一、0.96 IIC OLED介绍

OLED是一种利用多层有机薄膜结构产生电致发光的器件，它很容易制作，而且只需要低的驱动电压，这些主要的特征使得OLED在满足平面显示器的应用上显得非常突出。OLED显示屏比LCD更轻薄、亮度高、功耗低、响应快、清晰度高、柔性好、发光效率高，能满足消费者对显示技术的新需求。

我们最常用的OLED 0.96 IIC 128×64模块，如下所示：


其中：

• 0.96：指的是屏幕的显示尺寸0.96inch；
• 128×64：指的是屏幕的分辨率为128×64；
• IIC：指的是该模块使用IIC协议进行通讯；

双色OLED
除了单色OLED，还有双色OLED，例如：黄蓝屏，即屏上1/4部分为黄色，屏下3/4为蓝色；而且是固定区域显示固定颜色，颜色和显示区域均不能修改。

---

显示原理

• OLED的显存分布情况，可以理解为：水平方向分布了128个像素点，垂直方向分布了64个像素点；
• 而驱动芯片在点亮像素点的时候，是以8个像素点为单位的；
• 官方的例程推荐的是垂直扫描的方式，也就是先画垂直方向的8个像素点；
• 所以我们在画点的时候Y的取值为0-7，X的取值为0-127；

//存放格式如下.
//[0]0 1 2 3 ... 127    
//[1]0 1 2 3 ... 127    
//[2]0 1 2 3 ... 127    
//[3]0 1 2 3 ... 127    
//[4]0 1 2 3 ... 127    
//[5]0 1 2 3 ... 127    
//[6]0 1 2 3 ... 127    
//[7]0 1 2 3 ... 127

二、安装库文件

我们需要使用esp8266-oled-ssd1306库来实现控制OLED，Arduino安装操作如下所示：

---

2.1、库屏幕控制相关API

1、引入库(我的是IIC接口)

#include "SSD1306Wire.h"

---

2、实例化一个SSD1306Wire对象

SSD1306Wire display(0x3c, 4, 5);

---

3、初始化屏幕

display.init();

---

4、清除

display.clear();

---

5、清除某个点

void OLEDDisplay::clearPixel(int16_t x, int16_t y)

display.clearPixel(0,0);

---

6、显示buf区的内容

void SSD1306Wire::display()

display.display();

---

7、把显示屏关掉

display.displayOff();

---

8、把显示屏打开

display.displayOn();

---

9、深度睡眠后恢复

display.allocateBuffer();

---

10、关闭OLED，清除对象和缓存

void OLEDDisplay::end()

display.end();

---

11、屏幕垂直翻转

display.flipScreenVertically();

---

12、屏幕镜像显示

display.mirrorScreen();

---

13、反色显示

display.invertDisplay();

---

14、回归正常显示

display.normalDisplay();

---

15、重新初始化

display.resetDisplay();

---

16、重置显示方向

display.resetOrientation();

---

17、设置显示亮度

void OLEDDisplay::setBrightness(uint8_t)

display.setContrast(255);

---

18、设置对比度

void OLEDDisplay::setContrast(uint8_t contrast, uint8_t precharge = (uint8_t)'�', uint8_t comdetect = (uint8_t)'@')

例如: 极低的亮度和对比度：对比度= 10，预充电precharge= 5，comdetect = 0
正常亮度和对比度：对比度= 100

---

2.2、库绘制相关API

1、设置一个点

void OLEDDisplay::setPixel(int16_t x, int16_t y)

---

2、画空心圆

void OLEDDisplay::drawCircle(int16_t x, int16_t y, int16_t radius)

display.drawCircle(64,32,20);

---

3、画实心圆

void OLEDDisplay::fillCircle(int16_t x, int16_t y, int16_t radius)

---

4、画1/4圆弧

void OLEDDisplay::drawCircleQuads(int16_t x0, int16_t y0, int16_t radius, uint8_t quads)

display.drawCircleQuads(32,32,20,1);

