Notes on how to set up to use Eclipse IDE to develop for iRobot Roomba. You can follow the steps below or just download, extract, and import this:
Below is a shortcut method to set up Eclipse IDE Instead of using the pseudo-Java development tools provided by Processing The basic idea is to:
- Get Processing to work with Roomba. (i.e. follow procedures from Processing
- Copy the roombacomm libraries into a new Eclipse workspace
- Configure the classpaths
- Configure run paths through Eclipse
- Install Processing.
- This may require configuring the speed of the serial data communications link via an application like Zterm. for configuring Bluetooth
- If you are running on Mac OS 10.4, you will need to run the macosx_setup.command script as root in the Processing 0123 directory. NOTE: I could not get the macosx_setup.command script in the roombacomm-java_1.zip package to run.
- If you are running Mac OS 10.5, then you may also need to change some permissions on system folders.
Mac OS X 10.5 (from processing) error message:
check_group_uucp(): error testing lock file creation Error details:Permission denied check_lock_status: No permission to create lock file.
Create Eclipse Project
- Create a new Eclipse project using the "New Project Wizard"
- Copy /Applications/Processing 0123/libraries/roombacomm/library/* into the newly created Eclipse Project
- Add RXTXcomm.jar to buildpath
- Add roombacomm classes to buildpath
- roombacomm.jar to buildpath. OR
- rename "roombacomm.jar Folder" to "classes" and add as a src folder
Configure Execution within Eclipse
Any main class that will run Roomba code must add a VM argument to use the RXTX JNI libraries correctly.
The process of running is easy as 1,2,3,...,4, and 5!
- Eclipse Menu->Run->Open Run Dialog...
- create 'New' launch configuration
- Select a Java class that contains your main() method
- Add command line arguments and add the RxTx lib to your -Djava.library.path
- Save and Run!
Tested with a Macbook C2D, Bluetooth, Mac OS 10.4, Sun Java 1.5. If you have gotten your computer to connect to a Roomba and used the Processing dev environment, then there is no reason why you would not be able to get Eclipse IDE to work too.
