epd_display's Issues

C to F

Looking in the config files; cannot find where to convert the Met No from Celsius to Fahrenheit? Can you point me in the right direction? Thanks.

tar file corupt

pi@raspberrypi:~ $ tar xvzf paperpi_latest.tgz
paperpi/./dist/paperpi

gzip: stdin: unexpected end of file
tar: Unexpected EOF in archive
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now

change the way config files are loaded

Currently system config and user config are loaded; when running as a user, skip the system config.

epd_display/paperpi/paperpi.py

Line 135 in c94726d

 config_files_list = [constants.config_base, constants.config_system, constants.config_user] 

add better handling when IT8951 driver cannot be reached at init and possibly during run time

When the driver board cannot be reached:

related to Issue #3

command line arg --plugin_info appears to print info multiple times

--plugin_info appears to print the module info multiple times. Print statement is likely called multiple times. Problem is likely here or here

This can likely be fixed by passing print(get_help.get_help(cmd_args.options.plugin_info), print_help=False)

Make it possible to display animations on plugin screens

This will likely require an entire rewrite of the plugin architecture and display loop.

method for adding plugin configuration to .ini file

When a new plugin is added there's no easy way to add the suggested configuration to the config file.

There should be a simple method for doing this from the command line.

Plugin Ideas

Pull quotes similar to Audry
Pull images from google image, imgr, etc. and display in rotation
Add stock quotes plugin -- build similar to weather plugin allowing multiple stocks to be tracked on individual screens
NYT Headlines
NPR Headlines

Command line option: --list_plugins has print statement in wrong location

--list_plugins lists the plugins as it builds the list. The print statement is likely in the wrong part of the loop.

add better error handling on new_epdlib branch when epd library cannot be loaded

crashes on unknown epd -- offer better feedback to user

Paperpi doesn't find Numpy though module is installed

Getting the below when trying to run Paperpi. Numpy was installed using apt install python3-numpy. I have also tried pip3 install numpy. Same outcome. Anyone have any ideas?

crash on unknown plugin layout

when an unknown layout is found, PaperPi crashes -- instead consider raising a WARNING and skip the loading of the module:

Plugin Idea - BitBot

A crypto / stock tracking script

https://github.com/donbing/bitbot

Add attributions to veeb

Reddit and crypto both inspired by veeb.ch Audry project; add attributions in docs

Documentation error

In a number of places across documentation for this project (Plugins.md, step_by_step_instructions.md) the location of the configuration file is (incorrectly) referred to as /etc/defaults/paperpi.ini instead of /etc/default/paperpi.ini. Presume this is a typo?

Add unit of measure (C/F) to met_no weather plugin

It appears that the plugin might be modified to switch between celsius to fahrenheit but moving that to the plugin config would be significantly easier for an end user. (I am the end user. :( )

spotify plugin causes crash when local librespot client is not responding

This appears to be due to a variable assignment issue in the spotify plugin that can be easily resoloved:

Update IT8951 support in readme.

Create_devel_venv.sh failed

See the output below. Issue was fixed by manually running sudo apt-get install libcairo2-dev libjpeg-dev libgif-dev and then running the shell script again. I believe this should be a quick fix in the "cd_apt_packages" file, but, I'm not sure. If it is just a simple add to the CORE var, I'm happy to make the change and submit the PR.

move plugins out of pyinstaller frozen blob

The pyinstaller frozen blob is getting rather large for a one-file distribution. Consider moving the modules out into a system path and then using sys.path.append('/mypath/scriptlib') to add the modules to the system path.

This would likely only require changing the path in the constants file

self-document all available layouts

add feature that self-documents all the defined plugin layouts; add these images to the README for each plugin.

screen does not clear properly when daemon is stopped

@jhaake2308
Screen does not clear when daemon is stopped through systemctl. Systemd may be killing the process before it has a chance to complete cleanup.

New Yorker returns bad image data only when in daemon mode:

paperpi[1810]: 14:19:26 paperpi:update_loop:532:CRITICAL - Plugin: New Yorker Comic returned invalid image data; screen update skipped

This appears to only be an issue when staring in daemon mode. This may be related to Issue #1

Support for epd3in7

I have a 3.7 HAT screen and would love to add support. Would you prefer a modified version of the standard Waveshare py file (modify the actual functions) or an inline interface file that can handle the function calls between the two?

