About this project
Using this tool you can communicate with Arduino (compatible devices) using a special Java class directly within a thread. Serialduino support following connection types:
- COM ports
- TCP/IP
- Bluetooth RFCOMM
Download available on Github repository
How does it work?
Connection is based on a serial monitor class (ArduinoSerialMonitor.java). This class call some LinkDevice methods to communicate with Arduino. LinkDevice is an interface implemented from devices class, like ComLinkDevice, BluetoothLinkDevice and TcpLinkDevice.
Demo
To connect to Arduino using COM (or USB) port, you must pass ComLinkDevice object to ArduinoSerialMonitor constructor:
if (ComLinkDevice.isPortAvailable()){
// COM Port for Linux
//ComLinkDevice port=new ComLinkDevice(ComLinkDevice.getPortByName("ttyUSB0"), ComLinkDevice.BAUDRATE_9600);
// COM Port for Windows/Dos
//ComLinkDevice port=new ComLinkDevice(ComLinkDevice.getPortByName("COM1"), ComLinkDevice.BAUDRATE_9600);
// First COM serial port
ComLinkDevice port=new ComLinkDevice(ComLinkDevice.getPorts()[0], ComLinkDevice.BAUDRATE_9600);
ArduinoSerialMonitor arduinoSerial=new ArduinoSerialMonitor(port);
/* ........ */
}
you can find port automatically using getPorts() (it returns an array ports), or calling getPortByName(), passing port’s name (name can changes on different operating systems).
Next step is open connection and communicate with Arduino, using open(), send() and receiveString() method:
//open and wait for arduino reboot
arduinoSerial.open();
//if device ready, send "hello" string to Arduino
arduinoSerial.send("hello");
//Receive echo response: you should see "hello" on java console
System.out.print(arduinoSerial.receiveString());
you can close connection with close() method:
//Close connection arduinoSerial.close();
See src/main/java/io/github/emanuelepaiano/serialduino/examples for Bluetooth and TCP examples.
Dependencies:
SerialDuino require jSSC, for com support driver
Install
Import a compiled release into your Eclipse project. You need include jssc.jar and jssc-2.7.0-javadoc.jar for serial support. For Maven projects, you can add dependency into POM.XML file as described into README.md.
