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]

The STM32 watchdog has two WWDG and IWDG. The biggest difference between the two is that IWDG has only one lower limit for feeding, while WWDG, as the name implies, must be fed within a range to ensu...[Details]

A crystal oscillator can be electrically equivalent to a two-terminal network consisting of a capacitor and a resistor in parallel and a capacitor in series. In electrical engineering, this network h...[Details]
