How to make morse code on GUI and display it on text box?

7 views (last 30 days)
Hi I got the code but I'm stuck cause it says my morse doesnt exist. Below is the coding for the morse code on GUI. The problem right now is I cant diplay the result .
I think my code might be wrong. Really need help.
function varargout = morse(varargin)
% MORSE MATLAB code for morse.fig
% MORSE, by itself, creates a new MORSE or raises the existing
% singleton*.
%
% H = MORSE returns the handle to a new MORSE or the handle to
% the existing singleton*.
%
% MORSE('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in MORSE.M with the given input arguments.
%
% MORSE('Property','Value',...) creates a new MORSE or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before morse_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to morse_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

That is only the code for the GUI
I made some modification and this is the new code
Below are the errors that it gives me

Siti - in your PB_M_Callback callback (which presumably converts the alphanumeric text to morse code), the code is
% --- Executes on button press in PB_M.
function PB_M_Callback(hObject, eventdata, handles)
% hObject handle to PB_M (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
Letter=handles.Letter
morse={'.----','..---','...--','....-','.....','-....','--...','---..','----.','-----','.-','-...','-.-.','-..','.','..-.','--.','....','..','.---','-.-','.-..','--','-.','---','.--.','--.-','.-.','...','-','..-','...-','.--','-..-','-.--','--..','/'};
NumberOrLetter={'1','2','3','4','5','6','7','8','9','0','A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z',' '};
for i=1:length(Letter);
[~, index] = ismember(Letter(i), NumberOrLetter);
if index > 0
set(handle.Morse,sprintf,'string');
end
end
I suspect that the handles.Letter is the handle to the edit text control that the user types the alphanumeric string into. Is this the case? If true, and you want to get the string you (may) need to get the string value as handles.Letter is a handle). Once found, you will want to iterate over each character in the string and convert it to the morse code equivalent. The code
set(handle.Morse,sprintf,'string');
is incorrect - you need to specify the 'String' property before the value you want to assign to it, and sprintf is a built-in MATLAB function so I'm not sure what your intent is here.
I think you could do something like
% --- Executes on button press in PB_M.
function PB_M_Callback(hObject, eventdata, handles)
% hObject handle to PB_M (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
word = char(get(handles.Letter, 'String'));
wordToMorseCode = '';
morse={'.----','..---','...--','....-','.....','-....','--...','---..','----.','-----','.-','-...','-.-.','-..','.','..-.','--.','....','..','.---','-.-','.-..','--','-.','---','.--.','--.-','.-.','...','-','..-','...-','.--','-..-','-.--','--..','/'};
NumberOrLetter={'1','2','3','4','5','6','7','8','9','0','A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z',' '};
for k=1:length(word);
character = word(k);
[~, idx] = ismember(character, NumberOrLetter)
if ~isempty(idx)
wordToMorseCode = [wordToMorseCode ' ' morse(idx)];
end
end
set(handle.Morse, 'String', wordToMorseCode);
I've haven't tested the above but i think that you get the idea. I am assuming that word can be an array of one or more characters...if it is only one character, then the code should still work. I'm also assuming that there is a 1-1 mapping in the NumberOrLetter array to morse array. So we iterate over each character in the word and check to see if it is a member of NumberOrLetter. If it is, then we append the morse code equivalent to the wordToMorseCode string. Once we have iterasted over each character, then we set this string to the handle.Morse control.
The code will be similar when converting from morse code to the alphanumeric characters...but you will need to be a bit more aware that there are multiple characters in a single morse code that needs to get mapped to a single alphanumeric character.
