ich habe die Matlab-Code für die Steuerung von Anlage geschrieben. Das Programm funktioniert. Die Aufgabe ist bei bestimmte Signale in Volt, die durch DAQ-System die Signale im Amper in SCPI-Befehl für Instrument sendet.
obj1 = instrfind('Type', 'serial', 'Port', 'COM3', 'Tag', '');
%s1=Serial('<COM1','baudrate',9600,'stopbits',1,'Terminator','
%Create the serial port object if it does not exist
%otherwise use the object that was found.
ifisempty(obj1)
obj1 = serial('COM3');
else fclose(obj1);
obj1 = obj1(1);
end
% Connect to instrument object, obj1. fopen(obj1);
Nächste Schritt ist GUI-Obelrfläche zu schreiben. Mein Code
Code:
functionvarargout = Zelle(varargin) % ZELLE MATLAB code for Zelle.fig % ZELLE, by itself, creates a new ZELLE or raises the existing % singleton*.
%
% H = ZELLE returns the handle to a new ZELLE or the handle to % the existing singleton*.
%
% ZELLE('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in ZELLE.M with the given input arguments.
%
% ZELLE('Property','Value',...) creates a new ZELLE or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before Zelle_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to Zelle_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
% Edit the above text to modify the response to help Zelle
% Last Modified by GUIDE v2.5 27-Oct-2020 20:11:20
% Begin initialization code - DO NOT EDIT
gui_Singleton = 1;
gui_State = struct('gui_Name', mfilename, ...
'gui_Singleton', gui_Singleton, ...
'gui_OpeningFcn', @Zelle_OpeningFcn, ...
'gui_OutputFcn', @Zelle_OutputFcn, ...
'gui_LayoutFcn', [] , ...
'gui_Callback', []);
ifnargin && ischar(varargin{1})
gui_State.gui_Callback = str2func(varargin{1});
end
% --- Executes just before Zelle is made visible. function Zelle_OpeningFcn(hObject, eventdata, handles, varargin) % This function has no output args, see OutputFcn. % hObject handle to figure % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA) % varargin command line arguments to Zelle (see VARARGIN)

end
Hardware is reserved (possibly by an external application). Call release to unreserve the
hardware or exit the external application, and retry the operation.
Das Fehler kommt beim Befehl
s.Background();
Wo könnte das Problem sein?
