Description: 数字电压表
AD芯片：
采用8位串行A/D转换器ADC0832。
● 8位分辨率，逐次逼近型，基准电压为 5V
● 5V单电源供电
● 输入模拟信号电压范围为 0～5V
● 有两个可供选择的模拟输入通道
显示：
使用三个数码管。
显示范围：
0.00 － 5.10 （单位：V）
连接方式：
AD_CLK → P1.0
AD_DAT → P1.1
AD_CS → P3.4
模拟输入 → CH0
(AD_DAT = DO + DI)
ADC0832输出最大转换值＝FFH (255)
设定最大测量值＝5.1V
255X=5.1 X=0.02 即先乘2再除以100
（小数点放在第三位数码管）- Digital voltmeter
AD chip: Uses 8 serial A/D switch ADC0832. * 8 resolution,
gradually approaching, the datum voltage is 5V * the 5V single power
source power supply * input simulated signal voltage scope is 0 ~ 5V *
has two to be possible to supply the choice the analog input channel
Demonstrated: Uses three digital tubes.
Demonstrates the scope: 0.00 - 5.10 (unit: V)
Connection way:
AD_CLK -> P1.0 AD_DAT -> P1.1 AD_CS -> P3.4 analog input -> CH0
(AD_DAT = DO DI)
ADC0832 output biggest transformation value = FFH (255)
establishes greatest observed value = 5.1V 255X=5.1 X=0.02 namely
first to ride 2 to eliminate again by 100 (decimal point puts on third
