摘要
文章论述了基于内存映射模式的RS-485智能通信板的设计与实现过程。此通信板是一块采用了内存映射技术的PC机插卡,它与PC机之间通过公共数据区交换数据,采用中断方式进行相互联络,快速高效,完全可以满足小型集散控制系统中通讯控制机的要求。
In this paper,a method for designing and implementing the RS- 485 intelligent communication card cased on memory mapping is discussed,this communication card is a PC card using memory mapping technique,it exchange the data with PC through the public data block,and communicate through interrupt mode. The speed of data exchange is higher the traditional technique,and can satisfy the need for the minitype DCS.
