[嵌入式/单片机/硬件编程] 独立看门狗实验

STM32 的独立看门狗由内部专门的 40Khz 低速时钟驱动,即使主时钟发生故障,它也仍然有效。 看门狗的原理:单片机系统在外界的干扰下会出现程序跑飞的现象导致出现死循环,看门狗电路就是为了避免这种情况的发生。看门狗的作用就是在一定时间内(通过定时计数器实现)没有接收喂狗信号(表示 MCU 已经挂了),便实现处理器的自动复位重启(发送复位信号) 。
The STM32's independent watchdog is driven by an internal 40Khz low speed clock, and it is still valid even if the main clock fails. (2018-03-27, C/C++, 2606KB, 下载2次)
