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:在这里插入图片描述

二、系统配置

在 Pinout&Configuration—System Core中:
设置时钟RCCHSE(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SYSDebugSerial Wire(SWD调试)在这里插入图片描述

三、配置iic

选择i2c,配置采用默认的即可

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

Tips:最好把Linker Settings中的Minimum Heap Size设置为0x600。
在这里插入图片描述
最后点击GENERATE CODE代码就生成了:
在这里插入图片描述
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

    // 字库:  纵向取模下高位// (调用时要减512)
