单片机音乐播放器功能多样性的设计与实现

Design and Simulation of Mmulti- functional Music Player Using Micro- controller Unit

本文论证了基于通用8位单片机的音乐播放器多功能化的硬件实现与软件设计。笔者选用了AVR系列中最具代表性的高性能8位单片机AT90S8515，辅以少量各类外围电路，使其成为能够完成数据存储，音频解码、播放，LCD用户信息显示，用户预置曲目演奏，即时演奏等多方面功能的便携式音乐播放器。

This paper demonstrates the realization of hardware and design of software of multi -functional music player which is basic on general - purpose 8 - bit micro - controller. The author uses the high - performance 8 - bit micro -controller AT90S8515 which is the most representative in AVR series, and it is supplemented by various types of peripheral circuits, in order to make it a portable multi - functional music player which supports data storage, audio decoding and playing, LCD user information displaying, tracks presetting, instant playing, etc.
