// Example by Tom Igoe
import processing.serial.*;
Serial myPort; // The serial port
void setup() {
// List all the available serial ports
println(Serial.list());
// Open the port you are using at the rate you want:
myPort = new Serial(this, Serial.list()[0], 9600);
}
void draw() {
while (myPort.available() > 0) {
int inByte = myPort.read();
println(inByte);
}
}
|
| Description | Returns a number between 0 and 255 for the next byte that's waiting in the buffer. Returns -1 if there is no byte, although this should be avoided by first cheacking available() to see if data is available. |
