OLED SPI 端口定义
本节引自STM32驱动0.96寸OLED液晶屏(12864液晶屏) —— 小牧同学
两种屏幕的引脚数不一样，左边的有7个引脚，而右边的只有6个。其次，端口的标号也不完全一样，第一个分别标为GND，VCC，D0，D1，RES，DC和CS第二个分别标为GND，VCC，SCL，SDA，RST，D/C。
七针OLED引脚定义
GND — 接地端口
VCC — 接3.3V电源端口
D0 — CLK时钟信号(等同于上面的SCL)
D1 — 数据端口(等同于上面的SDA)
RES — 复位端口(等同于上面的RST)
DC — 数据/命令选择引脚(等同于上面的D/C)
CS — 片选引脚(低电平有效，也就是所需要接低电平，我实际试验过不接该引脚也是可以正常使用的)
六针OLED引脚定义
GND — 接地端口
VCC — 接3.3V电源端口
SCL — CLK时钟信号端口
SDA — MOSI数据端口
RST — 复位端口
D/C — 数据/命令选择引脚

指令解读见【51单片机快速入门指南】4.2： SSD1306 OLED屏（0.96寸、1.3寸）的I2C控制详解
软件SPI程序见【51单片机快速入门指南】5：软件SPI
SPI选择模式1或2均可，实测模式0也行。

oled.h中的OLED_BUFFER_MODE为0时为普通模式，RAM占用少
oled.h中的OLED_BUFFER_MODE为1时使用大小为1024的RAM作为显存，并使用连续写入的方法更新屏幕。
