The first program, ndless!

The first program I’ve decided to post about is one for the Ti Nspire family. It’s called ndless, and can be found here at the developers blog or here at What it does is it allows third party access to your nspire, allowing you to code in C or ASM on the calculator!

Firstly, download the latest version of ndless and make sure it’s compatible with your OS. If you have OS 3.2 or greater, go here to see how to fix that. Next, create a folder on your calculator called ndless and drag ndless_resources.tns and ndless.cfg.tns into it. Now, drag your corresponding OS to the calculator. After transfer, the installation bar won’t fill up all the way. That is completely normal. If everything goes as planned, on your calculator will be a small message saying you’ve installed ndless!

Ndless files/abilities


If you create a folder inside your ndless folder called startup, whatever program inside will run on boot.


Allows you to change settings for various ndless programs. To edit it, rename it with the extension .txt


Will uninstall ndless. Don’t touch if you don’t want this to happen. DO NOT DELETE WHILE NDLESS IS INSTALLED.

ndless SDK

Write programs for ndless with ndless C available through this dev kit! Allows you to test and build your own programs to be converted into .tns format for the nspire.
