GUI red circle indicating connection
显示 更早的评论
I have serial connection. I would like to have a green circle blinking in the screen while connection is on and a red circle while connection is off.
do i need to use axes for that?

Personally I would do it with axes yes. Below an example of green and red circle depending on parameter x.
x = [0 1];
for i =1:numel(x)
rectangle('Position', [0.0 0.0 1 1], 'Curvature', [1 1], 'FaceColor', [x(i) 1-x(i) 0]) % with x = parameter
ax = gca;
% remove tick labels
set(ax,'XTick',[]),set(ax,'YTick',[])
% make lines of the axes white --> invisible on white background
set(ax,'XColor',[1,1,1]) , set(ax,'YColor',[1,1,1])
% make axes square to get round circle
axis square
pause(0.5)
end
Kind regards,

x is your variable. In your case wether the connection is on or off. You should make axes in your GUI and implement code in your GUI code that checks if the connection is on and then update the axes by updating the variable 'x' first.

I believe you need something like this and adjust the function to make it change the color of the circle to white. I never used it before so good luck. I also read if you are doing heavy caculations the timer will not do its function in the background but it will do its task whenever some time is available.
t = timer;
t.ExecutionMode = 'fixedRate';
t.Period = 1;
t.TimerFcn = @(~,~)disp('1s elapsed');
start(t)
Good luck,
