+  server: http://192.168.31.138:8312
+---
+
+## 概述
+
+通过 MinerU API (`http://192.168.31.138:8312`) 分析 PDF/图片/DOCX/PPTX/XLSX 文件。
+
+## API 端点
+
+### 1. 同步解析 `POST /file_parse`
+
+上传文件并等待解析完成，直接返回结果。
+
+```bash
+curl -X POST "http://192.168.31.138:8312/file_parse" \
+  -F "files=@/path/to/document.pdf" \
+  -F "lang_list=ch" \
+  -F "backend=hybrid-auto-engine" \
+  -F "parse_method=auto" \
+  -F "formula_enable=true" \
+  -F "table_enable=true" \
+  -F "image_analysis=true" \
+  -F "return_md=true"
+```
+
+### 2. 异步提交 `POST /tasks`
+
+提交解析任务，立即返回 `task_id`。
+
+```bash
+curl -X POST "http://192.168.31.138:8312/tasks" \
+  -F "files=@/path/to/document.pdf" \
+  -F "lang_list=ch" \
+  -F "backend=hybrid-auto-engine" \
+  -F "return_md=true"
+```
+
+### 3. 查询任务状态 `GET /tasks/{task_id}`
+
+```bash
+curl "http://192.168.31.138:8312/tasks/{task_id}"
+```
+
+返回状态: `pending`, `running`, `completed`, `failed`
+
+### 4. 获取任务结果 `GET /tasks/{task_id}/result`
+
+```bash
+curl "http://192.168.31.138:8312/tasks/{task_id}/result"
+```
+
+### 5. 健康检查 `GET /health`
+
+```bash
+curl "http://192.168.31.138:8312/health"
+```

+API_BASE = "http://192.168.31.138:8312"
+
+# 同步解析
+with open("document.pdf", "rb") as f:
+    resp = requests.post(f"{API_BASE}/file_parse", files=[
+        ("files", ("document.pdf", f, "application/pdf"))
+    ], data={
+        "lang_list": ["ch", "en"],
+        "backend": "hybrid-auto-engine",
+        "formula_enable": True,
+        "table_enable": True,
+        "return_md": True,
+        "return_content_list": True
+    })
+    result = resp.json()
+    print(result.get("md", ""))  # Markdown 内容
+
+# 异步解析
+with open("document.pdf", "rb") as f:
+    resp = requests.post(f"{API_BASE}/tasks", files=[
+        ("files", ("document.pdf", f, "application/pdf"))
+    ], data={"return_md": True})
+    task_id = resp.json()["task_id"]
+
+import time
+while True:
+    status = requests.get(f"{API_BASE}/tasks/{task_id}").json()
+    if status["status"] in ("completed", "failed"):
+        break
+    time.sleep(2)
+
+result = requests.get(f"{API_BASE}/tasks/{task_id}/result").json()
+```
+
+## 使用场景
+
+1. **PDF 转 Markdown** — 提取 PDF 内容为结构化 Markdown
+2. **表格提取** — 从 PDF 中识别并提取表格数据
+3. **公式提取** — 提取数学公式（LaTeX 格式）
+4. **图片分析** — 识别并分析 PDF 中的图片/图表
+5. **OCR 识别** — 扫描件/图片型 PDF 的文字识别
+6. **多语言文档** — 支持中文、英文、日文、韩文、阿拉伯语等多种语言
+7. **分页解析** — 通过 `start_page_id` / `end_page_id` 指定页码范围

-## Code Conventions
- Custom code must be placed within `/* USER CODE BEGIN */` and `/* USER CODE END */` markers
- Code outside these markers will be overwritten by CubeMX code generation
- HAL library is used (defined `USE_HAL_DRIVER` and `STM32F103xB`)
+## MultiButton 按键库
+- **来源**: [0x1abin/MultiButton](https://github.com/0x1abin/MultiButton)

+- **文件**:
+  - `Drivers/BSP/MultiButton/multi_button.c/.h` — 核心库文件
+  - `Drivers/BSP/MultiButton/button_driver.c/.h` — 本项目适配层
+- **定时器**: SysTick 中断中每5ms调用 `button_ticks()`
+- **使用示例**:
+  ```c
+  /* 在回调函数中处理按键事件 */
+  static void button_key1_callback(Button* handle, void* user_data) {
+      HAL_GPIO_TogglePin(LED_GPIO_Port, LED_Pin);
+      printf("KEY1: LED翻转\n");
+  }
+  
+  /* 初始化时注册回调 */
+  button_attach(&btn_handle, BTN_SINGLE_CLICK, button_key1_callback, NULL);
+  ```
