STM32CubeIDE——HAL库硬件IIC通讯(SSD1306 OLED屏幕点亮)_第1张图片

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

STM32CubeIDE——HAL库硬件IIC通讯(SSD1306 OLED屏幕点亮)_第2张图片

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。

STM32CubeIDE——HAL库硬件IIC通讯(SSD1306 OLED屏幕点亮)_第3张图片

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。
