# Coglet 项目分析与开发指南
## 一、项目简介
**Coglet** 是 YouTube 创作者 Will Cogley（原 Nilheim Mechatronics）开发的 **DIY 桌面 AI 伴侣机器人**，目前在 Kickstarter 众筹中。项目包含 3D 打印外壳、PCB 电路板和双 MCU 软件系统。
### 系统架构
采用**双 MCU 架构**，三个核心模块通过 UART 串联：
```
ESP32-S3 ←── UART 115200 ──→ RP2040 (Pico) ←── UART 921600 ──→ Grove Vision AI V2
(AI/语音/网络) (舵机/动画) (摄像头/人脸检测)
```
| 芯片 | 职责 |
|------|------|
| **ESP32-S3** | AI 对话、语音识别/合成、WiFi 网络、MCP 协议（基于小智 XiaoZhi 固件） |
| **RP2040 (Raspberry Pi Pico)** | 9 个舵机控制、动画表情、人脸追踪（MicroPython） |
| **Grove Vision AI V2** | 摄像头人脸检测 |
### ESP32 固件核心功能
- 连接方式：WiFi / ML307 Cat.1 4G
- 语音交互：流式 ASR + LLM（Qwen/DeepSeek）+ TTS
- 离线唤醒：ESP-SR 本地语音唤醒
- 通信协议：WebSocket 或 MQTT+UDP
- 音频编码：OPUS
- 显示：OLED/LCD + 表情动画
- 多语言：中文/英文/日文
- MCP 协议：设备端 MCP（控制扬声器、LED、舵机、GPIO）+ 云端 MCP（智能家居）
### RP2040 控制的舵机（共 9 个）
| 舵机代号 | 功能 |
|---------|------|
| EYL / EYR | 左右眼水平转动 |
| PIT | 头部俯仰 |
| YAW | 头部偏航 |
| MOU | 嘴巴开合 |
| LID | 眼睑眨眼 |
| 其他 | 耳朵舵机等 |
### RP2040 状态机
`idle` → `speaking` → `listening` → `thinking` → `happy` → `neutral` → `calibration`

### CogletESP 分支列表
| 分支名 | Commits | 说明 |
|--------|---------|------|
| `main` | 789 | 上游同步的主分支 |
| **`CogletESP`** | 758 | **Coglet 专用分支（无 ESP32 摄像头版本，保留 LCD 显示）** |
| **`camera-version`** | 755 | **ESP32 OV3660 摄像头版本（需 PCB 飞线，禁用 LCD）** |
| `esp32_camera` | - | ESP32 摄像头分支 |
| `v1` | 669 | v1 稳定版 |
| `bed-operator` | - | 功能分支 |
| `fix_resampler` | - | 重采样器修复 |
| `fix_rndis` | - | RNDIS 修复 |
| `listening_wakeword` | - | 唤醒词监听 |
| `nt26_board` | - | NT26 开发板适配 |
### CogletESP 分支 vs camera-version 分支（关键区别）
> **重要区分**：这里的"摄像头"指 **ESP32-S3 上直连的 OV3660 DVP 摄像头**（小智 AI 视觉功能），**不是** Grove Vision AI V2。Grove Vision AI V2 是独立模块接在 RP2040 上，两个分支都支持它。
两个分支仅 **2 个文件**不同，都在 `main/boards/bread-compact-wifi-s3cam/` 目录下：
| 对比项 | `CogletESP` 分支 | `camera-version` 分支 |
|--------|------------------|----------------------|
| ESP32 摄像头(OV3660) | 默认引脚，与 PSRAM 冲突 | 飞线后的新引脚映射 |
| LCD 显示 | 正常支持 | **禁用**（引脚被摄像头占用，用 DummyDisplay 替代） |
| PCB 改动 | 无需飞线 | **需要 3 根飞线**（35→14, 36→41, 37→42） |
| 摄像头画面 | - | 设置 HMirror + VFlip 翻转 |
| JTAG 引脚(GPIO 39-42) | 默认用途 | 释放给摄像头使用 |
| Grove Vision AI V2 | 支持 | 支持 |
#### GPIO 引脚映射差异（部分关键引脚）
| 功能 | `CogletESP` 分支 | `camera-version` 分支 |
|------|------------------|----------------------|
| MIC_WS | GPIO 1 | GPIO 4 |
| MIC_SCK | GPIO 2 | GPIO 5 |
| MIC_DIN | GPIO 42 | GPIO 6 |
| SPK_DOUT | GPIO 39 | GPIO 7 |
| SPK_BCLK | GPIO 40 | GPIO 15 |
| SPK_LRCK | GPIO 41 | GPIO 16 |
| LED | GPIO 48 | GPIO 3 |
| CAMERA D7 | GPIO 16 | GPIO 14（飞线 35→14） |
| CAMERA VSYNC | GPIO 6 | GPIO 41（飞线 36→41） |
| CAMERA HREF | GPIO 7 | GPIO 42（飞线 37→42） |
#### 如何选择分支？
- **带 ESP32 OV3660 摄像头** → 用 `camera-version` 分支 + PCB 做 3 根飞线，但**没有 LCD 屏**
- **不带 ESP32 摄像头 / 想保留 LCD 屏** → 用 `CogletESP` 分支
- **仅使用 Grove Vision AI V2 人脸追踪** → 两个分支都可以，这是 RP2040 端的功能，与 ESP32 分支无关

---
## 四、摄像头版本完整搭建流程（camera-version）
> 你使用的是**带摄像头**的版本，以下是从零到运行的完整操作流程。
### 4.1 为什么需要飞线？
**这是 CogNog V1.0 PCB 的设计缺陷，不是故意的设计。**
ESP32-S3 的 PSRAM 使用 Octal SPI 接口，占用了 GPIO 35/36/37。但 V1.0 PCB 把摄像头的三个信号线（D7、VSYNC、HREF）也接到了这三个引脚上。当摄像头和 PSRAM 同时工作时，引脚冲突导致摄像头无法使用。
**所有使用 CogNog V1.0 PCB + 摄像头的用户都必须飞线。** 目前只有 V1.0 版本的 PCB。
### 4.2 硬件准备清单
| 部件 | 说明 |
|------|------|
| CogNog V1.0 PCB | 需要飞线修改 |
| ESP32-S3 模组 | 带 PSRAM（如 N16R8） |
| OV3660 摄像头模组 | DVP 接口 + 排线 + 转接板 |
| Grove Vision AI V2 | 人脸追踪模块 + 15pin 排线适配器 |
| INMP441 麦克风 | I2S 数字麦克风 |
| 扬声器 | I2S 输出 |
| 9x 舵机 | **必须 180° 标准舵机**（如 KPower M0090 或 MG90S 180° 金属齿轮版），详见下方舵机选型说明 |
| Raspberry Pi Pico (RP2040) | 舵机控制 |
| 6 Pin PicoBlade 连接线 | RP2040 ↔ ESP32 UART |
### 4.3 PCB 飞线操作（3 根线）
在 CogNog V1.0 PCB 上，**切断原走线并飞线到新引脚**：
| 原始引脚 | 飞线到 | 摄像头信号 | 说明 |
|----------|--------|-----------|------|
| GPIO 35 | **GPIO 14** | CAMERA_PIN_D7 | 数据位 7 |
| GPIO 36 | **GPIO 41** | CAMERA_PIN_VSYNC | 垂直同步 |
| GPIO 37 | **GPIO 42** | CAMERA_PIN_HREF | 行参考信号 |
> **注意**：camera-version 分支还释放了 JTAG 引脚（GPIO 39-42）给摄像头使用，代码中通过 `gpio_reset_pin()` 实现。
### 4.4 代码下载
```bash
# 第 1 步：克隆 camera-version 分支（ESP32 固件 + RP2040 代码都在里面）
git clone -b camera-version https://github.com/will-cogley/CogletESP.git

### 4.5 编译烧录 ESP32 固件（macOS）
```bash
# 1. 进入项目目录
cd CogletESP
# 2. 激活 IDF 环境
source ~/esp/esp-idf/export.sh
# 3. 设置目标芯片
idf.py set-target esp32s3
# 4. 配置板级选项
idf.py menuconfig
# → 找到板级配置，选择 bread-compact-wifi-s3cam
# 5. 编译
idf.py build
# 6. 查看可用串口
ls /dev/cu.usb*
# 7. 烧录并监控
idf.py -p /dev/cu.usbmodem14101 flash monitor
# 串口名根据实际替换（/dev/cu.usbmodem* 或 /dev/cu.usbserial*）
# 8. 退出监视器：Ctrl + ]
```
### 4.6 烧录 RP2040（MicroPython）
**第 1 步：刷入 MicroPython 固件**
下载地址：https://micropython.org/download/RPI_PICO/
**版本选择**：下载 **v1.24.x ~ v1.25.x 稳定版** `.uf2` 文件。代码只用基础 API（Pin、PWM、UART），v1.20+ 稳定版都兼容。**不要下载 preview/nightly 预览版。**
**硬件说明**：CogNog V1.0 PCB 上 RP2040 是直接焊接的（不是独立的 Raspberry Pi Pico 开发板），PCB 上有两个相关按键：
- **SW1（Boot Switch）**：位于 Flash Memory 旁，即 BOOTSEL 功能，用于进入 UF2 烧录模式
