上一篇文章讲解完环境的搭建，我们就直接跳到讲OLED的显示

因为像led亮灭都比较简单，所以就没讲了，就是一个Gpio的输出高低电平就能实现，相信玩过单片机的同学们都懂。

我就先把代码贴出来

相信看到代码的同学也是觉得这个跟32oled显示都是一样的，我也是这样觉得。
但是初始化函数还是需要我们去写的,因为这个是用IIC的0通道来进行通信，而且代码里面有帮我们初始化好iic的API，我们就只是需要去修改我们的复用IO功能
打开这个路径下文件app_io_init.c
然后就按照圈住的地方，修改IO口，和这一次用到的iic0
然后接着打开这个路径下的文件module_config.mk

然后添加圈住地方添加上

CONFIG_I2C_SUPPORT=y；

最后最后记得在目录app编辑的BUILD.gn

oled显示就这样啦。
如果上面有问题请大佬指出，谢谢。

最后的显示效果
