Viewing Debug Graph

The Debug Graph shows the timing of the driver station control-loops, UI loops, and ping, as shown below. When the Driver Station and Robot Controller are operating as expected, the graph should show generally low and consistent values, potentially with occasional spikes.

Debug graph on the graphs tab

  1. Control-loop Runtime (Red) - displays the time each control loop takes in microseconds.

  2. UI loop runtime (Purple) - displays the time each UI loop takes in microseconds.

  3. Control-loop period (Orange) - displays the time between the start of each consecutive control-loop.

  4. UI loop period (Yellow) - displays the time between the start of each consecutive UI loop.

  5. Ping (Green) - displays the communication time between the Driver Station and Robot Controller.
