Epsilon is a high-performance operating system for the NumWorks graphing calculator, written in C++, with eleven apps covering the high school mathematics curriculum. It can also be compiled as a standalone desktop application or run in a browser-based online simulator.
Use cases
- run a graphing calculator OS on a NumWorks calculator
- try a graphing calculator in the browser via the online simulator
- build custom calculator firmware
- develop external apps for the NumWorks calculator
- study embedded OS architecture from keyboard driver to math engine
- use a calculator for high school math coursework
When to choose
- you own a NumWorks calculator and want to update or customize its firmware
- you want to develop external apps or custom firmware for the calculator
- you need a free, open graphing calculator experience in a browser or on desktop
- you want to learn how an embedded math-focused OS is structured
When to avoid
- you need a calculator OS for TI or Casio hardware
- you want general-purpose embedded Linux development
- you need a license permitting unrestricted redistribution (the repo has no open license, all rights reserved)
