c51单片机AD的的应用，非常的详细-c51 AD of the application microcontroller, extremely detailed ~~~~~~~~~~~

可以对单片机采集的AD数据进行实时显示，并保存在.dat文件中，用excel对数据进行后续处理，十分方便使用-Real-time display microcontroller AD data collected and stored in the dat file excel subsequent data processing, and very easy to use

基于12单片机通过光敏电阻用AD将信息反馈给lcd屏幕(The information is fed back to the LCD screen via a photosensitive resistor)
