Making Java and Arduino have a simple conversation isn’t too hard – after all, the is written in Java and uses the Java library – however there are a few tricks that can make the difference between hair loss and success. The has an article which almost has all you need to get things working, however I found a little extra Googling was required before I had success. The following steps should get the conversation between the technologies started if you’re running on a Mac, assuming you already have an Arduino loaded with some code that spits text out to serial (see the article for an example). Setup the RXTX library.
Create a folder for your Java project – this is where you’ll be dumping all your files. and unzip the RXTX library and place is in your project folder. Create a Java Project and Test Program. Open up Eclipse and create a new Java project ( File New Project.).
Open up your project properties ( Project Properties), select Java Build Path, and then Add Jars. Select the RXTXComm.jar and click OK. Create a new class (right click on your project’s src folder, then select New Class). Copy the sample code from the article. Create a new launch configuration (Run Run Configurations, then select the New launch configuration button). In the arguments tab add the following VM argument: – Djava.library.path=/path-to-lib/rxtx-2.1-7-bins-r2/MacOSX Changing the path as appropriate for your rxtx version and location. Select the Environment tab then click New and create the following environment variable: Name: DYLDLIBRARYPATH Value: /path-to-lib/rxtx-2.1-7-bins-r2/MacOSX Select OK and close the Run Configurations dialog.
Fix Problems with Native Libraries. If you try to run the configuration now it will most likely fail with an error along the lines of: /path-to-lib/librxtxSerial.jnilib: no matching architecture in universal wrapper This can easily be fixed by downloading a more complete and compatible version of the native side of the RXTX library from. Use this to replace the.jnilib file in /path-to-lib/rxtx-2.1-7-bins-r2/MacOSX. Big thanks to for this. Find Your Device and Port.
Back in Eclipse, find this line your sample program System.setProperty('gnu.io.rxtx.SerialPorts', '/ dev/ttyACM0'); and comment it out. The first thing the program does is try to find the port you will be communicating with.
The sample code has a list that probably doesn’t include the port you are looking for associated with your device. To remedy this add some printlns to log all of the found ports. In the port searching loop find this line: CommPortIdentifier currPortId = (CommPortIdentifier) portEnum.nextElement; and add this line after it: System.out.println('Found '+currPortId.getName);.
Connect your Arduino to your Mac’s usb port and run the program. You should see a list of ports something like this: Found /dev/tty.Bluetooth-Incoming-Port Found /dev/cu.Bluetooth-Incoming-Port Found /dev/tty.Bluetooth-Modem Found /dev/cu.Bluetooth-Modem Found /dev/tty.STARLIGHT-COM7 Found /dev/cu.STARLIGHT-COM7 Found /dev/tty.wchusbserial410 Found /dev/cu.wchusbserial410 In my case the device is /dev/tty.wchusbserial410. Find the PORTNAMES variable at the top of the class and add your device to it.
Run the program again and your Java program should be intently listening to all your Arduino has to say and spit it out to the console for you to see! Importing some cheap Arduino Nano knockoffs from China certainly saves some coin, but they may not work out of the box. Selecting Apple Logo About This Mac System Report and selecting Hardware USB, you may find a message along the lines of “Device has not been configured”. This is because the Nanos prevalent on eBay use a different chipset for the USB to serial communications. This requires download and installation of drivers (for Mac at least, and I believe for Windows too; apparently Linux works out of the box though). The chipset used for USB-to-serial is CH340/CH341, drivers for which can be downloaded. Unfortunately the drivers won’t work so easily on OS X Yosemite.
The following steps are required to get the Nanos working on OS X:. Download the driver from the Chinese website. Unzip the downloaded file and run the install package (ch34xInstall.pkg). To enable the driver open a Terminal window and enter the following command: sudo nvram boot-args='kext-dev-mode=1'. Restart your Mac.
Open the Arduino IDE, make sure your Nano is connected via the USB cable, and you should now find it in Tools Serial Port. You should now be ready to upload trouble free! Credit for the above procedure is due to the following:. The cheap Nanos can be found on ebay, e.g.
Very strange. Unfortunately I don't have enough time at the moment to debug but I have a hacky suggestion: try. If you go to Examples Libraries serial you should be able to modify one of the samples to use your port and see if the port can be opened to begin with. If it does, go one step further and try reading/writing to the port.
If this is all fine, you can use the Processing's serial library in your java project, or see it's implementation (e.g. C: Program Files (x86) processing-2.0.1 modes java libraries serial). HTH – Sep 18 '14 at 12:38.
Fork of the project to primarily provide a compiled native 64-bit package for Windows and Linux. RXTX is a Java native library providing serial and parallel communication for the Java Development Toolkit (JDK). RXTX is licensed under the GNU LGPL license as well as these binary distributions. RXTX is a great package, but it was lacking pre-built binaries for x64 (64-bit) versions of Windows. This project distributes binary builds of RXTX for Windows x64, x86, ia64 and Linux x86, x8664. These builds are compiled with the latest Microsoft Visual Studio tools. The latest CVS snapshots of RXTX were much better and more stable than the versions on the official rxtx.org website.
Therefore, builds for Linux are also included to be consistent with the Windows binaries. Sponsored by RXTX for Java is proudly sponsored.
We love the service and think you would too. Attribution and license While an attribution is not required, the following would be appreciated somewhere within your project or source code.
If you include any of the builds in your own personal or commercial application, please make sure to at least provide a note of thanks to Fizzed, Inc. In your release notes. The following statement below is an example: RXTX binary builds provided as a courtesy of Fizzed, Inc. (Please see for more information. Caveats. Builds are based on recent CVS snapshots.
Please see the ReleaseNotes.txt for information about which snapshot I based this distribution on. Removed UTSNAME warning from.c files to match kernel with the version you compiled against. Changed version in RXTXVersion.jar and in SerialImp.c to match this release so that the CVS snapshot was known. Win-x86, win-x64, ia64 Built using Microsoft Visual C 2008 - not MinGW. The x86 and x64 versions are native and do not rely on any other non-standard windows libraries. Just drop in the compiled.dlls that are specific to the version of Java you run.
If you installed the 64-bit version of the JDK, then install the x64 build. Tested the x86 and x64 versions with Windows 2008, 2003, and Vista SP1.

I add some detail to my question. I receive on my Xbee device a flow of GPS coordinates but I'm unable to read and stock these data on a buffer. My Xbee device is connected to my laptop on a usb serial port, that's why I want to create a program java to read and use my data flow sending by the serial port. I'm searching on internet some code example or tutorials, without enought advices for my understanding, or I just find some dead projects. I found that it's possible to use jssc library or javax.comm (but I can't download the javax.zip on sun).
Do you know an other better USB API? Could you help me to understand how I can manage to read and stock my Flow of GPS cordinate? Forget abut USB, it acts as transparent bridge. What you need is a way to read from the serial port. Javax.comm is not (officially) available any more.
I have been successfull dealing with the arduino serial port with the library. First make sure you see the serial port on your dev machine. This might require to install a driver. Then use a terminal program to connect to the serial port. Once this is working go on and get RXTX working. Just in case: You can have only one connection at a time. Make sure that only one of IDE, terminal programm and RXTX is connecting to the serial port at the same time.
