Hi, I am trying to connect MATLAB to an Arduino Duemilanove using the MATLAB IO Support Package. It did work in the past (couple of weeks ago) using this board but now for some reason it does not want to connect to the board. When I use the "a=arduino('COM4')" it appears with the error:
??? Error using ==> arduino>arduino.arduino at 102
Connection unsuccessful, please make sure that the Arduino is powered on, running either srv.pde,
adiosrv.pde or mororsrv.pde, and that the board is connected to the indicated serial port. You might also
try to unplug and re-plug the USB cable before attempting a reconnection.
The argument at line 102 of the arduino.m file is as follows:
if isempty(chk)
delete(a);
error('*Connection unsuccessful, please make sure that the Arduino is powered on, running either srv.pde, adiosrv.pde or mororsrv.pde, and that the board is connected to the indicated serial port. You might also try to unplug and re-plug the USB cable before attempting a reconnection.*');
end
I have uploaded adiosvr.pde to the target board and closed down the Arduino IDE (as recommended by the readme.txt file). I have hunted on the web high and low through forums and so on but cannot find a viable solution to my problem. I am fairly new to MATLAB and the IDE language but I am an engineering student working on my dissertation and this is kind of imperative to the whole success of it. It's so frustrating that it was working and now it isn't. I haven't changed or removed anything.
ANY help would be greatly, greatly appreciated.
Regards,
Euan Millar
