Gyro Error Message
 

For some reason our gyro code has stopped working, it worked fined for the last few weeks and now we cannot even initialize a simple Analog Gyro without getting an error message and getting no robot code to the robot.

The error is as follows:

ERROR Unhandled exception: java.lang.RuntimeException: Code: -1005. HAL: A pointer parameter to a method is NULL at [edu.wpi.first.wpilibj.hal.AnalogJNI.setAccumulator Deadband(Native Method), edu.wpi.first.wpilibj.AnalogInput.setAccumulatorDe adband(AnalogInput.java:279), edu.wpi.first.wpilibj.AnalogGyro.setDeadband(Analo gGyro.java:239), edu.wpi.first.wpilibj.AnalogGyro.initGyro(AnalogGy ro.java:56), edu.wpi.first.wpilibj.AnalogGyro.<init>(AnalogGyro .java:106), edu.wpi.first.wpilibj.AnalogGyro.<init>(AnalogGyro .java:90), org.usfirst.frc.team3314.robot.Robot.robotInit(Rob ot.java:82), edu.wpi.first.wpilibj.IterativeRobot.startCompetit ion(IterativeRobot.java:72), edu.wpi.first.wpilibj.RobotBase.main(RobotBase.jav a:241)]

The only thing we are doing with gyro now is creating it below Iterative Robot, and then initializing it in robotInit.

Any help or insight would be appreciated.

Thanks!

What port is the gyro on

Could you post this code

Re: Gyro Error Message
 

The gyro is on Analog port 3

Re: Gyro Error Message
 

Gyros can only be on ports 0 and 1 (those two are the ones the FPGA has accumulators hooked up to)

Re: Gyro Error Message
 

Can you try moving it to port 0 or 1?

I don't think you can connect an AnalogGyro to ports other than 0 or 1 on the roboRIO. See: http://wpilib.screenstepslive.com/s/...ving-direction, it indicates that the FPGA used for integrating the gyro data is only available on ports 0 and 1.

That was it, guess you learn something new even after a 3 years doing this. Thanks for the help everyone!
