Please help me, help me.
I have an Diecimila Board- usb. I am using one pushbutton and I want to see the graphic in processing. I went to this site: http://webzone.k3.mah.se/projects/arduino-workshop/projects/arduino_meets_processing/instructions/pushbutton.html
and everything is working fine on my arduino board.
In processing, I changed the portname to
String portname = "/dev/tty.usbserial-A4001mmw";
which is what i am using in arduino...
but there is this error : gnu.io.PortInUseException: Unknown Application
354) What is it? please help! ::
