# Raspberry-Pi-Google-Calendar-with-E-Paper-display
|
|
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.
|
|
|
|
Altough mainly intended for the Raspberry Pi Zero W, mainly since it only requires 1W per hour, it works on the Rapsberry Pi 2/3 as well. To get started, follow the instructions below.
|
|
|
|
## News:
|
|
* **Version 1.2 released (early October 2018) with lots of improvements, especially for the 2-Colour version!**
|
|
|
|
**If you were using any previous versions, please update as this version contains a critical update. See below section regarding updating**
|
|
|
|
* **Added Support for the 2-Colour E-Paper Display as well!** (End of September)
|
|
* **Added Support for Raspbian Stretch lite.** (End of September)

**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
|
|
* MicroSD card (min. 4GB)
|
|
* MicroUSB cable (for power)
|
|
* Something to be used as a case (e.g. a picture frame or a 3D-printed case)

# Setup
|
|
|
|
## Getting the Raspberry Pi Zero W ready
|
|
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.
|
|
2. Create a simple text document named **ssh** in the boot directory to enable ssh.
|
|
3. Expand the filesystem in the Terminal with **`sudo raspi-config --expand-rootfs`**
|
|
4. Enable SPI by entering **`sudo sed -i s/#dtparam=spi=on/dtparam=spi=on/ /boot/config.txt`** in the Terminal
|
|
5. Set the correct timezone with **`sudo dpkg-reconfigure tzdata`**, selecting the correct continent and then the capital of your country.
|
|
6. Reboot to apply changes
|
|
7. Optional: If you want to disable the on-board leds of the Raspberry, follow these instructions:
|
|
**[Disable on-board-led](https://www.jeffgeerling.com/blogs/jeff-geerling/controlling-pwr-act-leds-raspberry-pi)**
|
|
|
|
## Installing required packages for python 3.5
|
|
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.
|
|
|
|
**`bash -c "$(curl -sL https://raw.githubusercontent.com/aceisace/E-Paper-Calendar-with-iCal-sync-and-live-weather/master/Installer-without-debug)"`**
|
|
|
|
Should you encounter any problems during the install, try using the Installer with output, like this:
|
|
|
|
`bash -c "$(curl -sL https://raw.githubusercontent.com/aceisace/E-Paper-Calendar-with-iCal-sync-and-live-weather/master/Installer-with-debug)"`
|
|
|
|
If the Installer should fail for any reason, kindly open an issue and paste the error. Thanks.
|
|
|
|
This is how the installer will run:

|
|
|
|
## Adding details to the programm
|
|
Once the packages are installed, navigate to the home directory, open 'E-Paper-Master' and open the file 'stable.py' inside the Calendar folder.
|
|
|
|
3 Main Details are needed to get running:
|
|
1. A valid ical URL. Use the export funtion in google calendar to create a ical url link and paste it in the url section
|
|
2. A valid openweathermap API-Key is required. This key can be optained for free with an account on openweathermap
|
|
3. Your city's name and your country code (so the correct weather can be displayed) (e.g. `New York, US`)
|
|
|
|
## Demo
|
|
Once you have setup everything, the E-Paper Calendar will refresh the screen in the following way:

|
|
|
|
## Updating
|
|
If you were using a previous version and want to update, do the following:
|
|
|
|
* Save your personal details from the main script, located in `/home/pi/E-Paper-Master/Calendar/stable.py` in a different location.
|
|
For example you can create a text file which contains your openweathermap-api-key and iCal-url in `/home/pi/personal.txt`
|
|
|
|
* Remove the E-Paper-Master folder from the home directory with `sudo rm -r /home/pi/E-Paper-Master/`
|
|
|
|
* Re-run the (updated) installer and insert your details again in stable.py. Reboot to apply changes.
|
|
|
|
## Don't forget to check out the Wiki. It contains all the information to customising, understanding and setting up the script.
