Hello,there

How many channels can be used for a SDADC module in single ended zero refrence mode? eight?

In CUBEMX,when I configure the channels of one SDADC module all into single-ended zero refrence mode, warning appears that there is conflict bettween channels.

Thanks in advance for any explanation.

Regards.

Hi,

Thank you. In fact,I have read manuals you mentioned.What puzzles me is if there is conflict bettwen each other when I configure all channels into single ended zero refrence mode?

From manual RM0313(page 231), it seems to me that its ok for my configuration.But how to explain the warning CUBEMX shows.

Regards.

Hi,

I confirm that all (eight) channels can be used for a SDADC module in single ended zero refrence mode. The warning appears as the 'Differential' mode can't be used for other channels.

Hi,

How many differential channels can be used in one STM32F373MCU(LQFP100)?

ST technical training documents says maximum differential inputs is 10 for all packages. But, in CubeMX?I can configure 11 channels in differential mode,that is 5 channels for SDADC1 and SDADC3,and 1 channels for SDADC2,which comes up to 11 differential channels in total.Confused about this.
