Deploying Problems with Gyros and Victors

Hello CD,

Using Commandbased robot templating system, our programming department has successfully created tankdrive code. We are trying to implement the gyroscope for drivestraight methods, but we keep getting deploying errors, especially:

[cRIO] edu.wpi.first.wpilibj.util.AllocationException: PWM channel 1 on module 1 is already allocated

Would it be possible for any team to post working java code with a gyro enabled, so we can see how you initialize the gyros, as well as your speed controllers.

Thank you so much. :]

This error means that you have created two sensors on the same channel in your code. Look through your code to check if two of your ports are the same or that two identical objects are created in different places.

I have posted a new project just with the gyro initialized. Here is the Github link and console error output.

Can someone please help us? We cannot figure out the problem. Thank you so much CD. :]

your problem is that your creating a new gyro for every instance of the command. create the gyro in robotmap or OI and reference it instead of creating a new one

You’re creating two chassis objects, once in CommandBase and once in team4gyro. Because of that, two gyro objects are created.
