摘要
实现了一种基于USB海量存储器的车载DVD系统。系统使用SPHE8202TDVD处理器为核心构建系统硬件平台,通过编写枚举程序实现自动识别并配置USB海量存储器;系统按照BULK-ONLY传输协议在USB海量存储器与USB主机间进行数据交换,实现了在车载DVD系统中使用USB海量存储器播放音视频多媒体文件的功能。
The car DVD system based on USB mass storage device is implemented.The system sets up a hardware platform used the SPHE8202T DVD CPU.By programming enumerate software,the system can identify and configure USB mass storage device automatically.According to the Bulk-only protocol,the system exchanged data between USB mass storage device and USB Host,realizes the function that played the audio or video multimedia files used USB mass storage device in the car DVD system.
