In the STM32 H7 HAL driver (UM2217) there is the following function:It is absolutely not clear for me that what is the difference between ADC_CALIB_OFFSET and ADC_CALIB_OFFSET_LINEARITY?Thank you in advance

Hello everyone,I am using an STM32H723ZG MCU and wanted to use ADC scan conversion with DMA. I could implement what I wanted there is just one thing I do not fully understand related to it.I am using ADC3 whose maximal resolution is 12 bit. Based on ...

Hello everyone,I have a NUCLEO-H723ZG board and its user manual UM2407 does not contain its schematic. Is there a way to have a look at the board's schematic somewhere?Thanks in advance

@omuzychko Thank you very much for debugging the issue! It helped me so much!I have a NUCLEO-H723ZG board and I can confirm that the Ethernet was the cause of the extremely noisy ADC measurements in this case as well. After tombstoning the L1 ferrit...

However, if ADC_CALIB_OFFSET only corrects your offset error but ADC_CALIB_OFFSET_LINEARITY corrects both your offset + gain error, then why do you have these two choices? I mean, you could simply just use ADC_CALIB_OFFSET_LINEARITY option all the ti...

Indeed, you are absolutely right. Thank you for your answer.

Yes, it did help, thank you. Based on the example you referenced I could understand what I was doing in a wrong way and fix it. Just one last question: Why is the ALIGN_32BYTES needed? It works for me even without it.

Hi @RomainR. ,Yes, I can choose Byte or Half-Word as well. However if I do so, then my ADC results are not transferred from peripheral to memory properly. Maybe I should have asked my question in a more general way. I could look at the MemDataAlignm...
