# 🧠 AGV 标定中央大脑
**环境**: Ubuntu 22.04 + ROS 2 Humble | **语言**: C++ | **通信**: gRPC over Wi-Fi 6
> 标定车间的"发令大脑",通过局域网跨平台遥控 Windows 车端执行动作并拉取遥测数据。
---
## 📋 目录
1. [系统依赖安装](#1-系统依赖一键安装)
2. [VS Code 插件配置](#2-vs-code-核心插件配置)
3. [解决 IntelliSense 报错](#3-解决-vs-code-红色波浪线)
4. [编译与运行](#4-编译与运行)
---
## 1. 系统依赖一键安装
在 Ubuntu 22.04 终端执行以下命令:
```bash
sudo apt update
sudo apt install -y build-essential cmake pkg-config gdb
sudo apt install -y protobuf-compiler-grpc libgrpc++-dev libprotobuf-dev protobuf-compiler
```
> ⚠️ **警告**: 严禁自行去 GitHub 源码编译 gRPC,直接使用 Ubuntu 官方 APT 源即可,避免浪费时间与报错。
---
## 2. VS Code 核心插件配置
打开 VS Code → 扩展商店 (Extensions)**必须安装**以下 4 个插件:
| 插件名称 | 开发者 | 用途 |
|---------|--------|------|
| **C/C++** | Microsoft | 代码补全与 GDB 调试 |
| **CMake Tools** | Microsoft | 底部快速构建状态栏 |
| **ROS** | Microsoft | 自动识别 `colcon` 工作空间 |
| **vscode-proto3** | zxh404 | `.proto` 文件语法高亮 |
---
## 3. 解决 VS Code 红色波浪线 (IntelliSense 报错)
**问题原因**: gRPC 生成的 `.pb.h` 文件在 `colcon build` 阶段动态生成于 `build/` 目录,VS Code 初始无法识别。
**修复步骤**:
1.`Ctrl+Shift+P` → 输入 `C/C++: Edit Configurations (JSON)`
2. 确保 `c_cpp_properties.json` 包含以下配置:
```json
{
"configurations": [
{
"name": "ROS2",
"includePath": [
"${workspaceFolder}/**",
"/opt/ros/humble/include/**",
"${workspaceFolder}/build/agv_calib_brain/grpc_gen/**"
],
"compilerPath": "/usr/bin/gcc",
"cStandard": "c17",
"cppStandard": "c++17",
"intelliSenseMode": "linux-gcc-x64"
}
]
}
```
> 💡 **提示**: `grpc_gen` 是 CMakeLists 中配置的自动生成源码路径,请根据实际情况微调。
---
## 4. 编译与运行 (CMake 自动化)
> ✨ **无需手动执行 `protoc`** —— CMakeLists.txt 已配置自动化脚本,编译时自动生成 C++ 网络源码。
### 4.1 编译
```bash
# 回到工作空间根目录(如 ~/agv_ws)
source /opt/ros/humble/setup.bash
colcon build --packages-select agv_calib_brain --symlink-install
```
### 4.2 运行
```bash
source install/setup.bash
ros2 run agv_calib_brain brain_node
