简介

合宙esp32c3 micropython框架，只支持128*64 I2C oled

ssd1306驱动我优化过的，与其他的不一样，为避免出错，使用我的驱动

把下面两个py文件放入单片机内，

实现思路

从网站获取天气数据，根据文本的字典结构，为了方便，转成json进行有效信息的提取。

获取的天气状态一共有小雨，中雨，大雨，阴，晴，多云

按照天气状态分为两组，两个字的和一个字的

设置了一个查找树，对两个字的进行快速查找，优化if结构

如果选择好了天气状态，就在特定位置显示中文（16*16）和天气状态对应的图（32*32）

剩下的就是显示城市和温度了

我的代码默认是广州，你也可以更改其他城市

在font.py中，我以笔画的方式存储了天气状态对应的中文，还有‘广州’对应的中文，相当于自己建立了一个小字库，当然也可以更改为其他方式显示中文，如取模，烧写特殊固件
