compeletely compatible with Arduino and Raspberry Pi

             Module Pin Connections
Sensor module => Arduino Sensor module => Raspberry Pi
SCL --> A5 SCL --> SCL
SDA --> A4 SDA --> SDA
GNO --> GNO GNO --> GNO
IRQ --> D2 IRQ -->GPIO
VCC --> 5V VCC --> 3.3V
  • Enable I2C interface of Raspberry PI, can be configured via the raspi-config configuration tool or edit the file /boot/config.txt, add line:
 dtparam=i2c_arm=on 
  • Add I2C modules,edit /etc/modules file (command: sudo nano /etc/modules) , append the following lines:
 i2c-bcm2708
 i2c-dev
  • Installing the I2C library and tools
 sudo apt-get install i2c-tools python-smbus
  • Update software and install the RPI.GPIO library
 sudo apt-get update
 sudo apt-get install build-essential python-dev python-pip
 sudo pip install RPi.GPIO
  • Install graphic library
 sudo apt-get install python-imaging python-smbus
  • Download some software libraries, then run
 sudo apt-get install git
 git clone https://github.com/adafruit/Adafruit_Python_SSD1306.git
 cd Adafruit_Python_SSD1306
 sudo python setup.py install
  • Provide three samples (animate.py, image.py,shapes.py)
 cd Adafruit_Python_SSD1306
 sudo python shapes.py 

Note: when using the sensor base plate, OLED on the left and right side interfaces using the RST PIN isdifferent, around 25# and 24# respectively, modify the corresponding pin on the line, the default is the right
