一、前言

作为土木专业的本科生，在 STM32 的探索路上，我们已经完成了串口控制 LED、触摸按键点灯、按键交互等基础实战。这次我们将更进一步，解锁SSD1306 驱动 OLED 屏幕的核心技能 —— 这是嵌入式开发中最常用的显示方案，也是后续做数据可视化、人机交互的基础。

由于是非专业出身，我会尽量从硬件原理、代码实现到效果调试，全程手把手带你从零点亮 128×64 分辨率的 SSD1306 OLED 屏幕，哪怕是零基础也能跟着完成。

我担心我讲的不好，或者原理性的理解有问题，为了大家方便，特此在下方提供了其他专业博主的视频链接，若是有问题或者疑问的地方，也可以查看哦。链接如下：

keysking：【STM32入门教程-2025】第14集 如何在OLED屏幕上挥毫_哔哩哔哩_bilibili

高博士：[10-03]OLED屏工作原理简介_哔哩哔哩_bilibili

对上述两个视频链接中原理的讲解，我听的有点云里雾里的，哈哈，oled屏幕点亮是可以点亮的，毕竟有大佬做好了基础，我们把模块化的东西搬过来组合成我们自己的东西就好。

二、核心原理：SSD1306 OLED 屏幕是什么？

1. 核心参数与特性

  • 驱动芯片：SSD1306（OLED 屏幕的 “大脑”，负责控制每一个像素的亮灭）

  • 分辨率：主流为 128×64（128 列、64 行像素，总像素数 8192 个）

图片来自keysking的视频

  • 通信接口：支持I2C、SPI、并行，其中I2C 接口是最常用的方案（仅需 2 根信号线，接线简单）

  • 供电：3.3V（部分模块支持 5V，STM32 开发板直接用 3.3V 供电即可）

  • 优势：自发光、对比度高、视角广、功耗低，适合嵌入式低功耗场景

2. 工作原理

SSD1306 芯片内部自带显存（GRAM），我们只需要通过 I2C/SPI 向芯片发送指令和数据，芯片就会自动将显存内容刷新到屏幕上。

  • 指令：用于配置屏幕（初始化、开关显示、设置显示区域、对比度等）

  • 数据：对应屏幕上的像素点（1 个字节控制 8 个垂直像素，1 点亮，0 熄灭）

对于原理性的内容，可能有一些枯燥，甚至是不是很理解，大家只要知道到这个屏幕是由一个个点组成，那要实现屏幕出现我们想要的文字，是不是只要一些点组成文字就好了？那要怎么实现这些点亮起，组成这个文字的全部坐标，如下图蓝色的字母A，就是由一个个点组成。

图片来自高博士的视频

说了这么多，原理可能还是不理解，没有基础的确是有点难理解，哈哈，没关系，我在下面的实战中，会带领大家把大佬们已做好的驱动程序代码拿来拼装，不要害怕。

三、直接动手实战（硬核高能内容）

我们使用 STM32CubeIDE + HAL 库开发，全程用 HAL 库函数实现，避免了寄存器操作，降低上手难度。

1、打开STM32CubeIDE软件，选择stm32f103vet6芯片，新建项目：OLED_TEST

2、为防止f103芯片被锁芯片，修改sys的debug模式，如下图所示

3、通信方式选择i2c，为了可能数据量大，反应能够快一些，更改了速度为高速模式

4、rcc选择外部晶振的时钟，时钟树那里设置为72mhz，并单独生成i2c相应的.h和.c文件，如下图所示

5、点击菜单栏的齿轮，生成代码

生成代码以后的情况

6、利用大佬们已经编写好的驱动代码，将其移至到我们的项目中（重点）

可利用的驱动资源有两个，一个是keysking，另外一个是高博士的代码仓库。链接和截图如下：

keysking：波特律动LED字模生成器

高博士：3 例程_hal库_cubeide/1001I2C_OLED.zip · gaoyanzeng/drg_st_2_f103vet6 - 码云 - 开源中国

有挑战意愿或者兴趣的同学，可以尝试一些利用keysking的资料包，试一试看能不能让屏幕亮起来。我这里为了节约时间，我后续的操作采用了高博士的资料。

下载高博士的oled程序，将其中的三个文件导入或者复制粘贴到我们的项目文件中去。

在这里大家根据截图中的路径，看一下怎么找到这个三个驱动文件。

打开以后的oled_i2c.c代码如下：

oled_i2c.h代码如下：

几个可以copy的内容拿到了，我们可以先试试，直接不修改他的代码，先成功让oled屏幕显示广告词，后续再修改内容，让它显示我们想要出现的汉字英文或者数字等等内容。

我这里是利用记事本打开main.c、oled_i2c.c、oled_font.h、oled_i2c.h

软件的设置还是和之前是一样的，在三、直接动手实战（硬核高能内容）这里的第5步，已经生成了初始的代码。

下面可以直接把下载过的驱动代码，直接拖入inc、src中去，下面中的图片是已经拖如了的。

另外的一个方法就是自己新建.c和.h文件。由于电脑按键截屏存在一定问题，我就用手机拍了一下怎么新建后文件。

同样的，可以新建.c文件

建完以后，如果不用拖入或者导入文件的方式，大家可以用记事本打开几个代码内容，复制粘贴代码也行。高博士的是在driver文件夹新建了（需要修改一下路径），我们也可以在core中新建，这样可以不用修改路径。

代码粘贴进去以后的情况

由于这部分有点多，也比较烦，我这个帖子结束以后，会陆续更新实验的视频，请大家静待哔哩哔哩作品更新。

不会c的小谢的个人空间-不会c的小谢个人主页-哔哩哔哩视频

7、点击小锤子编译代码无误后，烧录代码进单片机。

这个是下载高博士代码，复制它的东西显示的东西，那我们要怎么修改其中的内容，变成我们自己的呢？

8、利用取字模软件工具或者其他工具，修改代码，替换我们自己的东西。

比如我想在屏幕上面显示：hello 小谢 2026.4.6

在文章的前部分内容我们已经看到了相关取字模工具，大家需要把它下载过来，并且解压。

6 板上器件手册 · gaoyanzeng/drg_st_2_f103vet6 - 码云 - 开源中国

双击打开取字模软件pctolcd2002

这里需要对字模选项进行设置，不然中文会出现一定的问题

将取字模后的代码复制过来，替换掉原来的高博

重新烧录代码，便可以看到以下的情况。

有条件的同学可以尝试一下keysking的取字模工具，大佬可以在屏幕上将ikun展示出来哦

显示中文的这一部分内容略有点难度哦，大家可以好好地利用下ai工具辅助一下。

由于本人非科班出身，原理解释和理解上可能存在一定问题，请大家谅解哈。

有问题的小伙伴可以在评论区留言，或者是在后续的实践视频下留言评论。

学无止境，大家一块加油哦！！
