Deimos is an operating system written in Zink for Raspberry Pi Picos and Pico Ws running MicroPython.
Deimos implements many features that aren't normally present on cheap non-programmable calculators like the Casio fx-991CW, such as:
- Robust API for user-made applications and libraries;
- Stable foundation for other calculator projects (like other OSes);
- Integrated file editor to make Python projects on the go.
Currently, the API supports the CWII series and the CWI series through itzmtt's port. CWII+ calculators (like the fx-9910CW) are already supported since they ship with the same hardware as their older CWII counterparts.
This GitHub repo was originally meant to keep track of releases and code changes. For now, you can find more information on the Discord server.
