Research direction

Start with the design and open questions in issue #12; this issue names no files, tests, or entry points to begin from. Work includes configurable per-bus bitrate, a vehicle crate or meta.toml declaration, an xtask check, and a decision about refusing read-only access on CAN-FD buses. Done means these requirements are implemented and the CAN-FD behavior is resolved or documented.

Written by the indexing model from the issue text.

Description

Part of https://github.com/OpenCarControls/firmware/issues/12, which has the design and open questions.

  • bitrate in [[hardware.esp.can_buses]]; the vehicle crate or meta.toml declares the expected bitrate per bus and xtask checks it.
  • Refuse to leave read-only on a bus declared CAN-FD (or document why not).
