Thread Subject: GUI updation

my condition is
iam trying to run my simulink model by supply some inputs
while i tries to give inputs to simulink model actually the
outputs from that model has to go as inputs to GUI such tht
the blocks i used there is lke angular gauge ActiveX
control and knob ActiveX controls has to show the readings
accordingly to the output values tht cme from the model

GUI has to update with the runnning simulink model output
so to capture the output from simulink model to GUI

i did this


[filename, pathname] = uigetfile('*.mat', 'Pick an Mat-
file');
if isequal(filename,0) | isequal(pathname,0)
   disp('User selected Cancel')
   mycheck=0
else
   disp(['User selected',fullfile(pathname,filename)])
   mycheck=1
end
if mycheck ==1
    disp('my check value');
    %ret=load(filename);
              getStructure = load(filename);
% get the structure
              getField = cell(fieldnames(getStructure)); %
check name of structure
              getData = getStructure.(getField{ 1} )';
% get all data
              disp('get data');
              %disp(getData);
              handles.GUI_info.volt = getData(: , 2);% get
data vector column
              disp(' 2nd colmn');
                var_data=handles.GUI_info.volt(1);
              disp(var_data);
              handles.activex2.NeedleValue =var_data ;
But while iam running the GUI is updated with the last
value of simulnk output

plzzz......
can any one help me in ths ............

Hi madhavi,

when and how do you run your Simulink model, and into which
variable do you pass the output?

hi

i tried to store the output to the workspace by using a
To Workspace block from the simulnk library

so tht i can use tht variable in my GUI



>

and you want the GUI to automatically update when there is
new data in the workspace, correct?

Perhaps you can run your GUI routine (that reads the
workspace data) in a permanent loop (or once per second,
using pause). Otherwise the GUI cannot see the new data.
But I don't know if that works parallel with the simulation.
 
Or maybe you can define a callback function of the simulink
model that calls the GUI when simulation has finshed
(see "Using callback functions" of simulink help).

thanks
but ur second solution solve my problem (i.e.,Using
callback functions ) can u provide me with some example
tht it can give me an idea
regards
madhavi

in your simulink model go to "File -> Model properties",
then select "Callbacks" and click on "StopFcn". Here you
can write down some matlab code, that is executed when a
simulation has finished.
In this code you can call your GUI, maybe with an input
argument that leads to the update routine.
I don't have an example and did not test such a procedure
yet, but I hope it works.

hi

i tried wt the way u tld but it s not working
i wrote the following code in the stop callback function
%The GUI handles are by default hidden, turn them on
 set(0,'ShowHiddenHandles','on');

%Set up the arguments that will go into the gain block
event callback listener
blk = 'my_add';
event = 'PostOutputs';
listener = @update_Data;

%Create the listener
add_exec_event_listener(blk, event, listener)
so tht after the simulnk model complete simulation it thn
calls the function updata_Data()
tht calls the GUI

but iam getting errors

can u help me what could be dne

it very urgent

regards
madhavi
