Biography/History:

Giometti Rodolfo: Rodolfo Giometti is an engineer, IT specialist, GNU/Linux expert and software libre evangelist. He is the author of the books BeagleBone Essentials, BeagleBone Home Automation Blueprints and GNU/Linux Rapid Embedded Programming by Packt Publishing and maintainer of the LinuxPPS projects. He still actively contributes to the Linux source code with several patches and new device drivers for industrial applications devices. During his 20+ years of experience, he has worked on the x86, ARM, MIPS, and PowerPC-based platforms. Now, he is the co-chief at HCE Engineering S. r. l. , where he designs new hardware and software systems for the quick prototyping in industry environment, control automation, and remote monitoring.

Summary:

An annotated guide to program and develop GNU/Linux Embedded systems quickly About This Book Rapidly design and build powerful prototypes for GNU/Linux Embedded systems Become familiar with the workings of GNU/Linux Embedded systems and how to manage its peripherals Write, monitor, and configure applications quickly and effectively, manage an external micro-controller, and use it as co-processor for real-time tasks Who This Book Is For This book targets Embedded System developers and GNU/Linux programmers who would like to program Embedded Systems and perform Embedded development. The book focuses on quick and efficient prototype building. Some experience with hardware and Embedded Systems is assumed, as is having done some previous work on GNU/Linux systems. Knowledge of scripting on GNU/Linux is expected as well. What You Will Learn Use embedded systems to implement your projects Access and manage peripherals for embedded systems Program embedded systems using languages such as C, Python, Bash, and PHP Use a complete distribution, such as Debian or Ubuntu, or an embedded one, such as OpenWrt or Yocto Harness device driver capabilities to optimize device communications Access data through several kinds of devices such as GPIO’s, serial ports, PWM, ADC, Ethernet, WiFi, audio, video, I2C, SPI, One Wire, USB and CAN Practical example usage of several devices such as RFID readers, Smart card readers, barcode readers, z-Wave devices, GSM/GPRS modems Usage of several sensors such as light, pressure, moisture, temperature, infrared, power, motion In Detail Embedded computers have become very complex in the last few years and developers need to be able to easily manage embedded computer projects by focusing on problem solving; they should not have to waste time finding supported peripherals or learning how to manage them. This book shows you how to interact with external environments through specific peripherals used in the industry. It focuses on the latest Linux kernel release 4 and Debian/Ubuntu distributions (with embedded distributions such as OpenWRT and Yocto). This book presents popular and user-friendly boards in the industry – such as Beaglebone Black, Atmel Xplained, Wandboard, and system-on-chip manufacturers – and lets you explore corresponding projects that make use of these boards. You will first program the embedded platforms using the C, Bash, and Python/PHP languages in order to get access to the external peripherals. You will gain ...
