Hello everyone! I got my hands on the TI-84 Evo yesterday and, having a Linux desktop, quickly became frustrated about the new in-browser TI Connect Evo. Even if using Google Chrome, Texas Instruments has restricted access to TI Connect Evo to specifically Windows, macOS, and ChromeOS devices. While I was able to get it running after jumping through some hoops, this prompted the idea to develop an open-source alternative.
Planned features:
Capture screen (already implemented)
Transfer files to and from the calculator
Perform a software update
Exit Test Mode
Supported platforms:
- Windows, macOS, and Linux
Release date:
- May 15, 2026
Current status:
I have successfully reverse engineered the USB communications protocol used by TI Connect Evo and have written a PoC Python script that captures the calculator's screen by simulating the packets sent by TI Connect Evo and parsing the calculator's response. This will be expanded soon to include all functionality currently in TI Connect Evo, and will feature a much nicer Tkinter GUI.
I will post here as I have more updates to share. Thank you!
