摘要
以MSP430F149作为核心控制器,结合VS1003音频解码器,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;在软件设计上,使用条项菜单方式进行管理,可以方便地进行硬件或软件的升级。经过测试,该MP3播放器播放效果较好。
Taking MSP430F149 as the core controller and VS1003 as audio decoder, an MP3 player with SD card is designed. System hardware and software designs are given. In the design of hardware, the decoder and the memory are separated, increasing the storage eapaeity; in the design of software, management is achieved through the menu items, facilitating the hardware and software upgrading. Test shows that this MP3 player can play high-quality audio files with good effect.
