基于EPM7192的RS232转IO接口模块的设计与实现

摘要

This paper introduces the design method of control card including software and hardware.The core of card is EPM7192.It consists of 5 parts:power circuit,crystal circuit,232 interface circuit,IO interface circuit as well as main process circuit.The control communication interface uses RS232,The paper emphasized on the design method of mixture input which include sch and VHDL,It also emphasized on depiction the application of ISP software [2].It also realizes the software receiving control component used by VHDL,and gave out the test application in the end.%介绍了用于自动控制设备控制板卡的软硬件设计方法,该卡以EPM7192为核心,由电源电路、晶振电路、232接口电路、IO接口电路、主处理电路等5部分组成,控制通讯接口采用RS232,叙述了用混合输入实现该设计的方法[1],并用VHDL语言实现整个软件接收控制部分,最后给出了应用测试情况.
