Post Snow Leopard serial not working
Sep 1^st, 2009, 4:07pm

I have an arduino running firmata which has stopped responding after the snow leopord update.
I think I've narrowed the problem down to the serial library.

when running this sample code

// Example by Tom Igoe

import processing.serial.*;

// The serial port:
Serial myPort;

// List all the available serial ports:
println(Serial.list());

/* I know that the first port in the serial list on my mac
is always my Keyspan adaptor, so I open Serial.list()[0].
Open whatever port is the one you're using.
*/
myPort = new Serial(this, Serial.list()[0], 9600);

// Send a capital A out the serial port:
myPort.write(65);

-----
I get the error

java.lang.UnsatisfiedLinkError: /Applications/Processing.app/Contents/Resources/Java/libraries/serial/library/li
brxtxSerial.jnilib: no suitable image found. Did find: /Applications/Processing.app/Contents/Resources/Java/libraries/serial/library/li
brxtxSerial.jnilib: no matching architecture in universal wrapper thrown while loading gnu.io.RXTXCommDriver
java.lang.UnsatisfiedLinkError:

any ideas?

Snow Leopard finally gave JAVA SE 6.0 to Mac users
Arduino however is NOT compatible with the JAVA SE 6.0, so you have to go back to JAVA SE 5.0
Hopefully you made a backup of your old system (chompingatbits.com/files/BACK_UP_JAVA_5_ON_LEOPARD.php)

When you restored JAVA SE 5.0, go to the Utilities folder in Applications.
Open the application Java Preferences
Move java 1.5 to the top (in the bottom box)
Restart processing.

Happy coding!

(Hopefully processing updates soon to work with JAVA SE 6.0)

If you run Processing in 32 bit mode (as I understand it, there's a checkbox in the Get Info dialog), you may be able to get serial working.

I'm half way there. The checkbox is actually called "open using rosetta" and it seemed to clear up the serial issues (thanks!). Next problem is firmata communication between the latest versions of Arduino and Processing.
The hello world code runs, but no blinking light. I uploaded the latest arduino library for processing and installed it in the libraries folder, and I installed the latest driver from here (opps need to post more before I can put up links - ftdichip.com/)

import processing.serial.*;
import cc.arduino.*;
Arduino arduino;
int servoPin = 10; // Control pin for servo motor

void setup(){
size (180, 50);
println(Arduino.list());
arduino = new Arduino(this, Arduino.list()[0]);
arduino.pinMode(servoPin, Arduino.OUTPUT);
}
void draw(){
arduino.analogWrite(servoPin, mouseX);
}

interestingly the RX light blinks but not the led in pin 13.
this was the case on a Duemilanove and a Dieimila.
yes I tried different LED's Wink

I'd love any help you can give me

I installed the latest Processing. The serial port problem disappeared however I got a new error message:

It must be the MIDI/audio driver, will try to update it.

Solved it! First, I had Processing 1.01. Installed the latest, 1.0.9, got different errors... Then realized I only have java1.6 (go to utilities->Java Preferences). Following this http://wiki.oneswarm.org/index.php/OS_X_10.6_Snow_Leopard procedure which restored Java1.5 (requires password,when you type it cannot be seen...jut type it and hit return), went back to Java Preferences and set things to java1.5 32 bit. Problem solved.
