The independent watchdog of STM32 is driven by a dedicated internal 40Khz low-speed clock, that is, it is still effective even if the main clock fails. Here we need to note that the clock of the inde...[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]
