Hello @istepne
This is a different issue not exactly the one mentionned on the original post. So, i've created a new one to answer you .
The ADC1_IN16 pin cannot be configured on the STM32G0B7 using STM32CubeMX without adjusting the sequencer settings in the parameter settings tab. The error message suggests that enabling this pin requires the sequencer to be set to "not fully configurable." So, you should do this to be able to use this ADC Channel.
Best Regards.
STTwo-32
