关于Arduino&SSD1306OLED（IIC）显示的学习
1、 前期准备
- arduino UNO开发板
- OLED 显示屏
- 导线若干
- 取模软件zimoV2.2
这里推荐一个在线图片取模软件
http://tools.clz.me/
2、引脚接线
OLED 显示屏有四个引脚，分别是：
SDA(数据线) SCK(时钟线) VDD(3.3V) GND
在UNO开发板上I2C接口，SDA对应D4，SCK对应D5
在MEGA2560开发板上I2C接口,SDA对应D20, SCL对应D21
3、通信地址
背面图：
模块背面的IIC ADRESSSELECT表示该模块在IIC通信作为从机时的地址，当中间的脚用电阻和左边接起来时，地址为0x78，当和右边接起来时，地址为0x7A。
这款屏幕尺寸约为0.96英寸，由SSD1306驱动，驱动接口I2C，I2C地址(0x3c 默认/0x3d)。
不同型号有不同的通信地址，可通过程序查询：
#include
void setup(){
Wire.begin();
Serial.begin(9600);
Serial.println("\nI2C Scanner");
}
void loop(){
byte error, address;
int nDevices;
Serial.println("Scanning...");
nDevices = 0;
for (address = 1; address < 127; address++ ){
// The i2c_scanner uses the return value of
// the Write.endTransmisstion to see if
// a device did acknowledge to the address.
Wire.beginTransmission(address);
error = Wire.endTransmission();
if (error == 0){
Serial.print("I2C device found at address 0x");
if (address < 16)
Serial.print("0");
Serial.print(address, HEX);
Serial.println(" !");
nDevices++;
}else if (error == 4){
Serial.print("Unknow error at address 0x");
if (address < 16)
Serial.print("0");
Serial.println(address, HEX);
}
}
if (nDevices == 0)
Serial.println("No I2C devices found\n");
else
Serial.println("done\n");
delay(5000); // wait 5 seconds for next scan
}
上传到arduino板上，打开串口可查看地址
4、编程与程序解读
注：编程之前需要添加Adafruit_SSD1306和Adafruit_GFX这两个库文件
官方例程：

关于显示，首先要建立坐标概念
这种型号的OLED 显示屏就是一个128(width)X64(height)点阵。在坐标系中，左上角是原点，X轴水平向右数值增加，Y轴竖直向下数值增大。
1.begin()
初始化I2C地址，在Arduino setup调用。
2.clearDisplay()
把Buffer缓存区清零，清除屏幕显示的东西，消影
3.display()
把Buffer缓存区的数据显示到屏幕上，任意一个需要显示的操作都需要调用这个方法
4.drawPixel(int16_t x, int16_t y, uint16_t color)
画点 点坐标 (x,y) (x,y,color)
5.drawLine(int16_t x0, int16_t y0, int16_t x1, int16_t y1, uint16_t color)
画线 从(x0,y0)到(x1,y1) （x0,y0,x1,y1,color）
6.drawRect(int16_t x, int16_t y, int16_t w, int16_t h, uint16_t color)
画空心矩形 左上角坐标(x0,y0) 宽度w 高度h (x0,y0,w,h,color)
7.fillRect(int16_t x, int16_t y, int16_t w, int16_t h, uint16_t color)
画实心矩形 左上角坐标(x0,y0) 宽度w 高度h (x0,y0,w,h,color)
8.drawCircle(int16_t x0, int16_t y0, int16_t r, uint16_t color)
画空心圆,圆心(x0,y0),半径 r (x0,y0,r,color)
9.fillCircle(int16_t x0, int16_t y0, int16_t r, uint16_t color)
画实心圆,圆心(x0,y0),半径 r (x0,y0,r,color)
10.drawTriangle(int16_t x0, int16_t y0, int16_t x1, int16_t y1, int16_t x2, int16_t y2, uint16_t color)
画空心三角形,上顶点坐标(x0,y0),左顶点坐标(x1,y1),右顶点坐标(x2,y2)
