摘要
本论文是利用单片机及WAVE6000编程软件编程和PROTEUS单片机仿真软件和电子电工等方面知识,用WAVE6000编程软件编程，用PROTEUS单片机仿真软件仿真。最后制作实物，将程序下载到真正单片机中，利用I/O口产生一定频率的方波，驱动蜂鸣器，发出不同的音调，从而演奏乐曲（最少三首乐曲，每首不少于30秒）。以WAVE6000编程软件和PROTEUS软件来进行仿真、分析，调试,为设计提供了一个方便、快捷的途径，为我们节约了设计时间。

Abstract
This paper is the use of SCM and WAVE6000 programming software programming and PROTEUS SCM simulation software, such as electrical and electronic knowledge, with WAVE6000 programming software programming, with PROTEUS SCM simulation software simulation. Finally production in kind, will be downloaded to a genuine process of SCM, the use of I / O for a certain frequency of the square, drive buzzer, a different tone, so as to play music (at least three pieces, each of not less than the first 30 seconds). WAVE6000 to software programming and simulation software to PROTEUS, analysis, debugging, as the design provides a convenient, fast way for us to save the design time.

Key word: AT89S52 SCM; frequency; square; pitch
