welcome.py not displaying any output

[fmentiplay]

Hello Thank you for producing the Luma library. I am having a problem with the welcome.py script.

My Hardware/ Software setup is as follows........ Hardware: Raspberry Pi 3B V1.2 OS: Raspbian GNU/Linux 9 (stretch) Kernel: Linux raspberrypi 4.14.79-v7+ #1159 SMP Sun Nov 4 17:50:20 GMT 2018 armv7l GNU/Linux

I have a OLED 128x128 dislpay (with ssd1351 driver) connected as suggested at https://luma-oled.readthedocs.io/en/latest/hardware.html

I have cloned luma.oled, luma.docs, luma.examples

I have run most of the examples successfully BUT when I run welcome.py I get no display output.

This is the command I run.....

pi@raspberrypi:~/luma.examples/examples $ python3 welcome.py --display ssd1351 --interface spi --spi-port 0 --spi-device 0 --width 128 --height 128 --framebuffer=full_frame

This the output....

Version: luma.oled 3.1.0 (luma.core 1.8.3)
Display: ssd1351
Interface: spi
Dimensions: 128 x 128
------------------------------------------------------------

It doesn't give any errors BUT nothing is displayed on the OLED. Is it a font issue?

If I run this simple script it works fine.

from time import sleep from luma.core.interface.serial import spi from luma.core.render import canvas from luma.oled.device import ssd1351

from PIL import ImageFont

serial = spi(device=0, port=0) device = ssd1351(serial)

font = ImageFont.truetype("/home/pi/luma.examples/examples/fonts/pixelmix.ttf",12)

with canvas(device) as draw: draw.rectangle(device.bounding_box, outline="white", fill="green") draw.text((20,40), "Hello World", font=font, fill="white") draw.text((20,60), 'Cool Stuff', font=font, fill="white")

sleep(1000)

Any help with this issue would be greatly appreciated Thanks in advance

@fmentiplay can you remove the --framebuffer=full_frame option, it's the only difference I can see (besides the font change).
