Programming Embedded Systems. With C and GNU Development Tools. 2nd Edition (e-book) Katowice

If you have programming experience and a familiarity with C--the dominant language in embedded systems--Programming Embedded Systems, Second Edition is exactly what you need to get started with embedded software. This software is ubiquitous, hidden away inside our watches, DVD players, mobile phones, anti-lock brakes, and even a few toasters. The military uses embedded software to guide missiles, detect enemy aircraft, and pilot UAVs. Communication satellites, deep-space probes, and many medical instruments would have been nearly impossible to create without embedded software.The first edition of Programming Embedded Systems taught the subject to tens of thousands ofpeople around the world and is now considered the bible of embedded programming. This second edition has been updated to cover all the latest hardware designs and development methodologies.The techniques and code examples presented here are directly applicable to real-world embedded software projects of all sorts. Examples use the free GNU software programming tools, the eCos and Linux operating systems, and a low-cost hardware platform specially developed for this book. If you obtain these tools along withProgramming Embedded Systems, Second Edition, you'll have a full environment for exploring embedded systems in depth. But even if you work with different hardware and software, the principles covered in this bookapply.Whether you are new to embedded systems or have done embedded work before, you'll benefit from the topics in this book, which include:How building and loading programs differ from desktop or servercomputersBasic debugging techniques--a critical skill when working withminimally endowed embedded systemsHandling different types of memoryInterrupts, and the monitoring and control of on-chip and externalperipheralsDetermining whether you have real-time requirements, and whetheryour operating system and application can meet those requirementsTask synchronization with real-time operating systems and embeddedLinuxOptimizing embedded software for size, speed, and power consumptionWorking examples for eCos and embedded LinuxSo whether you're writing your first embedded program, designing thelatest generation of hand-held whatchamacalits, or managing the peoplewho do, this book is for you. Programming EmbeddedSystems will help you develop the knowledge and skills youneed to achieve proficiency with embedded software.Praise for the first edition:"This lively and readable book is the perfect introduction for those venturing into embedded systems software development for the first time. It provides in one place all the important topics necessary to orient programmers to the embedded development process.--Lindsey Vereen, Editor-in-Chief, Embedded Systems Programming Spis treści: Programming Embedded Systems SPECIAL OFFER: Upgrade this ebook with OReilly A Note Regarding Supplemental Files Foreword Preface Why We Wrote This Book Intended Audience Organization Conventions, Typographical and Otherwise Obtaining the Examples Online Using Code Examples Comments and Questions Safari Enabled Personal Comments and Acknowledgments From Michael Barr From Anthony Massa 1.
