For Channel=5 and Rank=1 the result is ADC_SQR1=0xA (incorrect).
Should be 0x140.

Dear Kaouthar,
Thank you for your support.
The issue was on my side.
Of course, I modified the structure element (in main.c) by hand and did not realize that the Rank=1 corresponds to:
sConfig.Rank = ADC_REGULAR_RANK_1;
but not:
sConfig.Rank = 1;

Hello @FBaev.1 and welcome to the community 😊,
Could you please provide more details on the issue:
Make sure to use latest release of tools and last STM32Cube FW_H7 V1.11.0 firmware package.
Thank you.

Hello Kaouthar,
Thank you for the reply.
I'm using the STM32CubeIDE Version: 1.12.0 and STM32Cube_FW_H7_V1.11.0.
The board is a proprietary one based on the STM32H743ZGT6.
The issue can be observed on any evaluation board.
Possible software example is "LwIP_HTTP_Server_Raw" for STM32H743I-EVAL board.
Best regards,
Fedor

Hello @FBaev.1 ,
Thank you for this clarification.
I made some tests with Nucleo-H723ZG and I didn't find any issue and I get ADC_SQR1=0x140.
I will check again with Eval board and I will get back to you as soon as possible.
Thank you.

How exactly you obtained the ADC_SQR1=0x140?
What is the MODIFY_REG formulae in the LL_ADC_REG_SetSequencerRanks() in your test project?
Thank you,

Hi @FBaev.1 ,
> How exactly you obtained the ADC_SQR1=0x140?
The MODIFY_REG formula in the LL_ADC_REG_SetSequencerRanks() is
MODIFY_REG(*preg, ADC_CHANNEL_ID_NUMBER_MASK_POSBIT0 << (Rank & ADC_REG_RANK_ID_SQRX_MASK), ((Channel & ADC_CHANNEL_ID_NUMBER_MASK) >> ADC_CHANNEL_ID_NUMBER_BITOFFSET_POS) << (Rank ADC_REG_RANK_ID_SQRX_MASK));
Also with the STM32H757I-Eval board, with Channel=5 and Rank=1, the ADC_SQR1=0x140.
I hope this help you to solve the issue 🙂 !

I performed the same steps - i.e.
and see that ADC_SQR1=0xA .
Still not clear how:
((Channel & ADC_CHANNEL_ID_NUMBER_MASK) >> ADC_CHANNEL_ID_NUMBER_BITOFFSET_POS) << (Rank & ADC_REG_RANK_ID_SQRX_MASK)
can be evaluated for 0x140 for Channel=5 and Rank=1.
