1. 概述
本文着重描述基于VsCode搭建ESP32产品线开发环境，系统环境为WIN10。
2. 安装操作步骤
2.1 安装VsCode
下载地址：VsCode官方网站
安装过程：略，无脑下一步即可。
2.2 安装espressif idf扩展
2.3 配置espressif idf插件
- 在VsCode界面下，可以按【F1】键或选择【查看->命令面板】打开命令选择器，选择【ESP-IDF：配置ESP-IDF插件】
- 在出现的界面上选择【Express】快速配置选项，如图
- 选择后，配置如下，点击INSTALL，需要等一段时间，要装很多东西。
- 安装界面如图：
- 安装成功，提示如下：
3. 跑通第一个Demo
前提条件:需要有ESP32开发板，我手里的开发板为ESP32-DevKitM-1 v1.0
- 在VsCode界面下，选择【查看】->【命令面板】->选择【ESP-IDF：展示示例项目】
- 创建示例工程
- VsCode IDE工具简述
- 工程配置步骤
- 选择目标芯片ESP32
- 点击左下角的齿轮图标，打开工程配置界面，如图，这里功能简单，无需配置。
- 选择目标芯片ESP32
- 编译工程
编译成功如图：
- 烧写固件到ESP32开发板
- 程序烧写日志如下:
