GNU/Linux Rapid Embedded Programming oleh Rodolfo Giometti

Key FeaturesRapidly design and build powerful prototypes for GNU/Linux Embedded systemsBecome familiar with the workings of GNU/Linux Embedded systems and how to manage its peripheralsWrite, monitor, and configure applications quickly and effectively, manage an external micro-controller, and use it as co-processor for real-time tasksBook DescriptionEmbedded computers have become very complex in the last few years and developers need to easily manage them by focusing on how to solve a problem without wasting time in finding supported peripherals or learning how to manage them. The main challenge with experienced embedded programmers and engineers is really how long it takes to turn an idea into reality, and we show you exactly how to do it. This book shows how to interact with external environments through specific peripherals used in the industry. We will use the latest Linux kernel release 4.4.x and Debian/Ubuntu distributions (with embedded distributions like OpenWrt and Yocto).The book will present popular boards in the industry that are user-friendly to base the rest of the projects on - BeagleBone Black, SAMA5D3 Xplained, Wandboard and system-on-chip manufacturers.Readers will be able to take their first steps in programming the embedded platforms, using C, Bash, and Python/PHP languages in order to get access to the external peripherals. More about using and programming device driver and accessing the peripherals will be covered to lay a strong foundation. The readers will learn how to read/write data from/to the external environment by using both C programs or a scripting language (Bash/PHP/Python) and how to configure a device driver for a specific hardware.After finishing this book, the readers will be able to gain a good knowledge level and understanding of writing, configuring, and managing drivers, controlling and monitoring applications with the help of efficient/quick programming and will be able to apply these skills into real-world projects.What you will learnUse embedded systems to implement your projectsAccess and manage peripherals for embedded systemsProgram embedded systems using languages such as C, Python, Bash, and PHPUse a complete distribution, such as Debian or Ubuntu, or an embedded one, such as OpenWrt or YoctoHarness device driver capabilities to optimize device communicationsAccess data through several kinds of devices such as GPIOs, serial ports, PWM, ADC, Ethernet, WiFi, audio, video, I2C, SPI, One Wire, USB and CANPractical example usage of several devices such as RFID readers, Smart card readers, barcode readers, z-Wave devices, GSM/GPRS modemsUsage of several sensors such as light, pressure, moisture, temperature, infrared, power, motionAbout the AuthorRodolfo Giometti is an engineer, IT specialist, GNU/Linux expert and software libre evangelist.Author of the books BeagleBone Essentials and BeagleBone Home Automation Blueprints by Packt Publishing and maintainer of the LinuxPPS projects (the Linuxs Pulse Per Second subsystem) he still actively contributes to the Linux source code with several patches and new device drivers for industrial applications devices.During his twenty-year+ experience, he, worked with x86, ARM, MIPS, & PowerPC-based platform.Now, Rodolfo is the Co-Chief at HCE Engineering S.r.l. and he is the Co-Founder of the Cosino Project, which involves new hardware and software systems for the quick prototyping in industry environment, control automation, and remote monitoring.Table of ContentsInstalling the Developing SystemManaging the System ConsoleC Compiler, Device Drivers, and Useful Developing TechniquesQuick Programming with Scripts and System DaemonsSetting Up an Embedded OSGeneral Purposes Input Output signals – GPIOSerial Ports and TTY Devices - TTYUniversal Serial Bus - USBInter-Integrated Circuits - I2CSerial Peripheral Interface - SPI1-Wire - W1Ethernet Network Device - ETHWireless Network Device - WLANController Area Network - CANSound Devices - SNDVideo devices - V4LAnalog-to-Digital Converters - ADCPulse-Width Modulation - PWMMiscellaneous Devices
