Estoy realizando mi tesis de fin de grado, mi problema es que tengo que capturar datos con un pic y mandarlos por usb a la pc (esto funciona), luego quiero graficar los datos que recibo en una gui pero grafica al final de la adquision de los datos.
Aca cito el codigo:
function varargout = prueba_gui(varargin)
% PRUEBA_GUI M-file for prueba_gui.fig
% PRUEBA_GUI, by itself, creates a new PRUEBA_GUI or raises the existing
% singleton*.
%
% H = PRUEBA_GUI returns the handle to a new PRUEBA_GUI or the handle to
% the existing singleton*.
%
% PRUEBA_GUI('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in PRUEBA_GUI.M with the given input arguments.
%
% PRUEBA_GUI('Property','Value',...) creates a new PRUEBA_GUI or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before prueba_gui_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to prueba_gui_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
