双步进电机综合控制 用于51单片机 (Dual stepper motor integrated control)

酒精测试仪proteus仿真，单片机进行分析处理，判断是否醉酒驾车，再通过液晶板显示出来。(Alcohol Tester proteus simulation, analysis and processing microcontroller to determine whether drunk driving, and then through the LCD panel display.)

正弦信号发生程序。使用声卡产生正弦信号输出，可以用来调音！(Sinusoidal signal procedures. Sinusoidal signal generated using the sound card output, can be used to tuning!)

宽频放大器,有以下功能: 预置增益,增益加/减,显示输出电压有效值,自动增益 显示有效值. 增益输入及加减 自动增益没有实现(Wideband amplifier has the following functions: Preset gain, gain plus/minus, the display output voltage RMS, automatic gain display rms. AGC gain input and subtraction is not implemented)

说明：  OCM12864参考程序_ 挺好的 适合做参考程序(_ OCM12864 reference to procedures for the very good reference procedures)

时钟显示,在实验二的作业里面，希望对大家有用，能够帮助到大家(show the time.)
