Problem configuring ADC4 inputs with STM32CubeMx 6.13.0

JVERN.18 · ‎2024-11-27

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,

Souhaib

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.
