I have a code that is working fine using WatchDog timer to auto reset in case something goes wrong, but now i got a arduino with ATMega328PB, and the old code just don't active the watchdog.

#include <avr/wdt.h>
wdt_enable(WDTO_8S);
for(int i = 0; i < 10; i++)
{
    delay(1000);
}

This is the code to test, but the reset that should happen just doesn't happen.

In the datasheet say that the watchdog still there to use, but i have no idea how to active it now.

have a look at some of the tutorials that are available on the web – jsotola Jul 01 '23 at 22:15
I didn't find no tutorials for the 328PB model – Christian Beregula Jul 03 '23 at 13:50

I already saw the example in the datasheet, but I couldn't compile it, is there any other option? – Christian Beregula Jul 03 '23 at 20:58
couldn't compile it ... what does that mean? ... what error did you get? – jsotola Jul 03 '23 at 22:45
For example __watchdog_reset(); there are 3 functions that I don't know how to replace or implement to keep the code functional, and there is also how to set the watchdog time – Christian Beregula Jul 06 '23 at 20:10
