  4. TI-84 Plus CE BASIC Programs

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.

  1. This program is unlike other quadratic solver, you don't have to type the variables in separately, all you have to do is type in a Quadratic equation. You don't even have to know what the variables in the form ax^2 + bx + c are. All you have to do is copy down whats in your math book. This gives you the roots of the equations, which variables are which, and the vertex of the equation. Have fun!

    PS(for Americans): Don't use this on the ACT! If you are caught you will be banned from taking it again!

  2. With this program written in TI-BASIC you can calculate the day of week for any given date!

    When you try to calculate on what day of the week a date was using the DayofWk( command, you might have noticed that the answer wasn't correct.
    I don't expect you'll have seen that though, but I've tested it with several dates and I can tell you it isn't correct.
    If you want to know more about this, you can read the 'readme' file.

    I've in this program made a settings part, in which you can set everything for your country.

    I really want to thank one of my classmates, who can calculate a day even out of his head, also for the Julian calendar.

    current version: 1.2.2

    Notes:
    -I really recommend checking the 'lite' version of this program if you want a smaller one: http://ceme.tech/DL2066
    -There are some important notes for some country's noted in the 'readme' file!

  5. The Calendar and Task Sorter is a program that allows you to see a calendar for any month and year that is entered into the calculator. Program will always default to the current month and year the calculator is set for. Tasks can be entered into the calculator and reminders can be set to remind you the day the task is set for. Task reminders will appear when the program is run. A manual and date calculator is included in the program. This program is written only in basic.

    Categorized under:
  6. This program will calculate for: Power (P), voltage (V), resistance (R), current (I), and Reactance.
    It is able to calculate those using only two known values depending on what you want calculated.

  7. Update 3.42! Tank Duel is a 2-player turn-based game where each player takes turns
    shooting at the other player's tank. Includes random terrain generation, terrain options,
    terrain destruction, three types of bullets, different tank colors, health and movement
    options, and realistic physics. A more streamlined menu is now included.

  10. Backstory: I downloaded an ECG program produced by Kerm Martian, which simply put 5rand & -5rand in Y1 and Y2, which is a major code saver, but it looked horribly unreal. I decided to make a pretty and generally realistsic (every line crosses the x-axis, and every line is connected)
    (Does NOT require Doors)

  12. This is a program that tracks the amount of rolls of coins you have as you roll them. A good program for someone dealing with a lot of coins during the day.

    Categorized under:
  13. It's a memory game that tests your memorization skills. This is one for the TI-84 Plus CE, and it's written in only TI-Basic! The object is to make it as far as you can without making any mistakes, by reproducing a sequence of flashing numbers via the number keys on your Calculator. Are you up for the challenge? You can even customize the difficulty of your run and learn the mechanics of the game via a built-in tutorial! Newest addition: The game keeps track of the highest round you made it to and you get a rank based on it. How high will you rank in this challenging memory game?

  15. A Friday Night Funkin/DDR inspired game, programmed entirely on my calculator. It's simple and easy to get the hang of, and the addictive gameplay gives you that "just one more try" kind of feel. My first ever big program that I'm super proud of, with updates coming eventually. Please comment with any bugs or anything that needs fixing, and maybe some ideas of stuff to add.

    UPDATE: 1.2.0 is here! Added story mode, high scores, more of Dancing Guy, and other small details you just have to find (or check out the ReadMe.) A lot of stuff was either moved to the ReadMe or removed altogether, so there's more content for not a lot more storage taken. I may be biased, but I still think that this game is truly something awesome.

    I found a bug literally the day after I updated this, sorry. It should be working now.

  16. This is a game I made that can teach you to quickly convert between binary and decimal numbers. Read the readme for more info. Version 1.2

    Categorized under:
  17. A fast yet simple encryption/decryption engine written in Basic

    Categorized under:
  18. This is a program that makes the calculator display incorrect results for calculations inputted. Use this to prank your friends. I do not take responsibility for those who abuse this and mess up others tests.

    Categorized under:
  19. A lot more info in the readme (that you gotta read). Help T run away from the F. Use the arrow keys to move. Press enter to pause. Press clear when you are in the top left corner to send the F to the bottom right. If you have a TI-84 Plus or 83, just download the versions you find in the "TI 83/84" folder. "Nate Rivers" is a pseudonym.

  20. This is a simple program to align text in different ways. In custom alignment mode, pressing 1, 2, and 3 are hotkeys for different alignments. When you run the program, select an option (I recommend custom alignment because it allows you to move the text with the arrow keys) and then enter your text. Good for programmers who get annoyed trying to decide on the second argument for Output(.

  21. Word Sort is a game that gives you randomly scrambled letters and you have to find different 3, 4, 5...
    letter words that can be made from those scrambled letters. This download contains 50 levels for monochrome calculators and 60 levels for color calculators, both split into programs with ten levels each!

    Check again for future levels in the foreseeable future.

  22. A very simple program that does exactly what it sounds like it does. This program has you select the colors of
    the bands on a resistor and then it tells you what the resistance, tolerance, and temperature (for 6 band resistors)
    is of a resistor with those color bands. This program works for 4, 5, and 6 band resistors. This program will also,
    automatically convert the resistance number into Ohms, Kilo Ohms, or Mega Ohms. A very simple and easy program
    to use.

    Categorized under:
  23. The classic strategy board game OTHELLO, now on your calculator. 2 player, no computer opponent. The program will report invalid moves, keep score, and update the board automatically. Read the README.txt file for more information.

    Categorized under:
  24. Minimum OS: 5.3.0 (5.2 might work)
    A Wikipedia article and the readme file can better explain this. This program simulates a Reverse Polish Notation calculator that computes more basic math in a different way. Example: "5^2=" would be "[5][Enter][2][^]". Or "2+3+3" would be "[2][Enter][3][Enter][3][Enter][+][+]".
    Supports many statistic variables, constants in math and scientific constants! Download it today and have fun with it!

