Describe the bug No longer able to launch InkyCalendar. Process crashes fetching events from calendars

To Reproduce Steps to reproduce the behavior: python3.5 /home/pi/Inky-Calendar/Calendar/E-Paper.py

Expected behavior Inky-Calendar should launch and load events.

Additional context For some reason Inky-Calendar reset to default "settings.py". I went through the Web-UI and re-created the same settings I've always had. But it's now throwing errors.

BETA testing

Welcome to the BETA-testing of release v1.7. Thank you for willing to test the new software. As the Installer of the new release is still work in progress, an alternate way to install the software had to be found. For now, the Inky-Calendar software is offered as a pre-configures OS image, which you can simply flash on a blank MicroSD card.

Below is the link on where you can download the image file. Below are the steps on how to set up the OS and the Inky-Calendar software:

1. Download and unzip the OS file (with 7z) from here: BETA-RELEASE

2. Format an empty MicroSD card (with SD Card Formatter) with at least 8GB space and flash the OS on the card (with Balena Etcher)

3. Open Editor (on Windows) and paste the following to setup WiFi:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=US

network={
 ssid="WiFi-Name"
 psk="WiFi-Password"
}

Edit the 2-letter country-code, ssid and psk with your own. Make sure you don't add spaces after the = signs. Save the file as wpa_supplicant.conf in the boot directory. If you have access to an Ethernet connection, you don't need to setup WiFi.

4. Add the SD card in the RPi and connect via VNC Viewer (preferred) or SSH. The hostname is inkycal.local ,the username is pi and the password is raspberry (default values). You can also use the IP address of the Rpi instead of the hostname.

5. Expand the filesystem in the Terminal with sudo raspi-config --expand-rootfs and set the correct timezone with sudo dpkg-reconfigure tzdata

6. VNC Viewer: Go to Inky-Calendar, open the settings folder and paste your details in settings.py SSH: cd /home/pi/Inky-Calendar/settings && nano settings.py

7. VNC Viewer: Open the modules folder inside the Inky-Calendar folder, open inkycal.py and run with the main programm file by pressing the [F5] key. SSH: cd /home/pi/Inky-Calendar/modules && python3 inkycal.py

Once the main programm has started, you'll see the E-Paper display being refreshed.

Updating

For those who have installed this software already and wish to perform an update, below are the instructions:

• Rename the current Inky-Calendar folder to anything you like, e.g. Inky-Calendar-old

• open the Terminal and run the following command: git clone -b dev https://github.com/aceisace/Inky-Calendar This will take some time as it will download 120 megabytes of data.

• Copy your previous settings file (in this case inside 'Inky-Calendar-old/settings/settings.py') and paste it in the settings folder of the 'new' Inky-Calendar folder. You can use this command as well: cp Inky-Calendar-old/settings/settings.py /Inky-Calendar/settings/. Replace 'Inky-Calendar-old' with the name of the old Inky-Calendar folder.

• Create symlinks (symbolic links) for the settings file and configuration file: ln -s /home/pi/Inky-Calendar/settings/settings.py /home/pi/Inky-Calendar/modules/ ln -s /home/pi/Inky-Calendar/settings/configuration.py /home/pi/Inky-Calendar/modules/

• Run the new software VNC Viewer: Open the modules folder inside the Inky-Calendar folder, open inkycal.py and run with the main programm file by pressing the [F5] key. SSH: cd /home/pi/Inky-Calendar/modules && python3 inkycal.py

Hi, I've followed all the installation instructions but cannot get an image on my Waveshare 7.5in three color display.

• Version info; Version: 1.5 Installer version: 1.5 (Early February 2019) configuration file: /home/pi/E-Paper-Calendar/Calendar/settings.py If the time was set correctly, you installed this software on: Tue Apr 16 16:11:34 PDT 2019

• Additional Notes: _There may be other issues with the display and/or drivers. I'm unable to get Waveshare demo code to work. Terminal always returns "e-Paper busy"

I have checked and re-checked that I've installed all drivers/python/libraries, etc. I'm very new to this and bought it to learn, so please forgive something I might be missing. Appreciate your work on this._

Panel order should dynamic: panels (modules) should be told their dimensions instead of determining themselves based on figuring out their position by reading from settings.py.