- **Run Switch**：位于 RP2040 旁，连接 RUN 引脚，即**复位按钮**。使用场景：
- 上传新的 .py 文件后，按一下重启 RP2040 使新代码生效（等同于 `mpremote reset`）
- 舵机行为异常时，按一下重启恢复到初始状态
- 配合 SW1 进入烧录模式（见下方方式 B）
操作（macOS / Windows 通用）：
**方式 A — USB 未连接时：**
1. **按住 SW1（Boot Switch）** → 通过 RP2040 的 USB-C 口连接电脑 → 松开 SW1
2. 电脑上出现 `RPI-RP2` U 盘（macOS 在 Finder，Windows 在资源管理器）
3. 将 `.uf2` 文件拖入 U 盘
4. RP2040 自动重启
**方式 B — USB 已连接时（更常用）：**
1. **按住 SW1（Boot Switch）不松手**
2. **按一下 Run Switch（复位）然后松开**（只按一下，不用保持）
3. **松开 SW1** — 整个过程约 1-2 秒，关键是按 Run Switch 时 SW1 必须处于按下状态
4. 电脑上出现 `RPI-RP2` U 盘
5. 将 `.uf2` 文件拖入 U 盘
6. RP2040 自动重启
> **原理**：Run Switch 让 RP2040 复位重启，重启瞬间 SW1 被按着 → RP2040 检测到 BOOTSEL 为低电平 → 进入 UF2 bootloader 模式。
>
> **提示**：如果 RP2040 已经刷过 MicroPython 且只需要更新 .py 文件，不需要重新进入 bootloader 模式，直接用 `mpremote` 上传即可（见第 2 步）。
**第 2 步：上传 .py 文件**
> **注意**：`CogletESP` 分支有 4 个文件（含 `coms.py`），`camera-version` 分支有 3 个文件（无 `coms.py`）。请使用对应分支的文件。
#### macOS
方式 A — mpremote（推荐）：
```bash
pip install mpremote
cd CogletESP/RP2040
mpremote cp main.py :main.py
mpremote cp servoclass.py :servoclass.py
mpremote cp coms.py :coms.py # 仅 CogletESP 分支需要
mpremote cp animation.py :animation.py
mpremote reset # 重启运行
mpremote repl # 查看串口输出（调试用）
```
mpremote 本质就是一个串口文件传输工具，把 .py 文件拷贝到 Pico 的文件系统里。Pico 上电后自动运行 main.py，不需要搭建任何 MicroPython 编译环境。
方式 B — Thonny（图形界面）：
```bash
brew install --cask thonny
```
1. 打开 Thonny → 右下角选择 `MicroPython (Raspberry Pi Pico)`
2. 逐个打开 .py 文件 → 另存为 → 选择 `Raspberry Pi Pico` → 保存同名
3. 保存完成后 Pico 重启自动运行 `main.py`
#### Windows
方式 A — mpremote（推荐）：
```powershell
# 1. 安装 mpremote（需要 Python 3.x，从 python.org 下载安装，勾选 Add to PATH）
pip install mpremote
# 2. 进入 RP2040 目录
cd CogletESP\RP2040
# 3. 上传文件（Pico 连接 USB 后 Windows 会分配 COM 口，mpremote 自动识别）
mpremote cp main.py :main.py
mpremote cp servoclass.py :servoclass.py
mpremote cp coms.py :coms.py # 仅 CogletESP 分支需要
mpremote cp animation.py :animation.py
mpremote reset # 重启运行
mpremote repl # 查看串口输出（调试用，Ctrl+] 退出）
```
> **Windows 注意事项**：
> - 如果 `mpremote` 找不到设备，打开**设备管理器 → 端口(COM 和 LPT)**，确认 Pico 对应的 COM 口（如 COM3），然后用 `mpremote connect COM3 cp main.py :main.py` 指定端口
> - 如果设备管理器中看不到 COM 口，需要安装驱动：MicroPython 固件刷入后 Pico 通常免驱，若未识别可尝试拔插 USB 或换 USB 口
方式 B — Thonny（图形界面，适合新手）：
1. 下载安装 Thonny：https://thonny.org/ （选择 Windows 版本）
2. 打开 Thonny → 右下角选择 `MicroPython (Raspberry Pi Pico)`
3. 逐个打开 .py 文件 → 文件 → 另存为 → 选择 `Raspberry Pi Pico` → 保存同名
4. 保存完成后 Pico 重启自动运行 `main.py`
### 4.7 配置 Grove Vision AI V2（人脸追踪）
**不需要手动刷底层固件**，但需要部署一个人脸检测模型。
**操作步骤：**
1. 用 USB-C 线将 Grove Vision AI V2 连接到电脑
2. 用 Chrome 浏览器访问 **SenseCraft AI 平台**：https://sensecraft.seeed.cc/
3. 模型下载地址：https://sensecraft.seeed.cc/ai/model/deploy?id=60094&uniform_type=36&name=%E4%BA%BA%E8%84%B8%E6%A3%80%E6%B5%8B&adapteds=11&adapteds=12&adapteds=14&task=1
4. 选择一个**人脸检测模型**（推荐 YOLO Face Detection，输入尺寸 **224x224**）
5. 点击部署，等待上传完成
6. 断开 USB，将模块接回 RP2040 的 UART
**为什么是 224x224？** 代码中 `pixel_centre = 112` 即 224/2，表明模型输入分辨率为 224x224。
**工作原理：**
```
RP2040 发送 AT+INVOKE=1,0,1 (SSCMA AT 协议)
↓
Grove Vision AI V2 运行人脸检测推理
↓
返回 JSON，包含 "boxes" 字段 → [x, y, w, h, ...]
↓
RP2040 计算人脸偏移量：x_offset = boxes[0] - 112, y_offset = boxes[1] - 112
↓
驱动舵机追踪：
- EYL/EYR（眼球左右） → 跟随 x_offset
- PIT（头部俯仰） → 跟随 y_offset
- YAW（底座旋转） → 眼球偏离中心 >20° 时延迟跟随
↓
deadzone = 20 像素（避免微小抖动触发舵机）
```

ESP32 通过 UART 发送状态字符串给 RP2040：
`neutral` / `idle` / `listening` / `speaking` / `thinking` / `happy`
→ RP2040 根据状态执行对应舵机动画
### 4.9 舵机选型说明（重要）
> **实测踩坑记录**：使用 MG90S 360° 连续旋转版舵机后，耳朵舵机转到目标角度后无法停止，持续堵转导致齿轮发出刺耳声音、舵机严重发烫，有烧毁风险。更换为 180° 标准舵机后问题解决。
#### 必须使用 180° 标准舵机的原因
Coglet 的 9 个舵机全部采用**角度控制**模式（代码中 `set_target(角度)` 命令舵机转到指定角度并保持），这只有 180° 标准舵机才能实现。
**180° 标准舵机 vs 360° 连续旋转舵机的核心区别：**
| 对比项 | 180° 标准舵机（如 KPower M0090） | 360° 连续旋转舵机（如 MG90S 360° 改装版） |
|--------|-------------------------------|-------------------------------------|
| **内部结构** | 有电位器（可变电阻），实时反馈当前角度 | 拆除/固定了电位器，失去角度反馈能力 |
| **PWM 信号含义** | 对应**目标角度**（1ms=0°, 1.5ms=90°, 2ms=180°） | 对应**旋转速度和方向**（1.5ms=停止, <1.5ms=反转, >1.5ms=正转） |
| **控制逻辑** | 闭环控制：收到 PWM → 对比目标与当前角度 → 自动转到位停住 | 开环控制：收到 PWM → 按速度持续旋转，永不停止 |
| **能否锁定位置** | 能，到达角度后施力保持 | 不能，停转后无保持力，外力可推动 |
| **旋转范围** | 0°~180° 精确定位 | 360° 无限旋转，无法精确定位 |
#### 为什么 360° 舵机无法通过代码适配？
网上有"定时转动"方案（全速旋转 N 毫秒 → 发停止信号），原理是 `转动时间 = (500ms / 360°) × 目标角度`。但这对 Coglet **完全不可行**：
1. **误差累积无法修正**：没有位置反馈，每次转动误差 ±5°~10°。Coglet 的动画是高频反复运动（说话时嘴巴每 250ms 开合一次、耳朵每秒摆动），运行几分钟后累积误差可达几百度，位置完全跑飞
2. **个体差异大**：每台舵机电机特性、齿轮间隙不同，无法统一校准"时间-角度"关系。换一台舵机就要重新标定
3. **无法保持位置**：代码中头部俯仰、眼球等需要停在某个角度并持续施力保持。360° 舵机停转后没有保持力，手一碰就偏了
4. **实时性失效**：Coglet 需要实时响应 AI 状态变化动态调整角度，定时方案无法做到实时同步
5. **负载和温度影响转速**：电压波动、温度变化都会改变旋转速度，使时间估算更不准确
#### 推荐舵机型号
| 型号 | 说明 | 参考价格 |
|------|------|---------|
| **KPower M0090**（官方推荐） | 9g 模拟金属齿轮 180° 舵机 | ~¥8-12/个 |
