These files are for the TI-84 Plus CE, 83 Premium CE, and other "CE" calculators with color screens. BASIC programs are compatible with the TI-84 Plus CSE and some BASIC programs written for monochrome 83+/84+ calculators will also work correctly. Assembly and C programs must be written for the CE calculators specifically; running them on calculators with an OS newer than 5.5 requires jailbreaking the calculator.

Many assembly programs for the CE calculators are written in C, and will require a copy of the C libraries on the calculator in order to run.



  1. This neat little program makes your calculator automatically display fractions on the home screen! See the readme for more.

  2. A CE C toolchain library -- for use with LIBLOAD.
    An implementation of industry-standard cryptography for the TI-84+ CE graphing calculator. Contains a secure RNG, Advanced Encryption Standard and RSA encryption algorithms, SSL signature verification, and more. See the enclosed documentation for details.

  4. Test numbers to see if they are a Prime number. If the number has factors (not a prime number), you can view them. Enjoy!

  5. Whether you are a beginner or a master mental calculator, Mental Math is a great program for learning how to compute problems in your head much faster than doing them on paper. Have fun! Version 2.0.1 CE

  6. PineappleCAS is a computer algebra system for the TI-84 Plus CE calculators. It can simplify algebra and identities, evaluate arbitrary precision integer arithmetic, take derivatives, manipulate complex numbers, expand multiplication, substitute expressions, and more. It features a nice GUI and a TI-BASIC interface so that you can use PineappleCAS from within a basic program.

  7. A simple programmer's calculator, with support for basic arithmetic and bitwise operations in hexadecimal, decimal, octal, and binary. Uses an RPN input system.

  8. A real-time converter that lets you enter any of base 10, 16, and 2, and converts it as you type to the other two bases.

  9. Adds commas (or spaces) to real numbers displayed on the homescreen in TI-OS.

    It can also change what character is used as a decimal point.

    Categorized under:
  10. A specialty library for the TI-84+ CE designed to integrate with the C/ez80 toolchain that allows developers to implement encryption, hashing, and encoding into their projects without needing to worry about the low-level implementation.

    Categorized under:
  11. Calculate Pi, using random integers and a gcd function, written in c, with help from MateoConLechuga and jacobly
    v1.3 : Initial Release
    v1.5 : add keyboard interupt with any key
