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：   

) c+ x! \- t8 T

选择芯片型号

       使用STM32CUBEMX选择芯片stm32f030r8，如下所示：

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：

配置时钟树

    STM32F0的最高主频到48M，所以配置48即可：

3 h- f9 G; I4 _2 h, Z7 sIIC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。

    写好的oled.c放入Src文件夹内，oled.h和oledfont.h放入Inc文件夹内，之后需要在keil中加入这三个文件。

取模

    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。

' q; q6 I6 W6 |0 ^! T取模软件设置
5 n! I/ g* Y* D( Y

    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。

主程序

    main.c中。
