# 本页将介绍LibXR的代码生成器(CodeGenerator)的使用方法。
8+
9+
CodeGenerator本质上是根据SDK的工程文件生成对应的代码，例如依靠STM32CubeMX的IOC文件，生成相应的C++外设初始化代码。

# STM32 代码生成
8+
9+
LibXR 提供 `xr_cubemx_cfg` 命令用于从 STM32CubeMX 工程中一键生成符合 LibXR 架构的 C++ 初始化代码。该命令集成了配置解析、代码生成、中断补丁、CMake 集成等多个子工具。
10+
11+
---
12+
13+
## 快速使用
14+
15+
在 STM32CubeMX 工程根目录下执行：
16+
17+
```bash
18+
xr_cubemx_cfg -d .
19+
```
20+
21+
该命令将自动完成以下流程：
22+
23+
1. 初始化或更新 `libxr` 子模块；
24+
2. 查找 `.ioc` 文件并解析为 `.config.yaml`；
25+
3. 生成 `app_main.cpp` 初始化代码；
26+
4. 补丁中断处理函数；
27+
5. 修改 `CMakeLists.txt`，集成 LibXR 构建配置。

# This page introduces how to use the `CodeGenerator` in LibXR.
8+
9+
The `CodeGenerator` essentially generates corresponding source code based on the SDK's project files. For example, it can use an STM32CubeMX IOC file to generate the relevant C++ peripheral initialization code.

# STM32 Code Generation
8+
9+
LibXR provides the `xr_cubemx_cfg` command to automatically generate C++ initialization code from an STM32CubeMX project. This command wraps several tools including configuration parsing, code generation, interrupt patching, and CMake integration.
10+
11+
---
12+
13+
## Quick Start
14+
15+
In the root directory of your STM32CubeMX project, run:
16+
17+
```bash
18+
xr_cubemx_cfg -d .
19+
```
20+
21+
This command will perform the following steps automatically:
22+
23+
1. Initialize or update the `libxr` submodule
24+
2. Locate the `.ioc` file and convert it into `.config.yaml`
25+
3. Generate `app_main.cpp` with initialization code
26+
4. Patch interrupt handler files
27+
5. Modify `CMakeLists.txt` to integrate LibXR
28+
29+
---
30+
31+
## Example Output
32+
33+
```text
34+
[INFO] LibXR submodule already exists. Checking for updates...
35+
[INFO] [OK] cd . && git submodule update --init --recursive
36+
[INFO] LibXR submodule updated.
37+
Found .ioc file: .\atom.ioc
38+
Parsing .ioc file...
39+
[INFO] [OK] xr_parse_ioc -d . -o .\.config.yaml
40+
Generating C++ code...
41+
[INFO] [OK] xr_gen_code_stm32 -i .\.config.yaml -o .\User\app_main.cpp
42+
Modifying STM32 interrupt files...
43+
[INFO] [OK] xr_stm32_it .\Core/Src
44+
[INFO] [OK] xr_stm32_cmake .
45+
[INFO] [Pass] All tasks completed successfully!
46+
```
47+
48+
---
49+
50+
## Output Structure
51+
52+
After execution, your project directory will contain the following generated or modified files:
53+
54+
```txt
55+
.
56+

57+
├── User/
58+