其中: quads是角度

quads	左上	右上	左下	右下
0
1		✔
2	✔
3	✔	✔
4			✔
5		✔	✔
6	✔		✔

15	✔	✔	✔	✔

---

5、画水平线

void OLEDDisplay::drawHorizontalLine(int16_t x, int16_t y, int16_t length)

---

6、画垂直线

void OLEDDisplay::drawVerticalLine(int16_t x, int16_t y, int16_t length)

---

7、画线

void OLEDDisplay::drawLine(int16_t x0, int16_t y0, int16_t x1, int16_t y1)

---

8、画空心矩形

void OLEDDisplay::drawRect(int16_t x, int16_t y, int16_t width, int16_t height)

---

9、画实心矩形

void OLEDDisplay::fillRect(int16_t x, int16_t y, int16_t width, int16_t height)

---

10、画进度条

void OLEDDisplay::drawProgressBar(uint16_t x, uint16_t y, uint16_t width, uint16_t height, uint8_t progress)

---

2.3、文本相关API

1、设置字体

void OLEDDisplay::setFont(const uint8_t *fontData)

内建字体	字高	字宽	包含字符
ArialMT_Plain_10	13	10	224个字符
ArialMT_Plain_16	19	16	224个字符
ArialMT_Plain_24	28	24	224个字符

---

2、设置文本对齐方法

void OLEDDisplay::setTextAlignment(OLEDDISPLAY_TEXT_ALIGNMENT textAlignment)

对齐方法	描述
TEXT_ALIGN_LEFT	左对齐
TEXT_ALIGN_RIGHT	右对齐
TEXT_ALIGN_CENTER	居中对齐
TEXT_ALIGN_CENTER_BOTH	上下左右对齐

---

3、绘制字符串

void OLEDDisplay::drawString(int16_t x, int16_t y, String text)

display.clear();
display.setFont(ArialMT_Plain_16);
display.drawString(0,0,"hello");
display.display();

---

4、绘制字符串(带最大宽度)

display.drawStringMaxWidth(int16_t x, int16_t y, String text)

到达最大宽度回换行显示

---

2.4、图像相关API

1、显示16*16的图标

void OLEDDisplay::drawIco16x16(int16_t x, int16_t y, const char *ico, bool inverse = false)

新建16x16的图像

绘制图像

字模设置输出格式

生成字模

#include "SSD1306Wire.h"
 
SSD1306Wire display(0x3c, 21, 22);
 
const char image[] = {
    0x00,0x00,0x00,0x00,0x00,0x00,0x30,0x0C,0x78,0x0E,0x48,0x0A,0x00,0x00,0x00,0x00,

};
 
void setup()
{
  Serial.begin(115200);
  display.init();
  display.flipScreenVertically();
  display.clear();
  display.drawIco16x16(0, 0, image, 0);
  display.display();
}
 
void loop()
{
}

---

2、显示XBM图像

void OLEDDisplay::drawXbm(int16_t x, int16_t y, int16_t width, int16_t height, const uint8_t *xbm)

xbm图像可使用在线转换器：https://convertio.co/zh/

---

3、显示BMP位图图像

void OLEDDisplay::drawFastImage(int16_t x, int16_t y, int16_t width, int16_t height, const uint8_t *image)

---

三、显示字母

/*
 * ESP8266-NodeMCU通过驱动oled显示文文字和图片
 * 需要使用Arduino-OLED第三方库：https://github.com/ThingPulse/esp8266-oled-ssd1306/tree/4.2.0
 */

/* 使用0.96寸的OLED屏幕需要使用包含这个头文件 */
#include "SSD1306Wire.h"

/* 设置oled屏幕的相关信息 */
const int I2C_ADDR = 0x3c;              // oled屏幕的I2c地址
#define SDA_PIN 4                       // SDA引脚，默认gpio4(D2)
#define SCL_PIN 5                       // SCL引脚，默认gpio5(D1)

/* 新建一个oled屏幕对象，需要输入IIC地址，SDA和SCL引脚号 */
SSD1306Wire oled(I2C_ADDR, SDA_PIN, SCL_PIN);

void setup() {
  /* 1. 初始化串口通讯波特率为115200*/
  Serial.begin(115200);

