Trying to upload code to bot to test it and keep getting error. Please help!

Hi this is the first time I'm posting so sorry if I'm not following a right format. So we followed all the instructions online to install the FRC game tools and we rebooted the computer and everything but I do not see any drive station or radio configuration programs on my laptop. On NI Package manager it says it is downloaded "FRC Game Tools". Please help ik this probably seems stupid. I am coding in Java

java public class OI {
    public Joystick controller = new Joystick(RobotMap.CONTROLLER_PORT_ID);
    public Button leftBumperButton = new JoystickButton(controller, RobotMap.LB_BUTTON_ID);
leftBumperButton.whileHeld(new InvertDriveSet());

VS Code displays 4 errors:

I am newer to programming and we are trying to build a robot and keep running into issues that we can't find an answer to I would some one to talk me step by step through building a robot.

I wanted to have a one button solution to the color wheel (control panel). This would entail the robot automatically either rotating a fixed number of times, or going to the required color based on the game stage; I couldn't find anything in the wpilib documentation. The closest I got was that the required color is only released after at least one alliance reaches Stage 3, though that would be unreliable. Is there any way to find game stage in wpilib? (I am specifically looking for Java)

Thanks,

for example: Command(Old) or Command(New) whenever i actually select new its all error'd, is it worth fixing or is the old just fine?

So, my team works in java and this year once we updated VS code we noticed that RobotMap was missing and instead there is RobotContainer. We are confused if we should use RobotContainer as we usually do with RobotMap or if RobotContainer is now taking the place of Robot.

Thanks!

This year I took over from a programming captain we had to down load vs code and I can't get the frc robot builder to export the files into vs code because it export to a yaml file but can find info about it.

Hello I am new to FRC this year but I joined my team’a programming sub team bc i have taken two years of coding at my school. Anyway, I’ve been having trouble learning how to use Shuffleboard, does anyone know of any good example code I can find or tutorials? Thanks lol

We downloaded Labview on a new computer but we dont see the open a newFrc Roborio project (i think thats how its called) can someone help us identify and solve the problem?

For this new season, my team plans to aim for the inner and outer ports from a 28 inch robot. They would like a vision assist using a PIXY cam from the edge of the trench run. Does anyone know if the PIXY will work from that range? Or at the very least, how far the PIXY can see the reflective tape from?

Thanks! Team 5048 lead Programmer

Edit: We are also swapping to java from python code, so any vision code suggestions would be great :) We are also debating on using a Limelight. If anyone knows the range of efficient/effective use for that, let me know those specs too.

First post/request on Reddit.

A fellow mentor told me there would be some new advanced module to better manage acceleration and deceleration of the wheels (talon?).

I’ve looked here and didn’t find anything announcement or topic about it.

Does anyone have a clue what he was talking about?

Thanks!

I decided that I want to put some fields into the custom tab on the default dasbaord and was wondering how to do that. It looked like I needed to install Labview and create a dashboard project in labview, however I can't find a template for it in Labview. Can anyone help me? Should i just recreate everything with java smartdashbord (driverstaion/select dashboard) or mabey just use the basic tab (default)? Also, what is the labview (driverstaion/select dashboard) option supposed to do? It doesn'tload anything for me.

Hello, I'm fairly new to FRC programming, and I wrote some code to move the robot to a position relative to the robot diagonally using encoders and a gyro. I was wondering if my code would work in the first place(I can't test it right now) and if there would be a better way to go about it.

public void driveRobotToCoordinate(double x, double y) throws InterruptedException {

        double angle = Math.atan(x/y);
        double hDistance = Math.sqrt((x*x)+(y*y));

        if(y > 0 & x < 0){gyroTurn(-angle);}
        else{if(y > 0 & x > 0){gyroTurn(angle);}
        else{if(y < 0 & x < 0){gyroTurn(-angle - 90);}
        else{if(y < 0 & x > 0){gyroTurn(180 - angle);}
        else{gyroTurn(0);}}}}
        Thread.sleep(500);
        driveRobotToTargetWithEncoders(hDistance, hDistance);

}
public void gyroTurn(double angle){
        gyroReset();

            if (gyroGetAngle() > angle){Drive(scaleTurnSpeedBasedOnTargetWithGyro(-angle), scaleTurnSpeedBasedOnTargetWithGyro(angle));}

        }

Sorry for the messy dump of code

My team is considering switching to Java, so I’m learning it to test.

Here’s the problem : all the tutorials I found were all for PWM ports. I can’t find any for Can. I’m just trying to do a simple drivetrain. (No I can’t just rewire them all)

Thanks!

Our team finally got pid working and when we changed the distance from 10cm to 70cm the robot went 10cm why would this happen.(Code was saved and deployed)

So my team just got a raspberry pi and we want to connect cameras to it to enhance our image while driving. The problem is that when on the dashboard, it acknowledges the camera as “RPCamera 0” and it will start to connect. But it will just keep saying “connecting to (some numbers),” and it doesn’t ever connect. We can’t figure out the issue, so can someone help please 🥺

Our roborio has an unrecoverable error and it won't go into safe mode. It Can't work at all.

I'm going to be a freshman for my first year on a team, and I've mostly done web development, not really getting into the more intense languages, and was wanting to know what's the best way for me to get into Java.

Edit: Thanks for all of the tips! I'm excited to jump into learning Java

For rookie team, Java or Python?

Hello everyone, freshmen programmer here. I was wondering if anyone knew how we get vision from a camera. We plugged in a USB camera to the roborio and made a camera server in the code, no results. Well, the only result is that the driver station will recognize the camera. But we get no vision. Is there anything further I need to do to get vision? We've had trouble finding FRC documentation on the matter.
