【摘要】 阐述了 MCS5 1和 MCS96系列单片机与 PC微型计算机间串行通信模式及其波特率计算式 ,推导了两机通信时波特率误差的允许范围值 ,利用反推法 ,在满足通信波特率误差的允许值前提下 ,计算了 MCS5 1/ 96系列单片机与 PC微机最高串行通信速率的波特率因子 ,并给出了具体实现的 C程序代码更多还原

【Abstract】 The mode of serial communication and the calculating expressions of their baud rate between MCS51/96 single chip computer and microcomputer are expatiated in this paper The permitted error of baud rate is deduced On the condition of the permitted error of communication baud rate, the highest baud rate coefficient of serial communication between MCS51/96 single chip computer and microcomputer are calculated, and the program written by C language is given更多还原
