Cabana

Cabana is a tool developed to view raw CAN data. One use for this is creating and editing CAN Dictionaries (DBC files), and the tool provides direct integration with commaai/opendbc (a collection of DBC files), allowing you to load the DBC files direct from source, and save to your fork. In addition, you can load routes from comma connect.

Examples

Running Cabana in Demo Mode

To run Cabana using a built-in demo route, use the following command:

cabana --demo

Loading a Specific Route

To load a specific route for replay, provide the route as an argument:

cabana "a2a0ccea32023010|2023-07-27--13-01-19"

Replace "0ccea32023010|2023-07-27--13-01-19" with your desired route identifier.

Running Cabana with multiple cameras

To run Cabana with multiple cameras, use the following command:

cabana "a2a0ccea32023010|2023-07-27--13-01-19" --dcam --ecam

Streaming CAN Messages from a comma Device

SSH into your device and start the bridge with the following command:

cd /data/openpilot/cereal/messaging/
./bridge &

Then Run Cabana with the device's IP address:

cabana --stream --zmq <ipaddress>

Replace <ipaddress> with your comma device's IP address.

While streaming from the device, Cabana will log the CAN messages to a local directory. By default, this directory is ~/cabana_live_stream/. You can change the log directory in Cabana by navigating to menu -> tools -> settings.

After disconnecting from the device, you can replay the logged CAN messages from the stream selector dialog -> browse local route.

Streaming CAN Messages from Panda

To read CAN messages from a connected Panda, use the following command:

cabana --panda

Using the Stream Selector Dialog

If you run Cabana without any arguments, a stream selector dialog will pop up, allowing you to choose the stream.
