SSD1331 no display

[sgjava]

Using ODROID C1+ and the following works fine:

import time
from RPi import GPIO
from luma.core.interface.serial import spi
from luma.core.render import canvas
from luma.oled.device import ssd1331

GPIO.setmode(GPIO.BOARD)
GPIO.setwarnings(False)
serial = spi(port=0, device=0, gpio=GPIO, gpio_DC=18, gpio_RST=22)
device = ssd1331(serial)

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

time.sleep(10)

Running any of the examples with the following and nothing displays:

sudo python examples/invaders.py -d ssd1331 -i spi --spi-port 0 --spi-device 0 --gpio-data-command 18 --gpio-reset 22 --width 96 --height 64
Version: luma.oled 2.3.1 (luma.core 1.2.1)
Display: ssd1331
Interface: spi
Dimensions: 96 x 64

If you run the perfloop.py example, do you see the FPS being reported on the console?

Ok, so the reason the examples don't work for you is that when it initializes, it does so with BCM numbering rather than BOARD (like your working example does). See https://github.com/rm-hull/luma.core/blob/master/luma/core/lib.py#L24.

If odroid supports BCM pin numbers, try substituting the right values on the command line and it should work as expected.

OK, cool, I'l try BCM after looking at https://github.com/swkim01/RPi.GPIO-OdroidC1 and I'll reply back here...

Haha, you rock, Merry Xmas!
