How to display continuous changing values in static text of GUI

here i am receiving values from serial port and then i am separating text part from received data.

when i separate text, then i need to display in static text on GUI. here i used code which displays the value after completing the loop. here i considered loop is 6 times, it means i am reading 6 values from serial port.but it will display only last value(after completing loop).

Here is the push button code please any one tell me what to modify.

function pushbutton1_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
delete(instrfindall)
ser=serial('COM4','BaudRate',9600);
fopen(ser)
count=0;
for i=1:6
  da=fscanf(ser);
  cond=isempty(da);
  if cond==0
      count=count+1;
  end
  if count==3
      set(handles.text1,'string',da);
      count=0;
  end
end

Did you got your code to work?

If so, is it possible to share the code? I'm working on a similair project but I'm having a hard time to figure out where to start.

Kind regards.

Change the last condition

if count==3
    str=get(handles.text1,'string')
    set(handles.text1,'string',[str da]);
    count=0;
end

Thank you Azzi,

my received data not in same length and i want to display only current received text,but it is appending with previous text.

if received data is more than 3 times it giving error like

CAT arguments dimensions are not consistent.

I think your code is working fine. Try putting a little time delay before setting the string of handles.text1. Something like,

if count == 3
  pause(1) ; % 1 second time delay
  set(handles.text1,'string',da);
  count=0;
end
