[MATLAB] Répéter en fin de programme un but de code

L’auteur de ce sujet a trouvé une solution à son problème.

Bonjour,

Je poste ce message car j’ai un petit problème sur MATLAB : je suis entrain de faire une interface homme machine communiquant entre MATLAB et Arduino. J’ai réussi à faire la partie MATLAB vers Arduino mais je n’arrive pas à faire l’inverse, je sais comment faire grâce à ça : http://allaboutee.com/2011/07/04/how-to-send-data-from-the-arduino-to-matlab/ mais je n’arrive pas à l’implémenter dans mon cas…

En faite j’aimerais ajouter à la fin de mon programme (que vous trouverez ci dessous) une fonction qui s’executeras disons toute les 1 secondes et qui contiendrais toute les manipulations concernant la partie MATLAB vers Arduino (vérification si Arduino envoie quelque-chose, si oui récupérer ce quelque chose etc…).

Sauriez-vous comment faire ?

Cordialement et Merci d’avance !

Jupiter41.

EDIT : En faite une autre petite question secondaire :) : Connaîtriez-vous la valeur du retour de fread(arduino, 'Value’) si Arduino n’envoie aucune valeur ? -1, peut-être ?

Mon programme :

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