SCL-A4

SDA-A5

案例

使用arduino控制oled屏幕循环轮播显示两种不同的“续加仪”字样。

库使用

需要使用到已有库Wire、Adafruit_GFX、Adafruit_SSD1306，可直接在arduino中搜素安装

基本的用法如下：

//引入IIC通讯所需的Wire库文件

#include

// 引入驱动OLED0.96所需的库

#include

#include

// 参数依次为：屏幕像素宽、高、Wire对象、重置引脚

Adafruit_SSD1306 display(128, 64, &Wire, 4);

// 初始化OLED并设置其IIC地址为 0x3C

display.begin(SSD1306_SWITCHCAPVCC, 0x3C);

//设置光标位置

display.setCursor(0, 0);

//输出文字(西文);

display.print("hello Xujiayi!");

//显示

display.display();

自定义图形/文字输出：

static const unsigned char PROGMEM xu[] = {

0x00,0x00,0x00,0x00,0x00,0x00,0x10,0x00,0x01,0x00,0x1C,0x00,0x03,0x80,0x18,0x00,

// 显示文字 (左上x坐标,右上y坐标, 图形数组, 图形像素点宽、高, 颜色)

display.drawBitmap(0, 0, xu, 32, 32, 1);

其中图形数组的获取方法见下文。

取模

使用pctolcd软件即可完成:

然后复制数据作为数组数据即可
