Processing communications to Arduino

in Integration and Hardware • 11 months ago

Hi Guys

I have a problem with processing communicating with arduino. I'm sure the problem is with processing
as the board is working fine.
I'm running windows7 64-bit and read somewhere that the latest beta processing software has problems
with serial when it comes to 64-bit windows, so I reverted back to V1.5.1.
Now I getting the following errors.
Originally the RXTX library versions were different but i got that mended but I'm still getting java connection
errors.
I've exhausted all solutions online.
Any help would be appreciated.

Display 0 does not exist, using the default display instead.

Are you using Arduino Processing or the Processing 2.0?

I'm using processing 1.5.1 with the arduino library installed.
I'm also running arduino 1.0.1 IDE.

Sorry I'm a relative noob at this, hope this answers your question

Thanks for the response.
I've moved to a different machine. Windows 32-bit.
I'm using the same IDE's as before for both arduino and processing.

On this machine I've uploaded the StandardFirmata example to the arduino using arduino IDE.

I then tried to run the below simple sketch in processing and got "RXTX library mismatch".
Once I fixed that I restarted processing and ran the below sketch again. Now it shows the
RXTX libraries matching but no led blinking on the board. I have no errors.
I'm running out of ideas!

import processing.serial.*;
import cc.arduino.*;

Arduino arduino;
int ledPin = 13;

void setup()
{
//println(Arduino.list());
arduino = new Arduino(this, Arduino.list()[0], 57600);
arduino.pinMode(ledPin, Arduino.OUTPUT);
}

void draw()
{
arduino.digitalWrite(ledPin, Arduino.HIGH);
delay(1000);
arduino.digitalWrite(ledPin, Arduino.LOW);
delay(1000);
}
