MATLAB gui timer function callback problem

Hi,

I'm trying to use a timer in my matlab GUI that calls a function. Passing the handle for the function is causing me issues. Can someone help me with where I'm going wrong in this code?

I'm getting the following error:

Error while evaluating TimerFcn for timer 'timer-1' 

Not enough input arguments.

The timer is initialized in the open function for the GUI like so:

function Control_Window_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% varargin   command line arguments to Control_Window (see VARARGIN)

% Choose default command line output for Control_Window

handles.output = hObject;

guidata(hObject, handles);
handles = guidata(hObject);
sda = handles.auto_read;
autoread_timer = timer('TimerFcn', {@(hObject, eventdata, handles)auto_read_Callback}, 'Period', 1,'ExecutionMode', 'fixedRate');

start(autoread_timer);

And the function that is accessed with the callback is:

function auto_read_Callback(hObject, eventdata, handles)
% hObject    handle to auto_read (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

set(handles.auto_read,'BackgroundColor',[0 1 0]);
set(handles.tabA,'BackgroundColor',[0.7 0.78 1]);
set(handles.tabB,'BackgroundColor',[0.7 0.78 1]);
set(handles.tabC,'BackgroundColor',[0.7 0.78 1]);
set(handles.tabD,'BackgroundColor',[0.7 0.78 1]);

if (get(hObject,'Value'))

      data=get(handles.Table1,'data');
      for x=1:size(data)
          if data{x,4}==1
              temp = data{x,1};
              string1 = 'struct.';
              string2 = strcat(string1,temp);

              actualvalue = evalin('base', string2);
              data{x,5}=actualvalue;
              set(handles.Table1,'data',data)       

          else
        ; 
          end
      end
  end
  set(handles.auto_read,'BackgroundColor',[0.831 0.816 0.784]) ;

Any help would be appreciated

You can use

function auto_read_Callback(obj,event,hObject,eventdata)
handles = guidata(hObject);

instead of

function auto_read_Callback(hObject, eventdata, handles)
