mCookie-OLED is based on SSD1306 0.96-inch 128*64 OLED display module, adopting the IIC (I2C) interface and communicating with the a core module by connecting to an IIC interface on mCookie-Hub or stacked directly on an mCookie stack.
Features
- Single color (white) on a back background OLED display.
- No back-light needed as OLED is view-able in dark conditions.
- Low voltage and power consumption;
- Communication over I2C to save IO interfaces.
- Small, cheap, stackable and open.
Specification
- Resolution: 128x64;
- Size of the screen: 0.96 cun;
- Interface: IIC communication;
- Voltage: 3.3V.

Development
For the development, it need to be supported by _01_Microduino_OLED_U8glib library and check the library file here:
(Installation Address)\Microduino-IDE\hardware\Microduino\avr\libraries
- Open IDE and find "_01_Microduino_OLED_U8glib " examples under " File->Examples ".
 _01_Microduino_OLED_U8glib Project
u8glib Library Program Examples
- Open Arduino IDE, click "HelloWorld"under " File->Examples->_01_Microduino_OLED_U8glib " and open program examples.
- Download after compiling and you'll see "HelloWorld!" on the screen.
- Display character/variable:
- Use u8g.print(xx) function just the same way like Serial.print(xx).
- Change font:
- Use u8g.setFont (xx) function to change the font, parentheses "xx" can be replaced by the corresponding font library name (you can search font library in u8g.h within U8glib \utility folder);
- Large font is recommended for u8g_font_7x13, middle font for u8g_font_fixed_v0r and small font for u8g_font_chikitar;
- Change coordinates:
- Use u8g.setPrintPos (x, y) function to change the display of coordinates
- Screen Rotation：
- Post u8g.setRot180() in void setup() function, the screen will be flipped to 180-degree, you also can change 180 to 90,270;
Users can open other program examples and see the result.