Any logic that is based on the position (where a panel should know if is it at the top, middle or bottom) is yet to be determined, if to exist at all.

This would also allow changing the number of panels (with a minimum of one of course)

Bug reports

Here you have an option to chat about the Inky-Calendar software (v1.7.1) with the author (me) as well as other users from the community.

This issue is mainly intented to help identify bugs/errors/problems in the software. Once something has been reported, I'll try to take care of it as soon as possible.

P.S: Please remember to be nice :)

Describe the bug I have performed a clean install on a Pi Zero WH and have a 5.83" epaper display attached. I get the following error(s) when I manually run inky_run.py:

pi@rpiz-inky:~ $ python3 inky_run.py

mgfcf's E-Paper Calendar fork

Amongst the forkers of this software,, mgfcf (Max G.) has been working hard on the E-Paper software refactoring. Apart from some more design options, it's also modular so it's easier to modify.

I am very thankful to Max G. for taking the time on refactoring the E-Paper software. But since there is hardly any 'perfect' software, bugs and errors can still occur. The aim of this issue is to provide a way to interface with mgfcf (for bugs, errros, etc.).

As usual, nothing and nobody is perfect, but we can strive to get closer towards that. Please post your comments in a friendly way and remember to be nice. Thanks for your understanding.

Is anyone working on a module to link to Todoist or equivalent? I have been looking at the various e-ink calendar systems and I think that is the critical capability. I've got my hardware ready, and this is an awesome project! Thanks!

Describe the bug For several projects in the project_filter, the inkycal_todoist module only imports the first project.

To Reproduce Try to import more than one project from todoist.

Expected behavior All tasks from all projects in the project_filter list should be imported and printed. Here, a small bug has been found: In the for-loop which is used to generate the image, the else case with break ("more todos than available lines") is lined up with "if todos:". It should line up with "if cursor < len(line_positions):". This change in the code has solved the issue for me.

Screenshots If applicable, add screenshots to help explain your problem.

To Reproduce There are several packages for the todoist_api. The installed one is wrong, the correct one should be: todoist_api_python. Therefore, please change the prints following the importError exception to: print('pip3 install todoist_api_python')

Release version = 2.0.0 Expected behavior = e-ink display to update with modules Actual behavior = upon start up OS works fine, no update on display Steps to reproduce the behavior = before installation input all things needed for installation and inky wHAT is already connected

I am trying out this code today and it is not working out of the box after installation with the Inky wHAT with a 4.2 in e-ink display.

I have not tried out the pHAT since it is a smaller 2.13 in screen.

Describe the bug If two ical calendar sources contain the same event (e.g. one as invitee, one as organizer), the ical agenda shows them duplicate, even if the UID is the same.

To Reproduce

1. Create two ICS files with the same event (same UID)
2. Setup agenda module with both ICS files.
3. Start inkycal

Expected behavior Only one instance of this event is shown

As ace and I discussed a while back (mid-2020?) the unicode weather icons report an incorrect size in the y direction. Some of the icon's sizes are off by enough that the human eye can see that they are no longer centered in the y direction.

During another project of mine, I went through each icon and added a manual scaling factor that, when used along with the font size, can help us properly center the icons. I had difficulty integrating that scaling factor into the weather module because it's a very complicated program and ace wrote it.

But I think I figured it out: By editing the y alignment line in the draw_icon function to factor in this size correction, all the icons are now correctly centered. That appears to be the case with my 12" screen, although I haven't yet tested it on a 7.5" screen. I would appreciate others testing this out for me and seeing if there's any ill-effects on smaller screens.
