c# - How can i use a timer in synchronization with background worker? -

i using background worker in application data hardware , updating in ui continuously. need configure hardware info it. here requirement change configuration of hardware every 2 sec , need update corresponding info in ui. how can achieve proper synchronization?

edit: here posting logic:

         worker3.workerreportsprogress = true;                 worker3.workersupportscancellation = true;         worker3.dowork += new doworkeventhandler(worker3_dowork);         worker3.progresschanged += new progresschangedeventhandler(worker3_processchanged);          dispatchertimer timer = new dispatchertimer();     private void button_click_1(object sender, routedeventargs e)     {       timer.interval = timespan.fromseconds(5);        timer.tick += timer_tick;         timer.start();          worker3.runworkerasync();    }     private void worker3_dowork(object sender, doworkeventargs e)     {        // here running infinite loop. in loop       // calling function in dll data harware. passing info  got process changed event     }        private void worker3_processchanged(object sender, progresschangedeventargs e)     {       // here updating ui information got hardware.     }      private void time_tick(object sender, eventargs )   {     if(worker3.isbusy==true)           worker3.cancelasync();      // configuring hardware new options.     // again start background worker     if(worker3.isbusy!=true)        worker3.runasync();    }
