RPi Information Screen for Official Raspberry Pi Display

[elParaguayo]

your English is great!

In answer to your questions, yes you could modify the code to rotate screens. I can explain how later tonight.

Webcam is harder. Firstly, I don't have one. Secondly, I don't know if kivy has a video player module. However, because of the first issue, it's not something I'd look to implement myself.

[elParaguayo]

Kivy does have a video player (https://kivy.org/docs/api-kivy.uix.videoplayer.html) so you may be able to get the webcam to work.

Thanks Dougie.

Could be hard to debug that one as the traceback just seems to reference kivy modules rather than my code. However, I do not doubt that the error is caused by something I wrote!

I'll add it to the issue list on github and take a look if/when I can.

Same error here. There are a few references on the Internet, but I did not find a solution to it.
It seems to work fine in a window on a Lubuntu VM.

[Drooneyef]

Thank you for helping me.

Can you also help me with the web server?
When i enter the right address in my browser i see the message connection refused.
Do i have to install something else on my raspberry to get it work?

[elParaguayo]

You need to have 'bottle' installed.

Hello,

First of all let me just say I'm very excited about this project. I've been looking into a Raspberry Pi alarm clock solution and this is by far the best looking option available. Plus its packed with so many features!

I have a couple questions about this project:
Has anyone tested this project using the latest Raspberry Pi 3?
Has anyone tried to get this working on Ubuntu-Mate?

I really like the look and feel of Ubuntu so was hoping to have that OS running in the background.

[elParaguayo]

I've not tested on pi3 but I don't see any reason that it wouldn't work (although it does seem that the ISS Tracker may be broken...)

As for Ubuntu Mate, all I can say is that the script works on my laptop (running Ubuntu 15.10). However, it is designed to run fullscreen on the official monitor so, if you want to change resolution or run windowed, you may need to tweak the code slightly.

Thanks! I'm planning to get the official monitor but until then how would I "tweak the code" to run it in windowed mode?

[elParaguayo]

if you're running the code in a desktop environment with a resolution greater than 800x480 then it should run windowed automatically.

[bigatl22]

Ok, I'm planning to test it on my RPI3 running the newest Ubuntu Mate v16.04 tonight.

[elParaguayo]

I've been playing with your project a few weeks now and i really like it.
I have a few questions.
Is it possible that the screens change automatically instead of clicking on the touchscreen?
Are you planning to make a screen for viewing an ip cam that's connected in your local network?

English isn't my native language so i hope you understand my questions.

Sorry Drooneyef, meant to reply to this earlier.

In order to change screens automatically, just add a clock object in the core/infoscreen.py file.

Add the necessary import:

Code: Select all

from kivy.clock import Clock

At the end of the __init__ method (but not nested in the "if" block), add the timer:

Code: Select all

Clock.schedule_interval(self.next_screen, 15.0)

(this moves onto the next screen every 15 seconds).

It's working great now

Anyone else got the problem that the program is crashing?
When i enable photoalbum it's working for a while and then the program stops with an error.
I turned photoalbum off now and then it's working for hours with no problems.

It ends with:

Exception: Shader didn't link, check info log

[elParaguayo]

I won't lie: I have no idea what that means. It's a Kivy error message and, having looked at the source, I can't work out what causes it to be triggered.

I am very happy to admit that the issue is likely to be with my code!!

Does the issue arise when the photoalbum has been viewed a certain number of times? How many photos are in the directories you're using?

I was able to get it working on the Pi3 running Ubuntu Mate. However, there is one issue...the GIFs are continuously flashing on the weather screen. How do I fix this?

Ok, thanks. So for someone who is unfamiliar with Kivy development and a beginner with python, how difficult would it be to add alarm button(s) to the clock screen or just set an alarm in the conf.json?

[elParaguayo]

I'd suggest you start with the kivy tutorial so you understand the basics before you try adjusting the screen.

I am also having a problem with the photoalbum screen crashing. It will cycle through a dozen or so photos and then the whole program just closes. I'm not seeing any error messages, just "Killed" in the terminal. I've tried different folders and adjusting the display duration but its always the same result. All my images are high resolution .JPG

[elParaguayo]

Ok. Sounds like that one is broken.

I'll add it to my issue list...

[veryaner]

Hi, excellent work.
I was playing around with some screens and I really like it.
I'm trying to make a "smart" dock for my night table and your infoscreen is great.
Do you plan to add an alarm?

I'm getting this error whey I try to use the web configuration:
Template 'all_screens.tpl' not found.

the file exists in the web directory by the way.

Thanks!

Sorry for my english (Paraguayo, is english your native language?? )
