First attempts

OS: Mac OS X Leopard. Got VCP drivers, can see serial device, can open it.

Get Semantic Error: No accessible field named "LOW" was found in type "Temporary_5629_9527".

when I try to use digitalWrite(ledPin, LOW); or digitalWrite(ledPin, HIGH);

So far, program is:

import processing.core.*;
import processing.serial.*;

Serial port; // Create object from Serial class
int ledPin = 4;

void setup() {
size(200, 200);
noStroke();
frameRate(10);
// Open the port that the board is connected to and use the same speed (9600 bps)
port = new Serial(this,Serial.list()[0], 9600);
}

void draw() {
background(255);
if (mouseOverRect() == true) { // If mouse is over square,
fill(204); // change color and
digitalWrite(ledPin, LOW);
} else { // If mouse is not over square,
fill(0); // change color and
digitalWrite(ledPin, HIGH);
}
rect(50, 50, 100, 100); // Draw a square
}

boolean mouseOverRect() { // Test if mouse is over square
return ((mouseX >= 50) && (mouseX <= 150) && (mouseY >= 50) && (mouseY <= 150));
}

OK, I see.. no, I have a Wiring board.

So.. I need http://dam.mellis.org/w4p/ to write I assume??

I tried http://dam.mellis.org/w4p/wiring_out.pde

and I get

/tmp/build38916.tmp/Temporary_4562_9426.java:36:1:36:6: Semantic Error: Type "Wiring" was not found.

Though I think it's pretty odd that http://wiring.org.co/learning/examples/led_blinks.html uses digitalWrite ..

Yes, I realized that I needed to download Wiring, not Processing. Got the little puppy working now.. thanks!