| **MG90S 180° 金属齿轮版** | 注意必须是 **180° 版**，不带 "continuous/360" 字样 | ~¥5-8/个 |
> **购买注意**：MG90S 有 180° 和 360° 两个版本，外观完全一样。购买时务必确认商品标题或参数中标注 "180°"，避免买到 360° 连续旋转版。
#### 9 个舵机角度范围详解
代码中所有舵机的 PWM 映射为 0°~180°（脉宽 500μs~2500μs），各舵机通过 `min_angle` / `max_angle` 限定实际运动范围（源码：`animation.py` 第 14-23 行）：
| 舵机代号 | 功能 | GPIO 引脚 | 角度范围 | 最大跨度 | 运动说明 |
|---------|------|----------|---------|---------|---------|
| **YAW** | 底座旋转 | GP6 | 10°~170° | 160° | 头部左右转动，人脸追踪时由 Grove Vision AI V2 驱动 |
| **ROL** | 颈部侧倾 | GP7 | 30°~120° | 90° | 头部左右歪头，happy 状态下 70°↔110° 摆动 |
| **PIT** | 头部俯仰 | GP8 | 1°~80° | 79° | 头部上下点头，thinking 状态下 50°↔80° 摆动 |
| **MOU** | 嘴巴开合 | GP19 | 5°~150° | 145° | speaking 时 70°↔130° 每 250ms 切换（张嘴/闭嘴） |
| **EYL** | 左眼球 | GP12 | 30°~150° | 120° | 左右看，人脸追踪时跟随 x 偏移量 |
| **EYR** | 右眼球 | GP13 | 30°~150° | 120° | 与 EYL 同步运动 |
| **LID** | 眼睑 | GP14 | 30°~160° | 130° | 30°=闭眼，110°~160°=睁眼，随机眨眼动画 |
| **EAL** | 左耳 | GP15 | 60°~150° | 90° | happy 状态下 100°↔160° 摆动 |
| **EAR** | 右耳 | GP16 | 30°~120° | 90° | happy 状态下 60°↔120° 摆动 |
> **注意**：以上角度范围是代码中的软件限位，基于官方 3D 打印件和 KPower M0090 舵机校准。如果使用其他舵机或自制外壳，可能需要调整 `animation.py` 中的 `min_angle` / `max_angle` 避免堵转。
> **MOU 引脚差异**：`CogletESP` 分支 MOU 使用 **GP19**，`camera-version` 分支 MOU 使用 **GP9**。请根据实际 PCB 版本确认。
#### 校准模式使用方法
CogNog V1.0 PCB 上有一个 **SW11（Calibration Switch）** 拨动开关，连接 RP2040 的 GPIO20。代码中 GPIO20 配置了内部上拉电阻：
```python
mode = Pin(20, Pin.IN, Pin.PULL_UP)
is_calibrating = (mode.value() == 1) # 高电平 = 校准模式
```
**SW11 逻辑：**
| SW11 状态 | GPIO20 电平 | 模式 | 表现 |
|----------|-----------|------|------|
| 断开（GPIO20 悬空） | 高（内部上拉到 1） | **校准模式** | 所有舵机归 90° 中位，LED 闪烁 |
| 接通（GPIO20 接 GND） | 低 | **正常运行模式** | 响应 ESP32 状态指令，执行动画 |
> **提示**：如果不确定 SW11 哪个位置对应哪种模式，两个位置都试一下，**LED 闪烁的那个就是校准模式**。
#### 校准与组装流程
**前提**：RP2040 已刷入 MicroPython 固件并上传 .py 文件。
```
第 1 步：进入校准模式
└→ 将 SW11 拨到校准位置（LED 闪烁）
第 2 步：通电
└→ 给 RP2040 和舵机供电
└→ 所有 9 个舵机自动转到 90° 中位（staggered startup，逐个上电避免电流冲击）
第 3 步：安装舵机臂
└→ 在 90° 中位状态下，将舵机臂安装到需要的朝向
└→ 拧紧舵机臂固定螺丝
└→ ⚠️ 关键：必须在通电校准状态下安装，否则角度对不上
第 4 步：组装机械结构
└→ 将舵机装入 3D 打印外壳
└→ 连接所有机械连杆
第 5 步：验证
└→ 将 SW11 拨回正常运行模式
└→ 观察舵机是否能正常运动，无堵转
└→ 如有堵转，调整 animation.py 中对应舵机的 min_angle / max_angle
第 6 步：连接 ESP32
└→ 接上 ESP32 UART（TX→GP5, RX→GP4）
└→ ESP32 发送状态指令，舵机开始响应 AI 对话动画
```
> **校准模式不需要断开 ESP32**：校准模式在主循环中每帧都强制覆盖舵机状态（`main.py` 第 153-155 行），即使 ESP32 发送了指令也会被忽略。
### 4.10 camera-version 的代价与限制
| 项目 | 说明 |
|------|------|
| **LCD 屏被禁用** | 摄像头占用了原 LCD 引脚，代码用 DummyDisplay 空实现替代 |
| **音频引脚全部重映射** | MIC 从 GPIO 1/2/42 移到 4/5/6，SPK 从 GPIO 39/40/41 移到 7/15/16 |
| **内存压力** | 摄像头 + PSRAM 同时运行可能偶发内存不足（作者提到 "appears to run out of memory sometimes"） |
| **摄像头画面翻转** | 已通过代码设置 `SetHMirror(true)` + `SetVFlip(true)` 修正 |
---
## 五、无摄像头版本搭建流程（CogletESP 分支）
> 如果不使用 ESP32 OV3660 摄像头，想保留 LCD 显示，使用此方案。
### 5.1 代码下载
```bash
git clone -b CogletESP https://github.com/will-cogley/CogletESP.git
git clone https://github.com/will-cogley/Coglet.git
```
### 5.2 ESP32 编译烧录
与摄像头版本相同（参见 4.5），但 menuconfig 中的板级配置可能不同，PCB **无需飞线**。
### 5.3 RP2040 烧录
MicroPython 固件刷入方式与摄像头版本相同（参见 4.6），但 **RP2040 代码两个分支不同**：
- `CogletESP` 分支有 **4 个文件**：`main.py`、`servoclass.py`、`coms.py`、`animation.py`
- `camera-version` 分支只有 **3 个文件**（无 `coms.py`，UART 通信集成在 `main.py` 中）
请使用对应分支的 RP2040 目录文件上传。
### 5.4 Grove Vision AI V2
与摄像头版本完全相同（参见 4.7），Grove Vision AI V2 的人脸追踪功能由 RP2040 端控制，与 ESP32 分支选择无关。
---
## 六、常见问题
| 问题 | 解决方案 |
|------|---------|
| Python 环境冲突 | `idf.py fullclean` 后重新编译 |
| Bootloader CMake 缓存不匹配 | `rm -rf build/bootloader build/bootloader-prefix` |
| 找不到串口设备 | 安装 CP2102/CH340 驱动，检查 USB 线是否支持数据传输 |
| menuconfig 中找不到板级配置 | 确认在正确的分支（`camera-version` 或 `CogletESP`） |
| 摄像头不工作 | 确认已完成 3 根飞线（35→14, 36→41, 37→42）并使用 `camera-version` 分支 |
| 偶发内存不足 | camera-version 已知问题，摄像头 + PSRAM 同时运行时可能出现 |
| Grove Vision AI V2 无响应 | 确认已通过 SenseCraft 部署人脸检测模型，UART 波特率 921600 |
| 舵机不动 | 检查 RP2040 是否正确上传 .py 文件（CogletESP 分支 4 个 / camera-version 分支 3 个），UART 连接是否正常 |
| 舵机堵转、发烫、齿轮刺耳声 | **使用了 360° 连续旋转舵机**，必须更换为 180° 标准舵机（详见 4.9 舵机选型说明） |
| 舵机持续朝一个方向旋转不停 | 同上，360° 舵机收到非 90° 信号会持续旋转。180° 舵机会转到目标角度后自动停住 |

# An MCP-based Chatbot
（中文 | [English](README.md) | [日本語](README_ja.md)）
## 介绍
👉 [人类：给 AI 装摄像头 vs AI：当场发现主人三天没洗头【bilibili】](https://www.bilibili.com/video/BV1bpjgzKEhd/)
👉 [手工打造你的 AI 女友，新手入门教程【bilibili】](https://www.bilibili.com/video/BV1XnmFYLEJN/)
小智 AI 聊天机器人作为一个语音交互入口，利用 Qwen / DeepSeek 等大模型的 AI 能力，通过 MCP 协议实现多端控制。
<img src="docs/mcp-based-graph.jpg" alt="通过MCP控制万物" width="320">
### 版本说明
当前 v2 版本与 v1 版本分区表不兼容，所以无法从 v1 版本通过 OTA 升级到 v2 版本。分区表说明参见 [partitions/v2/README.md](partitions/v2/README.md)。
使用 v1 版本的所有硬件，可以通过手动烧录固件来升级到 v2 版本。
v1 的稳定版本为 1.9.2，可以通过 `git checkout v1` 来切换到 v1 版本，该分支会持续维护到 2026 年 2 月。
### 已实现功能
- Wi-Fi / ML307 Cat.1 4G
- 离线语音唤醒 [ESP-SR](https://github.com/espressif/esp-sr)
