OLED 12864 IIC的是双色屏程序 楼主注意几个问题，
1、主控，这个驱动能不能用取决于你的屏的主控
2、默认值，很多主控具有上电或重启后的默认值，比如很多小 OLED 主控是 SSD1306、1309，它手册写了那些是默认值，如果是默认值的你不需要重复发送这些配置指令去初始化它。
此外，最好拿到屏幕制造商的说明，看看哪些项目应该配置为非默认值。比如从左往右还是从右往左、从上往下还是从下往上写，其实和你的屏幕安装方式有关，你要倒过来 180 度安装屏幕，写顺序就要反过来，否则就可以用默认值不需要配置。

谢谢分享！ 谢谢分享正需要 一般买这类OLED屏都给出非常详尽的程序，百度上的文库也可以通过软件免费下载。 感谢楼主，屏驱动确实是问题，所以我用ARDUINO标准库，这样就很简单了
