ADC different channel, same value

[carlesls2]

 

 

 

 

I am just wondering how it is possible that 3 adc gave me the very same value, if I change the channel and their rank are different.   

Thanks for all.

Are they all connected to the same thing?

When converting a single channel in fully configurable mode, rank 1 is the only channel converted.

Two of your three pictures are the same. The other one configures rank 3 which isn't converted.

Almost the same value...

I was just wondering... If an adc is burned inside a stm32g051g8,  should all the values that the ADC from different channel be the same or quite similar?

 

 

Thanks for all.
