OLED液晶屏幕（1）OLED液晶屏幕ssd1306驱动芯片 arduino运行 ESP8266-07可以 12f不可以

OLED屏幕有各种形状和尺寸，但目前有两种非常受欢迎的屏幕尺寸。

1）0.96“

2）1.3“

他们也有2种常见的颜色

1）蓝色

2）白色

驱动OLED的芯片常用的有两种。这两种芯片有许多非常相似的设置命令（在大多数情况下相同），但用于显示信息的命令集是不同的，所以你不能只是改变屏幕 - 你需要更改程序/库来适合相应的芯片！

1）SH1106

2）SSD1306

Arduino Uno OLED接线

下图显示了如何将Geekcreit 0.96英寸OLED I2C显示器连接到Arduino。用于将OLED显示器连接到Arduino Uno的引脚连接如下。

• OLED GND - Arduino GND
• OLED VCC - Arduino 5V
• OLED SCL - Arduino Uno A5
• OLED SDA - Arduino Uno A4

Arduino MEGA 2560 OLED接线

用于将Arduino MEGA 2560连接到OLED显示器的引脚连接如下。

• OLED GND - Arduino GND
• OLED VCC - Arduino 5V
• OLED SCL - Arduino MEGA 2560引脚21
• OLED SDA - Arduino MEGA 2560引脚20

 ESP8266-07 连线方式

VCC-5v

GND-GND

SCL-D1

SDA-D2

用于SSD1306和图形功能的ArduinoOLEDI²C库

必须安装两个Arduino库才能开始使用显示器。SSD1306驱动程序库用于初始化显示并提供低级显示功能。GFX库提供用于显示文本，绘图线和圆圈等的图形功能。这两个库都可以从Adafruit获得。

 

 

安装SSD1306驱动程序库

1手动安装。下载Adafruit_SSD1306库，该库将保存到您的计算机中，名为Adafruit_SSD1306-master.zip。

将Adafruit_SSD1306-master文件夹从下载的压缩文件复制到Arduino 库文件夹中。此文件夹通常位于Windows系统上的Documents→Arduino→库中。在Linux上，它通常位于主文件夹 →Arduino→库中。

最后在Arduino库文件夹中，将Adafruit_SSD1306-master文件夹重命名为Adafruit_SSD1306。

2自动安装

安装GFX库

下载Adafruit_GFX库，该库保存在您的计算机中，名为Adafruit-GFX-Library-master.zip。

将Adafruit-GFX-Library-master文件夹从下载的压缩文件复制到Arduino库文件夹，如上面的SSD1306驱动程序所做。

在Arduino库文件夹中，将Adafruit-GFX-Library-master文件夹重命名为Adafruit_GFX。

 使用

找到显示屏spi的地址，修改成 0x3C(源库代码打开可能是0x3D)

 

 源代码修改

开启 128*64的注释（ESP8266-07使用的是这个正常工作）

关闭源代码 128*32的注释（arduino mega 2560使用的是这个正常工作）

直接烧录

有报错
