ffjoystick — Provide joystick via blackboard or print movements
ffjoystick [-r host[:port]] [-d dev] [-l]
This tool is used to provide a joystick connected to the local machine to a Fawkes instance via the blackboard, or to print debug output about joystick data in the blackboard.
Generally, the joystick plugin should be preferred, because it operates faster within Fawkes. This is especially useful for joysticks communicating wirelessly with a USB dongle. For cabled joysticks however, this may not be feasible. In such situations, the joystick can be connected to a laptop or desktop, and the data is transmitted via a remote blackboard connection to the robot.
In the second mode, the tool prints out changes to the joystick blackboard interface. This can be used to verify and debug joystick communication, and to ensure that data is written to the correct blackboard.
Both modes are mutually exclusive. If -l is given on the command line, the second mode will be used, regardless of other parameters.
