Hello,
I have a problem with configuring some GPIO as input for the ADC4:
While they appear to be available in the documentation (and in the pop-up window associated with GPIO), the choice is grayed out in the tab associated with ADC4.
I'm using STM32CubeMx version 6.13.0 (but it's the same with previous versions).
Is this a bug or did I forget something?
Sincerely,
Jean-Louis

Hello @JVERN.18
As mentioned in the screenshot below, channel IN22 is only available if the sequencer is not fully configurable. Therefore, you can configure ADC4_IN22 as well.
Thx,

Hello,
Do you mean for STM32U5F7, the the channels from 15 to Channel 23 + VDAC_OUT1 are grayed out?

Thank you for your response.
I didn't stay on the checkboxes long enough to see the message.
Furthermore, I don't really understand why in one case we can have access to all the inputs and why in the other this is not the case (and I did not find a super clear answer in the documentation), but I realize that it is like that!
Thanks again.
