SSD1306 128*32屏幕驱动

最近在做一个小项目，使用合宙air001做主控，arduino开发环境，项目设计一个小屏作为显示，本身使用u8g2库，奈何这个air001空间太小，没写多少就把程序储存空间占满了，log也没办法打印，对于调试分析问题很大，所以想着自己写一个驱动用，

在网上搜索后，现有的代码移植来难以正常显示，没过深研究，一直在摸索修改代码，

经过多天的试错后，基本上可以仿造u8g2的效果，避免以后重复造轮子，特来分享给大家参考。

主要是两个驱动文件，ssd1306.h是字库文件

#ifndef SSD1306_H
#define SSD1306_H

#include <stdint.h>
