The full story
Most CAN bus data in vehicles is undocumented, and finding where a single signal lives can take hours. Martin Falch of CSS Electronics shows a Claude Code skill that surveys the bus, compares candidate bits against a reference, pins down the exact field and outputs a DBC file.
Three demos decode speed and RPM against an OBD2 reference in under five minutes, vehicle speed from dashboard video, and gauge positions from a simple reference app.
