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
