Sauare_wave_changed-V1.2
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.)

2052Player
说明： 由于不满意语音芯片的复制性差，于是自己做了一个语言模块，用STC12LE2052单片机的PWM功能播放声音，从Wave文件中提取的声音数据通过串口从计算机下载，存储在串行Flash芯片SST25VF016B中，可进行单段播放和循环播放，单个模块的制作成本应该在30元以下，可以播8K8位的声音256秒。(Not satisfied with the voice chip, as a result of poor copy, so do a language module, with the STC' s 2052 single-chip PWM function to play a sound, from the Wave files to extract the audio data downloaded from the computer through the serial port, is stored in the Serial Flash chip, can play single player and recycling, the production costs of a single module should be below 30, you can broadcast the voice of 8K8-bit 256 seconds.)
