Matlab 串口通信GUI

function varargout = COM(varargin) % COM MATLAB code for COM.fig % COM, by itself, creates a new COM or raises the existing % singleton*. % % H = COM returns the handle to a new COM or the handle to % the existing singleton*. % % COM('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in COM.M with the given input arguments. % % COM('Property','Value',...) creates a new COM or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before COM_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to COM_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one % instance to run (singleton)". % % See also: GUIDE, GUIDATA, GUIHANDLES % Edit the above text to modify the response to help COM % Last Modified by GUIDE v2.5 05-Mar-2019 17:28:05 % Begin initialization code - DO NOT EDIT gui_Singleton = 1; gui_State = struct('gui_Name', mfilename, ...
