Description: 首先要把51hei单片机开发板上的ne555的方波输出信号J7的第一脚用杜邦线,引入P3.2口,数码管即可显示ne555震荡电路当前的频率值,旋动PR1电位器可发现数字有变化.
原理：1秒钟内计数外部脉冲个数，如计数1000次，则表示频率为1000Hz
-First, we should 51hei microcontroller development board ne555 square wave output signal with the first pin of J7 DuPont lines, the introduction of P3.2 mouth, can show ne555 digital frequency oscillator circuit current value, rotating the potentiometer can be found in PR1 numbers have changed. Principle: 1 Number of seconds to count external pulses, such as the 1000 count, then the frequency of 1000Hz
