前言
上两周做了个客制化键盘，将esp8266改在键盘里面了显示始终天气等信息，演示视频看我B站视频：200块改的键盘，没错，你是来听歌的，五分钟剪的视频。
键盘制作教程在最后的参考资料里，自行查看。
之前在网上参考的教程代码都好古老了，一堆问题，而且断网后就会卡在一个界面，天气、时钟是一直在同步网络的，断网后就啥也没了。
最近将代码改了下，包括如下功能：
- 自动同步时间，断网后程序自动计时
- 自动循环播放
- 开机连上wifi后，同步三天天气信息，断网后展示断网前最新一次数据
- 最后加上了我手写的文字，哈哈哈哈，可以自己根据代码改。用PCtoLCD2002自己手写或者图片都行
效果展示
