This is the Python code that runs the UCLA EMS E-Ink Display to show logbook information, announcements, and maintenance duties. To maintain the functionality of the paper maintenance calendar, the screen also recognizes holidays and our EMTs' birthdays. This project gets information from various Google Sheets (used by administrators as a "back-end"), parses the data, and prints to an e-ink display.

- Waveshare 7.5" (800x480) black and white e-ink display
- Waveshare e-Paper HAT
- 3D printed enclosure (STL files in repository)
- 12x M2.5 Heat-set inserts from Virtjoule (buy on Amazon as a bundle with tip for soldering iron)
- 12x M2.5 5mm machine screws (buy on Amazon here) -- I think these could have been a bit shorter (<5mm length)
Information about getting started with the Waveshare e-ink display may be found here.
Additional software must be installed for the program to work properly! You should also follow the instructions to install the Waveshare EPD package (available here).
