说明：  本书分为两部分。第 1 ~ 10章广泛介绍嵌入式系统，使用mbed展示如何应用它快速地 进行成功的嵌入式系统设计。这几章旨在全力帮助读者掌握一系列精心构建的概念和练习 ，从基本的原理和简单的项目入手，逐步完成更高级的系统设计。第 11? 15章在此基础上进 入到了许多更高级的系统设计领域。这里讲的速度可能会有点快，你会发现需要进行更多的 背景研究。
(The book is divided into two parts. In Chapter 1 to Chapter 10, embedded system is introduced widely, and mbed is used to show how to use it to design successful embedded system quickly. The purpose of these chapters is to help readers master a series of carefully constructed concepts and exercises, and gradually complete a more advanced system design from the basic principles and simple projects. On this basis, chapters 11-15 enter into many more advanced system design fields. It may be a little fast here, and you will find that more background research is needed.)
