I have this code that I have bult that compares a string coming over serial data to one that is stored in an excel file. A correct match makes a panel in the GUI go green, and red when they are not matched.
This is the code I have as of now:
function varargout = WorkingGUI2(varargin)% WORKINGGUI2 MATLAB code for WorkingGUI2.fig
% WORKINGGUI2, by itself, creates a new WORKINGGUI2 or raises the existing
% singleton*.
%
% H = WORKINGGUI2 returns the handle to a new WORKINGGUI2 or the handle to
% the existing singleton*.
%% WORKINGGUI2('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in WORKINGGUI2.M with the given input arguments.
%% WORKINGGUI2('Property','Value',...) creates a new WORKINGGUI2 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before WorkingGUI2_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to WorkingGUI2_OpeningFcn via varargin.
%% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

I don't know If have correctly made or called the functions in this script. I chnaged the handles monikor becasue I got a warning that it was used multiple times ( I don't know if that was necessary). When running the program, the GUI comes up jsut as I want it, but then get this error:
matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)WorkingGUI2('uipanel1_CreateFcn',hObject,eventdata,guidata(hObject)) Undefined function or variable 'WorkingGUI2_OutputFcn'.Error in gui_mainfcn (line 264) feval(gui_State.gui_OutputFcn, gui_hFigure, [], gui_Handles);Error in WorkingGUI2 (line 42) gui_mainfcn(gui_State, varargin{:});
I don't think I need any arguments output from WorkingGUI2_Outputfcn, but I am not sure.
thanks for any help
