摘要
提出一种基于BU9435的MP3播放模块的软硬件设计方法。由于BU9435自身带有USB和SD主机控制器和MP3解码器,不仅极大简化了外围电路,而且支持U盘和SD卡作为存储介质。该模块以I2C总线为控制接口,只要系统能提供I2C接口,就可以方便地将该模块嵌入到系统中。
The design method of software and hardware in embedded MP3 player based on BU9435 is proposed.Because of BU9435 integrating the USB and SD card HOST control function,this MP3 player module can support U disk and SD card as storage media and has very simple peripheral circuit. The control interface of this module is I^2C bus. As long as system has I^2C controller, this module can be easily embedded into system.
