Watch Dog Timer

#include <MsTimer2.h>

volatile long wdt_prev_millis=0;
volatile long wdt_cur_millis=0;

void(*resetWdt)(void)=0;

void updateWdt()
{
wdt_cur_millis=millis();
if(wdt_cur_millis-wdt_prev_millis>=1000)
{
//turnOffEsp();//If using esp
resetWdt();
}
}

void initWdt(long duration)
{
MsTimer2::set(duration, updateWdt);
MsTimer2::start();
}

void clearWdt()
{
wdt_prev_millis=millis();
}

void turnOffEsp()
{
digitalWrite(PIN_ESP_IO0, LOW);
digitalWrite(PIN_ESP_EN, LOW);
}

void setup() {
Serial.begin(9600);
Serial.println("hi");
initWdt(2000);
}

void loop() {
while(1)
{
//clearWdt();
}
}


Should i use this or any proper method available?

Hi jihas,

Did you find another sample codes? Or your code is already fine for your application?

The code is working.If using IDE4GR include "mbed.h", in WdtStats BIT7 will give an error in ide4gr .To fix this, initialise uint16_t BIT7=0x0040;
