+# Shake Detection 模块迁移说明
+
+## 📦 迁移概述
+
+shake_detection模块已从 `drivers/acc/` 迁移到独立的 `zhihui/shake/` 目录，并重新组织了目录结构。
+
+## 🔄 目录结构变更
+
+### 旧目录结构
+```
+zhihui/drivers/acc/
+├── shake_detection.h
+├── shake_detection.c
+├── shake_detection_at_cmd.c
+└── shake_detection_example.c
+```
+
+### 新目录结构 ✅
+```
+zhihui/shake/
+├── include/
+│ └── shake_detection.h # 头文件
+├── src/
+│ ├── shake_detection.c # 核心实现
+│ └── shake_detection_at_cmd.c # AT命令接口
+├── example/
+│ └── shake_detection_example.c # 示例程序
+├── CMakeLists.txt # CMake构建配置
+├── README.md # 模块文档
+├── .gitignore # Git忽略配置
+├── build.sh # 快速构建脚本
+└── MIGRATION.md # 本文档
+```
+
+## 📝 文件移动记录
+
+| 原路径 | 新路径 | 说明 |
+|-------|--------|------|
+| `drivers/acc/shake_detection.h` | `shake/include/shake_detection.h` | 头文件 |
+| `drivers/acc/shake_detection.c` | `shake/src/shake_detection.c` | 实现文件 |
+| `drivers/acc/shake_detection_at_cmd.c` | `shake/src/shake_detection_at_cmd.c` | AT命令 |
+| `drivers/acc/shake_detection_example.c` | `shake/example/shake_detection_example.c` | 示例 |
+
+## 🔧 代码修改指南
+
+### 1. 包含路径更新
+
+**旧代码：**
+```c
+#include "drivers/acc/shake_detection.h"
+```
+
+**新代码：**
+```c
+#include "shake_detection.h"
+```
+
+### 2. CMake集成
+
+**在你的 CMakeLists.txt 中添加：**
+
+```cmake
+# 添加shake子目录
+add_subdirectory(zhihui/shake)
+
+# 链接shake_detection库
+target_link_libraries(your_application
+ shake_detection
+)
+
+# 包含头文件目录（如果需要）
+target_include_directories(your_application PRIVATE
+ ${CMAKE_SOURCE_DIR}/zhihui/shake/include
+)
+```
+
+### 3. Makefile集成
+
+**添加到你的 Makefile：**
+
+```makefile
+# 包含shake头文件
+INCLUDES += -I$(SDK_ROOT)/zhihui/shake/include
+
+# 链接shake库
+LIBS += -L$(SDK_ROOT)/zhihui/shake/build -lshake_detection
+
+# 或者直接包含源文件
+SOURCES += \
+ $(SDK_ROOT)/zhihui/shake/src/shake_detection.c \
+ $(SDK_ROOT)/zhihui/shake/src/shake_detection_at_cmd.c
+```
+
+## 🚀 快速编译
+
+### 方法1：使用构建脚本（推荐）
+
+```bash
+cd zhihui/shake
+./build.sh
+```
+
+**选项：**
+```bash
+./build.sh --clean # 清理后重新编译
+./build.sh --no-examples # 不编译示例
+./build.sh --help # 显示帮助
+```
+
+### 方法2：手动使用CMake
+
+```bash
+cd zhihui/shake
+mkdir build && cd build
+cmake ..
+make -j$(nproc)
+```
+
+### 方法3：只编译库
+
+```bash
+cd zhihui/shake
+mkdir build && cd build
+cmake -DBUILD_SHAKE_EXAMPLES=OFF ..
+make
+```
+

+
+### MIGRATION.md（本文档）
+- 迁移指南
+- 目录结构说明
+- 代码修改指导
+
+## ⚠️ 注意事项
+
+### 1. 依赖更新
+如果你的代码依赖于shake_detection模块，需要：
+- 更新包含路径
+- 更新CMake配置
+- 重新编译项目
+
+### 2. 头文件路径
+新的头文件路径更简洁：
+```c
+// 旧的（可能需要长路径）
+#include "drivers/acc/shake_detection.h"
+
+// 新的（简短路径）
+#include "shake_detection.h"
+```
+
+### 3. 编译输出
+编译后的文件位于：
+- 静态库：`build/libshake_detection.a`
+- 示例程序：`build/shake_detection_example`
+
+### 4. 安装位置
+如果执行 `make install`，文件将安装到：
+- 头文件：`/usr/local/include/shake/`
+- 库文件：`/usr/local/lib/`
+
+## 🔍 验证迁移
+
+### 1. 检查文件是否存在
+```bash
+cd zhihui/shake
+ls -la include/ src/ example/
+```
+
+### 2. 测试编译
+```bash
+cd zhihui/shake
+./build.sh
+```
+
+### 3. 运行示例
+```bash
+cd zhihui/shake/build
+./shake_detection_example
+```
+
+## 📊 统计信息
+
+- **文件数量：** 4个源文件 + 3个配置文件
+- **代码行数：** ~1000行
+- **目录层级：** 3层（include/src/example）
+- **构建系统：** CMake 3.10+
+
+## 🐛 常见问题
+
+### Q1: 找不到头文件
+**A:** 确保在CMake中正确添加了包含目录：
+```cmake
+target_include_directories(your_app PRIVATE
+ ${CMAKE_SOURCE_DIR}/zhihui/shake/include
+)
+```
+
+### Q2: 链接错误
+**A:** 确保正确链接了shake_detection库：
+```cmake
+target_link_libraries(your_app shake_detection)
+```
+
+### Q3: 旧代码编译失败
+**A:** 更新所有 `#include` 路径为新路径，并重新配置CMake。
+
+## 📞 支持