In short, I would love to get this working with my 3.7 screen and am willing to do the work to make that happen. I'm just looking for a preferred direction (if you have one).

Unknown waveshare module when set to HD and no VCOM setting

With the following settings paperpi throws "unknown module HD" when no vcom is not set. This should indicate that there is a missing vcom setting rather than an unknown display type.

display_type = HD
vcom = 0

AttributeError: 'EPD' object has no attribute 'display'

Waveshare 3in7

I am able to run the waveshare demo

I have disabled all plugins so the only thing changed is the display_type

Add 64-bit OS support

Trying to run the program on the new 64-bit Raspbian OS causes the error bash: ./paperpi: No such file or directory as it's looking for the non-existent ld-linux-armhf.so.3 interpreter.
[Requesting program interpreter: /lib/ld-linux-armhf.so.3]

After some troubleshooting, I was able to get it running using the following commands:
sudo dpkg --add-architecture armhf

Which resulted in this error:
./paperpi: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory

That was resolved with this command:
sudo apt-get install zlib1g:armhf

Which resulted in this error:

This appears to allow the 32-bit compiled version to work as intended with the same results as my locally compiled 64-bit version. I'm not sure if these three commands can just be added to a shell script for running if the compiled version doesn't work or maybe just added to the README.md on here.

garbage collection for cached files

Plugins should be able to clean up their private cache on demand.

add a method to Plugin() class that does garbage collection on cache

write into display loop garbage collection every N refreshes or Y days or something similar.

Change distribution method from Frozen PyInstaller glob

Currently PaperPi is distributed as a single Frozen glob using PyInstaller. This is brittle, large and generally a pain to maintain. It is also not possible to add, test, or adjust plugins without rebuilding the entire project and redistributing it. This isn't ideal.

Finding a new distribution method would be much better.

Paperpi freezing

Hi; I have downloaded paperpi on a raspberry pi 3 using the current outlook rendition. I am operating a waveshare 4.2 screen. Download was fine and set up on Damon. I am running the word clock and phases of the moon. Problem is that the system starts, and works fine for about 12 hours. It then simply freezes; and does not function. I thought it might be a bad download; so I performed a new download with a new SD card. Same problem. I then changed to a different Raspberry Pi 3b that I had sitting around. Same problem. As it starts and functions for 12 hours; I doubt it has anything to do with the wiring. Any ideas? Looks great when operating; however, having to restart it every 12 hours is a non player. Please let me know if there is something else I can do. Thanks.

uninstall does not appear to work properly

$ ./install.sh --uninstall does not appear to work.

Update_loop appears to ignore max_refresh value in config file

See issue here from @jhaake2308

As it seems, the config parameter max_refresh (which is set to 30 in my case in paperpi.conf) is ignored. Every four changes there is a hard refresh. See this, the last refresh is done right before the video starts:

edit: video doesnt work, see gif at: https://imgur.com/a/6eoObdo
thank god its 2021, you can pause the gif, move forward, etc.

I am using a daemonized setup, defining max_refresh in /etc/default/paperpi.ini
# CONFIG_VERSION=1
[main]
# waveshare display type use HD for IT8951 displays
display_type = HD
# required vcom value for IT8951 screens
vcom = -2.13
# maximum refresh between total screen clear for HD displays
max_refresh = 30```

is this intentional or did I do this wrong?

Looking for specific advice for locating logs for daemon instance of paperpi, as well as any advice as to what's not doing the thing.

When starting as a daemon from systemd, no images are shown until first plugin timesout

When starting from systemd at boot, PaperPi may fail to show the splash screen and the first module. This is due to a NoneType object being passed to the epdWrite() function.

This has been exceptionally difficult to debug because it only happens at boot time from systemd. When started from the command line, this problem does not manifest.

Logging shows the image is generated, but fails to pass to the epdWrite() function.

Any help in solving this would be greatly appreciated.
