How to install

Get your program onto the calculator.

You generated a .py file — now you need to send it to your TI-84 Plus CE Python. This takes about two minutes the first time, and about ten seconds every time after that.

  1. 1

    Install the transfer app

    You need TI Connect™ CE on your computer — Texas Instruments' free desktop app that talks to the calculator over USB. Pick your OS:

    macOSTI Connect CE · freeWindowsTI Connect CE · freeLinuxTILP II · open source

    TI Connect CE doesn't officially support Linux — TILP II is the community standard and ships in most distro repos (apt install tilp2, brew install tilp2, etc.).

  2. 2

    Plug in the calculator

    Use the USB-A to Mini-B cable that came with your calculator. Connect it to your computer and turn the calculator on. TI Connect CE will detect it in the left sidebar within a few seconds.

  3. 3

    Drag the .py file into TI Connect CE

    Open the app. Drag your downloaded .py file from your Downloads folder straight into the center pane of TI Connect CE — or click Send to Calculator and pick the file.

    Press the Send / upload button. The transfer takes a few seconds. Done.

  4. 4

    Run it

    On the calculator, press prgm, arrow down to the Python submenu, pick your program, then press enter twice. The program runs natively on the calculator — no internet needed.

Troubleshooting
  • Calculator not detected? Try the cable that came with the calculator (cheap USB cables are often power-only). Restart TI Connect CE.
  • Wrong calculator? Python programs only run on the TI-84 Plus CE Python edition. The plain CE and the older Plus support BASIC only. Check the back label.
  • Still stuck? The support chat is monitored — Tommy reads every escalated ticket personally.
