I am using STM32L432KBU6 controller in my design. I want to Monitor battery voltage on ADC pin using Voltage divider.
LiPo battery ratings is 3V to 4.2V.Any reference circuit than please share.I want to learn exact calculation for ADC.There are various values of RAIN mention in table 63 of datasheet.Should i use same values for Resistor Divider?How much counts i can...
