OUTOFMEMORYERROR- arduino processing DINO

Hi to all,

I am a newbie, in fact I've started to use/learn Processing just yesterday. I my trying to build a hot-tub DINO- so an anrduino mega  is sending serial data to my pc then processing is used for displaying gauages an so on. This is what is all about.

Here is the problem, I'm stuck with this OUTOFMEMORYERROR after some minutes.Tried to increase memory as suggested by processing. It took some more time to crash but it did it again. Data input seems to be high to handle.

Is there something I can do like flushing the old data while using the incoming so to keep it to a minimum?

Any help appreciated. I thinking of dumping all and use another language but processing seems to the one with simple graphical contents I need.

THANKS

below is the arduino code:

#include <OneWire.h>

#include <DallasTemperature.h>

#define ONE_WIRE_BUS 3// Data wire is plugged into pin 3 on the Arduino

// Setup a oneWire instance to communicate with any OneWire devices

OneWire oneWire(ONE_WIRE_BUS);

// Pass our oneWire reference to Dallas Temperature.

DallasTemperature sensors(&oneWire);

// Assign the addresses of your 1-Wire temp sensors.

DeviceAddress vThermometer1 = { 0x28, 0xB0, 0x41, 0xEA, 0x03, 0x00, 0x00, 0x8B };

DeviceAddress vThermometer2 = {

0x28, 0x2B, 0x17, 0xEA, 0x03, 0x00, 0x00, 0xCB };

void setup(void)

{

// start serial port

Serial.begin(9600);

// Start up the library

sensors.begin();

// set the resolution to 10 bit

sensors.setResolution(vThermometer1, 10);

sensors.setResolution(vThermometer2, 10);

}

void loop(void)

{

sensors.requestTemperatures();

float collector = printTemperature(vThermometer1);

float tank = printTemperature(vThermometer2);



Serial.print("G0");

Serial.print(tank);

Serial.println("\n");



Serial.print("G1");

Serial.print(collector);

Serial.println("\n");

delay(10);

}

float printTemperature(DeviceAddress deviceAddress)

{

float tempC = sensors.getTempC(deviceAddress);

if (tempC == -127.00) {

//Serial.print("Error getting temperature");

}

else {

}

return tempC;

}

Below is processing code:

import processing.serial.*;

Serial myPort; // Create object from Serial class

PFont mono;

int gaugeangle=180;//gauge display angle

int gaugepositionx=250;//gauge position in form (x)

int gaugepositiony=250;//gauge position in form (y)

int gaugescalerange=180;//in degrees steps of 30 max 180

int gaugestartvalue=0;

int gaugeendvalue=50;

int gaugescale=50;

int gaugescalecolour=0;

int gaugepointercolourR=204;

int gaugepointercolourG=102;

int gaugepointercolourB=0;

float GaugeVariabileG0;

float GaugeVariabileG1;

void setup()

{

size(800, 800);

smooth();

String portName = "COM4";

myPort = new Serial(this, portName, 9600);

myPort.bufferUntil('\n');



}

void serialEvent(Serial myPort)

{

// read String from the serial port:

String inString = myPort.readString();

String xxx = inString.substring(0, 2); // returns type

if (xxx.equals("G0") == true )

{

GaugeVariabileG0=float(inString.substring(2));

}

if (xxx.equals("G1") == true )

{

GaugeVariabileG1=float(inString.substring(2));

}

}

void draw()

{

background(255);

pushMatrix();

translate( gaugepositionx, gaugepositiony);//gauge position

drawGauge( map( GaugeVariabileG0, gaugestartvalue, gaugeendvalue, 0, 1 )); //map GaugeVariabileG0

mono=loadFont("Digital-7Mono-48.vlw");

textFont(mono);

textAlign(CENTER);

text(nf(GaugeVariabileG0, 2, 2), -60, 48);

mono=loadFont("Tahoma-12.vlw");

textFont(mono);

textAlign(CENTER);

text("Tank Temperature", 0, 60);

popMatrix();

pushMatrix();

translate( gaugepositionx+250, gaugepositiony);//gauge position

drawGauge( map( GaugeVariabileG1, gaugestartvalue, gaugeendvalue, 0, 1 )); //map GaugeVariabileG0

mono=loadFont("Digital-7Mono-48.vlw");

textFont(mono);

textAlign(CENTER);

text(nf(GaugeVariabileG1, 2, 2), -60, 48);

mono=loadFont("Tahoma-12.vlw");

textFont(mono);

textAlign(CENTER);

text("Heat Exchanger Temperature Out", 0, 60);

popMatrix();

}

void drawGauge(float val)

{

stroke(gaugescalecolour);//scale colour

//draws scale

for ( int i=0; i<gaugescale+1; i++)

{//scale nos

float a = radians(gaugeangle + i * gaugescalerange / gaugescale);

float r1 = 110;//scale length

float r2 = 100;//scale lenght small div

r2 = i % 5 == 0 ? 85 : r2;

r2 = i % 10 == 0 ? 80 : r2;

line( r1*cos(a), r1*sin(a), r2*cos(a), r2*sin(a));//draws scale

}

//

//draws double circle around the gauge

//noFill();

//ellipse(0, 0, 270, 270);

// ellipse(0, 0, 290, 290);

//

stroke(gaugepointercolourR, gaugepointercolourG, gaugepointercolourB);//pointer border colour

fill(gaugepointercolourR, gaugepointercolourG, gaugepointercolourB);//pointer fill colour

float b = radians( gaugeangle + val * gaugescalerange );

ellipse(0, 0, 10, 10);//pointer dot itself

line( -10*cos(b), -10*sin(b), 100 * cos(b), 100 * sin(b));//pointer
