Hello,

I'm trying to figure out where the factory-calibrated values for internal reference (Vref and Tsense) are located in STM32F10x series.

STM32L15x series have a Vrefint_cal and Tsense_cal1/2, but I can not find anything corresponding for F10x series.

The 'F1 line does not have such calibration values.

Arrgh, that was what I didn't want to read... Thanks anyway.

This F1 line is definitely poorly designed/featured when you look at it into details (what I should have done first...my mistake).

It was historically the first line, so things got refined in the newer lines.

It's still OK for the common mcu applications.
