Stm32 ADC Calculation

Read the pin voltage value from the ADC with the STM32, how to convert the data read back to the value of V???

V (ADC) = Value (ADC) * V (ref)/4096
(The Stm32 ADC is 12 bits, so the maximum ad Word is 4096) where V (ADC) is the calculated voltage value, and value (ADC) is the captured ad value, and V (ref) is the reference voltage, typically 3.3V. For example, your STM32 reference voltage is 3.3v, the captured ad value is 1024, then convert to voltage V (ADC) = 1024x3.3/4096 = 0.825V
