基于DSP的触摸式MP3的设计

The design of MP3 player with touchable style based on DSP

介绍了利用数字信号处理芯片TMS320LF2407A实现触摸式MP3播放器设计的方案。采用芯片VS1003B进行MP3的解码,减轻了系统的负担。采用ILI9320为驱动器的真彩彩屏,并采用TM7843为控制器的4线电阻式触摸屏作为人机交互平台,实现了MP3等文件的播放、歌词的同步显示以及彩图显示等功能,相关文件存储在SD卡中。

This article introduced a method to achieve the MP3 player with touch style based on DSP chip named TMS320LF2407A. It lightened the system that VS1003B was used to decode MP3. As interface, the colorful screen drove by IL- 19320 and the touchable screen drove by TM7843 were adopted. The system realized that MP3 files could be played with the lyric displayed synchronously and colorful picture could be displayed and so on. All the files were stored in SD card.
