Serial 5 - Basic Processing from Jeff Feddersen on Vimeo.

PROCESSING CODE STEP 1.

FIRST - check console and its output from the Serial.list function -see code excerpt from processing sketch

below,you will then need to update the Serial port in your Processing code;

PROCESSING CODE (check serial port)

//processing EtchaSketch

// Etch-a-Sketch

// based on a sketch by Trevor Shannon

import processing.serial.*;

Serial myPort;

int lastX = -1;

int lastY = -1;

int x;

int y;

String nextXY;

void setup() {

size(512, 512);

background(255);

println(Serial.list());

myPort = new Serial(this, Serial.list()[3], 9600);

myPort.bufferUntil('\n');

}

void draw() {

String[] parts = splitTokens(nextXY);

if (parts.length >= 2) {

x = int(parts[0])/2;

y = int(parts[1])/2;

if (lastX >= 0 && lastY >= 0) {

line(x, y, lastX, lastY);

}

lastX = x;

lastY = y;

}

void mouseClicked() {

background(255);

}

void serialEvent(Serial p) {

nextXY = p.readString();

}

PC :

myPort = new Serial(this, Serial.list()[1], 9600);

MAC

ie you might be using a different port .ie - then you will need to update the number

PC :

myPort = new Serial(this, Serial.list()[1], 9600);

MAC:

myPort = new Serial(this, Serial.list()[3], 9600);

FIRST TEST IN PROCESSING with simple serial read
