Its CLI decodes candump output against a database, plots decoded signals from candump logs with matplotlib, dumps each message's bit layout, converts between database formats, generates C pack and unpack code, and monitors a live bus in a text interface through python-can.",

    "Latest release at review: 45.1.0, published 2026-10-20 on GitHub and PyPI; the reviewed master commit is 15 commits ahead of that tag. It installs with pip, and pyproject.toml requires Python 3.10+ with python-can, bitstruct, textparser, crccheck and argparse_addons, plus optional extras for plotting (matplotlib), caching (diskcache) and Windows curses support for the monitor.",
    "Bring a database describing the target network and frames captured from it: decode reads candump output on standard input and plot reads candump log files, while monitor takes python-can bus arguments for a live interface, and the README's scripting example sends and receives frames on a SocketCAN channel. The repository's tests/files directory holds sample DBC, KCD, SYM, ARXML and CDD databases and generated C sources used by the examples and tests.",
    "Decoding covers only what the supplied database defines; cantools applies existing message and signal definitions rather than inferring unknown layouts, and the README notes that generated C code is limited to signals of at most 64 bits. MIT licensed."

    "审阅时最新版本为 45.1.0，于 2026-10-20 发布在 GitHub 和 PyPI；所审阅的 master 提交比该标签多 15 个提交。可用 pip 安装；pyproject.toml 要求 Python 3.10+，依赖 python-can、bitstruct、textparser、crccheck 和 argparse_addons，并提供绘图（matplotlib）、缓存（diskcache）以及监视器所需 Windows curses 支持等可选扩展。",
    "需要自备描述目标网络的数据库以及从该网络采集的帧：decode 从标准输入读取 candump 输出，plot 读取 candump 日志文件，monitor 则通过 python-can 的总线参数连接实时接口；README 中的脚本示例在 SocketCAN 通道上收发帧。仓库的 tests/files 目录收录示例和测试所用的 DBC、KCD、SYM、ARXML 和 CDD 示例数据库以及生成的 C 源码。",
    "解码范围仅限所提供数据库中定义的内容；cantools 应用现有的报文和信号定义，并不推断未知布局；README 还指出生成的 C 代码仅支持不超过 64 位的信号。采用 MIT 许可。"
