功能描述： 利用AT89S51单片机的T0、T1的定时计数器功能，来完成对输入的信号进行 频率计数，计数的频率结果通过8位动态数码管显示出来。要求能够对2－40KHZ 的信号频率进行准确计数，计数误差不超过2/1-Functional Description: Using AT89S51 MCU T0, T1 timing counter function, to complete the input signal frequency counting, counting the frequency of 8 resulted in the adoption of dynamic digital tube display. Request to the 2-40KHZ signal frequency accurately count, counting error of less than 2/1

通过C语言控制数码管动态扫描显示，通过按钮可以控制数码管的大小，然后进行定时器中断进行倒计时。-Through the C language to control the digital control of dynamic scan showed that the adoption of digital control button can control the size, and then proceed to the countdown timer interrupt.

运行于c51单片机上的用keil c创建的C源程序,采用PDIUSBD12接口。-run on the microcontroller with Keil c create C source code using PDIUSBD12 interface.

简易频率计，一个中断，一个定时器，适合初学者学习中断、定时器，动态扫描显示。-Simple frequency meter, an interrupt, a timer, suitable for beginners to learn interrupt, timer, dynamic scan shows.
