STM32CubeIDE——HAL库硬件IIC通讯（SSD1306 OLED屏幕点亮）
目录
1.工程配置
oled.c源代码
oled.h源代码
文件夹放置
单片机型号修改
2.代码编写
1.工程配置
选择I2C1通讯端口，配置工程文件。
IIC通讯需要设备地址，可以根据屏幕具体电阻接法确定，此处使用硬件IIC，所以无需配置。
使用oled屏幕需要oled.c，oled.h，以及字库文件.h ，同时加入到相应的文件夹中。

文件夹放置
将以上三个文件加入到图中相应位置
单片机型号修改
我使用的是STM32f103c8t6，对应头文件为stm32f1xx_hal.h，如果使用其他型号单片机，需要将oled.c和oled.h文件中对应头文件修改，下图对头文件对应所在文件夹位置。
2.代码编写
oled使用需要头文件引用，屏幕初始化，之后按照oled.c文件中定义函数使用即可，如需使用汉字，则需要在字库文件中使用取模软件，将汉字取模写入字库文件中再进行显示。
头文件引用
/* USER CODE BEGIN Includes */
#include "oled.h"
/* USER CODE END Includes */屏幕初始化
/* USER CODE BEGIN 2 */
OLED_Init();
/* USER CODE END 2 */oled显示
/* USER CODE END WHILE */
OLED_ShowCN(20, 1,0);
OLED_ShowCN(40, 1, 1);
OLED_ShowCN(60, 1, 2);
OLED_ShowCN(80, 1,1);
HAL_Delay(2000);
/* USER CODE BEGIN 3 */然后烧录进去观察屏幕现象就可以了。
