摘要:以学习单片机为目的,为在没有仿真器和目标板的情况下对单片机内部程序运行时有
感性的认识,以常用的 89C2051 单片机为核心,利用 Proteus 仿真软件的硬件仿真模块建立
一个正弦波发生电路,并运用 C 语言编写相应程序,结合所设计电路在 Proteus 仿真软件的
软件仿真功能进行了综合仿真,并把仿真结果和实际电路与程序运行的结果进行了比较。据
此,通过从实践出发来,把实践与理论结合在一起的学习方法来达到入门单片机知识。

Abstract: Aiming at single puter study, and helping to build a perceptible feeling and
visible sensation without the emulator and target PCBA when study the single puter
technique, and helping to understand the principle when the program running in the
puter, with the software tools Proteus, an emulate circuit and its C language program
used for generating a sine signal had been designed based on the single puter 89C2051.
And the e signal wave had pared with the wave from real circuit after this design
had been emulated with Proteus. With this practice, the basic knowledge about the puter
may be understoodwell.
Key words: Single puter,puter Emulate, Proteus, Sine signal

对于单片机的学习,由于其比较抽象,特别是在编写程序时,完全只是凭借程序员周
密的逻辑思维来进行程序设计,为了让程序设计员更好的理解和调试其所设计的程序,所有
单片机生产厂家都针对他们的单片机系列设计生产了相应的仿真器。然而这些仿真器的价格
却不菲,无凝这是初次学习单片机时重要考虑的因素。而