  25. A very simple program that does exactly what it sounds like it does. This program simply has you enter in the three
    numbers and the letter(s) (i.e. 103K or 3R3K) that are shown on a disc capacitor and the program will find the value of that capacitor.
    A very simple, easy, and useful program to have.

  26. A demonstration of "Evolution" in the TI-84 PCE. See tinyurl.com/linevolution for details!
    UPDATE: Use expression evolution, as it is much more polished and is nearly 120 times faster.

    Categorized under:
  27. This program is for Biology/ science students who need to quickly convert a sequence of DNA nucleotides to a complementary strand or a strand of RNA. It has many features, see the Readme. This has not been tested on the 83+.

    Categorized under:
  28. Contains 2 programs that will help with the cleanup of TI-BASIC programs. These were written by me because I used a few routines a lot, and the use of a sub-program makes the main program smaller. The readme contains more instructions on the use of these programs.

    Updated Subprograms so that they don't graph anything when the program is running. Also removed Labels...

    If you have any suggestions, or things you would like to see done, just ask me! (PM or a review on Cemetech.net is the best way)

  29. This is a program for the TI-84 Plus CE that makes doing cosecants, cotangents, secants, arccosecants, arccotangents, and arcsecants much easier. Cosecants, cotangents, and secants (+ their inverses) are not readily available on the TI-84 Plus CE, instead you have to enter 1/sin(x) for csc(x), sin^-1(1/x) for arcsc(x), and etc. While the aforementioned method is possible, it may get a little tiring when calculating many values in rapid succession at a time using csc, cot, and sec (+ their inverses). This program makes it easier as it gives you a menu of those 6 functions and allows you to calculate them.

    The Program is called "CSCTRIG"

    Works in both Radian and Degree Mode.

  30. This program originally displays a randomly
    moving character on your homescreen.
    Because a simple moving character is boring
    I made some interesting versions of it and
    put them togheter in this program.
    This version is faster and shorter than
    the last one and takes less memory!

  31. This, this is art. ASCII art.
    Welcome to ASCII Slots, where you enter a magical land that's all text based... and ugly.
    I mean, it looks good, but.. yeah, I better get to the features.

    This bad boy packs animations, payouts (in the readme file), and real slot action. It's just like Vegas, except it's text based.

  32. Kerm Martian's Cemetech logo drawing program, ported to the color screen calculators by me, SM84CE. This program will draw the Cemetech logo on to your graph screen. See readme for more detail and credits that explain who did what.
    Doors or Cesium is NOT required to run this. Updated Subprograms so that they don't graph anything when the program is running.

    Feel free to post feedback here or in this thread: https://www.cemetech.net/forum/viewtopic.php?t=14115

  33. PLATFORM is a platformer for the TI-84+ CE and related calculators.

    In it, "e" must traverse a series of serpentine passages in order to reach the square.

    This BASIC program contains the main program, two subprograms, and a supplementary program that contains extra levels.

    Instructions are provided in the "readme" text file.

  34. This Hybrid-Basic program allows you to generate passwords for anything you want! Not only does it generate passwords, it reliably recreates them after typing in the same username + website/thing name. This program REQUIRES TextLib v1.12 by DrDnar Other versions may or may not be supported.

    Categorized under:
  35. This program is used for drawing and exporting 16*16 sprites for use with Sprites_v3.3 (I DO NOT OWN THIS PROGRAM), but can also be used to make sprites for other Hybrid-Basic programs.

    Categorized under:
  36. Yet another TI-BASIC snake game for the Ti84CE calculator.
    This was my first project on the calculator, which I coded fully on the device itself.
    Though the game lags quite a lot after a while, it is still a surprisingly effective time-waster.
    The game includes all instructions, and it can store your hi-score.

    As I made this a while ago and I do not consider it special, it will be released under the WTFPL v2 license.

    Categorized under:
  37. Uses the TI-83+/TI-84+/TI-84+CE built-in atan2() function to calculate the arc tangent of a function of the form tan(a) = y/x. Result will be in the correct quadrant.

    Categorized under:
  38. This is a program that can solve for any real triangle and graph it.

    Note: Due to the use of color variables, it is unlikely to work on calculators with non color screens (TI-84+/TI-83)

    Previous Features:
    1. Will solve for any real triangle
    2. Works in both degree and radian modes
    3. Will detect if 2 SSA triangles are possible and will solve for both
    4. Any non real triangle will result in an error message
    5. Includes "Help" section on the second page that explains how to use it
    6. 2 graphing modes, the first will fit the triangle to the screen, the second will graph it to scale

    New features/Improvements:
    1. Will solve a triangle based off of 3 coordinates
    2. Fit/to Scale is now automated but can be changed manually if needed
    3. Program runs a little bit faster when switching between graph and stats screen
    4. If altitudes are needed, a 3 coordinate triangle can be graphed as a standard triangle
    5. Program now runs off an array list instead of variables meaning it will not overwrite current variables and the "show last triangle" feature should work more often
    6. Key to array list slots included in code
    7. Bug fixes

    If there is anything that needs to be fixed/improved or you have made a better version, feel free to comment.

  47. This is a BASIC program that takes up to 9 different unknowns and solves for each unknown. The equations can be complex numbers, which allows the user to solve for systems such as those in time varying current circuits. Uses matrices to solve the equations, and may take large amounts of RAM when dealing with many unknowns, (around 3500 Bytes). CMPLXEQN.8xp is the main program and works by itself. If the calculator is not updated to OS 5.2 or is not a CE, then CPLXEQ84.8xp should be used.
