1、利用官方途径进行下载安装
(1)首先在Arduino中添加 esp32 开发板地址:
打开Arduino后选择:文件 > 首选项 > 附加开发板管理器网址中加入Arduino for esp32包的地址:
https://dl.espressif.com/dl/package_esp32_index.json
(2)IDE——工具——开发板——开发板管理器——搜索“ESP32”——安装
(3)安装成功
2、直接下载esp32数据包的压缩包,手动解压并添加,下载地址:
(1)https://github.com/espressif/arduino-esp32
(2)百度云下载链接:https://pan.baidu.com/s/1mC-DGFKhKsS4kjKz50mung
提取码:86le
(3)解压后,将压缩文件里的内容复制到如下路径(需要新建一个espressif文件夹):Arduino > hardware > espressif > esp32 ,最后放到esp32文件夹下。
此时再打开Arduino IDE 编译器,工具 > 开发板 已经可以找到ESP32相关开发板
编译环境现已设置完毕,可以上传一个测试程序。
