關于stm32f4與Matlab串口通信 Matlab文件

源程序如下:

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