Description: 本例利用ADC0809 的A/D 转换原理，将被测的多路模拟量转换成数字量,并
用数字方式显示测量结果。本系统以单片机AT89C52 为系统的控制核心,结合A/D 转换
芯片ADC0809 设计一个多路电压采集系统，其中A/D 转换结果经过AT89C52 处理，最后
通过数码管显示相应的数值。本系统通过一个按键可以选择8 路0－5V 之间的直流电压
值进行测量，并在四位数码管上显示相应的数值。读数据准确，测量方便。-In this case the use of ADC0809 A/D conversion principle, the measured multi-channel analog to digital conversion, and measurement with digital display. The system of control for the system AT89C52 microcontroller core, combined with A/D converter chip ADC0809 Multi-voltage design a collection system, in which A/D conversion result after AT89C52, at last, through the digital display the corresponding value. The system via a button you can choose between 8-way 0-5V DC voltage measurement and digital display of the four corresponding values. Reading the data is accurate, convenient measurements.

Description: 8路输入模拟信号数值显示巡检数字电压表可以测量0--5V的8路输入 模拟信号电压值，并在4位LED数码管上轮流显示或单路选择显示。
按系统功能实现要求，决定控制系统采用AT89C52单片机，A/D转换采用ADC0809。系统除能确保实现要求的功能外，还可以方便地进行8路其他A/D转换量的测量、远程测量结果传送等扩展功能。
采集 8 个通道的模拟量在数码管显示出来。模拟量值的测量范围是0-255,第2个数码管用于显示哪一个通道，后2个数码管用于显示采集的模拟量的值，每秒钟显示切换一下通道。
本设计还有通道选择的功能．有两个按键,一个是调节轮流显示和选择通道两种功能的转换，另一个是选择通道的切换。要注意的地方：
1、只有当轮流显示的通道快显示到通道8后，长按住功能转换键等出现数码管全熄灭后再放开，就会转到选择通道的功能。
2、切换通道时，也要长按一会，等出现数码管全熄灭后再放开。-8 road input analog signals that digital voltmeter measurement circuit can 0-5 V 8 road input analog signals voltage value, and in the four LED digital display or taking turns on the single option to show.
According to the system functions requirements, decided to control system adopts AT89C52 single chip microcomputer, A/D conversion using ADC0809. The system can ensure the request except functions, but also can be convenient to 8 way other A/D conversion amount of measurement, remote measurement results delivery etc function expansion.
8 channel simulation collection of digital tube in the display. Simulation of the value of measurement range is 0-255, second digital tube is used to show which channel, 2 digital tube used to show the simulation of the value of the collection of every second. The channel that switch.
This design and channel selection function. There are two key, is a regulation that choose channels and in turn two function conversion, the other is a choice
