I wrote a "gui" to take temperature data from a sensor connected to Arduino board, and plot it. All of that, using Arduino package support. The action start when i click "Register" push button, and it goes right, cause I give it a specific time to plot.
But, I want to extend plotting duration indefinitely, until I click a "Stop" push button. This is the code inside "registerButton" callback:
delete(instrfind('Type', 'serial'));
puerto = get(handles.portEdit, 'String');
delete(instrfind({'Port'},{puerto}));
a = arduino(puerto);
for i = 2:19
a.pinMode(i, 'input')
end
handles.a = a;
t_s = str2double(get(handles.tiempoButton, 'String'));
a_pin = str2double(get(handles.pinAnalogButton, 'String'));
escala = str2double(get(handles.scaleFactorEdit, 'String'));
Y(1) = handles.a.analogRead(a_pin)*escala;
t(1) = 0;
tic;
handles.q = false;
i = 2;
while(handles.q == false)
Y(i) = handles.a.analogRead(a_pin)*escala;
t(i) = toc;
i = i + 1;
plot(t,Y), grid on;
pause(0.01)
end
Here, "handles.q" represents the state of "stopButton". "false" means "stopButton" isn't pressed and "while" loop goes on, until I click it, so, loop ends. I would like to replace "handles.q == false" with the right code.
How can I do that?
