| 摘 要： | 介绍了以MCS-51单片机为核心器件的可变调音乐演奏系统。具体介绍了音乐演奏系统的基本原理、硬件电路及软件设计。为了单片机控制的音乐程序能实现变调变速,通过模仿钢琴键盘演奏,把各个音节的频率写到表里,通过查表来实现变调和变速。采用MCS-51单片机及汇编语言组成一个单曲演奏系统。

| Abstract: | A musical performance system that can modify tone is introduced,its core device is the MCS-51 single chip processor.It's basic principle,hardware and software design specifically are introduced.In order to change tonality and velocity of the music program that controlled by SCM,imitating playing piano keyboard,the frequency of each syllable is write on a list,through looking up the list to realize changing the tonality and velocity.The single performance system is composed by using MCS-51 SCM and assembly language. |
