好几天没有发贴了，今天发贴来说下FireBLE的OLED移植，就是把官方的OLED应用到自己的项目中来，虽然坛子里有FireBLE的OLED的文章，但是没有讲清楚，只不过是在官方的例子中自己加了个字库，换了个文字而已。好了废话不多说了，开始吧。
实验目的：
把官方OLED移植到自己的项目中来。（我是移植到MPU6050项目中，实时显示 开发板的姿态数据）
实验电路：
实验步骤：
1、首先把官方的OLED三个文件复制到自己的项目中来（oled.h、oled.c、oledfont.h）
2、在keil的工程选项中添加两个宏定义：FB_OLED,FB_SPI_OLED
3、用Qblue配置IO
实验代码：
