Opta Hardware Watchdog

Does anyone know if the Arduino Opta RS485 has a hardware watchdog to reset the CPU in case the user program becomes unresponsive?

Thanks in advance!

Hi, same MCU as the GIGA so you can try:

mbed::Watchdog &watchdog = mbed::Watchdog::get_instance();

void setup() {
...
  watchdog.start(timeout_in_ms);
}

void loop() {
...
  watchdog.kick();
}

Once started, it cannot be stopped but you can change the timeout with another call to .start()
