摘要
针对实现嵌入式USB主机互联的需求,提出了以PDIUSBD 12为USB控制芯片的USB On-The-Go(USB OTG)设备解决方案。通过分析芯片驱动、控制单元数据交换程序设计,建立PC-PC USB接口连接器,为USB主机间提供对等功能的USB设备接口,通过统一的数据缓冲区,实现了两台USB主机不借助于USB集线器的互联方案。
This paper aims at realizing the demanding of flushbonding USB HOST interconnects;takes PDIUSBD 12 as USB control chip, through chip drive and control unit data exchange programming, establishes PC- PC USB interface connector, provides USB host with peer to peer function USB equipment interfaces , and sets up unified data buffer, which makes intexconnection of the USB hosts without USB hub.
