#include "WatchDog.hpp"

WatchDog watchdog;

watchdog.init([seconds]);

[seconds] specifies the timeout period for the watchdog. If the watchdog is not "pet" within this amount of time (excluding when sleeping in Shutdown mode), the device will be reset and the IWDGRST RCC flag will be set.

watchdog.pet();

watchdog.isEnabled();

This function returns a bool, where true means the watchdog is enabled and false designates the watchdog is not running. Note: this function only returns true when that watchdog instance has started the watchdog, and will not return true when another object has started the watchdog or the watchdog has been started manually.

if(__HAL_RCC_GET_FLAG(RCC_FLAG_IWDGRST)) {
  //watchdog caused reset
}
else {
  //watchdog did not cause reset
}
__HAL_RCC_CLEAR_RESET_FLAGS(); // clears reset flags, otherwise on the next reset even though the watchdog may not have caused the reset `RCC_FLAG_IWDGRST` will still be set.
