It makes sense to clock it with sources that are independent of VDD: LSE or LSI. The LSI is independent from the high speed clocks and very useful for the IWDG (Independent Watchdog), but very inaccurate. So use the LSE if you need some accurate and predictable clock. iterate row by row pandas

WebMay 26, 2024 · The STM32 RTC locks (freezes) the RTC when you read the time register and un-freezes it when you read the date register. This is done to protect you from the situation where you read the time just before midnight (e.g. 23:59:59) and then the RTC date rolls over to the next day before you read it which would result in an off-by-one-day error.
