STM32CubeMX学习笔记5——I2C配置（OLED显示)

文章目录

一、打开Cube，建立工程
二、系统配置
三、配置iic
四、在 Clock Configuration中:
五、工程输出配置
六、代码部分处理

MCU：STM32F103ZET6
IDE： MDK-ARM V5 +STM32CubeMX5.2.1

一、打开Cube，建立工程

图片：在这里插入图片描述
点击ACCESS project from MCU
然后选择芯片类型
图片：

二、系统配置

在 Pinout&Configuration—System Core中:
设置时钟RCC的HSE（外部高速时钟）为晶振模式：
Crystal/ceramic Resonator：在这里插入图片描述
设置系统SYS的Debug为Serial Wire(SWD调试)：

三、配置iic

选择i2c，配置采用默认的即可
在这里插入图片描述

四、在 Clock Configuration中:

配置时钟为72 Mhz。
在这里插入图片描述

五、工程输出配置

在这里插入图片描述
Tips：最好把Linker Settings中的Minimum Heap Size设置为0x600。

最后点击GENERATE CODE代码就生成了:

至此，一个工程就创建完了。

六、代码部分处理

创建字库头文件oledfont.h

    #ifndef __OLEDFONT_H
    #define __OLEDFONT_H 	   
    // ------------------  ASCII字模的数据表 ------------------------ //
    // 码表从0x20~0x7e                                                //
    // 字库:  纵向取模下高位// （调用时要减512）
    // -------------------------------------------------------------- //
