第1篇:Arduino与ESP32开发板的安装方法
第2篇:ESP32 helloword第一个程序示范点亮板载LED
第3篇:vscode搭建esp32 arduino开发环境
1.配置默认安装路径，安装到D盘。
打开环境变量，点击新建
输入变量名PLATFORMIO_CORE_DIR与路径：D:\PLATFORMIO_CORE 
d盘创建PLATFORMIO_CORE目录和目录：D:\PLATFORMIO_project
安装python3.8，参考方法

https://www.cnblogs.com/txwtech/p/17659393.html
安装vscode ,参考第3篇第1点的方法
第3篇:vscode搭建esp32 arduino开发环境
打开vscode,点击扩展，输入platformio,点击安装
安装完成后，点击蚂蚁头像图标，
自动安装PLATFORMIO_CORE，5-10分钟安装完毕
2. 重启vscode
3.配置安装包源路径
D:\PLATFORMIO_CORE\penv\pip.conf，内容替换如下链接
[global]
index-url = https://mirrors.aliyun.com/pypi/simple/
[install]
trusted-host = mirrors.aliyun.com
3.添加path环境变量
;D:\PLATFORMIO_CORE\penv\Scripts ，添加到path里面
4.复制括号里面的内容，包括分号(;D:\PLATFORMIO_CORE\penv\Scripts)
5.platformio IDE修改创建工程的默认目录
https://www.cnblogs.com/txwtech/p/17651682.html
输入：
pio settings set projects_dir D:\PLATFORMIO_project并回车
输入pio system info可查询当前的目录：
6.下载esp32框架
点击open,platform
点击frameworks,选择Espressif 32 
点击install
等待5-10分钟，安装完毕。退出vsocode,再次打开vscode,可查看已经安装
7.新建项目
创建项目慢，请参考：

Blink
Turns an LED on for one second, then off for one second, repeatedly.
Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
the correct LED pin independent of which board is used.
If you want to know what pin the on-board LED is connected to on your Arduino
model, check the Technical Specs of your board at:

*/
// the setup function runs once when you press reset or power the board
// esp32 dev module
#include "Arduino.h"
#define led 2
void setup()
{
// initialize digital pin LED_BUILTIN as an output.
Serial.begin(115200);
pinMode(led, OUTPUT);
}
// the loop function runs over and over again forever
void loop()
{
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000);
Serial.println("led is high"); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(1000);
Serial.println("led is low"); // wait for a second
}
9.点击编译
10.编译成功
11.platformio.ini的配置
upload_port 根据实际情况配置，在设备管理器查看
[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
upload_speed = 921600
upload_port = COM3
monitor_port = COM3
12.点击上传
13.上传成功
板载D2 LED开始闪烁
