Running example of how to use the Arduino watchdog timer - bkolicoski/Arduino-Watchdog-Timer-Example
Here is a way to work with the internal Arduino WatchDog timer. First of all, theWtoof all the Arduino models is a MAXIMUM of 8 seconds. Keep that in mind. Having a longerWtocovers a lot more sins in my opinion (Wto is 16 seconds on the internalRaspberry Pi WatchDog– which still ...
Three letters jumped out at me: WDT, the watchdog timer. Something in this example sketch is taking too long to do its thing, causing the system to believe it has locked up and needs a reset to recover. One unusual aspect ofssd1305testcode is that all work live insetup()leaving an e...
有三个接地引脚:GND.1,在板的顶部,在引脚13旁边,GND.2/GND.3在底部。 引脚VIN/5V连接到正电源。 模拟中没有引脚3.3V / IOREF / AREF / RESET。 数字引脚3、5、6、9、10和11支持硬件PWM。 一些数字引脚还具有额外的功能: 板载LED 主板包括四个LED: 一般来说,只有“L”LED才能由用户的代码控制。您...
Turn off the Watchdog Timer Straightforward but first remember to unset the flags which are set on Reset. #include <avr/wdt.h> MCUSR = 0; wdt_disable(); Turn off power to peripherals Set bits in thePRR(Power Reduction Register)
Arduino library to use the watchdog timer for system reset and low power sleep. - adafruit/Adafruit_SleepyDog
Watchdog period options: WDTO_15MS WDTO_30MS WDTO_60MS WDTO_120MS WDTO_250MS WDTO_500MS Note that Timer resolution is affected by integer math division and the time slice selected. Trying to measure 100ms, using a 60ms time slice for example, won't work. ...

watchdog timer in the ESP8266 that will reset the processor if you keep it busy too long. More on that in a future posting. Put lots of yield() or delay(0) statement in your program to keep this from happening. Note, delays with values greater than zero (delay(10) for example) ...
