Hello ST All.
I have a NUCLEOL476RG and i have some troubles trying to read a battery level using ADC.
I made a voltage divider partitor to get 3.3V starting from 14.1V.
1) using 162K resistor + 50K resistor the adc read 2.9v
2) using 68.8k + 20.78k the adc read 2.6v.
Using multimeter on partitor in both read 3.20v .
If i read 3.3 from Nucleo (CN7 pin 2 or 4) adc read correctly.
please, Anyone may helm me with hints?
