How to decipher adc_report raw data?

PX4 Autopilot Development 👨‍💻

Board: CUAV V5 Nano
I’m trying to write short app to read ADC from (3.3V and 6.6V) pins, but have no clue on how to read/decipher raw_data from adc_report.

I tried board_adc test and got interesting numbers but have no clue (I tried giving 5V to each adc pins but didn’t find any dramatic change).

Someone please teach me how to decipher raw_data from adc_report.

After numerous testing I discovered following:
ch14’s raw_data is 3.3V ADC’s data
ch4’s raw_data is 6.6V ADC’s data

edit: Can’t promise for other boards
