使用Arduino驱动OLED显示屏：一个简单的指南

使用Arduino驱动SSD1306 OLED 显示屏工作

1、准备工作

1.1）Arduino中库的载入

#include <Adafruit_SSD1306.h>驱动128×64 and 128×32 的屏幕显示的库
#include <Adafruit_GFX.h>//Arduino的图形库
可以在arduino管理库中搜索下载，也可以自己下载库导入到arduino的libraries文件夹中。

1.2）接线

在这里使用的是arduino UNO开发板和OLED 0.96 IIC 128×64模块

Arduino SSD1306
3.3V VCC
GND GND
A4 SDA
A5 SCL

2、程序代码

2.1）文字取模

取模的软件使用的是太极创客给出的取模软件，页面如下

参数设置如网页设置即可。跳转太极创客Arduino驱动OLED屏幕

2.2）Arduino程序

#include <Adafruit_SSD1306.h>驱动128x64 and 128x32 的屏幕显示的库
#include <Adafruit_GFX.h>//Arduino的图形库
#include <Wire.h>
#include <SPI.h>

#define SCREEN_WIDTH 128 // OLED display width, in pixels
#define SCREEN_HEIGHT 64 // OLED display height, in pixels
// Declaration for an SSD1306 display connected to I2C (SDA, SCL pins)

#define OLED_RESET 4 // Reset pin # (or -1 if sharing Arduino reset pin)
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);

void setup()
{
  Serial.begin(9600);
  Serial.println("OLED FeatherWing test");//串口输出信息
  
  display.begin(SSD1306_SWITCHCAPVCC, 0x3c);//初始化OLED并设置其IIC地址为 0x3C
  display.clearDisplay();//清屏
  delay(200);

  display.setTextSize(1.3);
  display.setTextColor(SSD1306_WHITE);
  display.setCursor(0,0);//设置光标的位置

//绘制像素点
//  display.drawPixel(64, 32, WHITE);//(x坐标，y坐标，颜色)

//绘制水平线
//  display.drawFastHLine(64,32,64,SSD1306_WHITE);//(x起点，y起点，长度，颜色)
//绘制竖直线
// display.drawFastVLine(64,10,50,SSD1306_WHITE);

 //绘制线
// display.drawLine(0,0,128,64,SSD1306_WHITE);//（x起，y起，x终，y终）

//绘制空心矩形
// display.drawRect(0,0,128,64,SSD1306_WHITE);//(左上角x坐标，左上角y坐标，矩形长，矩形宽)

//绘制实心矩形
//display.fillRect(20,10,88,44,SSD1306_WHITE);//同上

//点亮全屏
//  display.fillScreen(SSD1306_WHITE);

//绘制空心圆
//display.drawCircle(64,32,32,SSD1306_WHITE);//(圆心x坐标，圆心y坐标，半径)

//绘制实心圆
//display.fillCircle(64,32,31,SSD1306_WHITE);

//绘制空心三角形
//display.drawTriangle(63,0, 0,63, 127,63, SSD1306_WHITE);//(第一顶点坐标[x,y]，第二，第三)

//绘制实心三角形
//display.fillTriangle(63,0, 0,63, 127,63, SSD1306_WHITE);

//绘制空心圆角矩形
//display.drawRoundRect(10,5,107, 43,8, SSD1306_WHITE);//(左上角x，左上角y，矩形长，矩形宽，矩形圆角半径)

//实心圆角
//display.fillRoundRect(10,5,107,53,3, SSD1306_WHITE);

//绘制Bitmap图像
//Bimap图像数据

3、效果展示



最后，给与图片取模时需要注意以下内容。
找到想要取模的图片，然后使用window自带的图画软件打开，修改好像素大小后，另存为BMP格式照片，然后在文件类型选择单色位图，如下图所示。这样的照片就可以使用取模软件成功取模啦！（本人苦苦使用ps，总是不成功都傻了，也不知道为什么不能用ps编辑图片）
