Using the WWDG of STM32F030, it is found that the MCU will not be reset under STOP, just like the sleep mode of STM8S. Paste the watchdog code: /******************************************************...[Details]
Independent watchdog (IWDG) and low power mode are often used in STM32 development. The watchdog is to detect and solve faults caused by software errors, and the low power mode is to enter sleep mode...[Details]
Why does MCU have a watchdog? With this question, let's learn about watchdogs. Even the 51 single-chip microcomputer has a watchdog, which shows that this dog has a special meaning to us. The purpose...[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]
