如何编写0.96寸OLED的底层驱动？

1、在STM32CubeMx里面进行配置

1.1、打开STM32CubeMx，点击“ACCESS TO MCU SELECTOR”；




1.2、基于我的开发板为STM32F103VCT6，因此选择芯片型号为STM32F103VCTx，然后点击“Start Project”生成一个新工程；





1.3、点击“System Core”下的“SYS”，因为我自己用ST-LINK下载，因此将"SYS"配置为“Serial Wire”；





1.4、如果需要外部时钟的话就点击“RCC”进行外部时钟配置，具体的参数根据自己的开发板需要进行设置；如果要显示最好还是要配置成32MHz。










1.5、进行IIC配置，默认选用芯片的PB6、PB7作为SCL和SDA引脚，点击芯片的PB6、PB7引脚，在下拉的模式里面选择I2C1_SCL以及I2C2_SDA，在左侧的“Connectivity”中选择“I2C1,在打开的界面中点击选择“I2C”，其他参数默认即可；说一句，在这里如果直接在左侧的“Connectivity”中选择“I2C1,也可以，我这属于有点多此一举。








1.6、点击"Project Manager",输入文件名，将“Toolchain/IDE”选为"MDK-ARM"，点击“Code Generator”，将“Generate peripheral …”勾选，最后点击“GENERATE CODE”生成代码；









到此为止，在STM32CubeMx上的配置则全部完成，接下来的工作将在Keil中完成。

如何用这三个驱动代码呢？
首先在桌面上新建三个TXT文本，依次将这三个代码复制进去然后更改文件名为“oled.c”、“oled.h”、“oledfont.h”，然后将“oled.c”文件复制到STM32CubeMx生成的“OLED_CESHI”文件夹中的“Src文件夹”中，将“oled.h”、“oledfont.h”文件复制到STM32CubeMx生成的“OLED_CESHI”文件夹中的“Inc文件夹”中。
2.2、打开“OLED_CESHI”下"MDK-ARM"文件夹中的“OLED_CESHI.uvprojx”文件，在“Application/User”中添加“oled.c”，编译一遍（应该没有错误嘿嘿）；
2.3、点击main.c，在头文件处添加“ #include “oled.h” ”,
其中，主函数代码如下所示：


int main(void)
{
  /* USER CODE BEGIN 1 *//*用户代码开始1 */


  /* USER CODE END 1 *//*用户代码结尾1 */
  


  /* MCU ConfigurationMCU配置--------------------------------------------------------*/


  /* Reset of all peripherals, Initializes the Flash interface and the Systick. *//*重置所有外围设备，初始化Flash接口和Systick。 */
  HAL_Init();


  /* USER CODE BEGIN Init *//*用户代码开始初始化*/
  
  /* USER CODE END Init *//*用户代码结束初始化*/


  /* Configure the system clock *//*配置系统时钟*/
  SystemClock_Config();


  /* USER CODE BEGIN SysInit *//*用户代码开始SysInit */


  /* USER CODE END SysInit *//*用户代码结束SysInit */


  /* Initialize all configured peripherals */
  MX_GPIO_Init();
  MX_I2C1_Init();
  /* USER CODE BEGIN 2 *//*用户代码开始2 */
          OLED_Init();
        OLED_Clear();
        OLED_ShowString(0,0,"www.taxing.com",16);
        OLED_ShowCHinese(0,4,0);//
        OLED_ShowCHinese(16,4,1);//
        OLED_ShowCHinese(32,4,2);//
        OLED_ShowCHinese(48,4,6);//
        OLED_ShowCHinese(0,6,3);//
        OLED_ShowCHinese(16,6,4);//
        OLED_ShowCHinese(32,6,5);//
        OLED_ShowCHinese(48,6,6);//
  /* USER CODE END 2 *//*用户代码结尾2 */
  /* Infinite loop *//* 无限循环 */
  /* USER CODE BEGIN WHILE *//*用户代码开始时*/
  while (1)
  {
    /* USER CODE END WHILE *//*用户代码结束时*/
               
    /* USER CODE BEGIN 3 *//*用户代码开始3 */
  }
  /* USER CODE END 3 *//*用户代码结尾3 */
}


效果图如下所示：
