BPI 0.96’ OLED Display Module
![](BPI-OLED 1.jpg)
Contents
Description
Banana Pi 0.96’ OLED display module is designed by 52pi which is made by 128x64 yellow and blue OLED pixels , diagonal is only 0.96 inch . The controller is SSD1306, communicates via 4-wire SPI, the display have its own backlight, no backlight LED is required ,This reduces the power required to run the OLED and is why the display has such high contrast , extremely wide viewing angle and extremely operating temperature

How to use
Test OLED module on BPI-M3
![](OLED on bpi m3.jpg)
image: BPI-M3 Ubuntu15.10 (Kernel3.4)
Version: 1.0 HDMI
Step 1:
Version V1.0 doesn't include SPI Function. The boot.fex should be recompiled. Open SPI function
( https://github.com/BPI-SINOVOIP/BPI-M3-bsp/commit/62ff19944249b7a9efdee53f7760cb446c8984d9 )
Version V2.0 is going to support the spi-function by default.
Step 2 : Copy smaple code to OLED.c file
$ sudo vi OLED.c
Step 3 : Compile OLED.c
$ gcc -o OLED OLED.c -l wiringPi
Step 4 : Run OLED
$ sudo ./OLED
