@[TOC]stm32 OLED显示

1、OLED基本结构

大小：128X64个点阵
X方向128bit
Y方向64B，且分为8页，一页8B
在这里插入图片描述

2、显现原理

当对应的某一个像素点为1时，对应的小方格点亮。且每一列对应一个字节，低位在最上面，高位在下面

3、字体大小

一般英文8X16，中文16X16

4、驱动芯片（SSD1306）

SSD1306常用命令
在这里插入图片描述

5、将文字写入相应的位置

需要设置同时两个命令，一个是列地址低4位命令，一个是列地址高4位命令，假如我当前要锁定第125列，125对应的16进制是0x7D，那么我只需要同时发0x17和0x0D就可以了（其中没有先后顺序）

6、字模的获取

（1）我用的是PCtoLCD2002完美版
在这里插入图片描述
（2）取模方法
在这里插入图片描述
如果想要显示图片则选择图片模式（注意选择图片模式，图片不能是彩色，只能是纯白和纯黑的组合，且图片是BMP文件，像素大小不能大于128X64）
在这里插入图片描述在这里插入图片描述
（3）设置好后，可以在方框内输入自己需要显现的文字
在这里插入图片描述在这里插入图片描述
(4）再将生成的字模复制到文件中即可

7、和单片机相连常用的协议

I2c,和SPI

8、以下为用I2C实现OLED的显示的主要代码
