CSS Electronics: reverse-engineering CAN bus signals with a Claude Code skill
Martin Falch of CSS Electronics shows a Claude Code skill that decodes proprietary CAN signals into DBC files with a CANsub.2 interface. The skill matches bus bits against a reference, such as OBD2 data, dashboard video read by OCR or hand-logged gauge positions, and fits scale and offset. The 31-minute video runs it on car logs and a gauge bench.
