概述
I2C总线硬件简单，资源消耗少，只有时钟和数据线。本例程主要讲解如何点亮0.96寸的OLED屏幕，本例程采用的是STM32F030R8T6，64K大小的Flash。

硬件准备
) q, Y8 J9 g/ x' O. E首先需要准备一个开发板，这里我准备的是NUCLEO-F030R8的开发板：

6 j" t5 v/ C* Q# W. x9 M$ N+ P0 f

选择芯片型号
使用STM32CUBEMX选择芯片stm32f030r8，如下所示：
, t3 m, p$ A9 h- }' K7 `" p6 H
& K3 ~5 [+ g/ l
  x- v5 I4 {8 ^+ I
配置时钟源
% `5 ~" T, X7 |HSE与LSE分别为外部高速时钟和低速时钟，在本文中使用内置的时钟源，故都选择Disable选项，如下所示：
* w: V$ S- A) {2 Z( W
. E  \! K3 c+ `

配置时钟树
) y5 \. w9 k4 Z7 u" W% qSTM32F0的最高主频到48M，所以配置48即可：

取模
, v# W4 R, i' K5 R5 d由于单片机的flash比较吃紧，所以要显示汉字需要先进行取模。

( N2 |# m/ ^% H' a取模软件设置

/ D( _$ [6 `/ }' W0 S- Z设置完之后就可以取自己想要汉字的编码，输入完毕点击生成字模即可。

将取得的编码放入oledfont.h的Hzk数组中即可。
