I have some question on obtain data from arduino which connect to optical encoder. I have using following code to obtain data from Arduino
function encoder1pushbutton9_Callback(hObject, eventdata, handles)
handles.a.pinMode(2,'input');
handles.a.digitalRead(2)
numberOfDatas = 200;
data = zeros(1, numberOfDatas);
i = 1;
% Main graph figure
figure(1);
hold on;
title('Incomming Data from External Device');
xlabel('Data Number');
ylabel(' output (0-1)');
for i=1:numberOfDatas
% Get the data from the serial object
data(i) = handles.a.digitalRead(2);
% Plot the data
figure(1);
plot(i, data(i), 'm*');
drawnow;
end
Did i have to set the Baudrate, databits and stopbits to acquire data from arduino???

Everyone else that I have seen discussing the Arduino has been using the serial port to do the reading, not digital I/O. How exactly is your Arduino connected to the system you are running Matlab on?

I using digital I/O to control my motor through Matlab GUI, therefore i using digital I/O to acquire data from Arduino