- 支持两种通信协议（[Websocket](docs/websocket.md) 或 MQTT+UDP）
- 采用 OPUS 音频编解码
- 基于流式 ASR + LLM + TTS 架构的语音交互
- 声纹识别，识别当前说话人的身份 [3D Speaker](https://github.com/modelscope/3D-Speaker)
- OLED / LCD 显示屏，支持表情显示
- 电量显示与电源管理
- 支持多语言（中文、英文、日文）
- 支持 ESP32-C3、ESP32-S3、ESP32-P4 芯片平台
- 通过设备端 MCP 实现设备控制（音量、灯光、电机、GPIO 等）
- 通过云端 MCP 扩展大模型能力（智能家居控制、PC桌面操作、知识搜索、邮件收发等）
- 自定义唤醒词、字体、表情与聊天背景，支持网页端在线修改 ([自定义Assets生成器](https://github.com/78/xiaozhi-assets-generator))

# 自定义开发板指南
本指南介绍如何为小智AI语音聊天机器人项目定制一个新的开发板初始化程序。小智AI支持70多种ESP32系列开发板，每个开发板的初始化代码都放在对应的目录下。
## 重要提示
> **警告**: 对于自定义开发板，当IO配置与原有开发板不同时，切勿直接覆盖原有开发板的配置编译固件。必须创建新的开发板类型，或者通过config.json文件中的builds配置不同的name和sdkconfig宏定义来区分。使用 `python scripts/release.py [开发板目录名字]` 来编译打包固件。
>
> 如果直接覆盖原有配置，将来OTA升级时，您的自定义固件可能会被原有开发板的标准固件覆盖，导致您的设备无法正常工作。每个开发板有唯一的标识和对应的固件升级通道，保持开发板标识的唯一性非常重要。
## 目录结构
每个开发板的目录结构通常包含以下文件：
- `xxx_board.cc` - 主要的板级初始化代码，实现了板子相关的初始化和功能
- `config.h` - 板级配置文件，定义了硬件管脚映射和其他配置项
- `config.json` - 编译配置，指定目标芯片和特殊的编译选项
- `README.md` - 开发板相关的说明文档
## 定制开发板步骤
### 1. 创建新的开发板目录
首先在`boards/`目录下创建一个新的目录，命名方式应使用 `[品牌名]-[开发板类型]` 的形式，例如 `m5stack-tab5`：
```bash
mkdir main/boards/my-custom-board
```
### 2. 创建配置文件
#### config.h
在`config.h`中定义所有的硬件配置，包括:
- 音频采样率和I2S引脚配置
- 音频编解码芯片地址和I2C引脚配置
- 按钮和LED引脚配置
- 显示屏参数和引脚配置
参考示例（来自lichuang-c3-dev）：
```c
#ifndef _BOARD_CONFIG_H_
#define _BOARD_CONFIG_H_
#include <driver/gpio.h>
// 音频配置
#define AUDIO_INPUT_SAMPLE_RATE 24000
#define AUDIO_OUTPUT_SAMPLE_RATE 24000
#define AUDIO_I2S_GPIO_MCLK GPIO_NUM_10
#define AUDIO_I2S_GPIO_WS GPIO_NUM_12
#define AUDIO_I2S_GPIO_BCLK GPIO_NUM_8
#define AUDIO_I2S_GPIO_DIN GPIO_NUM_7
#define AUDIO_I2S_GPIO_DOUT GPIO_NUM_11
#define AUDIO_CODEC_PA_PIN GPIO_NUM_13
#define AUDIO_CODEC_I2C_SDA_PIN GPIO_NUM_0
#define AUDIO_CODEC_I2C_SCL_PIN GPIO_NUM_1
#define AUDIO_CODEC_ES8311_ADDR ES8311_CODEC_DEFAULT_ADDR
// 按钮配置
#define BOOT_BUTTON_GPIO GPIO_NUM_9
// 显示屏配置
#define DISPLAY_SPI_SCK_PIN GPIO_NUM_3
#define DISPLAY_SPI_MOSI_PIN GPIO_NUM_5
#define DISPLAY_DC_PIN GPIO_NUM_6
#define DISPLAY_SPI_CS_PIN GPIO_NUM_4
#define DISPLAY_WIDTH 320
#define DISPLAY_HEIGHT 240
#define DISPLAY_MIRROR_X true
#define DISPLAY_MIRROR_Y false
#define DISPLAY_SWAP_XY true
#define DISPLAY_OFFSET_X 0
#define DISPLAY_OFFSET_Y 0
#define DISPLAY_BACKLIGHT_PIN GPIO_NUM_2
#define DISPLAY_BACKLIGHT_OUTPUT_INVERT true
#endif // _BOARD_CONFIG_H_
```
#### config.json
在`config.json`中定义编译配置，这个文件用于 `scripts/release.py` 脚本自动化编译：
```json
{
"target": "esp32s3", // 目标芯片型号: esp32, esp32s3, esp32c3, esp32c6, esp32p4等
"builds": [
{
"name": "my-custom-board", // 开发板名称，用于生成固件包
"sdkconfig_append": [
// 特别 Flash 大小配置
"CONFIG_ESPTOOLPY_FLASHSIZE_8MB=y",
// 特别分区表配置
"CONFIG_PARTITION_TABLE_CUSTOM_FILENAME=\"partitions/v2/8m.csv\""
]
}
]
}
```
**配置项说明：**
- `target`: 目标芯片型号，必须与硬件匹配
- `name`: 编译输出的固件包名称，建议与目录名一致
- `sdkconfig_append`: 额外的 sdkconfig 配置项数组，会追加到默认配置中
**常用的 sdkconfig_append 配置：**
```json
// Flash 大小
"CONFIG_ESPTOOLPY_FLASHSIZE_4MB=y" // 4MB Flash
"CONFIG_ESPTOOLPY_FLASHSIZE_8MB=y" // 8MB Flash
"CONFIG_ESPTOOLPY_FLASHSIZE_16MB=y" // 16MB Flash
// 分区表
"CONFIG_PARTITION_TABLE_CUSTOM_FILENAME=\"partitions/v2/4m.csv\"" // 4MB 分区表
"CONFIG_PARTITION_TABLE_CUSTOM_FILENAME=\"partitions/v2/8m.csv\"" // 8MB 分区表
"CONFIG_PARTITION_TABLE_CUSTOM_FILENAME=\"partitions/v2/16m.csv\"" // 16MB 分区表
// 语言配置
"CONFIG_LANGUAGE_EN_US=y" // 英语
"CONFIG_LANGUAGE_ZH_CN=y" // 简体中文
// 唤醒词配置
"CONFIG_USE_DEVICE_AEC=y" // 启用设备端 AEC
"CONFIG_WAKE_WORD_DISABLED=y" // 禁用唤醒词
```
### 3. 编写板级初始化代码
创建一个`my_custom_board.cc`文件，实现开发板的所有初始化逻辑。
一个基本的开发板类定义包含以下几个部分：
1. **类定义**：继承自`WifiBoard`或`Ml307Board`
2. **初始化函数**：包括I2C、显示屏、按钮、IoT等组件的初始化
3. **虚函数重写**：如`GetAudioCodec()`、`GetDisplay()`、`GetBacklight()`等
4. **注册开发板**：使用`DECLARE_BOARD`宏注册开发板
```cpp
#include "wifi_board.h"
#include "codecs/es8311_audio_codec.h"
#include "display/lcd_display.h"
#include "application.h"
#include "button.h"
#include "config.h"
#include "mcp_server.h"
#include <esp_log.h>
#include <driver/i2c_master.h>
#include <driver/spi_common.h>
#define TAG "MyCustomBoard"
class MyCustomBoard : public WifiBoard {
private:
i2c_master_bus_handle_t codec_i2c_bus_;
Button boot_button_;
LcdDisplay* display_;
// I2C初始化
void InitializeI2c() {
i2c_master_bus_config_t i2c_bus_cfg = {
.i2c_port = I2C_NUM_0,
.sda_io_num = AUDIO_CODEC_I2C_SDA_PIN,
.scl_io_num = AUDIO_CODEC_I2C_SCL_PIN,
.clk_source = I2C_CLK_SRC_DEFAULT,
.glitch_ignore_cnt = 7,
.intr_priority = 0,
.trans_queue_depth = 0,
.flags = {
.enable_internal_pullup = 1,
},
};
ESP_ERROR_CHECK(i2c_new_master_bus(&i2c_bus_cfg, &codec_i2c_bus_));
}
// SPI初始化（用于显示屏）
void InitializeSpi() {
spi_bus_config_t buscfg = {};
buscfg.mosi_io_num = DISPLAY_SPI_MOSI_PIN;
buscfg.miso_io_num = GPIO_NUM_NC;
buscfg.sclk_io_num = DISPLAY_SPI_SCK_PIN;
buscfg.quadwp_io_num = GPIO_NUM_NC;
