The goal of this project is to design a functional operating system for a
graphing calculator based on the STM32L476RG processor. This OS has been
designed from scratch to optimize for speed and code size, targeting the
features necessary for a graphing calculator application.

## design overview
The core of the operating system is written entirely in C and assembly. This
project is paired with the [interpreter project](https://code.bitgloo.com/clyne/interpreter)
(licensed under the GPL),
which parses script from C strings. The operating system exposes calls to the
script parser, and then loads the text file at ```initrd/init```.
