在操的時候，模塊會返回數據到串口通過讀取串口的數據，分析模塊的運行。利用matla讀取串口數據的能力，并加上其強大的繪圖能力，可以讓數據更為直觀的可視化，便于用戶更加了解這個模塊的運行情況，方便調試。

- function varargout = comtest2(varargin)
- % COMTEST2 MATLAB code for comtest2.fig
- % COMTEST2, by itself, creates a new COMTEST2 or raises the existing
- % singleton*.
- %
- % H = COMTEST2 returns the handle to a new COMTEST2 or the handle to
- % the existing singleton*.
- %
- % COMTEST2('CALLBACK',hObject,eventData,handles,...) calls the local
- % function named CALLBACK in COMTEST2.M with the given input arguments.
- %
- % COMTEST2('Property','Value',...) creates a new COMTEST2 or raises the
- % existing singleton*. Starting from the left, property value pairs are
- % applied to the GUI before comtest2_OpeningFcn gets called. An
- % unrecognized property name or invalid value makes property application
- % stop. All inputs are passed to comtest2_OpeningFcn via varargin.
