Examples | // Example by Tom Igoe import processing.serial.*; Serial myPort; // The serial port void setup() { // List all the available serial ports: printArray(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) { String inBuffer = myPort.readString(); if (inBuffer != null) { println(inBuffer); } } } | ||
Description | Returns all the data from the buffer as a String or null if there is nothing available. This method assumes the incoming characters are ASCII. If you want to transfer Unicode data, first convert the String to a byte stream in the representation of your choice (i.e. UTF8 or two-byte Unicode data), and send it as a byte array. | ||
