meet elk kwartier de temperatuur. Een tabel met de meetwaarden kan via het web worden uitgelezen. Alle voorbeeldprogramma’s kunnen worden gedownload van de website van Elektor.

Programming the Finite State Machine with 8-Bit PICs in Assembly and C Andrew Pratt provides a detailed introduction to programming PIC microcontrollers, as well as a thorough overview of the Finite State Machine (FSM) approach to programming. Most of the book uses assembly programming, but do not be deterred. The FSM gives a structure to a program, making it easy to plan, write, and modify. The last two chapters introduce programming in C, so you can make a direct comparison between the two techniques. The book references the relevant parts of the Microchip datasheet as familiarity with it is the best way to discover detailed information. This book is aimed at Microsoft Windows and Linux users. To keep your costs to a minimum and to simplify the toolchain, specific applications are provided as a free download to enable you to use an FTDI serial lead as the programmer. The assembler used is the open-source "gpasm". All programming can be done in a text editor. There are detailed instructions on how to perform the necessary installations on Windows, Linux Debian, and derivatives such as Ubuntu and Fedora. For programming in C, Microchip's XC8 compiler is used from the command line. In addition to the programming applications, two serial read and serial write applications can be used for communicating with the PICs from a computer. A voltmeter project including practical instructions on building a circuit board from scratch is included. All theory is covered beforehand, including how to do integer arithmetic in assembly. Two PICs are covered: the PIC12F1822 and the PIC16F1823. Both can run at 32 MHz with an internal oscillator. You do not need to buy a factory-made development board and programmer. With relatively inexpensive parts including a serial lead, microcontroller, a few resistors, and LEDs, you can get started exploring embedded programming. Links Updated Programmer
