OLED-SSD1306 Module

Introduction

SSD1306 is a single-chip CMOS OLED/PLED driver with controller for organic / polymer light emitting diode dot-matrix graphic display system. It consists of 128 segments and 64commons. This IC is designed for Common Cathode type OLED panel. The SSD1306 embeds with contrast control, display RAM and oscillator, which reduces the number of external components and power consumption. It has 256-step brightness control. It is suitable for many compact portable applications, such as Smart watch，eal-time image display of camera on smart car，Battery management device，etc.

Schematic

Features

• For OLED-SSD1306, a more elaborate and beautiful screen than LCD, with more functions

• High contrast, thus supporting clear display With no need of backlight

• Working voltage: 2.7V - 5.5V; PCB size: 2.8 x 3.2cm

• Standard double-sided printed circuit board, 1.16mm thick, with an elegant layout, 3-mm holes at two corners for easy fixing

• Low power consumption: 0.04W during normal operation

Test

To use the OLED with Arduino, you can take the following steps.

Step1:Connecting circuit

SSD1306 ------- Arduino Uno/Mega2560

GND --------- GND

VCC ------- 5V

SCL ------- A5 Uno/pin21 Mega2560

SDA ------- A4 Uno/pin20 Mega2560

Step2:Install the Arduino IDE in your computer.For detailed steps,refer to

http://wiki.sunfounder.cc/index.php?title=Install_Arduino_Software

Step3:Add U8glib library.

1) Through the links at the bottom of the page to download U8glib.zip and unzip.

2)the Arduino IDE, import the library from the "Add Library" Menu.

3) Find the u8glib folder you just extracted，clink open.

Step4：Open Graphics_Test.ino, Before clicking the Upload icon, set the Port and Board under Tools menu.Then upload the code to the board

===To use the OLED with Raspberry Pi, you can take the following steps. ===
Step1:Connecting circuit

SSD1306 ------- Raspberry Pi

Step2: Download

git clone https://github.com/adafruit/Adafruit_Python_SSD1306
Step3: Install
Go to the folder extracted from the package file downloaded:
cd Adafruit_Python_SSD1306
sudo python setup.py install

Step4:Edit the code

Go to the examples folder and you can see some example files inside. Let's take shapes.py for example.
cd examples/
nano shapes.py
Since we use the I2C interface, the lines for SPI interface need to be commented out.
Add a # to the beginning of the lines to do it.
Here comment out the Line 23 #import Adafruit_GPIO.SPI as SPI.

Press Ctrl+O to save, and Ctrl+X to exit.

Then run the program:
Python shapes.py
