在众多单片机中51 架构的芯片风行

很久，学习资料也相对很多，是初学的较好的选择之一。51 的编程语言常用的有二种，一

种是汇编语言，一种是C 语言。汇编语言的机器代码生成效率很高但可读性却并不强，复

杂一点的程序就更是难读懂，而C 语言在大多数情况下其机器代码生成效率和汇编语言相

于汇编语言很多。-In many microcontroller architecture chips 51 popular

Long learning materials is relatively a lot, is one of the better choices novice. 51 programming languages commonly used two kinds, a

Species are assembly language, one is C language. Machine assembly language code generation efficiency is high, but they are not readable strong, complex

Miscellaneous point program is even more difficult to read, but in most cases the C language code generation efficiency of their machines and assembly language

When, however readability and portability is far more than assembly language, and C can also be embedded assembler language to address the high aging

Write problematic code. For the development cycle, the medium and large software written in C language development cycle is usually smaller
