waveshare-epaper-display | glance dashboard for Raspberry Pi

The script will by default get its info from your primary Google Calendar. If you need to pick a specific calendar you will need its ID. To get its ID, open up Google Calendar and go to the settings for your preferred calendar. Under the 'Integrate Calendar' section you will see a Calendar ID which looks like xyz12345@group.calendar.google.com. Set that value in env.sh. The Oauth process needs to complete once manually in order to allow the Python code to then continuously query Google Calendar for information. Go to the Python Quickstart page and enable Google Calendar API. When presented, download or copy the credentials.json file and add it to this directory. Next, SSH to the Raspberry Pi and run. The script will prompt you to visit a URL in your browser and then wait. Copy the URL, open it in a browser and you will go through the login process. When the OAuth workflow tries to redirect back (and fails), copy the URL it was trying to go to (eg: http://localhost:8080/...) and in another SSH session with the Raspberry Pi,. On the first screen you should see the auth flow complete, and a new token.pickle file appears. The Python script should now be able to run in the future without prompting required. I also have a post here with screenshots walking through the process.
