本系统以Atmel的AT89c52单片机为主控制器，通过制作硬件电路和软件的设计编写，然后进行软硬件的调试运行，最终达到设计电路乐曲弹奏播放功能和存储重放音乐功能。设计中运用中断系统和定时/计数原理控制电子音乐器发生，并对所需的音阶和贝斯用相应的程序语言编写来实现，用8段数码显示管显示所弹奏的乐谱内容。将两个89c52单片机的串行口连接起来，实现5米以外的通信。输出通道通过一个功率放大器驱动扬声器发声。-This system to Atmel' s AT89C52 single-chip microcomputer-based controller, through the production of hardware circuitry and software to prepare the design and then proceed to debug hardware and software to run, eventually to meet the design circuit playing music playback and storage of music playback function. The design of systems and the use of interrupt timing/counting principle to control electronic music device happened, and the necessary scale and bass with the preparation of the corresponding programming language to achieve with digital display 8 display the content by playing the music. Two 89c52 single-chip serial port of linking implementation of communication other than 5 meters. Power amplifier output channels through a voice-driven speaker.
