joy_tester

This is a very simple GUI program for testing joysticks in ROS. More specifically, it displays the messages of a sensor_msgs/Joy topic in a more user-friendly format.

Usage

ros2 run joy_tester test_joy

By default it subscribes to the /joy topic, but this can be remapped as with any other ROS node (e.g. with --ros-args -r joy:=other_joy).

Particularly helpful (compared to a topic echo) is that it displays the axis/button numbers which saves time and errors in counting them manually.

To Do

• Clean up the code, particularly GUI element placement (was a very rough first go)
• Add functionality for sending sensor_msgs/JoyFeedback (e.g. LED, rumble) back to controllers
• Some way to assist in calibration?
