构建Arduino命令编译
说明：用户在云端填入联网信息如：esp8266需要连接的wifi信息等。获取信息后在服务端生成esp8266的二进制.hex烧写文件。用户下载.hex文件后，利用烧写工具烧写到开发板中。
搭建arduino-cli
一、参考网址：github库
二、大致步骤：
- 下载安装arduino-cli
https://github.com/arduino/arduino-cli - 测试arduino-cli是否安装成功，
$ arduino-cli sketch new MyFirstSketch
Sketch created in: /home/luca/Arduino/MyFirstSketch
Linux默认创建位置$HOME/Arduino/目录下
Mac os默认位置为$HOME/Documents/Arduino/
- 添加esp8266开发板
在$HOME/Arduino/目录下：创建arduino-cli.yaml文件，填入以下内容
board_manager:
additional_urls:
- http://arduino.esp8266.com/stable/package_esp8266com_index.json
然后运行：
arduino-cli core update-index
arduino-cli core install esp8266:esp8266
查询开发板信息：
arduino-cli board listall
- 查询开发板所属的类型
$ arduino-cli core search nodemcu
Searching for platforms matching 'nodemcu'
ID Version Name
esp8266:esp8266 2.5.1 esp8266
- 编译
arduino-cli compile -b esp8266:esp8266:nodemcu ~/Documents/Arduino/MySketch
遇到的问题

Compilation failed.
解决办法
sudo dd if=/dev/zero of=/swapfile bs=64M count=16
#count的大小就是增加的swap空间的大小，64M是块大小，所以空间大小是bs*count=1024MB
sudo mkswap /swapfile
#把刚才空间格式化成swap格式
sudo swapon /swapfile
#使用刚才创建的swap空间
