= Ndless for TI-Nspire v1.0 =
=============================
What is it?
===========
Ndless combines a computer installer, an executable loader and utilities to open the TI-Nspire
to third-party C and assembly developments.
What do I need to install it on a TI-Nspire?
============================================
- A TI-Nspire CAS or non-CAS
- Windows
- TI-Nspire Computer Link Software v1.3 or above (previous versions not tested)
- An Internet connection for automatic OS download if OS 1.1 is not currently installed on
the TI-Nspire
How do I install/upgrade it?
============================
Users of beta version 1 or 2 should uninstall Ndless before the upgrade (see further).
Other versions can be upgraded directly.
- If you don't have an Internet connection and OS 1.1 is not currently installed on the
TI-Nspire, get it and copy it to 'userfiles\tinspire_1.1.tno' (the .tno extension is
supported by both CAS and non-CAS models)
- Use the TI-Nspire keypad, and connect the TI-Nspire to the computer
- Run install-ndless.bat
- Follow the steps on the screen. Installing Ndless should take less than 2 minutes with
few manual steps.
How do I run an executable?
===========================
Executables have the extension .tns as standard documents.
- Transfer the executable with a linking program to any folder of the TI-Nspire
- Run the executable from the Documents screen
A demo executable is automatically transferred by the installer to the documents folder
'ndless' you may want to try.
How do I uninstall it?
======================
To uninstall Ndless, reboot the OS while holding the Theta key (next to the ON key) when
the clock is displayed. The calculator will perform a full reboot.
What you need to know as a user
===============================
- The Ndless Installer creates temporary files in the documents folder 'ndless'.
You may remove this folder after installation.
- If the TI-Nspire becomes unusable:
* Enter the maintenace menu by reboot it while holding the keys ON+Home+Enter+P until
half the progress bar. To reboot the TI-Nspire, unplug the USB cable, then remove and
put back the a battery.
* Select '2' to uninstall the current OS. Use the Ndless Installer or TI-Nspire Computer
Link Software to reinstall an OS.
- If the Ndless Installer is lost in is installation sequence, restart it. Ndless may get
installed before the end of the second sequence.
- If running an executable from the documents screen displays the following message:
"Sorry. Could not open document '**.tns'", Ndless has not been correctly installed.
Run the installer again.
What you need to know as a developer
====================================
The executable format and conventions are currently being defined and **e to change.
- The YAGARTO GNU ARM toolchain is a good choice for C and assembly:
http://www.yagarto.de
An example of build ** can be found in src\arm\demo\Makefile
- Executables must be position independent: don't use absolute addresses
- Executable files must start with the 4-bytes-long header 'PRG\0'. The utility 'MakeTNS'
available in the tools directory may be used to add this header to a binary file.
- OS functiｏns can be called from the program, see the source code of 'demo'.
- Development information and resources are or will be available on Hackspire:
http://hackspire.unsads.com
Installing Ndless on nspire_emu
===============================
Ndless can be installed on the third-party TI-Nspire emulator 'nspire_emu' with a
specific installation process.
This feature is currently in development and may be unstable.
- Create a new OS 1.1 flash image, run it once with nspire_emu. Choose 'English'
as system language and save the image.
- Edit the file tools\FlashEdit\install-ndless-nspire_emu.bat and set the variables
NSPIRE_EMU_FLASH_IMAGE_PATH and HARDWARE.
- Run install-ndless-nspire_emu.bat and follow the steps.
You should then be able to send executables and run them as on a real calculator.
If you are getting a "System Error" at boot time on nspire_emu, you are out of luck
and should wait for future versions of Ndless with better support (or even contribute
as a developer).
What we hope you will be able to see in the next releases
=========================================================
- Ndless installation on recent OS versions
- A comprehensive development toolchain
- A fully-fledged executable runner, with relocation and library support, an exception
handler, version-independent OS calls, ...
- More stable and user-friendly installation on nspire_emu
- Support for the TI-84+ keypad
- Mac support
Known issues
============
- Sometimes the Ndless Installer cannot remotely reboot the TI-Nspire, but thinks it has.
In such case, navigate in any menu and the calculator should soon reboot and let you
finish the installation process.
Many thanks to
