Sapnho - you have no idea, how many digital picture frames pi projects I've tried, and this for me is on top! Amazing write ups. Thank you for taking the time to document your work. Thanks! But the glory belongs to Paddy because of his work on Pi3D. At home, we discover great new "images" every day...

I am still not sure what the issue for this is, but a user had found this solution and has been a happy camper ever since: Finally got it to work by editing the "rc.local" -https://www.dexterindustries.com/howto/run-a-program-on-your-raspberry-pi-at-startup/ I entered sudo nano /etc/rc.local right b...

Paddy's latest Pi3D update is another great improvement. I have explained the various settings and functionalities here: https://www.thedigitalpictureframe.com/ ... -nov-2019/

Thanks so much, Paddy!

I can answer that myself. I need to sudo pip3 install pi3d --upgrade Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple Collecting pi3d Downloading https://files.pythonhosted.org/packages/ed/1e/a9ce342e89305c444494dc1be5054bc9646dc10128177f418a5f18c649ac/pi3d-2.33-py2.py3-n...

@paddyg, when I enter

Code: Select all

[email protected]:~ $ sudo pip3 install pi3d

I still get 2.32

Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
Requirement already satisfied: pi3d in /usr/local/lib/python3.7/dist-packages (2.32)

Anything I am doing wrong?

Ah, just found out that it actually works in HDMI 0 (I believe that is the left HDMI slot of the two)

Does anybody know how to activate it also for HDMI 1?

sapnho

I only just got around to checking on the updated vcgencmd in Buster which again allows for turning the hdmi output on/off. So I updated everything with sudo apt update && sudo apt full-upgrade and rebooted. However when I enter sudo vcgencmd display_power 0 the display doesn't turn off. Does it wor...

Hi @paddyg, I had one guy having a problem installing the latest Pi3D on a Raspberry Pi Zero and we never had this error message before (latest Buster). sudo pip3 install pi3d wget https://github.com/pi3d/pi3d_demos/archive/master.zip && unzip master.zip && rm master.zip && mv pi3d_demos-master pi3d...

sapnho

Excellent news for all digital picture frame fans!

sapnho

Thanks @SohKahToa, glad you like Pi3D and the blog. This question should ideally be answered by @paggyg who is grail keeper of Pi3D. If I understood you correctly, you want your images to be maximised but not cropped and the remaining screen bits filled with blurred parts of the image. That is actua...

sapnho

Sadly, the images aren't rotated when shot in portrait mode. The exif info is there, as gpicview is showing the images rotated correctly. Any idea how to fix this? As far as I understand, Pi3D does not look at the Exif data for the file orientation. But it still works fine here, so there may be ano...

If you use tvservice to turn things off, and are not using the VC4 FKMS driver, you can use "fbset -depth 16; fbset -depth 32" to get the display back again after turning the display driver back on with tvservice.

Is there a way to get the display back when using the FKMS driver?

Thanks for the clarification, Jamesh. It would be most useful to have this feature back. Is this a Broadcom or Buster issue?

sapnho

Eine andere Möglichkeit wäre mit Dataplicity: https://www.thedigitalpictureframe.com/ ... derrahmen/

sapnho

I used this rather simple solution for a Raspberry Pi picture frame: https://www.thedigitalpictureframe.com/ ... taplicity/

sapnho

Thanks to @paddyg, Pi3D now works on the Pi 4. I have updated my article to reflect the changes: https://www.thedigitalpictureframe.com/ ... sing-pi3d/

sapnho

Hi @DDIT, please contact me directly so we can get to the bottom of this. Details are on my website.

sapnho

Ok, I am fishing for clues here...

In one script I had to add

Code: Select all

sleep 30

to have the Pi wait for another process to be ready first. Can you try inserting this before calling your startup script in crontab -e?

So like

Code: Select all

@reboot sleep 60 && /home/pi/start_slideshow.sh >> /home/pi/cron.log 2>&1

sapnho

Hi @DDIT, does it work in the Terminal when you enter

Code: Select all

 cd pi3d_demos 
 python3 PictureFrame.py

?

sapnho

Beim Autostart gibt es viele Möglichkeiten. Dieser Artikel fasst es gut zusammen: https://www.dexterindustries.com/howto/run-a-program-on-your-raspberry-pi-at-startup/ So habe ich es für meinen Bilderrahmen gemacht: https://www.thedigitalpictureframe.com/de/so-erstellst-du-professionelle-ueberblendu...

Code: Select all

vcgencmd display_power 0

doesn't work on Buster + Pi 4. It works with Buster + Pi 3.

sapnho

Yes, that works and

Code: Select all

 /opt/vc/bin/tvservice -p; sudo /bin/chvt 6; sudo /bin/chvt 7

to turn it back on.

But I used vcgencmd in many areas and it would be nice to have it back.

sapnho

Ah yes, you must have one older Alexa Gen (2) in your network for devices to be discovered. Once that has happened, it works fine with all Echos.

sapnho

Yep, same issue here. Buster works fine on the Pi 3 but on the Pi4 the command doesn't work.
