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)".
