canbus-integration

canbus-integration is a skill for Claude Code, Codex from easyzoom/aix-skills. It costs 41 tokens per session (706 once invoked), scanned A, original, MIT.

A guide for integrating and debugging CAN bus communication, a system where embedded devices exchange short messages over a shared wired network. It covers controllers, transceivers, message frames, timing, filters, and automotive protocols.

In plain words
What is it for?
Use it to configure or troubleshoot CAN libraries, MCP2515 and SocketCAN hardware, CANBus-Triple projects, message IDs, filters, bit timing, termination, CAN FD, and automotive protocols.
Why use it?
It helps separate wiring and electrical problems from software or protocol problems. This matters when messages are missing, rejected, sent with the wrong IDs, or when the bus enters a fault state.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

canbus-integration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

CANBus Integration

Overview

Use this skill for embedded CAN bus libraries and CANBus-Triple style projects. CAN failures are often physical-layer, bit-timing, termination, transceiver, or filter problems before they are application protocol problems.

When To Use

Use this skill when:

  • The user mentions CAN, CANBus-Triple, MCP2515, SocketCAN, CANopen, J1939, UDS, OBD-II, ISO-TP, or automotive messages.
  • Frames are missing, bus-off occurs, IDs are wrong, filters reject messages, or bit timing is unreliable.
  • The task involves adapting a CAN example project or Arduino-style CAN platform to another board.

Do not use this skill when the target is only a generic UART/SPI issue with no CAN layer.

First Questions

Ask for:

  • CAN controller/transceiver and board, such as internal CAN, FDCAN, MCP2515, or CANBus-Triple.
  • Bus speed, oscillator frequency, sample point, and whether CAN FD is involved.
  • Wiring, termination, transceiver voltage, and whether another known-good node is present.
  • Frame IDs, standard/extended format, filters, masks, and expected traffic.
  • Library/project source and current error counters, bus state, or capture.

Integration Checklist

  1. Verify physical layer. Confirm CANH/CANL wiring, 120-ohm termination, common ground, transceiver enable/standby, and voltage compatibility.

  2. Confirm bit timing. Controller clock, prescaler, segments, sample point, and bus speed must match the network.

  3. Start with listen or loopback. Use internal loopback or listen-only mode before transmitting onto a live bus.

  4. Configure filters deliberately. Disable filters temporarily or accept all frames to prove RX path before narrowing IDs.

  5. Separate transport and protocol. First prove raw CAN frames, then add ISO-TP, UDS, OBD-II, J1939, or application decoding.

  6. Protect live systems. Do not transmit on vehicle or production buses without explicit approval and a safe test plan.

Common Failures

  • Missing termination or wrong transceiver standby pin.
  • MCP2515 oscillator frequency differs from library assumption.
  • Standard versus extended ID mismatch.
  • Filters silently drop expected frames.
  • Bus-off caused by transmitting at wrong bit rate.
  • SPI-to-CAN driver works in loopback but fails due to transceiver wiring.

canbus-integration is a skill published in the GitHub repository easyzoom/aix-skills (31 stars, last pushed 1mo ago), licensed MIT. It adds 41 tokens to every session and 706 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
