摘　　要：目前,MIDI音乐正因其存储尺寸小,编辑容易等特点而越来越受到人们的青睐.本文主要介绍MIDI音乐的制作和播放。系统以AT89C51单片机为控制核心,充分利用其中断和定时系统,通过和H6188音源芯片的串口通信,实现了MIDI消息发送.H6188内置合成器经过对MIDI消息的解码,产生声音波形,发出MIDI音乐。实验表明,系统成本底,可靠性高,音色优美,有广阔的应用前景.At present,MIDI music is becoming more and more popular,because it has a small size and can be edited easily.This paper mainly introduces the production and player of MIDI music. AT89C51 is the control core of the system. The timer and intermit system is fully made use of in system.Through communication with the H6188,AT89C51 sends out the MIDI messages.The mixer in H6188 decodes the MIDI messages, produces the sound wave,finally gives out the MIDI music. Experiments show that, the system costs low and sounds beautiful.It has a broad application prospects.
