-# 设备配置HTTP API使用示例
-
-本文档展示如何通过HTTP API来设置和获取设备参数。
-
-## API端点
-
-基础URL: `http://localhost:5002/api/config`
-
-## 1. 获取所有设备配置
-
-**GET** `/devices`
-
-```bash
-curl -X GET http://localhost:5002/api/config/devices
-```
-
-**响应示例:**
-```json
-{
-  "success": true,
-  "data": {
-    "imu": {
-      "device_type": "real",
-      "port": "COM6",
-      "baudrate": 9600,
-      "timeout": 1.0,
-      "calibration_samples": 100
-    },
-    "pressure": {

-    "device_type": "real",
-    "port": "COM6",
-    "baudrate": 9600,
-    "timeout": 1.0,
-    "calibration_samples": 100
-  }
-}
-```
-
-## 4. 设置压力板配置
-
-**POST** `/devices/pressure`
-
-```bash
-curl -X POST http://localhost:5002/api/config/devices/pressure \

-    "use_mock": false,
-    "port": "COM5",
-    "baudrate": 115200
-  }'
-```

-    "device_index": 1,
-    "width": 1280,
-    "height": 720,
-    "fps": 30
-  }'
-```
-
-**请求参数:**
-- `device_index`: 相机设备索引 (如 1)

-
-## 错误处理
-
-当请求失败时，API会返回错误信息:
-
-```json
-{
-  "success": false,
-  "message": "错误描述"
-}
-```
-
-常见的HTTP状态码:
-- `200`: 成功
-- `400`: 请求参数错误
-- `500`: 服务器内部错误
-
-## 启动配置API服务
-
-```bash
-# 进入设备目录
-cd backend/devices
-
-# 运行配置API服务
-python config_api.py
-```
-
-服务将在 `http://localhost:5002` 启动。
-
-## Python客户端示例
-
-```python
-import requests
-import json
-
-# 设置IMU配置
-def set_imu_config():
-    url = "http://localhost:5002/api/config/devices/imu"
-    data = {

-
-# 获取所有设备配置
-def get_all_configs():
