Arduino控制oled屏幕显示自定义字体文字
oled屏幕
连接线路
Oled-Arduino：
GND-GND
VCC-3v3
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 <Wire>
// 引入驱动OLED0.96所需的库
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>
// 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();
C++自定义图形/文字输出：

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);
C++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
