OLED显示屏驱动HAL库 一、简介：
SSD1306 是一个单片 CMOS OLED/PLED 驱动芯片可以驱动有机/聚合发光二极管点阵图形显示系统。由 128 segments 和 64 Commons 组成。该芯片专为共阴极 OLED 面板设计。
SSD1306 中嵌入了对比度控制器、显示 RAM 和晶振，并因此减少了外部器件和功耗。有 256级亮度控制。数据/命令的发送有三种接口可选择：6800/8000 串口，I2C 接口或 SPI 接口。
适用于多数简介的应用，注入移动电话的屏显，MP3 播放器和计算器等。

0.96寸oled显示屏有4引脚的7引脚的，4引脚的只能采用i2c驱动，7引脚的是既可以使用i2c也可以使用spi驱动的。

本次实验采用的是第一种，I2C驱动的，I2C的原理我就不做介绍了，大家可以自己去看一下。
如果大家详细看了工作原理那个链接的文件，会发现这个显示屏驱动有三种寻址方式，水平寻址、垂直寻址还有页寻址方式。下面给大家介绍的代码驱动就是采用的页寻址方式。
二、驱动的引脚配置
主控芯片使用STM32F103C8T6,这款芯片有两个I2C，I2C1和I2C2，因为I2C2与USART3用的相同的引脚，单独做oled显示实验的时候不需要考虑，但是在需要用到USART3的时候就不建议使用I2C2，我这里还是使用I2C1也就是PB6（SCL）和PB7(SDA)，直接和oled显示屏上相连。
因为使用HAL库，所以我这里直接使用STM32CubeMax进行配置：
配置如下：

配置完了，直接命名生成代码。
生成后的代码：

到这里工程的创建基本完成，接下来说说OLED驱动代码部分。
