一个采用AT89C51和AD0809组成的液晶数字电压表 有proteus仿真电路-AT89C51 and the AD0809 with the composition of a liquid crystal digital voltmeter are proteus simulation circuit

AT89c51,用protues来仿真AD0804的仿真，并且keil程序，应该不是很难~-AT89c51, with protues simulation to simulate the AD0804, and keil procedures, should not be difficult ~
