基于C51语言的星载嵌入式软件定时器管理方法

The Management Method of Onboard Embedded Software Timer Based on C51 Language

本文通过对星载51系列单片机定时器常见问题进行分析,归纳出三类典型问题,分别给出解决方案,并在此基础上总结出一套基于C51语言的星载嵌入式软件定时器管理方法,该方法可以解决因中断冲突和定时器进位而产生的问题,同时可推广到其他嵌入式领域的定时器使用中。

Based on the analysis of the problem of 51 series single-chip timer on board, this paper summa-rizes the three types of typical problems, and gives a solution. On this basis, we summed up a management method of onboard embedded software timer based on C51 Language. The Method can solve the problem caused by interrupt conflict and timer carry, and can be extended to other embedded field of use of timer.
