  • No IO though driver station

    We seem to be having trouble with the drive system.
    We can't get the joystick, motors, or the LCD output to work.
    We get no errors from building, deploying, running, or on the cRIO console.
    We also get a voltage reading of about .7-.8 volts while everything is running
    Using c++

    We have tried:
    • Double & triple checked the .out file to send to the cRIO
    • Flashing the cRIO
    • Swaping the cRIO
    • Swaping the digital sidecar
    • trying the most basic code possible
    • new battery
    • two different computers
    • different controllers
    • wireless and wired connections to the cRIO


    we have our subnet mask set to 255.255.255.0 b/c our router does not allow us to change it to 255.0.0.0.

    Router used only when using wireless
    • Router IP 10.20.2.1
    • Bridge / Robot: 10.20.2.2
    • Computer IP: 10.20.2.6


    None of can figure it out..

    The Bridge and the robot should not use the same IP address. The bridge should be .1, and the robot .2. When the router was part of the standard setup a few years ago, it was .4.

    On the driver station software, what are the LEDs for communication and robot code? On the diagnostics tab, what LEDs are lit?

      On the driver station the
      Communications light is green
      Robot Code is green
      On the diagnostics tab all the com lights are green but the FMS one

        Hi, welcome to the FIRST forums.

        I would recommend breaking the issue down and trying to address one thing at a time.

        The battery voltage should be the easiest to address so I would recommend starting there. To properly report battery voltage the cRIO must have an NI 9201 Analog Module plugged into slot 1. An analog breakout board, powered by 12V from the Power Distribution board must be plugged into the analog module. A jumper must be placed on the outside two pins of the breakout board.

        See Rule R64 from last year's manual for a picture of the jumper configuration.


        For the joysticks, start by making sure that the joysticks show up on the Driver Station Setup tab and that each turns blue when you push a button. What indication do you have that the joysticks are not working? If your testing of the joysticks is directly tied to the motors I would break the problem down and attempt to run the motors with a constant value.

        When you enable the robot do the lights on the motor controllers go solid?

          Whops...

          We plugged the digital sidecar into a board on the cRIO; not on the power distribution thing.

            Well, the Digital Sidecar plugs into both a cRIO module and the Power Distribution board.

            For information on wiring the robot see the Getting Started with the Control System, the Power Distribution Diagrams on this page, and the Data Connectivity Diagrams on this page.

              Yes, but we had it only plugged into the cRIO
