，我们开始迈入单片机的世界。在我们开始这一章具体的学习之前，有必要给大家先说明一下。在以后的系列文章中，我们将以51内核的单片机为载体，C语言为编程语言，开发环境为KEIL uv3。至于为什么选用C语言开发，好处不言而喻，开发速度快，效率高，代码可复用率高，结构清晰，尤其是在大型的程序中，而且随着编译器的不断升级，其编译后的代码大小与汇编语言的差距越来越小。而关于C语言和汇编之争，就像那个啥，每隔一段时间总会有人挑起这个话题，如果你感兴趣，可以到网上搜索相关的帖子自行阅读。不是说汇编不重要，在很多对时序要求非常高的场合，需要利用汇编语言和C语言混合编程才能够满足系统的需求。在我们学习掌握C语言的同时，也还需要利用闲余的时间去学习了解汇编语言。 -We began to enter the world of single. Before we begin this chapter specific before learning , it is necessary to give everybody to explain to you. Later in the series of articles, we will be the 51 kernel SCM as a carrier, C language is the programming language, the development environment for the KEIL uv3. Why use C language development, benefits it is self-evident, development speed, high efficiency, high rate of code reuse, structural clarity, especially in large programs, and as the compiler is ceaseless upgrade, the compiled code size and assembly language gap is more and more small. On the C language and assembly for what, like that, every once in a while there will always be people who provoke this topic, if you are interested, can go to online search related posts to read. Not to say that the assembly is not important, in many of the timing requirements of very high situation, need to use assembly language and C language programming to meet the requirements of the system.
