Crossword program for the TI-84 Plus CE graphing calculator.

CrossBun

CrossBun is a crossword puzzle program for the TI-84 Plus CE graphing calculator. It's heavily inspired by Crosshare.

Installation

To install, transfer CROSSBUN.8xp and clibs.8xg from this repo to the calculator using TI-Connect CE or TiLP. On newer calculators (OS 5.5 and above), you'll need to use arTIfiCE and optionally a shell like Cesium to run the program.

You'll also need to transfer at least one .8xv file containing crossword puzzles in order to use the program. These can be created from .puz files using the convert.py script.

Arrow keys	Arrow keys	Move cursor around
2nd	2nd	Toggle cursor direction
A-Z (no alpha)	A-Z (no alpha)	Enter a letter

Converter

This repository includes a script to convert multiple .puz files into a single crossword puzzle pack for the calculator to read. To use it, you'll need to install the convbin utility (which is included with the CE C toolchain). You'll also need to install its dependencies, e.g. pip install puzpy bitstring tivars. Then, you can run it like so: python convert.py --title "My pack title" --description "Pack description input1.puz input2.put input3.puz MYPACK.8xv.
