STM32 has 2 watchdogs: independent watchdog and window watchdog. Independent watchdog IWDG: A system fault detector that is independent of the system and is not affected by the system because it has ...[Details]
The calculation formula of the watchdog feeding time (watchdog overflow time) is: Tout=((4*2^prer)*rlr)/40 Tout is the watchdog overflow time (in ms), prer is the watchdog clock prescaler value (...[Details]
The pins of stm32 have two uses: GPIO (general purpose io) and AFIO (alternate function io) For some pins (depending on the chip), neither of these two uses exists. For example, in 64-pin products, O...[Details]
