单片机双串口功能在实时数据处理中的应用

DUAL SERIAL PORT FUNCTION OF SINGLE CHIP MICROPROCESSOR & APPLICATION IN REAL TIME DATA PROCESSING

通过实例,重点介绍了77E58单片机双串行口的工作原理,编程方法,及其它新增加的一些辅助功能的使用:方法。针对双串口应用给出了利用环形队列的中断程序设计思路,提高了系统的实时性能。

This paper introduces the working knowledge and programming method of 77E58 dual port single chip microprocessor by examples. Other new functions are also given. Aimed at dual serial port application, the program design theme is proposed using circular queue which increases the real - time performance of the system.
