RobotPy NetworkTables Project

This is a pure python implementation of the NetworkTables protocol, derived from the wpilib ntcore C++ implementation. In FRC, the NetworkTables protocol is used to pass non-Driver Station data to and from the robot across the network.

This implementation is intended to be compatible with python 2.7 and python 3.3+. All commits to the repository are automatically tested on all supported python versions using Travis-CI.

Note

NetworkTables is a protocol used for robot communication in the FIRST Robotics Competition, and can be used to talk to SmartDashboard/SFX. It does not have any security, and should never be used on untrusted networks.

Documentation

For usage, detailed installation information, and other notes, please see our documentation at http://pynetworktables.readthedocs.io

Installation

On the RoboRIO, you don't install this directly, but use the RobotPy installer to install it on your RoboRIO, or it is installed by pip as part of the pyfrc setup process.

On something like a coprocessor, driver station, or laptop, make sure pip is installed, connect to the internet, and install like so:

pip install pynetworktables

Implementation differences as of 2015

  • Implementation is pure python, no SIP compilation required!
  • API is now based on the Java implementation, methods are now camelCase, instead of CapsCase
  • NetworkTables objects are found in the networktables package, and not in the pynetworktables package

Support

The RobotPy project has a mailing list that you can send emails to for support: robotpy@googlegroups.com. Keep in mind that the maintainers of RobotPy projects are also members of FRC Teams and do this in their free time.
