HelloBrick

This is a simple project for running code on Lego Mindstorms EV3, using leJOS. The project contains a class with helper methods, EV3Helper, which may make it easier to use the device. It also contains a main class and some examples which utilizes the helper methods for some simple movement.

Requirements

This project requires that you have Java Development Kit 7 installed on your system.

Getting Eclipse

There exists a plugin for leJOS to Eclipse, which makes development easy. For convenience we are distributing Eclipse bundled with the Lejos EV3 plugin.

• Eclipse for Windows 64-bit
• Eclipse for Windows 32-bit
• Eclipse for OS X 64-bit
• Eclipse for OS X 32-bit
• Eclipse for Linux 64-bit
• Eclipse for Linux 32-bit

After launching Eclipse, you may have to set EV3_HOME, if it is not set. You can do this by selecting Window -> Preferences -> leJOS EV3. Set EV3_HOME to the leJOS_EV3_0.9.0-beta directory inside the eclipse directory you unpacked.

Creating a project

To create a project select File -> New -> LeJOS EV3 Project. Uncheck Use default location and select the location you placed this project. Make sure the selected JRE environment is JavaSE-1.7. Finally, press Finish.

After creating a leJOS-project, if the leJOS-libraries can't be found, right click on your project and select leJOS EV3 -> Convert to leJOS EV3 project.

Other development methods

If you rather want to set up Eclipse with the leJOS-plugin yourself, you may follow the guide in README-ECLIPSE.md.

If you want to use IntelliJ, you may follow the guide in README-INTELLIJ.md.

If you want to build using Apache Ant instead of Eclipse, you may follow the guide in README-ANT.md.
