arduino写8266 IIC驱动OLED显示屏 （小E开发板）8266系列通用
虽然资料没有U8glib和u8g2那么详细，但是能用8266驱动已经不错了，后面有空在折腾
库有很多可以自己去试试那个好，欢迎留言 ！
搜索1306（因为这个OLED芯片是1306，这是以前自己搜索的资料然后实验出来的 ）
搜索出来版本很多 各种写法都不一样 ，可以自己实验一下 ，
安装了然后在示例里面有个代码
然后呢重点来了：
SSD1306Brzo display这个函数里面就是接那个脚的 我查了下官方的资料是2和14脚
然后
SSD1306Brzo display(0x3c, SDA, SCL);
填上自己对应的脚就是 （通用ESP8266系列）
SSD1306 display(0x3c, 2, 14);
然后上传试试
忘记说怎么下载了：
更据官方的资料 安装BOOt这个键然后在把开关拨打开！然后上电 （个人测试了上电后按了下载失败的）
这哈就能看到了 （小E开发板要吧1开关拨上去）我这是直接连接的IO所以不管
相信应该有人也像我一样，用arduino的板子能直接用U8g的库能驱动oled屏幕，可用esp8266的始终不行，我也是用库的时候才想起可以直接搜索，然后试试就点亮了 ！有问题回帖，如果没及时回复QQ496631085
以下是修改了脚的代码：
