Can not Modify Display Setting + Rotate Screen #111

Closed sanwaldx6x closed 3 years ago

sanwaldx6x commented 3 years ago

Hello I need help!

I try to modify the Pages Files, since a few days. But everything I change, will not change in the Display.

I modify the Page Files in /home/volumio/pydPiper-0.3-alpha I modify the Files pages_lcd_20x4.py and pages_ssd1306.py. After I press CTL+X , and Restart with sudo systemctl restart pydPiper. The Display is showing me again exact the same like bevore the modification. Of course I did reboot also a lot of time. I seems to me, that I use the wrong Page Files... because the File is modified but shows the old state.

The display is working. I can also chose between the pages files, when I Modify the "ExecStart..." ind pydpiper.service. And restart with:

sudo systemctl stop pydpiper sudo systemctl disable pydpiper sudo cp pydpiper.service /etc/systemd/system sudo systemctl enable pydpiper sudo systemctl start pydpiper

I use Raspberry 2B Volumio 2.834 Oled Display ssd1306 Hifiberry Amp2

I'm a beginner for Raspberry, so I hope i forget maybe a small thing like compiling or something.

I have also a second Question: is it possible to rotate the display view 180 degree?

It is likely that your docker run command does not expose the content of /home/volumio to the container. Can you send your pydpiper.service file? You'll need to rename the file to have a txt extention (e.g. pydpiper.service.txt) to attach it to this message.

Can you also let me know what version of pydPiper you are using? v0.3-alpha? Or the latest main branch code?

Hi,

first of all, thank's for the very fast help! I attached my pydpiper.service file. I use v0.3-alpha. I have used the installion instructions form "https://github.com/dhrone/pydPiper"

By the way, is it possible to rotate the view of the Display 180°?

pydpiper.service.txt

Now, I got it to work, with your hint.

I used the Example from pydpiper.volumio.service from Master Data and modified it to:

ExecStart=/usr/bin/docker run --network=host --privileged -v /var/log:/var/log:rw -v /home/volumio/pydPiper-0.3-alpha:/app:rw dhrone/pydpiper:v0.31-alpha python /app/pydPiper.py...

Maybe the wrong File is being installed. Or you could at a Description in the Manual, for Noobs like me.

If it would be possible to rotate the display view 180°, then I would be complete satisfied.

You are in luck. The driver you are using is from the luma.oled project which does support rotation. pydPiper does not currently expose this capability but it is a simple code change to enable it. You will need to edit pydPiper/displays/ssd1306_i2c.py line 47. Change it from...

self.device = ssd1306(serial) to self.device = ssd1306(serial, rotate=2)

Be careful not to change the indent of the line. It should line up with the line above it.

If've seen that it should be possible with the luma.oled, but I was not able to choose the right line. It's working! Thank you very much!