  /* 2. oled屏幕初始化 */
  oled.init();
  oled.flipScreenVertically();        // 设置屏幕翻转
  oled.setContrast(255);              // 设置屏幕亮度
  drawRect();                         // 测试屏幕显示
  oled.clear(); oled.display();       // 清除屏幕
}

void loop() {
  oled.setFont(ArialMT_Plain_24);     // 设置字体
  oled.drawString(0, 0, "HelloWorld!");     // 将要显示的文字写入缓存
  oled.display();                     // 将缓存里的文字在屏幕上显示
}

void drawRect(void) {
  for (int16_t i=0; i<oled.getHeight()/2; i+=2) {
    oled.drawRect(i, i, oled.getWidth()-2*i, oled.getHeight()-2*i);
    oled.display();
    delay(50);
  }
}

---

四、显示汉字

显示汉字要先进行取模了，我们选择列行式的取模方式，如下图所示：

取模软件分享：
链接：https://pan.baidu.com/s/12x-e09uORupj07MNS00C5A
提取码：fkp4

点击【模式】–>【字符模式】–>【选项】，或者齿轮，如下设置

点击确定后，就可以输入文字了

点击生成字模，可以看到生成了如下：

 你(0) 好(1) 世(2) 界(3)
{
{0x00,0x00,0x00,0x00,0x04,0x00,0x00,0x03,0x00,0x80,0x00,0x00,0xE0,0xFF,0x07,0x1C,0x00,0x00,0x06,0x00,0x01,0x00,0xC1,0x00,0x80,0x30,0x00,0x70,0x0C,0x00,0x3E,0x04,0x02,0x24,0x00,0x06,0xA0,0xFF,0x07,0xA0,0x00,0x00,0x20,0x00,0x00,0x20,0x04,0x00,0xA0,0x18,0x00,0x60,0x70,0x00,0x00,0xC0,0x00,0x00,0x00,0x00},/*"你",0*/
{0x00,0x00,0x00,0x00,0x00,0x04,0x20,0x10,0x02,0x20,0x2F,0x01,0xFC,0xA0,0x00,0x26,0x40,0x00,0x20,0x7C,0x00,0xE0,0xC7,0x00,0x20,0x82,0x01,0x00,0x02,0x00,0x04,0x02,0x00,0x04,0x02,0x02,0x04,0x02,0x06,0xC4,0xFF,0x03,0x64,0x02,0x00,0x18,0x02,0x00,0x0C,0x02,0x00,0x00,0x02,0x00,0x00,0x02,0x00,0x00,0x00,0x00},/*"好",1*/
{0x00,0x00,0x00,0x00,0x00,0x00,0x80,0x00,0x00,0x80,0x00,0x00,0xF8,0xFF,0x07,0x80,0x00,0x02,0x80,0x00,0x02,0x80,0x00,0x02,0xFE,0xFF,0x02,0xFC,0x7F,0x02,0x80,0x20,0x02,0x80,0x20,0x02,0x80,0x20,0x02,0x80,0x20,0x02,0xFE,0x7F,0x02,0x80,0x00,0x02,0x80,0x00,0x02,0xC0,0x00,0x03,0x80,0x00,0x02,0x00,0x00,0x00},/*"世",2*/
{0x00,0x00,0x00,0x00,0x20,0x00,0x00,0x20,0x00,0x00,0x10,0x04,0xFE,0x11,0x02,0x92,0x08,0x02,0x92,0x88,0x01,0x92,0xFC,0x00,0x12,0x1B,0x00,0x12,0x01,0x00,0xFC,0x00,0x00,0x12,0x01,0x00,0x92,0xFA,0x07,0x92,0x0C,0x00,0x92,0x0C,0x00,0xFE,0x08,0x00,0x00,0x18,0x00,0x00,0x18,0x00,0x00,0x00,0x00,0x00,0x00,0x00},/*"界",3*/
}

然后我们将生成的字模复制到代码中的数组中：
