OLED屏幕驱动

一、OLED简介

OLED是常见屏幕的一种。在我们平时制作电子产品的时候常常用来显示一些重要信息，也可以用于UI设计，设计显示精美的UI界面。

二、IIC通信

IIC是一种串行通信总线，使用多主从架构，IIC协议仅需要使用两个引脚，IIC一共有只有两个总线：一条是双向的串行数据线SDA，一条是串行时钟线SCL，所有接到I2C总线设备上的串行数据SDA都接到总线的SDA上，各设备的时钟线SCL接到总线的SCL上。IIC总线上的每个设备都自己一个唯一的地址，来确保不同设备之间访问的准确性。主机通过控制SDA线上高低电平的变化来传递信息。

三、AT32 IIC控制OLED实现

AT32具有一个IIC总线接口，支持七位寻址模式与十位寻址模式，标准模式下速度可达100khz，在高速模式下可以达到400khz。

（数据手册中的IIC部分说明）

程序实现

在实际程序方面，采用IO口模拟IIC方式，这是为了方便日后移植其他型号的AT32

只需在main.h文件中添加上OLED.h文件的位置即可使用OLED库

OLED初始化及代码测试


  OLED_Init();
  OLED_ShowString(1,1,"123");

四、实验效果
