Hello, I am going to use the internal RTC. However, there are a lot of errors when using the internal RTC. I wonder if there is a way to reduce errors.I don't know because I'm a beginner. Thank you for giving me a detailed answer.
there are a lot of errors when using the internal RTC
What kind of errors?
Hi HG LEE ,
1- What are you using as STM32 product?2- What are exactly the problems you faced with RTC?
3-Could you please provide more explanation on your case, so that it will be easier to understand the issue?
2.3-I would like to use internal rtc when I can't use external rtc.But I don't know how to hold the internal rtc.
In short, I wonder if we can reduce the internal rate of internal error rates.

For precise timekeeping, you need to have connected a 32.768kHz crystal to the LSE oscillator pins, LSE enabled, and if you want to maintain time while the whole chip is powered down, you need to have a battery connected to VBAT.
Dear HG LEE,
can you please share with us what errors you have? We would like to understand more what rates of errors you are talking about.
Thank you for your cooperation.
