+# 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
+```
+
+## 📚 新增文件说明
+
+### CMakeLists.txt
+- 标准CMake构建配置
+- 支持静态库编译
+- 可选的示例程序编译
+- 安装规则
+
+### README.md
+- 模块使用文档
+- API说明
+- 编译指南
+- 示例代码
+
+### build.sh
+- 快速构建脚本
+- 自动化编译流程
+- 支持清理构建
+- 彩色输出
+
+### .gitignore
+- Git版本控制忽略配置
+- 排除编译产物
+- 排除IDE配置
+
+### 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。
