## Software

The firmware is written in Rust with ESP-IDF. [epd-waveshare](https://crates.io/crates/epd-waveshare) is used for E-Paper controlling and a custom fork of [untis-rs](https://crates.io/crates/untis) for fetching data from Untis.

## Components

The device consists of an esp32 controller, a 7" E-Paper-Display (and a driver board for it), a battery with charging controller with USB-C port and a 3d-printed casing.

## Goal

I wanted to have a hands-free timetable in my school locker. Just like the good old times when you didn't need your phone to check your timetable. This device uses e-paper to create one of them good ol' paper timetables, except its always up-to-date. I built this for my "Seminararbeit" (a wannabe research paper you have to write in german highschool)
