accelerometer return acceleration 0

Technical Java
#1

Today I tried to program the “FRC GYRO & ACCEL” we got on FIRST CHOICE. It is a On-Board accelerometer and gyro. the gyro work fine but the accelerometer always returns me 0 XYZ. The robot drove about 5m and noting changes. I used the ADXL362 class at the wpilib and tried all the functions to read the acceloration. Also tried to chage the sesor to another one. Help please.

Post your code

public class Robot extends IterativeRobot {
	RobotDrive myRobot;
	Joystick joystick;
	ADXL362  acc;
	CANTalon] drive = new CANTalon[4];
	
	@Override
	public void robotInit() 
	{
		for(int i = 1; i < 5; i++)drive* = new CANTalon(i);
		myRobot = new RobotDrive(drive[2],drive[0]);
		joystick = new Joystick(0);
		acc = new ADXL362(Accelerometer.Range.k4G);
	}

	@Override
	public void autonomousInit() {
		
	}

	@Override
	public void autonomousPeriodic() {

	}

	@Override
	public void teleopInit() {
	}

	@Override
	public void teleopPeriodic() {
		myRobot.arcadeDrive(joystick);
		if(acc.getX() != 0)System.out.println("X " + acc.getX());
		if(acc.getY() != 0)System.out.println("Y " + acc.getY());
		if(acc.getZ() != 0)System.out.println("Z " + acc.getZ());
	}

	@Override
	public void testPeriodic() {
		LiveWindow.run();
	}
}

i tried this code for testing but it doesnt print anything.*
