How to convert raw values to voltage?
The formula for converting ADC to voltage is:
[ ADC * (1.8/4096) ] / 2000
This is due to a 2000x gain, 4096 ADC range, and 1.8V input voltage to the ADC.
Please note the gain on actual hardware may be slightly off from 2000 (maybe +/- 5%?), but unless you need to make ultra-sensitive measurements for some reason, that formula should be good enough.
