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

The TI-Nspire is a graphing calculator heavily updated for a world in the smartphone age. For one, it's not just another 30-year old Z80 design; the CX models sport a powerful 150MHz ARM processor, equal to the Pocket PCs of old.

However, it's true power is hidden behind a wave of security controls and some ineffectual BASIC and Lua scripts. This guide is about installing Ndless and trying out a wave of emulators, programs, scripts, all kinds of things to get you through Calculus class without sleeping.

This guide works with both the original TI-Nspire and the improved CX version. Just note that the CX calcs will be more practical for CPU intensive or color apps like emulators.

• Nspire History - What is the TI-Nspire family?

Note: Your calculator must be at firmware version 3.6 or less to install Ndless 3.1. OS 3.9 is not supported or downgradable yet.

• Ndless 3.6 - Ndless enables allows custom apps to be run on the TI-Nspire using traditional programming languages, like any decent computer. Ndless 3.6 is the latest version, for OS 3.6 and lower.
• Nlaunch CX 3.6/3.1 - Dual-boot your Nspire into both OS 3.6 and 3.1 with this OS switcher. It bypasses all known OS protections on the Nspire.
  • NLaunch 3.6/3.1 - NLaunch for the black and white Touchpad and Clickpad versions.

• Ndless 3.1 - Ndless 3.1 is the legacy version of Ndless. It is meant for OS 3.2.3 and lower.
• Nlaunch CX 3.2/3.1 - The legacy version of Nlaunch, for dual-booting 3.2 and 3.1.
  • NLaunch 3.2/3.1 - NLaunch for the black and white Touchpad and Clickpad versions.

• Ndless SDK - Ndless also provides a nice SDK for developers to work in, packing a nice emulator to boot.

• Nspire Applications - A list of recommended applications, that don't require Ndless.
• Ndless Applications - A list of recommended applications that use the extra power of Ndless.
• Nspire Linux - A small build of embedded ARM Linux created with Buildroot. Works quite nicely, though apps have to be cross-compiled with buildroot.
• PTTKiller - A description of an exploit to defeat Press-to-Test, and instructions for educators to prevent students from using the exploit. No programs offered here.

• Nspire Prototypes - Often on eBay, some dishonest sellers will ship out "Not for sale" prototype units. These are problematic because they cannot be updated to other OS versions. Here are a few links about Critor's research on converting them into Production units.
