Hi i plan new design and require activate for example on PA3 ADC1_IN4 and same time COMP2_INP.

Is this possible and if yes how sequence to setup HAL LL or direct?

EDIT: Renamed from more AF ... only one AF poss.

No. Cube is right. (here 🙂 )

See rm : setting the AF ...ONE value per pin - so its ONE AF possible . dot .

I agree one AF, but disagree many Analog. As is showed on your screens analog is always connected, next in MX you can see + GPIO_Analog not selected and this result i can set AF input capture TIM and manualy set ADC and COMP.

No.

see basic pin decision:

IF set to analog...you see yourself. 🙂
