+# Eink family calendar
+
+## What is it?
+I needed to have an updatable calendar to keep track of my children's school agenda,
+as well as some post-school activities. So instead of using a whiteboard, I thought
+it would be a nice holiday project to do it with a Raspberry Pi 2 and an e-ink
+screen.
+
+## What do you need
+- A Raspberry Pi (any model would do, I did it with a Pi 2), with the Raspberry Pi OS.
+- Eink display: [640x384, 7.5inch E-Ink display HAT for Raspberry Pi, yellow/black/white three-color](https://www.waveshare.com/product/displays/e-paper/epaper-1/7.5inch-e-paper-hat-c.htm).
+- A [1x4 matrix keypad](https://www.adafruit.com/product/1332) to allow you to switch
+  between the different calendars. There are multiple clones in different shops.
+- A photo frame to house the setup. I bought one at a local shop, just make sure it has
+  enough depth to host all the hardware.
+- One or more Caldav calendars to display.
+
+## Configuring
+Once the basic setup and connections are done (TODO: add diagram for GPIO connections),
+you will need to set up the `config.ini` file. This is the syntax:
+
+```ini
+[DEFAULT]
+video = pygame
+keyboard = pygame
+
+[weather]
+owm_api_key = <insert API key here>
+owm_location = <insert location id here>
+
+[calendar]
+urls = http://example.com/caldavcal1, http://example.com/caldavcal2, http://example.com/caldavcal3
+names = user1, user2, user3
+username = user
+password = password
+```
+
+### Driver configuration
+We have two different drivers to be used for both video output and keyboard input.
+This allows us to hack and tests locally without using the e-ink screen all the time.
+
+- For video, we can use `pygame` for the [Pygame](https://github.com/pygame/pygame)
+  driver, or `eink` to use the e-ink screen.
+- For keyboard input, we can use `pygame` to get input from your computer's keyboard,
+  or `gpio` to use the 1x4 keypad connected to the GPIO pins 29 ,31, 33, 35 and 37.
+
+### Open Weather Map API configuration
+You need to subscribe to the "Current Weather Data" API [link](https://openweathermap.org/api).
+Note that you need to sign in as a user (it's free). Once you get the API key and the
+location id for your town, add them to the `owm_api_key` and `owm_location` keys in
+the configuration file.
+
+### Calendar configuration
+You can use any CalDav link; in my case, I set up 3 calendars in a [Synology](https://www.synology.com)
+DiskStation. The code should adapt to any number of calendars, but keep in mind the
+resolution and font size ;).
+
+The `urls` parameter is a comma-separated list of CalDav urls. Since each of those
+calendars will correspond to an actual person, `names` will contain the list of
+names for each url. Make sure you spefify the same number of urls and names.
+
+The `username` and `password` fields are self-explaining: include the user and
+password to access the calendars.
+
+If you want to use a different type of calendar, such as Google Calendar, you
+will need to create a new driver. Patches are welcome :).
+
+## Running
+The scripts directory contains a simple launcher script using a virtual environment,
+and a systemd unit file you can use to ensure the program runs on startup.
+
+When the application is stopped, it should clear the e-ink display, which is a good
+idea to avoid displa burnout. In some cases, it may not happen (for example if
+you get a power disruption). You can use the `reset_eink.py` script in those
+cases to clear the screen.
+
+## Usage
+When started, the calendar will show today's calendar for everyone, from 8:00 to
+21:00 (times are not configurable at the moment). You can switch to a weekly, Monday-to-Friday
+calendar for each person by pressing the 2, 3 or 4 buttons in the keypad, and
+switch back to the daily calendar by pressing 1. Yes, that means that having
+more than 3 calendars could require code changes ;).
+
+After 9 PM, the calendar will enter in screensaver mode, and display the image
+in the `img/night_image.jpg` file. The image will be converted to a 1-bit format,
+so it's better if you use a 1-bit image already.
+
+If there is a JPG or PNG file named after today's date, in DD-MM-YYYY format
+(for example, 01-01-2022.png for January 1st, 2022), the screensaver will use that
+image instead of the default one. Be creative!
