概述

本文介绍如何使用VScode 直接开发Arduino 程序，避免使用Arduino IDE时的没有代码提示功能，文件关系不清晰、头文件打开不方便等问题及使用Visual Stdio集成插件的庞大安装工程；同时Visual Studio Code插件PlatformIO IDE开发Arduino 跨平台无论你是用的windows，ubuntu或者mac都可以玩转。

安装Visual Studio Code PlatformIO

第一步：https://code.visualstudio.com/页面下载安装vscode.
第二步：安装完成vscode启动，扩展页面下搜索platformio即可找到,选择第一个Platformio IDE，安装即可（这里需要耐心等待一会）
第三步：安装完成，重启VS Code，左下角会多一个logo图标，点击后即可显示Platformio IDE主页

测试创建工程

选择New Project创建工程（如上图），选择相应的Board，这里使用Arduino UNO
选择Framework是Arduino，选择保存路径，等待工程完成需要一点时间（10分钟吧）
完成，打开工程文件夹，修改main.cpp

参考文档

创建新工程时中的一些建议

请稍等

第一次初始化需要Internet连接，并且可能需要一些时间（需要安装依赖的工具链，框架，SDK）。
请耐心等待，并完成初始化。

项目结构

PlatformIO项目包含3个主要项目：
lib-将项目特定的（专用）库放在此处
src-将您的源文件放在此文件夹中
platformio.ini-项目配置文件

platformio.ini

PlatformIO项目配置文件：
通用选项-开发平台，开发板，框架
构建选项-构建标志，源过滤器，额外的脚本
上传选项-自定义端口，速度和额外标志
库选项-依赖项，额外的库存储
其他说明和示例，请访问文档。

上传端口

默认情况下，PlatformIO自动检测上传端口。您可以使用platformio.ini中的upload_port选项配置自定义端口：
upload_port = COM1-特定端口
upload_port = / dev / ttyUSB *-以/ dev / ttyUSB开头的任何端口
upload_port = COM [13]-COM1或COM3。

新工程终于构建好了（15分钟）

新工程需要网络下载环境，下载好后会自动跳到下面的界面

新工程里面写程序

vscode arduino esp32频率_ci_06

编写代码时有提示！很 Nice！

#include <Arduino.h>

void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
}

void loop() {
  // put your main code here, to run repeatedly:
  Serial.println("Hello World\r\n");
  delay(500);
}
