Using Java RxTx library for Serial Communication With Arduino - Part 1.
![]() So this will be a good start if you are going to use RxTx library with Arduino. First you have to download the RxTx library from one of these locations. You can download x86 or x64 version according to your Operating System. Extract the downloaded file and add it to the project using Right Click the Project - Build Path - Configure Build Path - Libraries - Add External JARs - OK. Now Copy the two dll files (rxtxParallel.dll, rxtxSerial.dll) from the extracted library and paste it to the project folder. Now Run the program. My Arduino was connected to COM7 and heres the output. Take a look at this library alternative to RXTX Reply Delete Replies Kinath Rupasinghe March 29, 2015 at 11:25 PM You are most welcome:-). This is great. It would be helpful for others too.Thanks for sharing.

Java Serial Port Example How To Install AndMy library has (hopefully) great documentation and tells you exactly how to install and use it. After downloading both JARs in the library and including them in your classpath, just include the following statement before your class definition: import arduino.; Now, all youll have to do is know the serial port with which you want to communicate, and the baud rate at which you wish to communicate, and youre good to go with the following example code. String portName; Your port name here int BAUDRATE 9600; Baud rate for communication Arduino anySerialDevice new Arduino(portName, BAUDRATE); Even though the class is called Arduino, you can use this to connect to ANY serial device anySerialDevice.openConnection(); anySerialDevice.serialWrite(1); serialWrite is an overridden method, allowing both characters and strings. Java Serial Port Example Mac OSX AndI have tested the library on both Windows and Mac OSX and works reliably. PS: While the class is called Arduino, to simplify reading the code for novice arduino developers, as I have mentioned before, the use of my library can be extended to any serial device.
