Hello,
I'm using an ST32U5 microcontroller and I'd like to ask some question about the ADC linear and offset calibration feature.
1 - This feature is only available on ADC1 or is it also available on ADC4?
2 - Right now at startup I'm launching the ADC1 calibration with the following parameter :ADC_CALIB_OFFSET_LINEARITY. Does this calibrate both the offset and the gain?
3 - Is there some issues (except for a longer startup time) in launching the calibration every time at startup?
Thank you
Matteo

The ADC4 has only offset calibration, see page 1084 in RM0456 Rev 3
The ADC1 can do both, and ADC_CALIB_OFFSET_LINEARITY
should calibrate offset and linearity.
