LOGiCE

LOGiCE is a powerful boolean algebra simplifier and analysis tool for the TI-84 Plus CE calculator family. It uses the Quine-McCluskey algorithm to minimize logic expressions with up to 10 variables.

Features

• Minimization: Simplifies expressions with up to 10 variables (A-J).
• Visualizations:
  • Karnaugh Map
  • Truth Table
• Safety: Handles large expressions by automatically exporting to system variable Y1 if the output is too long for the screen.
• Input: Supports standard notation (+ for OR, * for AND, ! for NOT).

Installation

To run LOGiCE, you need a TI-84 Plus CE (or CE-T / Python edition).

1. Download: Grab the latest LOGiCE.8xp from Releases.
2. C Libraries (Important!): You MUST have the CE C Libraries installed (clibs.8xg). If you don't have them, download them here and send them to your calculator.
3. Transfer: Send LOGiCE.8xp (and clibs.8xg if needed) to your calculator using TI Connect CE or TiLP.
4. Jailbreak (OS 5.5+): If your calculator runs OS 5.5.1 or newer, you cannot run ASM programs directly. You need to use arTIfiCE and a shell like Cesium to launch the program.

Controls

Key	Action
A - J	[Math], [Apps], [Prgm], ... (A-J shortcuts)
OR (+)	[+] or [Y=]
AND (*)	[*] or [Window]
NOT (!)	[-], [Zoom], or [Sub]
ENTER	Simplify expression
TRACE	Open K-Map (if vars <= 4)
GRAPH	Open Truth Table (if vars <= 4)
DEL	Backspace
CLEAR	Clear input / Back to Dashboard
2nd + MODE	Quit Program

Compatibility

Tested on TI-84 Plus CE-T Python Edition. Should work on any TI-84 Plus CE model. Please report any issues in the Issues tab.

Building from Source

If you want to modify the code or build it yourself:

1. Install the CE C Toolchain.
2. Clone this repository.
3. Run make in the root directory.
4. The output file will be in bin/LOGiCE.8xp.
