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

    首先需要准备一个开发板，这里我准备的是NUCLEO-F030R8的开发板：   
4 A8 |6 `- g: u1 F

2 F! g! [: }1 I9 t

选择芯片型号

       使用STM32CUBEMX选择芯片stm32f030r8，如下所示：

$ r- S% n! b( p9 L" E* e* S; {

配置时钟源

    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：

' [; f* b0 V- t6 g0 U配置时钟树

    STM32F0的最高主频到48M，所以配置48即可：

1 Z- O+ _$ t3 y7 w% Q# O* c/ o

8 U3 O: M, O6 a9 ~# b0 kIIC配置

    本次实验使用的IIC与显示屏通信，配置如下。

生成工程设置

    注意在生产工程设置中不能出现中文，不然会报错。
