我要评论
## 阅读须知
阅读本文需要有一定的STM32基础。
## 前言
我经常用的是IIC驱动，因为只有2个IO口，使用也方便。
前段时间拿到SPI接口的OLED，于是就去捣鼓了三线SPI驱动。
本驱动适用SSD1306，其他芯片的鄙人没有测试，仅供参考。
SSD1306手册：https://cdn-shop.adafruit.com/datasheets/SSD1306.pdf
代码中的宏定义对应接线：
OledCS ：CS--->PB12
OledRS ：DC--->PB14
OledRst ：RES-->PB13，可以直接接单片机RST引脚
OledSck ：D0--->PB0
OledSdin：D1--->PB1
//OLED模式设置
//0: SPI串行模式 （模块的BS1，BS2均接GND）
//1: 并行8080模式 （模块的BS1，BS2均接VCC）
#define OLED_MODE 0
//SPI模式设置
//0: 4线串行模式 8 bit data send
//1: 3线串行模式 9 bit data send
#define OLED_SPI_X 0
## 驱动原理
不管是IIC还是三线SPI、四线SPI，乃至8080并口驱动OLED，他们的本质都是一样的：写数据和写命令。也就是说当你已经有一份可以驱动的代码，你就可以很快的修改成其他接口协议来驱动OLED。
如果是7针的OLED，接线和改电阻参考（也可以直接看元器件的丝印）：
https://wenku.baidu.com/view/42efcb877cd184254a353584.html
### IIC驱动OLED
没有什么好说的，直接上源码。
最后得出2个函数，写命令和写数据函数，然后拿着这2个函数去写OLED操作。如显示数字、字符、字符串、中文，
void WriteCmd(u8 command)；
void WriteDat(u8 data)；
只要其他接口实现这2个函数的功能，那么就可以在IIC接口的驱动延伸出其它接口的OLED驱动。开始，写底层驱动~~~。
为了不影响阅读，OLED显示代码我放在最后。

### 四线SPI驱动OLED
四线SPI使用CS、D0、D1、DC。分别对应SPI的CS、Sck、Sdin、命令数据选择。
注：RES是要使用的。
官方说明：
第一段是说使用到什么线的，每一个IO的功能。
第二段是告诉你怎么编程的。
### 对应的编程，这里只考虑写，不考虑读取。以下为写8bit。
void OLED_WR_Byte(u8 dat,u8 cmd)
{
char i;
OledCs_L();//片选
if(cmd) //判断是写数据还是写命令
OledRS_H();
else
OledRS_L();
for(i=0;i<8;i++)//8bit
{
OledSck_L();
if(dat&0x80)
OledSdin_H();
else
OledSdin_L();
OledSck_H();
dat<<=1;
}
OledCs_H();
OledRS_H();
}
### 三线SPI驱动OLED
三线SPI使用CS、D0、D1。分别对应SPI的CS、Sck、Sdin。
注：RES是要使用的。
官方的说明：
第一段是说使用到什么线的，每一个IO的功能。
第二段是告诉你怎么编程的。这里说一下三线SPI的原理：其实就是一次发9bit数据，把命令/数据使用Sdin线的1bit，（1：写数据，0：写命令）而在四线SPI中，根据D/C线的电平判断写命令还是写数据。
### 对应的编程，这里只考虑写，不考虑读取。
那么我们就再四线SPI的基础上加上几行（配合宏定义）：
void OLED_WR_Byte(u8 dat,u8 cmd)
{
char i;
OledCs_L(); //片选
#if OLED_SPI_X == 1//如果定义了三线SPI
OledSck_L();
if(cmd) //判断是写数据还是写命令
OledSdin_H();
else
OledSdin_L();
OledSck_H();
#else //四线SPI
if(cmd) //判断是写数据还是写命令
OledRS_H();
else
OledRS_L();
#endif
for(i=0;i<8;i++)//8bit
{
OledSck_L();
if(dat&0x80)
OledSdin_H();
else
OledSdin_L();
OledSck_H();
dat<<=1;
}
OledCs_H();
#if OLED_SPI_X == 0//四线SPI
OledRS_H();
#endif
}
### 8080并口驱动OLED
并口比较简单，和以前使用的LCD12864差不多，鄙人没有条件测试。不做任何保证，仅供参考。
void OLED_WR_Byte(u8 dat,u8 cmd)
{
DATAOUT(dat); //先输出数据
if(cmd) //判断是写数据还是写命令
OledRS_H();
else
OledRS_L();
OledCs_L();
OledWR_L();
OledWR_H();
OledCs_H();
OledRS_H();
}
### 写数据和写命令函数
上面的所有驱动，都要实现OLED_WR_Byte函数的功能，然后使用OLED_WR_Byte封装出写命令和写数据的函数和IIC驱动一致。这样就可以使用原本IIC驱动的操作函数。封装如下：
void WriteCmd(u8 command)
{
OLED_WR_Byte(command,OLED_CMD);
}
void WriteDat(u8 data)
{
OLED_WR_Byte(data,OLED_DATA);
}
