- Tue Apr 28, 2015 12:43 am #15874 Just curious if anyone has used the watchdog timer with this IDE? I have tried #include <avr/wdt.h> but when compiling it gives an error of: fatal error: avr/wdt.h: No such file or directory.

Use

Code: Select allextern "C" {
#include "user_interface.h"
}

and you should be able to use the watchdog . Delete the ref. to <avr/wdt.h>( this is for Atmel micros only ,not the ESP8266)

- Tue Apr 28, 2015 9:22 pm #15960 Ok good, I am already using that to track heap size.

Would I just enable watchdog by putting ESP.wdtEnable(WDTO_4S) in setup for example to have watchdog reset in 5 seconds if no ESP.wdtFeed() is seen in that time?
