Nspire Ndless - bibanon/android-development-codex GitHub Wiki

Ndless is a system that allows the use of C or assembly programs on the Nspire, unlocking it's full potential.

If you don't already have the software that came with your Nspire, download and install the TI-Nspire Computer Link for free from TI.

Note: OS 3.2.4 cannot be downgraded using this method.

Unfortunately, Ndless does not work on OS 3.2.x.

On the other hand, we can just downgrade to OS 3.1 to get Ndless. TI did not restrict downgrades to 3.1 for some unknown reason. We hypothesize that it was an escape route in case of bugs.

1. Go to the TI-Planet OS archive and download a v.3.1 file with the name of your calculator model.
2. Open the TI-Nspire Computer Link software, connect your calculator, and drag-and-drop the downloaded file to your Nspire.
3. The program will prompt you to update. Just follow the instructions.

2. Open the TI-Nspire Computer Link software, and connect your calculator. Ignore any update dialogs.

3. Create a new folder called ndless inside your calculator.

4. In the link software, open the folder where you extracted the installer to, and enter the calcbin folder.

5. From the calcbin folder, copy the ndless_resources.tns file to the calculator's ndless folder.

{{Warning|Do not remove ndless_resources.tns from the calculator without uninstalling Ndless.}}

6. Find your model in the list below. From the calcbin folder, copy over the update file with the corresponding file extension to install Ndless.

• .tcc - TI-Nspire CX CAS

7. There will be an error on the computer while installing; just ignore it.
