CANable — connection and CAN FD
Install the CANable package. In Settings → Connections → Transport, select CANable, then set Port and Baudrate CAN to match the bus.
CAN FD
CAN FD mode is available with supported CANable 2.0 firmware. Enable it and set CAN FD data baudrate if the line uses CAN FD. Nominal bitrate and data-phase bitrate are separate settings.
Frame support and application decoding are different capabilities; see CAN FD support. For WeAct USB2CANFD, use the separate WeAct transport.
If the port is not detected, check the cable, use Rescan, and see connection troubleshooting.
