摘要
利用MCS-51系列单片机的定时/计数器可以非常方便地进行信号的频率测量,文中给出了3种基于单片机的测频方法及程序,且系统硬件电路结构简单,软件设计容易。
The timer counter of the MCS-51 singlechip computer can be easily used in the frequency measurement of signals.This paper presents three practical methods of measuring frequency based on the MCS-51 singlechip computer in which the hardware is simple and the software is easy.
