摘要
本文介绍了一种USB接口电路的设计,该设计硬件上是基于USB总线转接芯片CH341T来实现,软件上利用VB的MSComm控件快速开发这一简单的USB转光纤设备,实现了USB主机端和设备端的成功通信,并在实际应用中达到了工具携带方便,数据传输准确、快速的效果。
A universal interface circuit of USB bus is presented, which hardware is realized based on a special USB transfer chip,CH341T. And a convenient method to quickly develop USB-Fiber devices Using MSComm control in VB program is discussed, Achieved a USB host-side and device side successing communication. In the practical application, the tool is easy to carry,and the data transmission is accurate and rapidly.
