看门狗,又叫 watchdog timer,是一个定时器电路, 一般有一个输入,叫喂狗,一个输出到MCU的RST端,MCU正常工作的时候,每隔一端时间输出一个信号到喂狗端,给 WDT 清零,如果超过规定的时间不喂狗,(一般在程序跑飞时),WDT 定时超过,就回给出一个复位信号到MCU,是MCU复位. 防止MCU死机. 看门狗的作用就是防止程序发生死循环,或者说程序跑飞-Watchdog, called watchdog timer, a timer circuit, generally have an input, called feed the dog, an output to the MCU s RST terminal, MCU normal work time, every time one end of the output a signal to feed the dog end to WDT clear, if not feed the dog more than the stipulated time, (usually when Runaway), WDT time over, went back to give a reset signal to MCU, MCU is reset. to prevent the MCU crash. watchdog role program is to prevent infinite loop occurs, or Runaway
