Install and test java-simple-serial-connector with Arduino, on Ubuntu

As the new Arduino 1.5.6 BETA replaced RXTX library with JSSC (https://code.google.com/p/java-simple-serial-connector/), this video show how to install JSSC and setup on Netbeans, build a Hello World run on Ubuntu Linux, to send data to Arduino Esplora board. Actually the setup steps and example code follow https://code.google.com/p/java-simple-serial-connector/wiki/jSSC_Start_Working.


The last version of jSSC can be downloaded here: http://code.google.com/p/java-simple-serial-connector/downloads/list

In order to work on Ubuntu, modify the example code to change SerialPort to "/dev/ttyACM0".

package java_testjssc;

import jssc.SerialPort;
import jssc.SerialPortException;

public class Java_testjSSC {

    public static void main(String[] args) {
        SerialPort serialPort = new SerialPort("/dev/ttyACM0");
        try {
            System.out.println("Port opened: " + serialPort.openPort());
            System.out.println("Params setted: " + serialPort.setParams(9600, 8, 1, 0));
            System.out.println("\"Hello World!!!\" successfully writen to port: " + serialPort.writeBytes("Hello World!!!".getBytes()));
            System.out.println("Port closed: " + serialPort.closePort());
        }
        catch (SerialPortException ex){
            System.out.println(ex);
        }
    }
    
}

The Arduino side code, refer to the post "Serial communication between Arduino Esplora and PC".

Next: A simple Java application using java-simple-serial-connector library (jSSC) , with JavaFX user interface, send bytes to Arduino Esplora via USB.
