1 安装Python和Cantools
在Python Releases for Windows | Python.org链接中，找到你需要的Python版本（建议使用3.7及以上版本）下载，并安装。
1.1 查看Python已安装的Package包
快捷键Win + R，打开运行对话框，在其中输入CMD，单击确定。
在弹出的“Windows 命令提示符”窗口，输入命令pip list，可以查看Python已安装的包，及其版本。
1.2 在Python中安装Cantools插件包
在弹出的“Windows 命令提示符”窗口，输入命令pip install cantools，安装Cantools插件包。
Cantools成功安装后提示：
Successfully installed argparse-addons-0.12.0 bitstruct-8.19.0 cantools-39.4.5 crccheck-1.3.0 diskcache-5.6.3 packaging-24.0 python-can-4.3.1 pywin32-306 textparser-0.24.0 typing-extensions-4.10.0 wrapt-1.16.0
使用命令pip list，可以获取Cantools的版本。
1.3 获取更多Cantools工具的更新动态
在GitHub - cantools/cantools: CAN bus tools.链接中，可以关注Cantools该插件最新的更新动态。
2 CAN Matrix Arxml自动生成C语言代码
双击运行批处理文件CAN_Matrix_Arxml_To_C.bat，自动生成两个power_train.c和power_train.h，将这两个文件添加到你的编译环境中，并调用生成的API接口即可。
2.1 批处理文件CAN_Matrix_Arxml_To_C.bat内容说明
CAN_Matrix_Arxml_To_C.bat内容摘录如下，使用该批处理文件需要注意以下四点：
CAN Matrix Arxml文件与批处理文件在同一个目录下；CAN Matrix Arxml文件不能数字，或特殊字符开头，否则生成的代码，不符合C语言语法；使用文本编辑工具，打开批处理文件，将PowerTrain替换成同目录下的Arxml文件名称；使用文本编辑工具，打开批处理文件，将Gateway替换成Arxml中你所使用的发送节点名称。

::CAN Matrix Arxml自动生成C语言代码
python -m cantools generate_c_source -e "gb18030" PowerTrain.arxml --node Gateway
2.2 CAN Matrix Arxml文件要求
这个很重要，决定了能否生成C代码文件，以及生成C代码文件的质量。
以使用的PowerTrain.arxml为例，该批处理文件自动生成的是节点Gateway所收/发的帧和信号的C语言代码。故没有在Tx Frames，Rx Frames出现的帧和信号，不会生成代码。
小结：
在编辑Message和Signal时，需要明确该帧的“发送节点”，以及帧内信号的“接收节点”;并不是所有的CAN Matrix Arxml都可以生成C语言代码，原因是XML的格式(属性标签，分支嵌套结构…)是多变的，Cantools工具无法识别各种Arxml变异，请使用专业工具生成的Arxml文件(AUTOSAR System Description Network Explorer生成的arxml文件有时都无法生成C文件)，如PREEvision
如何准确的制作一个Arxml文件，参考博文【ARXML专题】-2-创建一个Classic CAN（经典CAN2.0）/CANFD的系统描述ARXML文件_新建arxml指令-CSDN博客https://blog.csdn.net/qfmzhu/article/details/111936806
2.3 如何使用生成的C语言代码
API接口****_pack(例如power_train_diag_request_motor_pack)表示将本节点发送的信号的结构体（传参const struct power_train_diag_request_motor_t *src_p）拼接/打包成“字节数组”；
API接口****_unpack (例如power_train_gear_box_info_unpack) 表示将本节点接收的信号的结构体（传参struct power_train_gear_box_info_t *dst_p,），由“字节数组”进行解包得到。
