8、可变频率方波发生器 用单片机的定时器设计一个频率可变的方波发生器，输出频率范围1Hz~500Hz，频率输出精度为0.5Hz。要求可以实时显示当前输出的频率，可以用键盘来设定方波发生器的输出频率，具有直接设定或逐渐调节的功能，调节分辨率和显示分辨率均为0.5 Hz，其它电路自由发挥。(8, variable frequency square wave generator with single-chip microcomputer timer design a variable frequency square wave generator, the output 1 Hz ~ 500 Hz frequency range, frequency output precision is 0.5 Hz. Requirements can real-time display current output frequency, can use the keyboard to set the output frequency of square wave generator, has the function of directly set or adjust gradually adjust the resolution and display resolution of 0.5 Hz, free play other circuits.)
