To enable each gauge block to flash independently without interruption, we can use "timer" objects. This allows asynchronous execution, meaning each block can handle its flashing behavior separately from others. When a block's value exceeds a specified threshold, its timer will trigger, causing the block to flash red. This ensures that multiple blocks can flash simultaneously without interfering with each other.
Here's how you can do it:
% Define the function to handle value changes for Item1
function Item1ValueValueChanged(app, event)
value = app.Item1Value.Value;
app.Item1Gauge.Value = value;
% Stop the timer if it's already running
if isfield(app, 'Item1Timer') && strcmp(app.Item1Timer.Running, 'on')
stop(app.Item1Timer);
end
% Create a new timer
app.Item1Timer = timer('ExecutionMode', 'fixedRate', ...
'Period', 0.1, ...
'TimerFcn', @(~,~) TimerCallback(app, 'Item1', value));
% Start the timer based on the value
if value > 120
start(app.Item1Timer);
elseif value > 100
%%
else
% Reset the background color
app.ItemBlock.BackgroundColor = [0.5, 0.5, 0.5];
end
end
% Define the timer callback function
function TimerCallback(app, item, value)
% Determine which block to update
switch item
case 'Item1'
handle = app.ItemBlock;
% Add cases for other items as needed
end
% Flash red
persistent toggle;
if isempty(toggle)
toggle = false;
end
toggle = ~toggle;
if toggle
handle.BackgroundColor = [1, 0, 0]; % Red
else
handle.BackgroundColor = [0.5, 0.5, 0.5]; % Default
end
% Stop the timer if the value is within the normal range
if value <= 120
stop(app.Item1Timer);
handle.BackgroundColor = [0.5, 0.5, 0.5]; % Reset color
end
end
