Hello everyone,

Was wondering if you could help, I'm a bit of a newbie so this may be a very simple question.

how do i control multiple servo motors using edit text value.

Thank you

how do i make 2 outputs (slider and static text) on one pushbutton

function varargout = DESAIN_ROBOT_FULL(varargin)
% DESAIN_ROBOT_FULL MATLAB code for DESAIN_ROBOT_FULL.fig
%      DESAIN_ROBOT_FULL, by itself, creates a new DESAIN_ROBOT_FULL or raises the existing
%      singleton*.
%
%      H = DESAIN_ROBOT_FULL returns the handle to a new DESAIN_ROBOT_FULL or the handle to
%      the existing singleton*.
%
%      DESAIN_ROBOT_FULL('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in DESAIN_ROBOT_FULL.M with the given input arguments.
%
%      DESAIN_ROBOT_FULL('Property','Value',...) creates a new DESAIN_ROBOT_FULL or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before DESAIN_ROBOT_FULL_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to DESAIN_ROBOT_FULL_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

I have not done that either. Good luck.

I have tried to make a simple coding, but I have a problem when I set slider1, why do axes2 react too?

function slider1_Callback(hObject, eventdata, handles)
global s1;
slider=get(hObject,'value');
set(handles.edit1,'string',num2str(slider));
guidata(hObject,handles);
pos1=slider/180;
writePosition(s1,pos1);
y1= [0 1 0 0 ];
x1= [0 0 1 20 ];
y2= [0 1 0 0 ];
x2= [0 0 1.5 20 ];
y3= [0 1 0 0 ];
x3= [0 0 2 20 ];
i=0;
    i=i+1;
    v(i)=readPosition(s1);
    if (v(i)<0.5)
    stairs(x1,y1,'LineWidth',2);
        elseif (v(i)==0.5 || v(i)>0.5 && v(i)~=1)
            stairs(x2,y2,'LineWidth',2);
                    elseif (v(i)==1)
                         stairs(x3,y3,'LineWidth',2); 
    end
    axes(handles.axes1);
    set(gca,'XTick', 0:1:20);
    xlabel('lebar pulsa (ms)');
function slider2_Callback(hObject, eventdata, handles)
global s2;
slider=get(hObject,'value');
set(handles.edit2,'string',num2str(slider));
guidata(hObject,handles);
pos1=slider/180;
writePosition(s2,pos1);
y1= [0 1 0 0 ];
x1= [0 0 1 20 ];
y2= [0 1 0 0 ];
x2= [0 0 1.5 20 ];
y3= [0 1 0 0 ];
x3= [0 0 2 20 ];
i=0;
    i=i+1;
    v(i)=readPosition(s2);
    if (v(i)<0.5)
    stairs(x1,y1,'LineWidth',2);
        elseif (v(i)==0.5 || v(i)>0.5 && v(i)~=1)
            stairs(x2,y2,'LineWidth',2);
                    elseif (v(i)==1)
                         stairs(x3,y3,'LineWidth',2); 
    end
    axes(handles.axes2);
    set(gca,'XTick', 0:1:20);
    drawnow;

I'm not seeing any static text labels on your figure so I don't know what handles.text2 refers to. All I see are edit text boxes. Anyway, to get the edit text box and the slider/scrollbar to sync up when you change either, you can do this:

%=======================================================================
% --- Executes on button press in pushbutton1.
%  Edit field is the master value and we send that value to the slider.
function pushbutton1_Callback(hObject, eventdata, handles)
global s1;
% Get contents of the edit box.
editBoxContents = str2num(handles.edit1.String);
% Make static text label have the integer value of the edit field.
handles.text2.String = num2str(int16(editBoxContents));
% Make the slider have the same value as the edit box.
handles.slider1.Value = number; % The value before we divided it by 180.
if handles.slider1.Value > handles.slider1.Max
    handles.slider1.Max = handles.slider1.Value;
end
% Now prepare value for sending to the servo:
% Send value to servo #1.
number = editBoxContents / 180;
writePosition(s1, number);
%=======================================================================
% Change in edit field is just like pushing the button. 
%  Edit field is the master value and we send that value to the slider.
function edit1_Callback(hObject, eventdata, handles)
pushbutton1_Callback(hObject, eventdata, handles)
% --- Executes on slider movement.
function slider1_Callback(hObject, eventdata, handles)
global s1;
% Get value from slider.
sliderValue = handles.slider1.Value;
% Send the same value to edit box #1.
handles.edit1.String = sprintf('%d', round(sliderValue));
% Send the same value to static text label #2.
handles.text2.String = handles.edit1.String;
% Now prepare value for sending to the servo:
pos1 = pos / sliderValue;
number = 1 - pos1; %For position inversion
% Send value to servo #1.
writePosition(s1, number);
% Read it back.
readPosition(s1);

Repeat for the other sets of edit fields, sliders, static text labels, and buttons.
