Description: 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)
