摘要
在单片机串行通信中,要求发送和接收的波特率保持一致。首先以MCS-51为例,分析了波特率的误差源和允许的波特率误差,然后介绍了一种自动调整波特率的方法。在这种方法中,数据的格式、波特率的选择都是通过软件来实现的,应用十分方便。
In microcontroller serial port communication,the system require that the baud rate of dispatcher and sink should keep consistent. Firstly, the error source of baud rate and the allowable baud rate error are analyzed with the example of MCS-51. Then a method of baud rate autoregulation is presented. In this method, the data style and baud rate are selected by software, and the application is quite easy.
