Once you’ve modified it, hit the “W” button and try to “Build Robot Code” you should get a successful build.įor this example, assume we have a joystick connected to drivers’ station and a motor controller connect to the roboRIO.The SmartDashboard is an alternate dashboard application written in Java. Your bare-minimum robot program is below. To keep this tutorial really simple, we’re going to delete everything except robotInit() and teleopPeriodic(). There are also methods for testInit(), testPeriodic(), disabledInit(), and disabledPeriodic().When the robot transitions into teleoperated mode, it will call teleopoInit() once and then call teleopPeriodic() repeatedly.When the robot transitions into autonomous mode, it will call autonomousInit() once and then call autonomousPeriodic() repeatedly.The standard for FRC robots is to attempt 50 calls a second. Then, no matter what mode it is in, it will call robotPeriodic() repeatedly. When the robot starts executing the program, it will initialize all class variables, and will then call robotInit().The robot will execute Robot.java as follows: This is the program executed by your robot. Step 2: Program to control one motorįrom the File Explorer, open up the “Robot.java” file.

All code will be compiled locally, and you should see the message “BUILD SUCCESSFUL”. Click on the “W” button and select “Build Robot Code”. You could deploy it to your robot, although it doesn’t do anything yet. This project is a complete robot program. Also, take a look at the “adle” file which controls how the project is compiled and deployed. In particular note that all the Java source code is under the “src” directory.

Once generated, VS Code will open the File Explorer sidebar, so you can see all the new files created. Generate the project and open it in the current window. Fill in a parent folder, project name, and your team number. The third button picks a specific Template or Example.įor this example, we’ll specify a Java template for “Iterative Robot”.The second button lets you choose either Java or C++ programs.Examples can also be the basis for your work, but they are especially useful to demonstrate different robot functions. Examples are projects for specific purposes. Templates are bare-minimum projects that can be the basis for your robot program. The first button lets you choose either Template or Example.There are three buttons just under the welcome message. This will pop open the WPILib Project Creator window. This is a button that will open up the Command Palette to show all the WPILib commands.Ĭlick on the “W” button, and select “Create a new Project”. If the WPILib extension is properly loaded, then every window’s title bar will have a red hexagon around the letter “W”. For this example, let’s assume we have the roboRIO set up on a test board, with a joystick, one motor and one motor controller. You can start coding before the robot exists, but if you have a physical robot available, so much the better. The WPILib extension contains a wizard to get you going quickly. Now that you’ve got Visual Studio Code installed and configured for WPILib, you can start creating robot programs.
