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 Voltage Meter AD-Chip: 8-bit serial A/D converter ADC0832. ● 8-bit resolution, successive approximation type, the base voltage of 5V ● 5V single power supply ● analog signal input voltage range of 0 ~ 5V ● have two options display analog input channels: the use of three digital tube. Display range: 0.00- 5.10 (unit: V) connection: AD_CLK → P1.0 AD_DAT → P1.1 AD_CS → P3.4 analog input → CH0 (AD_DAT = DO+ DI) ADC0832 output maximum conversion value = FFH (255 ) to set the maximum measured value = 5.1V255X = 5.1 X = 0.02 which is to take 2 and then divided by 100 (the decimal point on the third digital tube) Platform: |
