Examples |
// Example by Tom Igoe
import processing.serial.*;
Serial myPort; // The serial port:
PFont myFont; // The display font:
String inString; // Input string from serial port:
int lf = 10; // ASCII linefeed
void setup() {
size(400,200);
// Make your own font. It's fun!
myFont = loadFont("ArialMS-18.vlw");
textFont(myFont, 18);
// List all the available serial ports:
println(Serial.list());
// I know that the first port in the serial list on my mac
// is always my Keyspan adaptor, so I open Serial.list()[0].
// Open whatever port is the one you're using.
myPort = new Serial(this, Serial.list()[0], 9600);
myPort.bufferUntil(lf);

Description |
Called when data is available. Use the read() method to capture this data. The serialEvent() can be set with buffer() to only trigger after a certain number of data elements are read and can be set with bufferUntil() to only trigger after a specific character is read. The which parameter contains the name of the port where new data is available, but is only useful when there is more than one serial connection open and it's necessary to distinguish between the two. |
