Introduction

LED 128×64 Display module is an OLED monochrome 128×64dot matrix display module with Grove 4pin I2C Interface.Comparing to LCD, OLED screens are way more competitive, which has a number of advantages such as high brightness, self-emission, high contrast ratio, slim / thin outline, wide viewing angle, wide temperature range, and low power consumption. It has bigger screen so that it can display more contents than the OLED 96×96.
Model:OLE35046P

Features

  • Grove compatible interface
  • Communicate Mode:I2C
  • Low power consumption
  • Display Color: White
  • Wide range of operating temperature:-20℃~70℃

Cautions

Please notice: heavy impact or stress on the OLED will cause the breakdown of screen..

Usage

With Arduino

The OLED128*64 uses all the pins of SSD1308 chip, the default original point is on the top left corner. You can also change the original point by adjusting the program and in order to display your desired patterns. For more details, please consult File:SSD1308_1.0.pdf and File:LY190-128064.pdf.

Here we demonstrate how to display "Seeedstudio" on the screen.

  • Plug the Grove - OLED Display 128*64 onto the I2C port on Grove - Base Shield, and then plug the Base Shield onto Arduino;


Grove-OLED Display 128X64.jpg

  • Download the library File:OLED_Display128X64 Library;
  • Unzip it into the libraries file of Arduino IDE by the path: ..\arduino-1.0\libraries.
  • Open the code directly by the path: File -> Example ->OLED_Display12864->OLED_Bitmap_Inverse_Display.

Note:This module is similar to Grove - OLED Display 96*96 in its usage and some library functions, you can make an gray 128*64 image arbitrary that can be shown on OLED 128*64. Please consult the latter one's Usage part of WIKI page for detailed instructions.

With Beaglebone Green

To begin editing programs that live on BBG, you can use the Cloud9 IDE.
As a simple exercise to become familiar with Cloud9 IDE, creating a simple application to blink one of the 4 user programmable LEDs on the BeagleBone is a good start.

If this is your first time to use Cloud9 IDE, please follow this link.

Step3: Save the file by clicking the disk icon with with the .py extension.

Step4: Connect Grove - OLED to Grove I2C socket on BBG.

Step5: Run the code. You'll find that the Grove - OLED outputs "Hello World".
