Project guide

Overview

This project's code uses the CircuitPython OAuth Library for authentication with Google services. Due to Google's update to the OAuth "authentication flow", the library became incompatible. As a result, this project does not currently work (but may in the future)!

Keep an eye on your schedule with this MagTag Google Calendar Event Viewer. This CircuitPython project uses the Google Calendar API to retrieve a list of the latest events from your Google Calendar and displays them on the MagTag's e-Ink screen.

Between fetching new events on your calendar, the MagTag goes into a deep sleep mode to conserve battery life.
