利用实验板上的ADC0809做A/D转换器，实验板上的电位器提供模拟量输入，编制程序，将模拟量转换成二进制数字量，在数码管的最高两位显示出数字量来。另外要把模拟量值在数码管的最低三位显示出来。例如显示“80 2.50”（ 其中80是采样数值，而2.50是电压值。要求程序可连续运行以便测量不同的模拟电压（类似于电压表）
（注意：多次采集求平均值可提高转换精度）
-Experimental board do ADC0809 A/D converter, test board provides analog input potentiometer, the preparation process, the analog content into binary numbers, the highest in the digital control two figures show the volume. We should also simulate the minimum value in the digital control of three is displayed. For example, show " 80 2.50" (80 is the sample value, but 2.50 is the voltage. Requested program can be run continuously in order to measure different analog voltage (similar to the voltage table) (Note: multiple collection can improve the conversion accuracy of the mean value)
