gnu.io.PortInUseException Mar 25th, 2010, 11:56am   I am trying to run the SimpleWrite example from Examples->Libraries->Serial I cannot because I always get. Code: Cannot run Java in 32 bit mode. Continuing in 64 bit mode. Stable Library ========================================= Native lib Version = RXTX-2.1-7 Java lib Version   = RXTX-2.1-7 porto encontrado /dev/tty.usbserial-A8004IM1 gnu.io.PortInUseException: Unknown Application I tried to follow http://processing.org/reference/libraries/serial/ but did not understand what was supposed to do for Mac. I read http://processing.org/discourse/yabb2/num_1170029680.html#7 but what I tried didn't work. I have searched high and low but alas, no answer was found

Use this line of code to view available ports: Serial.list(); Which one were you trying to use? myPort = new Serial(this, "COM1", 9600); Where "COM1" is the name of the port.

But I dunno   Thank you for the reply anyway

NoahBuddy Ex Member	Re: gnu.io.PortInUseException Reply #3 - Apr 1st, 2010, 12:24am   Is Arduino reading from that port when you run your sketch? By chance does your sketch call "new Serial(...)" inside the draw() method?

I have been trying to fix this ever since so now I think the problem is on the command Code: myPort = new Serial(this, portName, 9600); on setup I re-checked again and the serial monitor of Arduino IDE works just fine.
