How to create two timers in two panels within a UIFigure in MATLAB App Designer?

Good day.

May I ask how to design two timers in two separate panels (that means one panel has one timer) within the same UIFigure in MATLAB App Designer?

I have tried adding two buttons and two labels using the same command with only different values to make the timer. However, it didn't work as only one label was counting the timer.

This is the command for the first and second timer in two different buttons. How should I modify it to have two working timers?

t = timer;
            t.Period = 1;
            t.ExecutionMode = 'FixedRate';
            t.TasksToExecute = 30;
            t.TimerFcn = @(~,thisEvent) toggleButton(app);
            start(t);
 t = timer;
            t.Period = 1;
            t.ExecutionMode = 'FixedRate';
            t.TasksToExecute = 60;
            t.TimerFcn = @(~,thisEvent) toggleButton(app);
            start(t);

Hi,

You will need to create 2 different timer objects, say, t1 and t2 and start them individually on corresponding button click.

You may find below code useful.

I have declared 2 timers t1 and t2, which get created and started on button Click of buttons timerButton1 and timerButton2 respectively.

I have also created 2 helper functions i.e. updateLabel1 and updateLabel2 which will update the text in the corresponding labels.

properties (Access = public) 
        t1; % First timer object. 
        t2; % Second timer object. 
    end 

    methods (Access = public) 
        function updateLabel1(app, obj, event) 
            app.Label.Text = string(datetime); 
        end 
        
        function updateLabel2(app, obj, event) 
            app.Label_2.Text = string(datetime); 
        end         
    end 
        
function TimerButton1Pushed(app, event) 
            app.t1 = timer; 
            app.t1.Period = 1; 
            app.t1.ExecutionMode = 'FixedRate'; 
            app.t1.TasksToExecute = 30; 
            app.t1.TimerFcn = @app.updateLabel1; 
            start(app.t1); 
        end 

        % Button pushed function: TimerButton2 
        function TimerButton2Pushed(app, event) 
            app.t2 = timer; 
            app.t2.Period = 1; 
            app.t2.ExecutionMode = 'FixedRate'; 
            app.t2.TasksToExecute = 60; 
            app.t2.TimerFcn = @app.updateLabel2;
            start(app.t2); 

        end
