Bonjour,

J’essaye de réaliser une interface graphique avec GUIDE dans Matlab. J’ai lu beaucoup de forums, y compris la FAQ de ce site sur le sujet, mais je n’arrive toujours pas à comprendre ce que je dois faire pour que ça fonctionne.

Pour le moment l’idée est de simplement pouvoir sélectionner un fichier .csv contenant notamment des dates (fonction open_protocol) et d’afficher ces dates dans une listbox (fonction protocol). Je n’arrive pas à comprendre comment gérer mes variables et les utiliser dans d’autres composantes de ma figure.

Bien sûr, je devrais utiliser les données recueillis dans le fichier .csv pour faire autre chose, mais c’est dans un second temps. Les données du fichier csv sont des dates + heures avec pour chaque date l’instruction ON ou OFF que j’envoie à mon Arduino pour allumer ou éteindre la lumière. Si j’arrive déjà à comprendre les bases de GUIDE, je pense pouvoir compléter mon projet.

Merci pour votre éclairage

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