buscfg.quadhd_io_num = GPIO_NUM_NC;
buscfg.max_transfer_sz = DISPLAY_WIDTH * DISPLAY_HEIGHT * sizeof(uint16_t);
ESP_ERROR_CHECK(spi_bus_initialize(SPI2_HOST, &buscfg, SPI_DMA_CH_AUTO));
}
// 按钮初始化
void InitializeButtons() {
boot_button_.OnClick([this]() {
auto& app = Application::GetInstance();
if (app.GetDeviceState() == kDeviceStateStarting && !WifiStation::GetInstance().IsConnected()) {
ResetWifiConfiguration();
}
app.ToggleChatState();
});
}
// 显示屏初始化（以ST7789为例）
void InitializeDisplay() {
esp_lcd_panel_io_handle_t panel_io = nullptr;
esp_lcd_panel_handle_t panel = nullptr;
esp_lcd_panel_io_spi_config_t io_config = {};
io_config.cs_gpio_num = DISPLAY_SPI_CS_PIN;
io_config.dc_gpio_num = DISPLAY_DC_PIN;
io_config.spi_mode = 2;
io_config.pclk_hz = 80 * 1000 * 1000;
io_config.trans_queue_depth = 10;
io_config.lcd_cmd_bits = 8;
io_config.lcd_param_bits = 8;
ESP_ERROR_CHECK(esp_lcd_new_panel_io_spi(SPI2_HOST, &io_config, &panel_io));
esp_lcd_panel_dev_config_t panel_config = {};
panel_config.reset_gpio_num = GPIO_NUM_NC;
panel_config.rgb_ele_order = LCD_RGB_ELEMENT_ORDER_RGB;
panel_config.bits_per_pixel = 16;
ESP_ERROR_CHECK(esp_lcd_new_panel_st7789(panel_io, &panel_config, &panel));
esp_lcd_panel_reset(panel);
esp_lcd_panel_init(panel);
esp_lcd_panel_invert_color(panel, true);
esp_lcd_panel_swap_xy(panel, DISPLAY_SWAP_XY);
esp_lcd_panel_mirror(panel, DISPLAY_MIRROR_X, DISPLAY_MIRROR_Y);
// 创建显示屏对象
display_ = new SpiLcdDisplay(panel_io, panel,
DISPLAY_WIDTH, DISPLAY_HEIGHT,
DISPLAY_OFFSET_X, DISPLAY_OFFSET_Y,
DISPLAY_MIRROR_X, DISPLAY_MIRROR_Y, DISPLAY_SWAP_XY);
}
// MCP Tools 初始化
void InitializeTools() {
// 参考 MCP 文档
}
public:
// 构造函数
MyCustomBoard() : boot_button_(BOOT_BUTTON_GPIO) {
InitializeI2c();
InitializeSpi();
InitializeDisplay();
InitializeButtons();
InitializeTools();
GetBacklight()->SetBrightness(100);
}
// 获取音频编解码器
virtual AudioCodec* GetAudioCodec() override {
static Es8311AudioCodec audio_codec(
codec_i2c_bus_,
I2C_NUM_0,
AUDIO_INPUT_SAMPLE_RATE,
AUDIO_OUTPUT_SAMPLE_RATE,
AUDIO_I2S_GPIO_MCLK,
AUDIO_I2S_GPIO_BCLK,
AUDIO_I2S_GPIO_WS,
AUDIO_I2S_GPIO_DOUT,
AUDIO_I2S_GPIO_DIN,
AUDIO_CODEC_PA_PIN,
AUDIO_CODEC_ES8311_ADDR);
return &audio_codec;
}
// 获取显示屏
virtual Display* GetDisplay() override {
return display_;
}
// 获取背光控制
virtual Backlight* GetBacklight() override {
static PwmBacklight backlight(DISPLAY_BACKLIGHT_PIN, DISPLAY_BACKLIGHT_OUTPUT_INVERT);
return &backlight;
}
};
// 注册开发板
DECLARE_BOARD(MyCustomBoard);
```
### 4. 添加构建系统配置
#### 在 Kconfig.projbuild 中添加开发板选项
打开 `main/Kconfig.projbuild` 文件，在 `choice BOARD_TYPE` 部分添加新的开发板配置项：
```kconfig
choice BOARD_TYPE
prompt "Board Type"
default BOARD_TYPE_BREAD_COMPACT_WIFI
help
Board type. 开发板类型
# ... 其他开发板选项 ...
config BOARD_TYPE_MY_CUSTOM_BOARD
bool "My Custom Board (我的自定义开发板)"
depends on IDF_TARGET_ESP32S3 # 根据你的目标芯片修改
endchoice
```
**注意事项：**
- `BOARD_TYPE_MY_CUSTOM_BOARD` 是配置项名称，需要全大写，使用下划线分隔
- `depends on` 指定了目标芯片类型（如 `IDF_TARGET_ESP32S3`、`IDF_TARGET_ESP32C3` 等）
- 描述文字可以使用中英文
#### 在 CMakeLists.txt 中添加开发板配置
打开 `main/CMakeLists.txt` 文件，在开发板类型判断部分添加新的配置：
```cmake
# 在 elseif 链中添加你的开发板配置
elseif(CONFIG_BOARD_TYPE_MY_CUSTOM_BOARD)
set(BOARD_TYPE "my-custom-board") # 与目录名一致
set(BUILTIN_TEXT_FONT font_puhui_basic_20_4) # 根据屏幕大小选择合适的字体
set(BUILTIN_ICON_FONT font_awesome_20_4)
set(DEFAULT_EMOJI_COLLECTION twemoji_64) # 可选，如果需要表情显示
endif()
```
**字体和表情配置说明：**
根据屏幕分辨率选择合适的字体大小：
- 小屏幕（128x64 OLED）：`font_puhui_basic_14_1` / `font_awesome_14_1`
- 中小屏幕（240x240）：`font_puhui_basic_16_4` / `font_awesome_16_4`
- 中等屏幕（240x320）：`font_puhui_basic_20_4` / `font_awesome_20_4`
- 大屏幕（480x320+）：`font_puhui_basic_30_4` / `font_awesome_30_4`
表情集合选项：
- `twemoji_32` - 32x32 像素表情（小屏幕）
- `twemoji_64` - 64x64 像素表情（大屏幕）
### 5. 配置和编译
#### 方法一：使用 idf.py 手动配置
1. **设置目标芯片**（首次配置或更换芯片时）：
```bash
# 对于 ESP32-S3
idf.py set-target esp32s3
# 对于 ESP32-C3
idf.py set-target esp32c3
# 对于 ESP32
idf.py set-target esp32
```
2. **清理旧配置**：
```bash
idf.py fullclean
```
3. **进入配置菜单**：
```bash
idf.py menuconfig
```
在菜单中导航到：`Xiaozhi Assistant` -> `Board Type`，选择你的自定义开发板。
4. **编译和烧录**：
```bash
idf.py build
idf.py flash monitor
```
#### 方法二：使用 release.py 脚本（推荐）
如果你的开发板目录下有 `config.json` 文件，可以使用此脚本自动完成配置和编译：
```bash
python scripts/release.py my-custom-board
```
此脚本会自动：
- 读取 `config.json` 中的 `target` 配置并设置目标芯片
- 应用 `sdkconfig_append` 中的编译选项
- 完成编译并打包固件
### 6. 创建README.md
在README.md中说明开发板的特性、硬件要求、编译和烧录步骤：
## 常见开发板组件
### 1. 显示屏
项目支持多种显示屏驱动，包括:
- ST7789 (SPI)
- ILI9341 (SPI)
- SH8601 (QSPI)
- 等...
### 2. 音频编解码器
支持的编解码器包括:
- ES8311 (常用)
- ES7210 (麦克风阵列)
- AW88298 (功放)
- 等...
### 3. 电源管理
一些开发板使用电源管理芯片:
- AXP2101
- 其他可用的PMIC
### 4. MCP设备控制
可以添加各种MCP工具，让AI能够使用:
- Speaker (扬声器控制)
- Screen (屏幕亮度调节)
- Battery (电池电量读取)
- Light (灯光控制)
- 等...
