How to calibrate RTC on STM32F411CEU6
2023-10-02
Hello everyone! I have stm32f411ceu6 dev board, and I decided to use RTC. But it's going slower than time on reference clock. I use 32768 oscillator, which is soldered on the board. Can I calibrate this thing?

I use STM32CubeMX and PlatformIO. But I think it cannot be a reason. And I don't use any power saving modes

Thanks for your answer! In half an hour, the RTC fell behind by 5 minutes.
