基于MATLAB GUI界面的串口助手

function varargout = SerialGUI2(varargin) % SERIALGUI2 MATLAB code for SerialGUI2.fig % SERIALGUI2, by itself, creates a new SERIALGUI2 or raises the existing % singleton*. % % H = SERIALGUI2 returns the handle to a new SERIALGUI2 or the handle to % the existing singleton*. % % SERIALGUI2('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in SERIALGUI2.M with the given input arguments. % % SERIALGUI2('Property','Value',...) creates a new SERIALGUI2 or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before SerialGUI2_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to SerialGUI2_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu.
