入坑esp-01s 1.3寸OLED时钟及天气显示（三）

先上图：

基本模样已经完成。左右双屏各自显示的内容也已完成。左边只显示时间，右边只显示天气。

网上的方案是单屏循环显示时间和天气，屏幕小，我总觉得不过瘾，所以改成双屏，也变相地加大了屏幕面积，难度没怎么增加。

原来只显示英文，这也是esp01s的缺点，内存太小，只有1M，显示完全中文很难实现。但我改成了显示星期，好看点，内存里面只增加“星期一二三四五六日”这9个汉字，占用内存小。下一步打算反农历也加上去，研究了一下，C++计算农历还挺麻烦，不如python,一个库就搞定了。慢慢 研究，应该可以做完。下面是左右屏的代码。我是在别的代码上改的，肯定有些没用的代码，暂时还没精减，而且我的C++也是刚接触，很多代码我都不敢动，动一下可能就出问题。大神不要笑！再次感谢开源的大神！

还有件事没说，打算买个3D打印机打印外壳，做完可能就更好看点，又要学习3D画图了。我还有几个类似的东西，也一齐做出外壳，弄个全家福啥的。