## 开发板类继承关系
- `Board` - 基础板级类
- `WifiBoard` - Wi-Fi连接的开发板
- `Ml307Board` - 使用4G模块的开发板
- `DualNetworkBoard` - 支持Wi-Fi与4G网络切换的开发板
## 开发技巧
1. **参考相似的开发板**：如果您的新开发板与现有开发板有相似之处，可以参考现有实现
2. **分步调试**：先实现基础功能（如显示），再添加更复杂的功能（如音频）
3. **管脚映射**：确保在config.h中正确配置所有管脚映射
4. **检查硬件兼容性**：确认所有芯片和驱动程序的兼容性
## 可能遇到的问题
1. **显示屏不正常**：检查SPI配置、镜像设置和颜色反转设置
2. **音频无输出**：检查I2S配置、PA使能引脚和编解码器地址
3. **无法连接网络**：检查Wi-Fi凭据和网络配置
4. **无法与服务器通信**：检查MQTT或WebSocket配置

# MCP (Model Context Protocol) 交互流程
NOTICE: AI 辅助生成, 在实现后台服务时, 请参照代码确认细节!!
本项目中的 MCP 协议用于后台 API（MCP 客户端）与 ESP32 设备（MCP 服务器）之间的通信，以便后台能够发现和调用设备提供的功能（工具）。
## 协议格式
根据代码 (`main/protocols/protocol.cc`, `main/mcp_server.cc`)，MCP 消息是封装在基础通信协议（如 WebSocket 或 MQTT）的消息体中的。其内部结构遵循 [JSON-RPC 2.0](https://www.jsonrpc.org/specification) 规范。
整体消息结构示例：
```json
{
"session_id": "...", // 会话 ID
"type": "mcp", // 消息类型，固定为 "mcp"
"payload": { // JSON-RPC 2.0 负载
"jsonrpc": "2.0",
"method": "...", // 方法名 (如 "initialize", "tools/list", "tools/call")
"params": { ... }, // 方法参数 (对于 request)
"id": ..., // 请求 ID (对于 request 和 response)
"result": { ... }, // 方法执行结果 (对于 success response)
"error": { ... } // 错误信息 (对于 error response)
}
}
```
其中，`payload` 部分是标准的 JSON-RPC 2.0 消息：
- `jsonrpc`: 固定的字符串 "2.0"。
- `method`: 要调用的方法名称 (对于 Request)。
- `params`: 方法的参数，一个结构化值，通常为对象 (对于 Request)。
- `id`: 请求的标识符，客户端发送请求时提供，服务器响应时原样返回。用于匹配请求和响应。
- `result`: 方法成功执行时的结果 (对于 Success Response)。
- `error`: 方法执行失败时的错误信息 (对于 Error Response)。
## 交互流程及发送时机
MCP 的交互主要围绕客户端（后台 API）发现和调用设备上的“工具”（Tool）进行。
1. **连接建立与能力通告**
- **时机：** 设备启动并成功连接到后台 API 后。
- **发送方：** 设备。
- **消息：** 设备发送基础协议的 "hello" 消息给后台 API，消息中包含设备支持的能力列表，例如通过支持 MCP 协议 (`"mcp": true`)。
- **示例 (非 MCP 负载，而是基础协议消息):**
```json
{
"type": "hello",
"version": ...,
"features": {
"mcp": true,
...
},
"transport": "websocket", // 或 "mqtt"
"audio_params": { ... },
"session_id": "..." // 设备收到服务器hello后可能设置
}
```
2. **初始化 MCP 会话**
- **时机：** 后台 API 收到设备 "hello" 消息，确认设备支持 MCP 后，通常作为 MCP 会话的第一个请求发送。
- **发送方：** 后台 API (客户端)。
- **方法：** `initialize`
- **消息 (MCP payload):**
```json
{
"jsonrpc": "2.0",
"method": "initialize",
"params": {
"capabilities": {
// 客户端能力，可选
// 摄像头视觉相关
"vision": {
"url": "...", //摄像头: 图片处理地址(必须是http地址, 不是websocket地址)
"token": "..." // url token
}
// ... 其他客户端能力
}
},
"id": 1 // 请求 ID
}
```
- **设备响应时机：** 设备收到 `initialize` 请求并处理后。
- **设备响应消息 (MCP payload):**
```json
{
"jsonrpc": "2.0",
"id": 1, // 匹配请求 ID
"result": {
"protocolVersion": "2024-11-05",
"capabilities": {
"tools": {} // 这里的 tools 似乎不列出详细信息，需要 tools/list
},
"serverInfo": {
"name": "...", // 设备名称 (BOARD_NAME)
"version": "..." // 设备固件版本
}
}
}
```
3. **发现设备工具列表**
- **时机：** 后台 API 需要获取设备当前支持的具体功能（工具）列表及其调用方式时。
- **发送方：** 后台 API (客户端)。
- **方法：** `tools/list`
- **消息 (MCP payload):**
```json
{
"jsonrpc": "2.0",
"method": "tools/list",
"params": {
"cursor": "" // 用于分页，首次请求为空字符串
},
"id": 2 // 请求 ID
}
```
- **设备响应时机：** 设备收到 `tools/list` 请求并生成工具列表后。
- **设备响应消息 (MCP payload):**
```json
{
"jsonrpc": "2.0",
"id": 2, // 匹配请求 ID
"result": {
"tools": [ // 工具对象列表
{
"name": "self.get_device_status",
"description": "...",
"inputSchema": { ... } // 参数 schema
},
{
"name": "self.audio_speaker.set_volume",
"description": "...",
"inputSchema": { ... } // 参数 schema
}
// ... 更多工具
],
"nextCursor": "..." // 如果列表很大需要分页，这里会包含下一个请求的 cursor 值
}
}
```
- **分页处理：** 如果 `nextCursor` 字段非空，客户端需要再次发送 `tools/list` 请求，并在 `params` 中带上这个 `cursor` 值以获取下一页工具。
4. **调用设备工具**
- **时机：** 后台 API 需要执行设备上的某个具体功能时。
- **发送方：** 后台 API (客户端)。
- **方法：** `tools/call`
- **消息 (MCP payload):**
```json
{
"jsonrpc": "2.0",
"method": "tools/call",
"params": {
"name": "self.audio_speaker.set_volume", // 要调用的工具名称
"arguments": {
// 工具参数，对象格式
"volume": 50 // 参数名及其值
}
},
"id": 3 // 请求 ID
}
```
- **设备响应时机：** 设备收到 `tools/call` 请求，执行相应的工具函数后。
- **设备成功响应消息 (MCP payload):**
```json
{
"jsonrpc": "2.0",
"id": 3, // 匹配请求 ID
"result": {
"content": [
// 工具执行结果内容
{ "type": "text", "text": "true" } // 示例：set_volume 返回 bool
],
"isError": false // 表示成功
}
}
```
- **设备失败响应消息 (MCP payload):**
```json
{
"jsonrpc": "2.0",
"id": 3, // 匹配请求 ID
"error": {
"code": -32601, // JSON-RPC 错误码，例如 Method not found (-32601)
"message": "Unknown tool: self.non_existent_tool" // 错误描述
}
}
```
5. **设备主动发送消息 (Notifications)**
- **时机：** 设备内部发生需要通知后台 API 的事件时（例如，状态变化，虽然代码示例中没有明确的工具发送此类消息，但 `Application::SendMcpMessage` 的存在暗示了设备可能主动发送 MCP 消息）。
- **发送方：** 设备 (服务器)。
- **方法：** 可能是以 `notifications/` 开头的方法名，或者其他自定义方法。
- **消息 (MCP payload):** 遵循 JSON-RPC Notification 格式，没有 `id` 字段。
```json
{
"jsonrpc": "2.0",
"method": "notifications/state_changed", // 示例方法名
"params": {
"newState": "idle",
"oldState": "connecting"
}
// 没有 id 字段
}
```
- **后台 API 处理：** 接收到 Notification 后，后台 API 进行相应的处理，但不回复。

# MCP 协议物联网控制用法说明
> 本文档介绍如何基于 MCP 协议实现 ESP32 设备的物联网控制。详细协议流程请参考 [`mcp-protocol.md`](./mcp-protocol.md)。
## 简介
MCP（Model Context Protocol）是新一代推荐用于物联网控制的协议，通过标准 JSON-RPC 2.0 格式在后台与设备间发现和调用"工具"（Tool），实现灵活的设备控制。
## 典型使用流程
1. 设备启动后通过基础协议（如 WebSocket/MQTT）与后台建立连接。
2. 后台通过 MCP 协议的 `initialize` 方法初始化会话。
3. 后台通过 `tools/list` 获取设备支持的所有工具（功能）及参数说明。
4. 后台通过 `tools/call` 调用具体工具，实现对设备的控制。
详细协议格式与交互请见 [`mcp-protocol.md`](./mcp-protocol.md)。
## 设备端工具注册方法说明
设备通过 `McpServer::AddTool` 方法注册可被后台调用的"工具"。其常用函数签名如下：
```cpp
void AddTool(
const std::string& name, // 工具名称，建议唯一且有层次感，如 self.dog.forward
