I wanted to read the input voltage on VP-AUX1 pins via I2C. I came across the below formula to calculate the voltage on the pins
V = (ADCCode / 4096)
× Attenuation Factor × VREFIN
I was wondering what is the adc code here? Is the ADC values from the below registers ADC Value registers from Table 17.
VP1 0xA0 ADCHVP1 7:4 N/ANot used if 0x82[2] (average) = 0.
0-3 OUT3 to OUT0
R/W 4 MSBs of 12-bit result of ADC conversions on VP1 when 0x82[2] (average) = 0.
7-0 OUT7 to OUT0
I am reading the values from this and trying to calculate but the calculated voltage appears to be wrong.
Please help.
