Understanding the STM32 Watchdog Timers

1. Two Types of Watchdogs in STM32 The STM32F103C8T6 has two built-in watchdogs: the Independent Watchdog and the Window Watchdog. Independent Watchdog (IWDG) Uses an internal low-speed clock (LSI, typical value 40kHz) as the time base. It cannot be stopped and can operate independently even if the CPU hangs. It is commonly used for system-level … Read more