const std::string& description, // 工具描述，简明说明功能，便于大模型理解
const PropertyList& properties, // 输入参数列表（可为空），支持类型：布尔、整数、字符串
std::function<ReturnValue(const PropertyList&)> callback // 工具被调用时的回调实现
);
```
- name：工具唯一标识，建议用"模块.功能"命名风格。
- description：自然语言描述，便于 AI/用户理解。
- properties：参数列表，支持类型有布尔、整数、字符串，可指定范围和默认值。
- callback：收到调用请求时的实际执行逻辑，返回值可为 bool/int/string。
## 典型注册示例（以 ESP-Hi 为例）
```cpp
void InitializeTools() {
auto& mcp_server = McpServer::GetInstance();
// 例1：无参数，控制机器人前进
mcp_server.AddTool("self.dog.forward", "机器人向前移动", PropertyList(), [this](const PropertyList&) -> ReturnValue {
servo_dog_ctrl_send(DOG_STATE_FORWARD, NULL);
return true;
});
// 例2：带参数，设置灯光 RGB 颜色
mcp_server.AddTool("self.light.set_rgb", "设置RGB颜色", PropertyList({
Property("r", kPropertyTypeInteger, 0, 255),
Property("g", kPropertyTypeInteger, 0, 255),
Property("b", kPropertyTypeInteger, 0, 255)
}), [this](const PropertyList& properties) -> ReturnValue {
int r = properties["r"].value<int>();
int g = properties["g"].value<int>();
int b = properties["b"].value<int>();
led_on_ = true;
SetLedColor(r, g, b);
return true;
});
}
```
## 常见工具调用 JSON-RPC 示例
### 1. 获取工具列表
```json
{
"jsonrpc": "2.0",
"method": "tools/list",
"params": { "cursor": "" },
"id": 1
}
```
### 2. 控制底盘前进
```json
{
"jsonrpc": "2.0",
"method": "tools/call",
"params": {
"name": "self.chassis.go_forward",
"arguments": {}
},
"id": 2
}
```
### 3. 切换灯光模式
```json
{
"jsonrpc": "2.0",
"method": "tools/call",
"params": {
"name": "self.chassis.switch_light_mode",
"arguments": { "light_mode": 3 }
},
"id": 3
}
```
### 4. 摄像头翻转
```json
{
"jsonrpc": "2.0",
"method": "tools/call",
"params": {
"name": "self.camera.set_camera_flipped",
"arguments": {}
},
"id": 4
}
```
## 备注
- 工具名称、参数及返回值请以设备端 `AddTool` 注册为准。
- 推荐所有新项目统一采用 MCP 协议进行物联网控制。
- 详细协议与进阶用法请查阅 [`mcp-protocol.md`](./mcp-protocol.md)。

以下是一份基于代码实现整理的 WebSocket 通信协议文档，概述设备端与服务器之间如何通过 WebSocket 进行交互。
该文档仅基于所提供的代码推断，实际部署时可能需要结合服务器端实现进行进一步确认或补充。
---
## 1. 总体流程概览
1. **设备端初始化**
- 设备上电、初始化 `Application`：
- 初始化音频编解码器、显示屏、LED 等
- 连接网络
- 创建并初始化实现 `Protocol` 接口的 WebSocket 协议实例（`WebsocketProtocol`）
- 进入主循环等待事件（音频输入、音频输出、调度任务等）。
2. **建立 WebSocket 连接**
- 当设备需要开始语音会话时（例如用户唤醒、手动按键触发等），调用 `OpenAudioChannel()`：
- 根据配置获取 WebSocket URL
- 设置若干请求头（`Authorization`, `Protocol-Version`, `Device-Id`, `Client-Id`）
- 调用 `Connect()` 与服务器建立 WebSocket 连接
3. **设备端发送 "hello" 消息**
- 连接成功后，设备会发送一条 JSON 消息，示例结构如下：
```json
{
"type": "hello",
"version": 1,
"features": {
"mcp": true
},
"transport": "websocket",
"audio_params": {
"format": "opus",
"sample_rate": 16000,
"channels": 1,
"frame_duration": 60
}
}
```
- 其中 `features` 字段为可选，内容根据设备编译配置自动生成。例如：`"mcp": true` 表示支持 MCP 协议。
- `frame_duration` 的值对应 `OPUS_FRAME_DURATION_MS`（例如 60ms）。
4. **服务器回复 "hello"**
- 设备等待服务器返回一条包含 `"type": "hello"` 的 JSON 消息，并检查 `"transport": "websocket"` 是否匹配。
- 服务器可选下发 `session_id` 字段，设备端收到后会自动记录。
- 示例：
```json
{
"type": "hello",
"transport": "websocket",
"session_id": "xxx",
"audio_params": {
"format": "opus",
"sample_rate": 24000,
"channels": 1,
"frame_duration": 60
}
}
```
- 如果匹配，则认为服务器已就绪，标记音频通道打开成功。
- 如果在超时时间（默认 10 秒）内未收到正确回复，认为连接失败并触发网络错误回调。
5. **后续消息交互**
- 设备端和服务器端之间可发送两种主要类型的数据：
1. **二进制音频数据**（Opus 编码）
2. **文本 JSON 消息**（用于传输聊天状态、TTS/STT 事件、MCP 协议消息等）
- 在代码里，接收回调主要分为：
- `OnData(...)`:
- 当 `binary` 为 `true` 时，认为是音频帧；设备会将其当作 Opus 数据进行解码。
- 当 `binary` 为 `false` 时，认为是 JSON 文本，需要在设备端用 cJSON 进行解析并做相应业务逻辑处理（如聊天、TTS、MCP 协议消息等）。
- 当服务器或网络出现断连，回调 `OnDisconnected()` 被触发：
- 设备会调用 `on_audio_channel_closed_()`，并最终回到空闲状态。
6. **关闭 WebSocket 连接**
- 设备在需要结束语音会话时，会调用 `CloseAudioChannel()` 主动断开连接，并回到空闲状态。
- 或者如果服务器端主动断开，也会引发同样的回调流程。
---
## 2. 通用请求头
在建立 WebSocket 连接时，代码示例中设置了以下请求头：
- `Authorization`: 用于存放访问令牌，形如 `"Bearer <token>"`
- `Protocol-Version`: 协议版本号，与 hello 消息体内的 `version` 字段保持一致
- `Device-Id`: 设备物理网卡 MAC 地址
- `Client-Id`: 软件生成的 UUID（擦除 NVS 或重新烧录完整固件会重置）
这些头会随着 WebSocket 握手一起发送到服务器，服务器可根据需求进行校验、认证等。
---
## 3. 二进制协议版本
设备支持多种二进制协议版本，通过配置中的 `version` 字段指定：
### 3.1 版本1（默认）
直接发送 Opus 音频数据，无额外元数据。Websocket 协议会区分 text 与 binary。
### 3.2 版本2
使用 `BinaryProtocol2` 结构：
```c
struct BinaryProtocol2 {
uint16_t version; // 协议版本
uint16_t type; // 消息类型 (0: OPUS, 1: JSON)
uint32_t reserved; // 保留字段
uint32_t timestamp; // 时间戳（毫秒，用于服务器端AEC）
uint32_t payload_size; // 负载大小（字节）
uint8_t payload[]; // 负载数据
} __attribute__((packed));
```
### 3.3 版本3
使用 `BinaryProtocol3` 结构：
```c
struct BinaryProtocol3 {
uint8_t type; // 消息类型
uint8_t reserved; // 保留字段
uint16_t payload_size; // 负载大小
uint8_t payload[]; // 负载数据
} __attribute__((packed));
```
---
## 4. JSON 消息结构
WebSocket 文本帧以 JSON 方式传输，以下为常见的 `"type"` 字段及其对应业务逻辑。若消息里包含未列出的字段，可能为可选或特定实现细节。
### 4.1 设备端→服务器
1. **Hello**
- 连接成功后，由设备端发送，告知服务器基本参数。
- 例：
```json
{
"type": "hello",
"version": 1,
"features": {
"mcp": true
},
"transport": "websocket",
"audio_params": {
"format": "opus",
"sample_rate": 16000,
"channels": 1,
"frame_duration": 60
}
}
```
2. **Listen**
- 表示设备端开始或停止录音监听。
- 常见字段：
- `"session_id"`：会话标识
- `"type": "listen"`
- `"state"`：`"start"`, `"stop"`, `"detect"`（唤醒检测已触发）
- `"mode"`：`"auto"`, `"manual"` 或 `"realtime"`，表示识别模式。
- 例：开始监听
```json
{
"session_id": "xxx",
"type": "listen",
"state": "start",
"mode": "manual"
}
```
3. **Abort**
- 终止当前说话（TTS 播放）或语音通道。
- 例：
```json
{
"session_id": "xxx",
"type": "abort",
"reason": "wake_word_detected"
}
