  • 前言

    之前在做一些小项目时用到了OLED,到网上也找了很多资料,但大多是千篇一律,有些代码的功能也并不能全部实现,而且大多是库函数版,HAL库版本很少。
    这篇博客是我看完很多开源代码后,经过自己的理解,不断对比、优化改写的基于STM32F1/ I2C /HAL库版本的OLED驱动程序。程序中的每一个函数都有详细使用介绍,非常容易上手。


    效果展示

    全屏滚动 并 正反相显示 不同大小的字符串、整数、汉字、图片

    stm32/HAL库版/I2C/0.96寸OLED驱动程序展示

    正反相显示 不同大小的 正负 浮点数

    提示:以下是本篇文章正文内容,下面代码可供参考

    一、OLED驱动的基本功能

    我先大概说一些这个OLED驱动的基本功能:
    1.可以正反相显示8X16,6×8的字符,数字,字符串
    2.可以正反相显示16X16的汉字
    3.可以正反相显示任意大小的图像
    4.全屏水平滚动播放,部分屏幕水平滚动播放 ,全屏垂直水平滚动播放
    5. 屏幕亮度调节,屏幕内容取反显示

    6. 可以正反相显示8X16,6x8的正负浮点数

    预告:接下来将在下一篇文章里面讲述OLED代码的具体原理,主要是讲–>OLED任意位置画点,画沿x轴直线以及沿y轴直线


    二、CubeMX中的设置

    2.1. 配置时钟树

    (1)点击RCC开启HSE和LSE,并选择RC或晶体作为时钟源

    (2)配置时钟树

    最终最右侧显示为

    2.2. 配置I2C

    这里只需将I2C1设置成I2C模式,参数就用默认值就可以。


    三、HAL库代码

    整体代码框架

    3.1. main.c


    /* USER CODE BEGIN Includes */
    #include "../../icode/oled/oled.h"
    /* USER CODE END Includes */
    

     /* USER CODE BEGIN 2 */
     OLED_Init();                           //OLED初始
     OLED_Clear();                         //清屏
    //上面的初始化以及清屏的代码在一开始处一定要写
     OLED_ShowString(0,0,"UNICORN_LI",16, 1);    //反相显示8X16字符串
     OLED_ShowString(0,2,"unicorn_li_123",12,0);//正相显示6X8字符串
     
     OLED_ShowCHinese(0,4,0,1); //反相显示汉字“独”
     OLED_ShowCHinese(16,4,1,1);//反相显示汉字“角”
     OLED_ShowCHinese(32,4,2,1);//反相显示汉字“兽”
     OLED_ShowCHinese(0,6,0,0); //正相显示汉字“独”
     OLED_ShowCHinese(16,6,1,0);//正相显示汉字“角”
     OLED_ShowCHinese(32,6,2,0);//正相显示汉字“兽”
    
     OLED_ShowNum(48,4,6,1,16, 0);//正相显示1位8X16数字“6”
     OLED_ShowNum(48,7,77,2,12, 1);//反相显示2位6X8数字“77”
     OLED_DrawBMP(90,0,122, 4,BMP1,0);//正相显示图片BMP1
     OLED_DrawBMP(90,4,122, 8,BMP1,1);//反相显示图片BMP1
     
     OLED_HorizontalShift(0x26);//全屏水平向右滚动播放
    
    //显示正负浮点数的代码
    //  float num1=-231.24;
    //  float num2=23.375;
    
    //OLED_ShowString(0,0,"Show Decimal",12,0);
    //OLED_Showdecimal(0,4,num1,3,2,12, 0);
    //OLED_Showdecimal(0,6,num2,2,3,16, 1);
    
     
      /* USER CODE END 2 */
    

    3.2. oled.c

    注:
    1.上图中 Set Charge Pump (设置电荷泵)设置为0x8D,0x10即关闭了电荷泵;而程序中笔者开启了电荷泵,故设置为0x8D,0x14。而且把这一步放置在了初始化的最后。
    2.笔者的初始化程序在对比度设置(红色字体处),预充电持续时间等数值大小上与上图不同,其实只要初始化思路一致,这些差异不会影响OLED的使用,这些个性化设置还需好好参读芯片手册

    总结

    以上就是0.96寸OLED的HAL库版本的代码,全部按我这个操作100%一次点亮OLED屏,接下来我将开始学习记录OLED菜单,不久后再写写菜单吧。
    这篇文章主要分享以及记录学习中的感悟,可能还有不足,还望大佬们在评论区提出,大家相互学习与进步。
