1.arduino的OLED屏汉字显示

1. 字模显示原理及取模软件的使用

我们使用的OLED屏是由方形的发光点阵列组成的，分辨率为128x64。英文和数字最小可用8x8像素，汉字最小显示像素为16x16，通常为了显示效果，英文和数字通常使用8x16像素表示。要显示需要的字符只需对应点亮像素区域中对应的发光点即可。

 

字模一般都是通过取模软件生成的，接下来介绍「PCtoLCD」取模软件的使用：

1. Windows系统下双击启动软件，点击「模式」，选择「字符模式」，通常默认就是字符模式。

2. 点击「选项」进行字模配置。通常字模配置要根据程序驱动方式来选择，本篇中我们选择阴码、逐行式、顺向，其他选项如下图所示。

3. 输入汉字。点击生成字模或者保存字模，就会得到对应的点阵数据。

2. 实验材料

  • Uno R3开发板
  • 配套USB数据线
  • 面包板及配套连接线
  • OLED显示屏

3. 实验步骤

1. 根据原理图搭建电路图。

IIC接口只需要两根线。OLED屏的VCC和GND分别连接开发板的3.3V和GND，OLED屏的SDA和SCL分别连接开发板A4和A5。

实验原理图如下图所示：

2. 新建sketch，拷贝如下代码替换自动生成的代码并进行保存。
