摘　　要：介绍了基于Proteus的单片机演奏系统的基本原理、硬件电路及软件设计.在编辑乐曲的过程中,每一音符对应着确定的频率,将每一音符的时间常数和其相应的节拍常数作为一组,按顺序将乐曲中的所有常数排列成一个表,然后由查表程序依次取出,产生音符并控制节奏,就可以实现演奏效果.实验结果表明,该方案电路简单,切实可行且效果不错.The basic principle, hardware circuit and software of performance system by single-chip computer are introduced. When editing pieces of music, each note has a corresponding frequency, taking time constant of each note and relevant rhythm constant as a group and arranging all constants of music as a table, then taking out in turn according to checking program, producing note and controlling rhythm to achieve musical performance. It shows that the circuit is simple and the scheme is feasible and effective.
