| 摘 要： | 实现了以ＩＢＭ－ＰＣ为主机，用ＲＳ４２２方式连接多台ＭＣＳ－５１单片机的通信系统。该系统完全以中断方式收发数据，比传统的单片机查询方式每字节大约节省时间６ｍｓ（约３０００条指令）；同时解决了通信数据误码、通信死锁等问题。该系统通信软件结构清晰，便于增加功能。

| Abstract: | TMe communication system , connected IBM-PC computer with the MCS-51 monolithic microcomputers by RS-422 serial bus ,is realized.The monolithic microcomputers received and send datas in the interruption mode. It is saved the time about 6 ms than traditional polling mode when sending and receivingper byte. The problem of locking and code error in communication is resolved. The structure of the saftware is distinct and simple,the function can added simplely. |
