浅议降低51单片机定时器定时误差的几种方法

摘要

51单片机在当前控制检测系统中的应用越来越多，对其定时的精确要求也越来越高。虽然51单片机自带的16位定时/计数器较为精确，但是在实际应用过程中难免存在误差，而且这个误差不可避免，所以降低51单片机定时器误差就显得尤为重要。%　　51 single-chip computer has a wide range of application in the current control and detection system. The requirement for timing accuracy is higher. Although the 16-bit timer/counter is relatively accurate, the error in the actual application is inevitable. So it is important to reduce the error of timer of 51 single-chip computer.
