有一点思考，有一点想法，有一点理性

概述

某宝上买的 OLED，IIC/SPI 都可以，买来看的时候发现背面焊的是 SPI。板子上又没有硬件 SPI，只好用软件模拟 SPI。很久之前学的了，现在把它写在 CSDN 上，各位大佬如有什么想法，欢迎评论！（PS：==文末会附上此工程的全部文件，欢迎下载交流==）

去年的一篇文

3.1 硬件设计

硬件方面不多讲，直接看某宝上图片。

某宝上介绍的比较详细，需要注意的是==这个 OLED 可以焊接电阻 R1~R4 中的某几个来选择 IIC 或者 SPI 协议==，详情见以下图片

3.2 软件设计

3.2.1 编程要点

1、初始化 GPIO 口来模拟 SPI，每个人设置的 GPIO 口不同，开发板与 OLED 接线也会不同，所以在拿到别人的程序代码时，==一定要看看 ta 是用那几个 GPIO 口来模拟的，不要看 ta 程序开头的注释，很有可能 ta 后面把模拟的 GPIO 口改过，而注释没改==

2、OLED 驱动程序，这里的驱动程序可以参考别人写的，然后自己再加以修改或者补充。

3、取模，包括文字取模和图片取模。根据自己的需要来取模。需要取模软件的可以私信我。

3.2.2 代码分析

1、OLED 驱动头文件 oled.h
