This is a software written in python3 that allows you to transform an E-Paper display (like the kindle) into an information display. It fetches live data from Openweathermap (a weather info provider) and your Online Calendar (Google/Yahoo Calendar) and displays them on a large, beautiful and ultra-low power E-Paper display. It's ideal for staying organised and keeping track of important details without having to check them up online.
This software fully supports the 3-Colour **and** 2-Colour version of the 7.5" E-Paper display from waveshare/gooddisplay and works with Raspberry Pi 2, 3 and 0 (Zero, Zero W, Zero WH).
**To get started, follow the instructions below.**
* 7.5" 3-Colour E-Paper Display (Black, White, Red/Yellow) with driver hat from [waveshare](https://www.waveshare.com/product/7.5inch-e-paper-hat-b.htm)
**or**
* 7.5" 2-Colour E-Paper Display (Black, White) with driver hat from [waveshare](https://www.waveshare.com/product/7.5inch-e-paper-hat.htm)
* Raspberry Pi Zero WH (with headers) (no soldering iron required)
* Or: Raspberry Pi Zero W. In this case, you'll need to solder 2x20 pin GPIO headers yourself
1. After [flashing Raspbian Stretch (Lite or Desktop)](https://www.raspberrypi.org/downloads/raspbian/), set up Wifi on the Raspberry Pi Zero W by copying the file **wpa_supplicant.conf** (from above) to the /boot directory and adding your Wifi details in that file.
Execute the following command in the Terminal to install all required packages. This will work on both, Raspbian Stretch with Desktop and Raspbian Stretch lite.
Once the packages are installed, navigate to the home directory, open 'E-Paper-Master' and open the file 'settings.py' inside the Calendar folder. Adjust the values as needed. You can use the table below as a reference. You can edit the settings.py file by typing:
`nano /home/pi/E-Paper-Master/Calendar/settings.py` in the Terminal.
|events_max_range| How far in the future should events from your iCalendar be fetched. The value is given in days. By default, events in the next 60 days will be fetched from the Calendar. Can be any integer from "1" to "365"|
| api_key | Your __personal__ openweathermap API-key which you can generate and find in your Account info |
| location | Location refers to the closest weather station from your place. It isn't necessarily the place you live in. To find this location, type your city name in the search box on [openweathermap](https://openweathermap.org/). The output should be in the following format: City Name, Country ISO-Code. Not sure what your ISO code is? Check here: [(find iso-code)](https://countrycode.org/) |
| display_colours | This should normally be set by the installer when you choose the type of your display. Options include `"bw"` if you're using the black and white E-Paper or `"bwr"` when you're using the black-white-red or black-white-yellow E-Paper|
| language | Choosing the language allows changing the language of the month and week-icons. Possible options are `"en"` for english and `"de"` for german|
|units| Selecting units allows switching units from km/h (kilometer per hour) and °C (degree Celcius) to mph (miles per hour) and °F (degree Fahrenheit). Possible options are `"metric"` or `"imperial"`|
|hours | Which time format do you prefer? This will change the sunrise and sunset times from 24-hours format to 12-hours format. Possible options are `"24"` for 24-hours and `"12"` for 12-hours.|
Currently, only Google Calendar is fully supported and has proven to run more stable than others. While it is possible that a non-Google iCalendar may work, it is often not the case. If you're not using Google-Calendar and the script is throwing errors related to your iCalendar, please export your iCalendar (as an .ics file), create a new Calendar at Google Calendar and import your previous Calendar's .ics file. After importing, navigate to the section 'Integrate Calendar', copy the 'Secret address in iCal format' and paste it in the ical_urls section in the settings.py file (see instructions above).
Try avoiding too long event names in your Calendar. If an event is too long, it'll be 'chunked off', letter by letter, from the end until it fits.
Event dates and names are displayed in chronological order below the Calendar. The small squares on the monthly Calendar indicate events on those days. For example, if you see a small square on the 14th of the current month, it means you have/had an event in your iCalendar on that day.
If you encounter errors related to your iCalendar, please feel free to report the error either by opening an issue or by sending a mail.
If you want to update to the latest version, run the Installer from above again and select the 'update' option.
Before updating, the Installer checks if the settings file (/home/pi/E-Paper-Master/Calendar/settings.py) exists. This is done to test if a previous version was installed correctly. If the settings file exists, it is copied to the home directory and renamed as 'settings.py.old'. The old software folder 'E-Paper-Master' is renamed to 'E-Paper-Master-old'. Lastly, the latest version of the software is copied to the Raspberry as 'E-Paper-Master'.
After updating, copy the contents from your old settings file to the new one. There are usally more options in the new settings.py file so a 'template' is prepared with each update. This template can be found in /home/pi/E-Paper-Master/Calendar/settings.py.sample.