(x0,y0,x1,y1,x2,y2,color)
11.fillTriangle(int16_t x0, int16_t y0, int16_t x1, int16_t y1, int16_t x2, int16_t y2, uint16_t color)
画实心三角形,上顶点坐标(x0,y0),左顶点坐标(x1,y1),右顶点坐标(x2,y2)
（x0,y0,x1,y1,x2,y2,color）
12.drawRoundRect(int16_t x0, int16_t y0, int16_t w, int16_t h,int16_t radius, uint16_t color)
画空心圆角矩形,左上角坐标(x0,y0) 宽度w 高度h,圆角半径 radius
(x0,y0,w,h,radius,color)
13.fillRoundRect(int16_t x0, int16_t y0, int16_t w, int16_t h,int16_t radius, uint16_t color)
画实心圆角矩形,左上角坐标(x0,y0) 宽度w 高度h,圆角半径 radius
/*14.drawBitmap(int16_t x, int16_t y, const uint8_t *bitmap,int16_t w, int16_t h, uint16_t color)
画任意图形，左上角坐标(x,y)，图形数据 bitmap，图形高度h 宽度w
图形以点阵的显示形式生成代码，bitmap可以是真正图片的数据，也可以是单个文字的字模。
15.ShowCN_16(int16_t x, int16_t y, const uint8_t *bitmap,uint8_t size,uint16_t color)
显示一行文字(16X16字模)，左上角坐标(x,y),字模bitmap，字数size */
至于图片的静态和动态显示问题，在稍后学习之后再做更新
文字的显示
- 单文字显示
文字的显示需要运用取模软件取模，这里用的是zimoV2.2
打开软件
以文字“一”为例
新建一个16*16的像素块
在文字区输入 汉字“一”， Ctrl+回车生成文字，
在取模方式项选择C51格式生成代码
复制代码代码添加到下面程序中
#include
#include
#include
#define OLED_RESET 4
Adafruit_SSD1306 display(OLED_RESET);
#define NUMFLAKES 10
#define XPOS 0
#define YPOS 1
#define DELTAY 2
#define LOGO16_GLCD_HEIGHT 16
#define LOGO16_GLCD_WIDTH 16
#if (SSD1306_LCDHEIGHT != 64)
#error("Height incorrect, please fix Adafruit_SSD1306.h!");
#endif
/*-----显示文字一，把代码放入数组中---*/
static const uint8_t PROGMEM Strong_16x16[] = {
0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,
0x00,0x0C,0x00,0x0E,0xFF,0xFF,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,
0x00,0x00,0x00,0x00,0x00,0x00,
};
void setup() {
Serial.begin(9600);
delay(500);
// by default, we'll generate the high voltage from the 3.3v line internally! (neat!)
display.begin(SSD1306_SWITCHCAPVCC, 0x3C); // initialize with the I2C addr 0x3D (for the 128x64)
}
void loop() {
test_SSD1306();
}
void test_SSD1306(void){
display.clearDisplay(); // clears the screen and buffer
display.drawBitmap(16,16,Strong_16x16,16,16,WHITE); //(16,16)起点坐标，
display.display();
delay(2000);
}
其中display.drawBitmap(16,16,Strong_16x16,16,16,WHITE);
括号里面存放的依次是 起点坐标（16，16），Strong_16x16，显示区域大小（16 * 16），颜色
起点为（0,0）
起点为（16,16）
显示区域为（32,16）
显示区域为（128,64），实际为一堆乱码
关于其他文字显示出错的问题，原因是取模软件取模不正确需要在参数设置里面修改
观察显示的文字大小是否为16*16，如果不是，选择‘文字输入区字体选择’更改字体
如果还有问题点击 其它选项更改取模方式
这样基本上就能解决显示出错的问题。
- 多字显示
多字显示跟单字显示类似，用取模软件分别提取出文字的代码

显示效果
图片的显示
图片的显示与文字显示基本相同，具体步骤如下：
-
选择显示的图片
-
将图片的大小和格式更改为128*64，单色
-
打开取模软件，选择
打开图片，然后生成代码
