This project shows you how to setup Wireshark for use with the PiCAN board to capture data on the Raspberry Pi.
Install the CAN drivers according to this:
Make sure the command line candump works first.
sudo apt-get install wireshark
Bring up the CAN interface and start the GUI.
ip link set can0 up type can bitrate 500000
Start Wireshark, the icon is under “Other”.
Select the 1. “can0″ interface then click the 2. “Start a new live capture” icon.
Ensure the PiCAN is connected to an active CAN line you should see data like this:
It would be nice if Wireshark can decode a list of PIDs.
