I’ve been trying to deploy code to the roborio for a few days now. It’s not connecting to the driver station either. It finds it in eclipse but it shows this

does this mean it was successful? I’m so confused. This is my first time using eclipse. And if anyone knows as to the roborio’s:confused not wanting to show up on the driver station, it’d be a great help.
Never mind. I still don’t understand why it won’t connect. All the firmware has been uploaded and the image updated. The code has been deployed and yet nothing.
It is the new driverstation, I have entered the team number into the driverstation, and I’m connected via ethernet cable. I’ve also tried with the type a to type b usb cable.
What he’s saying is that the roboRIO uses something called 0-indexed IO This means that the joystick (and all other IO identifiers) numbers go 0, 1, 2, 3. For the first, second, third and fourth ports respecivly
Your code:
controller = new Joystick(1);
sets up joystick in port 1, which is actually the SECOND port.
To solve this you can either
a) change the code to
controller = new Joystick(0);
b) change the driverstation so that the joystick goes into the SECOND port.
I recomend the first.
Onto your main problem.
When connected via ethernet, could you post the output of “ipconfig”
Are you getting No Robot Code, Comunications, or is it just not doing anything when you enable?
Now I’m getting communications. It just says there’s no robot code.

No, that’s fine. What is likely happening is that you’re initializing your speed controllers AFTER you initialize drive. They are null when passed to new RobotDrive(), which should throw a null pointer exception and crash. Try initializing the controllers before the drive.
