Watchdog

A watchdog timer is used to reset the system if the system fails or locks up.

It is recommended to run the watchdog inside a thread in the application.

Max timeout is 131 seconds.

.NET

using GHIElectronics.Endpoint.Core;
using GHIElectronics.Endpoint.Devices.Watchdog;

using var watchdog = WatchdogController.FromName(EPDomino24.Watchdog.Id);

watchdog.Enable(TimeSpan.FromSeconds(10));   // 10 seconds
var cnt = 0;
while (true) {
    Console.WriteLine("cnt: " + cnt++);
    Thread.Sleep(1000);

    watchdog.Reset();
}

Python

import datetime, time
from GHIElectronics.Endpoint.Core import EPDomino24
from GHIElectronics.Endpoint.Devices.Watchdog import WatchdogController

watchdog = WatchdogController.FromName(EPDomino24.Watchdog.Id)

watchdog.Enable(datetime.timedelta(seconds=10))   # 10 seconds
cnt = 0
while True:
    print("cnt:", cnt)
    cnt += 1
    time.sleep(1)

    watchdog.Reset()
