STM32F0xx ADC MAX Vref and Converted Value

Question asked by Gerhard on Jun 22, 2016
Latest reply on Jun 22, 2016 by Clive One
It is recommended to use DMA for multiple ADC channels, and I spent too much time trying to switch between channels manually.
So I used STM32CubeMX to get DMA working for ADC1_Channel_0 and Channe_1

It seems with 3V3 for VDDA, I read a max of 4033 out of 4096 for 12 bit ADC.
I know 3V6 is the VDDA MAX for the ADC.
How do I calculate what the ADC value should be, for a certain input voltage.
I need to have a number od set points, but to practically measure them is time consuming.
What is the actual Voltage that will cause a ADC value of 4095
(I know I can practically measure it)

Any help appreciated
