摘要
介绍了在S3C44B0X上通过SL811H/S扩展主从式USB接口的硬件和软件设计方法,并且通过修改描述符的方法快速方便地开发了USB设备PC机上的驱动程序。最终实现了嵌入式系统USB主从模式的快速切换以及在主机模式下与U盘、从机模式下与PC机的通信。
The hardware and software design for ARM appending USB interface is presented, in which SL811 is used for both host mode and slave mode in USB. The method which develops the USB drive in PC by modifying descriptor is also discussed. The interface can be used in embedded system which need fast switch between USB host mode and slave mode. And it can be communicated with U disk in host mode and PC in slave mode.
