摘要
MCS-51串行通信程序一般是利用发送中断标志位TI和接收中断标志位RI来进行设计,采用查询或中断两种编程方式。本文剖析查询方式连续串行发送数据时源于硬件时序的数据通信错误。
Usally,we use the transmitting breaking sign bit TI and the receiving breaking sign bit RI to design MCS-51 serial communication programm, there are tow method --Checking -Asking and Breaking can be used ?This article analyses the cause of the serial communication error stem from the Hardware Time Order when Checking-Asking method is used to transmit data.
