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
digital tube)

Description: 本文将总结我们公司所设计的各种电源电路，从中提炼出我们公司的电源平台，供大家参考。
我们通常用到的工作电压为12V和5V。12V主要用来驱动继电器工作或蜂鸣器，在本平台中将用＋12表示；5V将用＋5表示。在应用中，也用到24V和3V电源，分别用＋24和＋3表示。3V一般用在有电池做备用电源的场合。
-This paper will summarize our company designed the power supply circuit, from which we extract the Power platform, for your reference. We usually use the working voltage of 12 V and 5 V. 12V Relay mainly used to drive to work or buzzer sounded, in this platform will be used+12 said. 5V will be used+5 said. In this application, also applied to 24 V and 3 V power supply, and were used+24+3 said. 3V is generally done in a standby power batteries occasions.
