本文使用的自制电路板芯片是“STM32G030F6P6”以及ST-LINK v2下载工具，采用内部高速晶振。不同的SMT32芯片，基本配置都是一样，只需要做稍微的更改即可，后面会提到需要更改哪些地方。

该程序使用模拟IIC，不是硬件IIC，只需将SCL，SDA对应的STM32G030F6P6引脚设为推挽输出即可，另外注意移植代码时需要修改为对应引脚。

该程序在CubeMX下完成，该程序基于中景园STM32标准库函数示例程序修改的。标准库函数例程和本案例完整代码工程获取方式为公众号回复IIC驱动获取下载地址。

2 如何利用STM32驱动OLED液晶屏

2.1基本配置

首先利用CubeMX工具进行基本配置，配置内容主要包括设置PB6、PB7为输出模式；设置PB14和PB13为SWCLK调试接口；设置PA12下拉输输出模式和PA11为上拉输入模式。时钟采用芯片内部高速时钟，部分配置如下图所示。

2.2 1.54OLED端口含义

IIC接口的OLED引脚有四脚，如图所示分别为

2.3 1.54OLED液晶屏引脚与STM32引脚的硬件连接

这里OLED的SCL接STM32的PB7,SDA接单片机的PB9,如果采用模拟IIC，这两个引脚是可以随意改动，只需要在CubeMX上事先配置好对应引脚为OutPut模式。这里接PB9和PB7，因为这两个引脚可以作为硬件IIC使用。

2.4 1.54寸OLED液晶屏驱动程序

首先修改oled.c文件，删除#include "delay.h"，将u8全部替换为uint8_t；将u16全部替换为uint16_t；修改OLED的初始化函数，删除如下代码，因为初始化已经在主函数通过MX_GPIO_Init()实现。将delay_ms(200)用HAL_Delay(200)替换。

接下来修改oled.h文件，这里主要是将对连接OLED的SCK和SDA的两个标准库读写操作用HAL库操作。