```
- `reason` 值可为 `"wake_word_detected"` 或其他。
4. **Wake Word Detected**
- 用于设备端向服务器告知检测到唤醒词。
- 在发送该消息之前，可提前发送唤醒词的 Opus 音频数据，用于服务器进行声纹检测。
- 例：
```json
{
"session_id": "xxx",
"type": "listen",
"state": "detect",
"text": "你好小明"
}
```
5. **MCP**
- 推荐用于物联网控制的新一代协议。所有设备能力发现、工具调用等均通过 type: "mcp" 的消息进行，payload 内部为标准 JSON-RPC 2.0（详见 [MCP 协议文档](./mcp-protocol.md)）。
- **设备端到服务器发送 result 的例子：**
```json
{
"session_id": "xxx",
"type": "mcp",
"payload": {
"jsonrpc": "2.0",
"id": 1,
"result": {
"content": [
{ "type": "text", "text": "true" }
],
"isError": false
}
}
}
```
---
### 4.2 服务器→设备端
1. **Hello**
- 服务器端返回的握手确认消息。
- 必须包含 `"type": "hello"` 和 `"transport": "websocket"`。
- 可能会带有 `audio_params`，表示服务器期望的音频参数，或与设备端对齐的配置。
- 服务器可选下发 `session_id` 字段，设备端收到后会自动记录。
- 成功接收后设备端会设置事件标志，表示 WebSocket 通道就绪。
2. **STT**
- `{"session_id": "xxx", "type": "stt", "text": "..."}`
- 表示服务器端识别到了用户语音。（例如语音转文本结果）
- 设备可能将此文本显示到屏幕上，后续再进入回答等流程。
3. **LLM**
- `{"session_id": "xxx", "type": "llm", "emotion": "happy", "text": "😀"}`
- 服务器指示设备调整表情动画 / UI 表达。
4. **TTS**
- `{"session_id": "xxx", "type": "tts", "state": "start"}`：服务器准备下发 TTS 音频，设备端进入 "speaking" 播放状态。
- `{"session_id": "xxx", "type": "tts", "state": "stop"}`：表示本次 TTS 结束。
- `{"session_id": "xxx", "type": "tts", "state": "sentence_start", "text": "..."}`
- 让设备在界面上显示当前要播放或朗读的文本片段（例如用于显示给用户）。
5. **MCP**
- 服务器通过 type: "mcp" 的消息下发物联网相关的控制指令或返回调用结果，payload 结构同上。
- **服务器到设备端发送 tools/call 的例子：**
```json
{
"session_id": "xxx",
"type": "mcp",
"payload": {
"jsonrpc": "2.0",
"method": "tools/call",
"params": {
"name": "self.light.set_rgb",
"arguments": { "r": 255, "g": 0, "b": 0 }
},
"id": 1
}
}
```
6. **System**
- 系统控制命令，常用于远程升级更新。
- 例：
```json
{
"session_id": "xxx",
"type": "system",
"command": "reboot"
}
```
- 支持的命令：
- `"reboot"`：重启设备
7. **Custom**（可选）
- 自定义消息，当 `CONFIG_RECEIVE_CUSTOM_MESSAGE` 启用时支持。
- 例：
```json
{
"session_id": "xxx",
"type": "custom",
"payload": {
"message": "自定义内容"
}
}
```
8. **音频数据：二进制帧**
- 当服务器发送音频二进制帧（Opus 编码）时，设备端解码并播放。
- 若设备端正在处于 "listening" （录音）状态，收到的音频帧会被忽略或清空以防冲突。
---
## 5. 音频编解码
1. **设备端发送录音数据**
- 音频输入经过可能的回声消除、降噪或音量增益后，通过 Opus 编码打包为二进制帧发送给服务器。
- 根据协议版本，可能直接发送 Opus 数据（版本1）或使用带元数据的二进制协议（版本2/3）。
2. **设备端播放收到的音频**
- 收到服务器的二进制帧时，同样认定是 Opus 数据。
- 设备端会进行解码，然后交由音频输出接口播放。
- 如果服务器的音频采样率与设备不一致，会在解码后再进行重采样。
---
## 6. 常见状态流转
以下为常见设备端关键状态流转，与 WebSocket 消息对应：
1. **Idle** → **Connecting**
- 用户触发或唤醒后，设备调用 `OpenAudioChannel()` → 建立 WebSocket 连接 → 发送 `"type":"hello"`。
2. **Connecting** → **Listening**
- 成功建立连接后，若继续执行 `SendStartListening(...)`，则进入录音状态。此时设备会持续编码麦克风数据并发送到服务器。
3. **Listening** → **Speaking**
- 收到服务器 TTS Start 消息 (`{"type":"tts","state":"start"}`) → 停止录音并播放接收到的音频。
4. **Speaking** → **Idle**
- 服务器 TTS Stop (`{"type":"tts","state":"stop"}`) → 音频播放结束。若未继续进入自动监听，则返回 Idle；如果配置了自动循环，则再度进入 Listening。
5. **Listening** / **Speaking** → **Idle**（遇到异常或主动中断）
- 调用 `SendAbortSpeaking(...)` 或 `CloseAudioChannel()` → 中断会话 → 关闭 WebSocket → 状态回到 Idle。

```

## 7. 错误处理
1. **连接失败**
- 如果 `Connect(url)` 返回失败或在等待服务器 "hello" 消息时超时，触发 `on_network_error_()` 回调。设备会提示"无法连接到服务"或类似错误信息。
2. **服务器断开**
- 如果 WebSocket 异常断开，回调 `OnDisconnected()`：
- 设备回调 `on_audio_channel_closed_()`
- 切换到 Idle 或其他重试逻辑。
---
## 8. 其它注意事项
1. **鉴权**
- 设备通过设置 `Authorization: Bearer <token>` 提供鉴权，服务器端需验证是否有效。
- 如果令牌过期或无效，服务器可拒绝握手或在后续断开。
2. **会话控制**
- 代码中部分消息包含 `session_id`，用于区分独立的对话或操作。服务端可根据需要对不同会话做分离处理。
3. **音频负载**
- 代码里默认使用 Opus 格式，并设置 `sample_rate = 16000`，单声道。帧时长由 `OPUS_FRAME_DURATION_MS` 控制，一般为 60ms。可根据带宽或性能做适当调整。为了获得更好的音乐播放效果，服务器下行音频可能使用 24000 采样率。
4. **协议版本配置**
- 通过设置中的 `version` 字段配置二进制协议版本（1、2 或 3）
- 版本1：直接发送 Opus 数据
- 版本2：使用带时间戳的二进制协议，适用于服务器端 AEC
- 版本3：使用简化的二进制协议
5. **物联网控制推荐 MCP 协议**
- 设备与服务器之间的物联网能力发现、状态同步、控制指令等，建议全部通过 MCP 协议（type: "mcp"）实现。原有的 type: "iot" 方案已废弃。
- MCP 协议可在 WebSocket、MQTT 等多种底层协议上传输，具备更好的扩展性和标准化能力。
- 详细用法请参考 [MCP 协议文档](./mcp-protocol.md) 及 [MCP 物联网控制用法](./mcp-usage.md)。
6. **错误或异常 JSON**
- 当 JSON 中缺少必要字段，例如 `{"type": ...}`，设备端会记录错误日志（`ESP_LOGE(TAG, "Missing message type, data: %s", data);`），不会执行任何业务。
---
## 9. 消息示例
下面给出一个典型的双向消息示例（流程简化示意）：
1. **设备端 → 服务器**（握手）
```json
{
"type": "hello",
"version": 1,
"features": {
"mcp": true
},
"transport": "websocket",
"audio_params": {
"format": "opus",
"sample_rate": 16000,
"channels": 1,
"frame_duration": 60
}
}
```
2. **服务器 → 设备端**（握手应答）
```json
{
"type": "hello",
"transport": "websocket",
"session_id": "xxx",
"audio_params": {
"format": "opus",
"sample_rate": 16000
}
}
```
3. **设备端 → 服务器**（开始监听）
```json
{
"session_id": "xxx",
"type": "listen",
"state": "start",
"mode": "auto"
}
```
同时设备端开始发送二进制帧（Opus 数据）。
4. **服务器 → 设备端**（ASR 结果）
```json
{
"session_id": "xxx",
"type": "stt",
"text": "用户说的话"
}
```
5. **服务器 → 设备端**（TTS开始）
```json
{
"session_id": "xxx",
"type": "tts",
"state": "start"
}
```
接着服务器发送二进制音频帧给设备端播放。
6. **服务器 → 设备端**（TTS结束）
```json
{
"session_id": "xxx",
"type": "tts",
"state": "stop"
}
```
设备端停止播放音频，若无更多指令，则回到空闲状态。
---
## 10. 总结
本协议通过在 WebSocket 上层传输 JSON 文本与二进制音频帧，完成功能包括音频流上传、TTS 音频播放、语音识别与状态管理、MCP 指令下发等。其核心特征：
- **握手阶段**：发送 `"type":"hello"`，等待服务器返回。
- **音频通道**：采用 Opus 编码的二进制帧双向传输语音流，支持多种协议版本。
- **JSON 消息**：使用 `"type"` 为核心字段标识不同业务逻辑，包括 TTS、STT、MCP、WakeWord、System、Custom 等。
- **扩展性**：可根据实际需求在 JSON 消息中添加字段，或在 headers 里进行额外鉴权。
服务器与设备端需提前约定各类消息的字段含义、时序逻辑以及错误处理规则，方能保证通信顺畅。上述信息可作为基础文档，便于后续对接、开发或扩展。
