说明：  每一个嵌入式系统都是独特的，其硬件部分对它的应用目标来说是高度专用 的。这就导致了嵌入式系统编程的涉及面很广，而且可能会需要很多年才能掌 握它。不过，几乎所有的嵌入式软件开发都使用了C 语言。这本书就是要教你 怎样在嵌入式系统中使用C 和C 的派生语言，C++。
(every one embedded system is unique and its hardware part of it is the objective of the highly-specialized. This led to the Embedded Systems Programming is a very broad and may take many years before they can acquire it. However, almost all of the embedded software development using C language. This book is to teach you how the Embedded System C and C use a derivative language, C.)
