先看效果怎么样：

OLED屏幕介绍：

OLED，即有机发光二极管OLED（Organic Light-Emitting Diode），又称为有机电激光显示（OrganicElectroluminesence Display, OELD）。因为具备轻薄、省电等特性，因此从2003年开始，这种显示设备在MP3播放器上得到了广泛应用，而对于同属数码类产品的DC 与手机，此前只是在一些展会上展示过采用OLED屏幕的工程样品，还并未走入实际应用的阶段。但OLED屏幕却具备了许多LCD不可比拟的优势，因此它也一直被业内人士所看好。目前常见的OLED模块是0.96英寸的显示屏，价格便宜，引脚少很方便使用，其采用的通讯方式常见为IIC和SPI协议，不过IIC的比较常见一些。

瑞萨RA8D1通过IIC总线控制0.96 OLED屏幕

第一步：新建项目工程后直接添加IIC驱动模块Stacks

配置相关IIC

配置IIC通讯引脚

第一步：添加库文件

添加图像库文件bmp文件

bmp.h文件
