- Reference
- Detailed Descriptions
The standard watchdog on an AVR processor has a maximum period of 8s without a reset of the watchdog clock before the processor is restarted.
Code for this is taken from this forum post: https:/
Public static variables
- static volatile uint32_t _barksUntilReset
- The number of times the pre-reset interrupt is allowed to fire before the watchdog reset is allowed.
Constructors, destructors, conversion operators
- extendedWatchDogAVR()
- Construct a new extended watch dog object for AVR processors.
- ~extendedWatchDogAVR()
- Destroy the extended watch dog object for AVR processors.
Public functions

- One-time initialization of watchdog timer.
- void enableWatchDog()
- Enable the watchdog.
- void disableWatchDog()
- Disable the watchdog.
