Reading Battery Voltage with the STM32''s ADC
The returned value is on a scale of 0 – 4095, because it is a 12-bit ADC. A value of zero means that the ADC reads zero volts, and a value of 4095 means that the ADC reads the supply voltage, which is 3.3V in this case. Since the voltage divider cuts the battery''s voltage in half, we can calculate the total voltage with this equation:
