基于CDP1854的智能数据适配器设计与使用

摘要

An asynchronous receiving/synchronous transmitting data adapter is an interface circuit realizing message interchange between the PC machine and the controlled terminal.For realizing message transmission,the serial asynchronous message from the serial port of PC is needed to transfer to synchronous message,which is transmitting to the controlled terminal then.This adapter can realize asynchronous receiving/serial transmitting,so as to realize the PC machine to control the terminal.%异步接收/同步发送数据适配器是PC机与受控终端之间实现信息交换的接口电路。为了实现信息传送,需要将从PC机串口发送来的串行异步信息转换为同步信息发送出去,该适配器可实现异步接收/串行发送,达到PC机控制受控终端的目的。
