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(kicking the dog or service the dog),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,就会给出一个复位信号到MCU,是MCU复...
越省电的模式,仍在运作中的模块就越少。 例如,在”Power-Down”(电源关闭)睡眠模式之下,微控器仅剩下外部中断和看门狗定时器(Watchdog Timer,参阅下文说明)仍持续运作。而在Idle睡眠模式底下,SPI,UART(也就是序列端口)、定时器、模拟数位转换器等,仍持续运作,只有中央处理器和闪存(Flash)时脉信号被停止。 时脉...

Normally, the ATmega Watchdog Timer is used to generate 15ms time slices (Ticks). For applications requiring high precision timing, the Ticks can be sourced from a hardware timer or external clock. See chapterScheduler Tick Sourcesfor the configuration details. ...
The AVR Watchdog Timer is used to generate 15ms time slices, but Tasks that finish before their allocated time will hand execution back to the Scheduler. This does not affect the use of any of the normal Timer functions in Arduino.
