ARDUINO UNO R3 SMD

1.SPI方式驱动
硬件依然借助的是MICOKIT的EXT板，库文件我是下载的Adafruit的，点击下载

Adafruit_SSD1306.rar (305.99 KB) ，还是将其解压到IDE安装路径下的library下

这里说明一下，该库默认是128*32的屏，需要手动修改Adafruit_SSD1306-master文件下的Adafruit_SSD1306.h，将pixel定义为128*64

编译运行ssd1306_128x64_spi该DEMO，部分截图显示如下:

2.I2C驱动，编译运行ssd1306_128x64_i2c该DEMO即可，该库IIC的引脚定义是A5是SCL，A4是SDA，然后还要注意的是IIC地址，有些是0x3C，有些是0x3D，按需修改就好。

编译运行，部分截图如下：

有库文件支持，还是非常方便的。

3.显示字符以及中文中文显示需要自己做字库，这里我用的16*16大小的。

字模提取V2.2.rar (256.55 KB)
打开软件，输入要显示的字符（不需要修改字体，不然像素点不好匹配），取模，生成即可，非常方便

我是基于IIC驱动的基础下做的，代码如下

复制

#include <SPI.h>  

#include <Wire.h>  

#include <Adafruit_GFX.h>  

#include <Adafruit_SSD1306.h>  

  

#define OLED_RESET 4  

Adafruit_SSD1306 display(OLED_RESET);  

  

#define **16_GLCD_HEIGHT 16 //定义显示高度  

#define **16_GLCD_WIDTH  16 //定义显示宽度
