基于嵌入式系统的MP3播放器设计

The Design of the MP3 player based on embedded system

以MSP430F149作为核心控制器和VS1003音频解码器为基础,设计了一种带SD卡的MP3播放器,给出了MP3播放系统的软硬件设计。在硬件设计上解码器与存储器分离,增加了存储容量,极大地方便了应用,同样节省了成本。在软件设计上使用条项菜单方式进行管理,这样可以方便地为它进行硬件或软件方面的升级。经过测试,该系统播放MP3效果较好。

This design is based on MSP430F149 as the core controller and VS1003 as audio decoder; it designs a simple MP3 player based on the SD card and gives the hardware and software. In the design of hardware, the decoder and memory are sep- arated which is increase the storage capacity, In the design of software, it uses menu items to manage so that it can easily go on the upgrades of hardware or software which in order to increase the other functions of this MP3 player. After testing, this MP3 player can play a high - quality audio files and the effect is also good.
