基于Proteus和Keil的单片机演奏乐曲的仿真

Simulation of MCU's music playing based on Proteus and Keil

针对乐曲演奏在单片机实践教学中实现的不足,介绍了基于Proteus和Keil联调的单片机演奏乐曲的设计方法,通过对乐谱的音符和节拍进行编码,实现了乐曲演奏的功能。仿真结果表明:该方法电路简单、调试方便,只需简单的修改程序就可实现其它歌曲的演奏。

According to shortage of the music playing in MCU practical teaching, the design method of MCU＇s music playing based on the joint of Proteus and Keil is introduced, and it can achieve music playing function by the coding of notes and beats of music. The result of simulation shows that the method of design is simple, easily debugging and has achieved other song＇s playing for simple modification program.
