How to properly implement external 32.768 kHz crystal for accurate RTC on STM32F407VGT6?
Hi STM Community,I am using a custom board based on the STM32F407VGT6 MCU. Currently, I’m not getting accurate RTC time when using the internal LSI clock (the drift is too high for my application). So I’ve decided to use an external 32.768 kHz crysta...
