摘要
该系统给出了一种在嵌入式硬件平台及Linux操作系统上,首次实现MP3播放与LED同步显示歌词的设计方案;在介绍了本系统的总体构架的基础上,结合嵌入式Linux的驱动程序设计框架,给出了MP3歌词在LED显示屏上显示的驱动程序设计,以及歌词同步的应用程序。本实验完成了在低端LED显示屏上实现多媒体化功能的设计,适用于曲艺团体或公众性场合集体教学或练唱的需求。
A design scheme of a lyric display on a LED screen is firstly realized on the embedded hardware platform in the Linux system. After the introduction of the whole system framework structure, this paper analyzes the programming of the MP3 lyric displayed on a LED screen and the lyrics synchronized applica- tion, by combining with the embedded Linux driver program framework. The system has completed multimedia function on a low-end LED display screen, and applies to the requirements for opera group and public teaching or rehearsal.
