基于arduino的oled显示屏的使用

摘要

​ OLED属于一种电流型的有机发光器件，是通过载流子的注入和复合而致发光的现象，发光强度与注入的电流成正比。OLED在电场的作用下，阳极产生的空穴和阴极产生的电子就会发生移动，分别向空穴传输层和电子传输层注入，迁移到发光层。当二者在发光层相遇时，产生能量激子，从而激发发光分子最终产生可见光。

oled显示屏模块是每个Maker都会用到的显示器件，然而OLED本身它是使用在我们生活中很多地方的。我们这里所说的就是OLED显示屏模块，它有双色和单色的，有128X64的，有128X32等不同规格。我们这里讲的是基于arduino的OLED库的基本的调用。

1.依赖的库

Adafruit_GFX.h

Adafruit_SSD1306.h

​ 如果使用的OLED模块是128X64像素，需要修改Adafruit_SSD1306.h头文件。具体操作：找到Adafruit_SSD1306.h文件并打开！
PS:头文件不能直接使用arduino ide打开，需要使用文本编辑器打开，文本编辑器牵扯到文本编码，推荐使用editplus 或者Notepad进行修改。如果使用的是Visual studio，打开头文件就不需要找路径，选中直接右键选择打开头文件就好了。
​ 取消注释: #define SSD1306_128_64
​ 注释掉行：#define SSD1306_128_32

2.库函数简介

​ Adafruit_SSD1306.h是基于Adafruit_GFX.h开发的库，扩展重写了一些方法，在使用中，我们主要使用部分函数来实现基础的使用，其中有两个库的函数方法，主要介绍的函数如下：

display();//显示缓冲区图片
clearDisplay();//清理缓冲区`drawPixel(X_POS, Y_POS, WHITE);  // 画点
drawLine(X_POS, Y_POS,128, 64, WHITE);//画线
drawRect(X_POS, Y_POS, width, height , WHITE); // 画一个矩形
fillRect(X_POS, Y_POS, width, height, WHITE); // 画一个填充矩形
drawCircle(X_POS, Y_POS, 10, WHITE); // 画一个居中半径为10的圆
fillCircle(X_POS, Y_POS, 10, WHITE);// 画一个居中半径为10的填充圆
fillRoundRect(X_POS, Y_POS, width, height, 14, WHITE);// 画一个带半径14圆角的填充矩形startscrollright(0x00, 0x0f);//屏幕旋转
stopscroll();//屏幕旋转停止setTextSize(1);//设定字体大小
setTextColor(WHITE);//设定字体颜色
setCursor(0, 0);//设定起始点
write(i);//字符显示，asii对应的字符
println("Hello, world!"); // 文本显示drawBitmap(0, 0, logo_glcd_bmp_expendables[], HEIGHT, WIDTH, WHITE); // 显示一张图片invertDisplay(true); // 图形取反
invertDisplay(false);// 取消图形取反

3.硬件介绍

​ OLED模块是通过i2c与Arduino进行通讯的

//Arduino UNO--OLED
//VCC --3.3v  接3.3v电源
//GND--GND接地（GND）
//SCL--A5时钟线
//SDA--A4数据线

4.显示的基本操作

​ step i.显示内容更新到缓冲区

​ step ii.调用display()方法显示

​ step iii.清理缓存（在不清理缓冲区的情况下写入，如果不是写整个屏幕，写的位置与原有缓冲区数据与运算，会出现图像叠加，除非你特此设计）

5.示例

i.制作一个进度条

void Draw_Init_Interface(void) {for (size_t i = 0; i < 46; i = i + 5){display.clearDisplay();display.setTextSize(1);display.setTextColor(WHITE);display.setCursor(25, 20);display.println("Initialize...");display.drawRect(38, 38, 51, 6, WHITE);//以（38，38）为起点绘制一个长度51宽度为6的矩形display.drawLine(40, 40, 40 + i, 40, WHITE);//循环绘制线条达到显示进度的效果display.drawLine(40, 41, 40 + i, 41, WHITE);display.display();//delay(10);display.clearDisplay();}`display.display();
}

ii.显示文字

//显示字符，转换为ASCIIdisplay.setCursor(0,0);display.setTextSize(1);display.setTextColor(WHITE);for (uint8_t i=0; i < 168; i++) {if (i == '\n') continue;display.write(i);if ((i > 0) && (i % 21 == 0))display.println();}    display.display();// 显示字符串display.setTextSize(1);display.setTextColor(WHITE);display.setCursor(0,0);display.println("Hello, world!");display.setTextSize(2);display.println("Hello, world!");display.display();`delay(2000);`

iii.显示图片(中文）

// 显示一张图片
display.clearDisplay();
display.drawBitmap(0, 0, logo_glcd_bmp_expendables, LOGO_GLCD_HEIGHT, LOGO_GLCD_WIDTH, WHITE);
display.display();
delay(2000);
display.clearDisplay();

6.取模工具的使用

​ i.图片取模

​ ii.字符取模

图片和字符的取模请大家自行百度，这里免费为大家提供2款取模工具，需要的关注公众号“痴人听梦”

后台回复“取模工具”获取下载地址。

7.预设画面

​ 实例创建后，调用begin方法启动器件，在begin方法中默认会写入splash图像，作为启动画面。


此方法的具体代码：

if(HEIGHT > 32) {drawBitmap((WIDTH - splash1_width) / 2, (HEIGHT - splash1_height) / 2,splash1_data, splash1_width, splash1_height, 1);} else {drawBitmap((WIDTH - splash2_width) / 2, (HEIGHT - splash2_height) / 2,splash2_data, splash2_width, splash2_height, 1);}

​ 在使用Adafruit_SSD1306库进行OLED使用的时候，可以自己设计好自己的预设画面，更新到splash.h头文件中，替换掉其中的splash1_data[]，就可以将自己的预设画面作为启动画面了。需要注意的就是图画的长宽。库预设的是82X64的，如果你自己设计的是128X64的，也要记得改splash1_width和splash1_height这两个宏定义。

完整示例代码如下：
