说明：  C 语言嵌入式系统编程修炼之一:背景篇 不同于一般形式的软件编程，嵌入式系统编程建立在特定的硬件平台上，势必要求 其编程语言具备较强的硬件直接操作能力。无疑，汇编语言具备这样的特质。但是，归 因于汇编语言开发过程的复杂性，它并不是嵌入式系统开发的一般选择。而与之相比， C 语言--一种"高级的低级"语言，则成为嵌入式系统开发的最佳选择。笔者在嵌入式系 统项目的开发过程中，一次又一次感受到C 语言的精妙，沉
(C language programming of embedded systems, one practice: background papers Unlike most forms of software programming, embedded system programming based on a specific hardware platform, it is bound to require Its programming language with a strong capacity to operate the hardware directly. There is no doubt that this kind of assembly language with the characteristics. However, in the final In assembly language because of the complexity of the development process, it is not the development of embedded systems in general to choose. Compared with C language- a kind of "junior high" language, the development of embedded systems has become the best choice. The author in the embedded line EC project development process, time and again to feel the exquisite language C, immersed in C language for embedded development with For convenience. )
