//#define USE_WATCHDOG
#ifdef USE_WATCHDOG
// you cannot watchdog reboot on Arduino mega2560 due to a bug in he bootloader. Hence we need to ask the user to reset.
// THIS FEATURE IS UNSAFE!, as it will only work if interrupts are disabled. And the code could hang in an interrupt routine with interrupts disabled.
//#define RESET_MANUAL
// If you have a watchdog reboot in an ArduinoMega2560 then the device will hang forever, as a watchdog reset will leave the watchdog on.
// The "WATCHDOG_RESET_MANUAL" goes around this by not using the hardware reset.
// However, THIS FEATURE IS UNSAFE!, as it will only work if interrupts are disabled. And the code could hang in an interrupt routine with interrupts disabled.
