随着信息技术革命的不断深入,以及计算机技术的快速发展,单片机的应用越来越广泛了,并且已经逐渐地发展成为了一门比较关键的技术学科。本文所介绍的是一种比较简易的单片机音乐盒的设计以及其相关的实现方案,利用的是AT89C51单片机。通过乐谱的音节以及节拍混排的方式进行了一次编码,从而实现了乐曲的播放这一功能。 With the continuous deepening of the information technology revolution and the rapid development of computer technology, the application of the microcontroller has become more and more widespread, and it has gradually become a key technology discipline. Introduced in this article is a relatively simple single-chip music box design and related programs, using the AT89C51 microcontroller. Through the syllables of the score and the tempo mixing, a function of encoding music is realized.
