ich werte über eine D/A Wandler Karte meine Messergebnisse in Matlab aus.
In der GUI habe ich Felder für die Variablenübergabe und einen Start und einen Stop Knopf für die Messung erstellt.
Außerdem wird auch noch ein Signal ausgegeben.
Der Stop Button sollte nun die Messung abbrechen.
Mein Problem ist nun folgendes:
Ich kann die Messung mit dem Stop Button nicht abbrechen.
Ich denke, dass es mit einer Schleife funktionieren könnte, aber ich bekomm es beim besten Willen nicht hin
Hier mein Code
Code:
functionvarargout = untitled(varargin) % UNTITLED M-file for untitled.fig % UNTITLED, by itself, creates a new UNTITLED or raises the existing % singleton*.
%
% H = UNTITLED returns the handle to a new UNTITLED or the handle to % the existing singleton*.
%
% UNTITLED('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in UNTITLED.M with the given input arguments.
%
% UNTITLED('Property','Value',...) creates a new UNTITLED or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before untitled_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to untitled_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one % instance to run (singleton)".
%
