README.md

PythonExtra - A community MicroPython for CASIO calculators

Original MicroPython README: README-MicroPython.md.

This is a MicroPython port for fx-CG 50, fx-9860G III and related CASIO calculators.

TODO list

Bugs to fix:

  • Don't refresh screen at every low-level console print
  • Fix not world switching during filesystem accesses (very unstable)

Python features:

  • Compare features with existing implementations and other brands
  • Get filesystem access (open etc) with the POSIX interface
  • Get a decent amount of RAM not just the fixed 32 kiB that's hardcoded so far

UI:

  • Use JustUI to get a file browser (already available)
  • Add an option for fixed-width font which also sets $COLUMNS properly so that MicroPython paginates (requires better getenv/setenv support in fxlib)
  • Use unicode-fonts to provide Unicode support
    • Extend it with a fixed-width uf8x9 which maybe changes some glyphs (like i and l; the usual fixed-width unambiguous styles)
    • Try and provide a font smaller than 5x7 for more compact shell on mono

Future wishes:

  • Build for fx-9860G II (requires manual filesystem support)
  • Lephe's secret ideas (complete previous list to unlock)
