Matlab - exit infinite while loop with a keypress

This code is for an infinite while loop in Matlab, it will check to see if the 'q' key has been pressed, it when then ask do you really want to quit (Yes/No) and then exit the while loop.

 

close
clear all
clc
figure('doublebuffer','on', ...
       'CurrentCharacter','a', ...
       'WindowStyle','modal')

t=text(.5,.5,datestr(now),'Hor','center');

while (1)
    
    % your code here
    set(t,'String',datestr(now));
    % your code ends 
       
    pause(.01); % added to pause and allow screen/ keyboard buffer to update

    if double(get(gcf,'CurrentCharacter')) == 113 % check if 'q' key pressed, change to 27 for escape
        choice = menu('Quit code yes or  no?','Yes','No');
        if choice==1 | choice==0
            break; % break from while loop
        end
        set(gcf,'currentch',char(1)) % Sets current char as 1 or it would just keep asking to quit
    end
   
end

set(t,'String','While loop exited, finished');
set(gcf,'WindowStyle','normal');

 

How to update National Instruments myRIO firmware and Real-Time

The National Instruments myRIO requires to have the same Real-Time module  installed on as the one that is installed  with LabVIEW to be able to use, if an old version is installed on the myRIO then when you plug the myRIO in the "NI myRIO USB monitor" will disable LabVIEW from the menu (see fig 1), if you are using the latest version of LabVIEW then you will need to update the firmware* or use an older version of LabVIEW.

* Updating the firmware will delete all code installed on the myRIO.
