PINE64 + mini OLED display + Luma.OLED = PINEimus Prime - sgjava - 04-19-2017

First there was CHIPtimus Prime for the CHIP SBC. Then came ODROIDtimus Prime for the ODROID C series. Now there's PINEimus Prime for the PINE64. This will work for I2C displays only at this point. I wasn't able to get SPI fired up with legacy or mainline Armbian.

Transform your PINE64 into a PINEimus Prime for projects requiring a small OLED display. Luma.OLED makes it easy to do text, graphics and video. Both displays I used to test I bought on Amazon. I already ordered some cheaper ones on EBay. I was able to get 3 SSD1306 I2C displays for under $10! I also ordered some TFT displays as well to test.

Requirements

PINE64 flashed with latest legacy Armbian Ubuntu server
Small nylon nuts, bolts and standoffs
OLED display (check http://luma-oled.readthedocs.io/en/latest/hardware.html)

Do the following for I2C version of SSD1306

Tested I2C OLED display (I used https://www.amazon.com/gp/product/B00O2KDQBE, but there are cheaper alternatives)
4 female/female jumper wires required

The 4 wire DIY display can be powered by 3.3V or 5V which makes it handy if you need the other power source for something else. Wire mapping using i2c-0 (twi0):

Code:
VCC to VCC 5V   (pin 4)
GND to GND      (pin 6)
SCL to I2C1 SCL (pin 5)
SDA to I2C1 SDA (pin 3)

Configure I2C

Power off PINE64, wire up display and power on
sudo apt-get install i2c-tools
sudo usermod -a -G i2c username

Test I2C and display

i2cdetect -l

Code:
i2c-0    i2c           twi0                                I2C adapter
i2c-1    i2c           twi1                                I2C adapter

i2cdetect -y 1

Code:
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f

Time to install Luma.OLED

Code:
sudo apt-get install python-dev python-pip libfreetype6-dev libjpeg-dev
sudo -H pip install --upgrade pip setuptools
sudo -H pip install --upgrade luma.oled

I2C hello world

cd
nano i2chello.py

Code:
import time
from luma.core.serial import i2c
from luma.core.render import canvas
from luma.oled.device import ssd1306

serial = i2c(port=1, address=0x3C)
device = ssd1306(serial)

with canvas(device) as draw:
    draw.rectangle(device.bounding_box, outline="white")
    draw.text((3, 3), "Hello", fill="white")

time.sleep(10)

python i2chello.py

Then install examples

Code:
cd
sudo apt-get install git-core libsdl-dev libportmidi-dev libsdl-ttf2.0-dev libsdl-mixer1.2-dev libsdl-image1.2-dev
git clone https://github.com/rm-hull/luma.examples.git
cd luma.examples
sudo -H pip install -e .

Run example on I2C display

Code:
cd
cd luma.examples
python examples/invaders.py -d ssd1306 --i2c-port 1 --i2c-address 0x3c

Thanks for the tutorial, I may have a project that requires a small display...

Now if I can only get SPI/GPIO working I could get the SPI displays fired up. I just got SPI/GPIO configured on the ODROID C1 using a RPi.GPIO replacement module. I need something similar for PINE64.

RE: PINE64 + mini OLED display + Luma.OLED = PINEimus Prime - dkryder - 04-20-2017

there is a rpi-gpio for pine64 around. at least there was a while back. https://github.com/swkim01/RPi.GPIO-PineA64 i think there were some issues with this in getting it to work as expected. it does not appear to be under active development currently.

RE: PINE64 + mini OLED display + Luma.OLED = PINEimus Prime - sgjava - 04-20-2017

Yea, I looked around, but without a stable GPIO module it's impossible to get Luma.OLED working. I have it working on CHIP and ODROID C1 with the mono display, but the RGB SSD1331 is still giving me issues. I ordered a Pi 3, so I can use that as a base test since that what most GPIO code is written for.
