单片机采集到的车窗电压AD采样值，用MATLAB进行数据分析，电压变化曲线图像显示，以便进行模拟算法验证。-The car windows Voltage AD value from SCM AD-sampling collected, using MATLAB data analysis, image display voltage curves for simulation algorithm validation.

依靠ADC0808对输入电压进行A/D转换，之后输进单片机中，再显示在显示屏上-Rely on ADC0808 to A/D conversion, the input voltage after losing in the single chip microcomputer, is displayed on the LCD screen
