【STM32 H533RE】测评九_spi加oled的简单测试

备注：最后一节，也就是计划中的spi部分，整体项目因为LS原因先不上传，预计6月底会把整个项目端上来，其他的后续再说吧，现阶段就先按照计划做到这里，spi部分跟IIC部分类似，同样都是调库驱动显示屏，大部分驱动市面上都已经成型了，不再多说（原理也不讲了，之前记得应该写过帖子，不太清楚了），步骤如下：

一、cubemx部分

1、RCC

 

2、时钟树

 

3、SPI配置

  

二、代码部分

先把oled的三个文件写好，扔到src和inc里面，直接在ide新建之后再复制粘贴也可以用

引脚部分自己注意点，这部分就不说明了。

然后是主函数部分，简单写个测试就行

登录后复制
  •  /* USER CODE BEGIN 2 */

  • // 初始化 OLED

  •     OLED_Init();

  • 

  •     // 清屏

  •     OLED_Clear();

  • 

  •     // 显示静态文本

  •     

  •     // 显示动态数值

  •     float temp = 24.6;

  •     float humi = 45.2;

  •   /* USER CODE END 2 */

  • 

  •   /* Infinite loop */

  •   /* USER CODE BEGIN WHILE */

  •   while (1)

  •   {

  • 		// 清除之前的数值显示（避免重叠）

  •         OLED_ShowString(10, 30, (uint8_t *)"Temp:       ");

  •         OLED_ShowString(10, 50, (uint8_t *)"Humi:       ");

  • 

  •         // 显示新的数值

  •         OLED_ShowFloat(temp, 1, 60, 30);

  •         OLED_ShowFloat(humi, 1, 60, 50);

  • 

  •         // 模拟温湿度变化

  •         temp += 0.1;

  •         if (temp > 30.0) temp = 24.6;

  • 

  •         humi += 0.2;

  •         if (humi > 50.0) humi = 45.2;

  • 

  •         // 刷新显示

  •         OLED_Refresh_Gram();

  • 

  •         // 延迟 500ms

  •         HAL_Delay(500);

  •     /* USER CODE END WHILE */

  • 

  •     /* USER CODE BEGIN 3 */

  •   }

  •   /* USER CODE END 3 */

最后测试结果如图
