2.代码编写

 

1.工程配置

028fc620b1cb4666b5c8f72ca5eca16c.png

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

  1. /* USER CODE BEGIN Includes */
  2. #include "oled.h"
  3. /* USER CODE END Includes */

屏幕初始化

  1.   /* USER CODE BEGIN 2 */
  2.   OLED_Init();
  3.   /* USER CODE END 2 */

oled显示

  1.   /* USER CODE END WHILE */
  2. 	    OLED_ShowCN(20, 1,0);
  3. 		OLED_ShowCN(40, 1, 1);
  4. 		OLED_ShowCN(60, 1, 2);
  5. 		OLED_ShowCN(80, 1,1);
  6. 		HAL_Delay(2000);
  7.     /* USER CODE BEGIN 3 */

然后烧录进去观察屏幕现象就可以了。
