Linux (TI) Programmer Group


TilEm2 is a free software project licensed under the GNU GPL v3+ (portions are licensed as LGPL or another GPL compatible license).

Our development is “user driven”: you are the most important thing for us (we don't care about money or power.)

New contributors are always welcome; you don’t need to be a programmer (although it doesn’t hurt.) There are many ways you can help:

  • Reporting bugs.
  • Artwork/photography (we are still in need of high-quality background images for some calculator models.)
  • Distribution packaging.
  • Writing documentation, articles and/or tutorials.
  • Sending patches to improve the code.

The current maintainers of TilEm are Thibault Duponchelle and Benjamin Moody (but many other people have played a part in making this program possible). If you’d like to help, please contact us!

Bug tracker

We have an online bug tracker hosted on SourceForge. Please use it to report any problems you encounter with TilEm.


TilEm is developed online using Subversion. If you are interested in helping with TilEm development, or if you just want to try the latest “bleeding-edge” version, you can download it using:

svn checkout tilem 

You can also browse the code via the Web.

Be warned that this code is in active development, and may or may not be working at any given time. If you’re not interested in getting your hands dirty fixing bugs, please stick to the latest official release of TilEm.

Contacting us

We have a forum for TilEm users hosted on SourceForge.

There is also a mailing list where we discuss TilEm development; non-developers are also welcome.
