| 摘 要： | 目前,PC/104与PC机之间的通讯一般是以串行通讯或者并行通讯两种方式来实现的,然而USB通讯正以其高速性和连接灵活性等优点而被广泛关注。为实现PC/104与PC机之间的USB通讯,本文基于USB总线接口芯片CH375设计了PC104-USB转接板,详细描述了通讯中涉及的以伪中断方式发起上传数据流,以下传API发起下传数据流的通讯方式,并给出了相关程序代码。

| Abstract: | At present, communication between PC104 and PC is commonly realized by way of serial communication or parallel commu- nication, however USB communication enjoy great popularization with many advantages such as high speed, joint flexibility and etc . In order to realize the USB communication between PC104 and PC, PC104 transfer card is designed based on CH375 chip, then the way of that launching uploading data stream with pseudo interrupt mode and launching downloading data flow using API is mainly described. Finally the relative procedure code in the method is provided in the article. |
