Differential ADC

[Giovanni]

Hi,

I added the feature to the trunk code. The DIFSEL register initialization value is now part of the ADCConfig structure.

Hi,
what was the intention to add it to the ADCConfig type and not to the ADCConversionGroup? Now the ADC features are divided into two separate structures.

Hi,

Does it make sense to have conversion groups with and without the differential settings for the same board? The differential mode is something that is wired at board level so I thought that it can be a global setting.

Hi,
it depends on the application you want to implement. May there is one where you want to measure two channels in differential mode and then switch to single-ended due to a certain condition of your application. I don't know an exact example.

Hi,
Is this feature available on STM32F407-Discovery? If it is, would somebody help how to enable it?
Many thanks

It is specific of the STM32F3xx.
