software overview crio imaging tool
Software OverviewcRIO Imaging Tool

Before use, the cRIO must be “imaged” by loading the VxWorks operating system, filesystem, FPGA code and the FIRST configuration files that determine whether LabVIEW or C++ will be used.

The cRIO Imaging Tool is used to “Image” and name the cRIO and set the cRIO IP address.

The tool is also used to select whether LabVIEW or C++ will be used for programming. This can be done at any time without re-imaging the cRIO.

software overview the dashboard
Software OverviewThe Dashboard
  • A LabVIEW vi that runs on a PC that is connected to the Driver Station.
  • Can display and analyze data from the robot.
  • Can display and analyze images from the robot’s camera
  • A default version is supplied, or a custom dashboard can be built by the user.

    • Are you interested in software primarily as a means to an end, for example, to create a champion robot?
    • Or are you interested in software for its own sake. Do you love programming and computers?
    • Are you primarily interested in software engineering??
    • Or are you primarily interested in another discipline that might involve testing, such as electrical or mechanical engineering?

software overview recommendations
Software OverviewRecommendations
  • Spend time at http://forums.usfirst.org/
  • Download the WindRiver Workbench Evaluation and learn how to use it.
  • Download LabVIEW from 2009 Control System Information and learn how to use it.
  • Plan to try out both LabVIEW and C++/WindRiver Workbench. The default code for both is easy to figure out if you Read the Directions.
  • Pay the $60 and get your kit early.
  • Call us if you need help.
software overview robot operating modes
Software Overview Robot Operating Modes
  • Disabled Mode: Before a match begins, robot outputs (motors) are not active. Robots can be programmed to initialize. Driver controls are active.
  • Autonomous Mode: During the first 15 seconds of a match, driver inputs (joysticks) are not active. Robots can be programmed to use outputs (motors) and sensor inputs (encoders, gyros) for autonomous operation.
  • Teleoperated Mode: During the remaining 120 seconds of a match, all inputs and outputs are active. Robots are programmed for driver control.
