Conclusion

The STM32F10xxx RTC digital clock calibration feature allows the user to adjust the clock

accuracy during manufacturing (or later) at minimal cost. This feature also provides a

method whereby “drift” (due to temperature variation) can be corrected and/or anticipated.

However, the method described in this application note is applicable only if the RTC

prescaler is set to 32 766 (instead of 32 768).
