Class | Serial
Name | ### readString()
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.
Syntax |
    serial.readString()
Parameters |
serial | Serial: any variable of type Serial
Returns | String
