I believe also that a document like Well, technically it's a split, not a fork; i.e. you don't fork your own code out of yourself. The RTAI 3.x and RTAI/fusion codebases have always been separate, basically because they can't mix properly at core level and pursue different goals. Hence the split. > > https://mail.rtai.org/pipermail/rtai/2005-June/011949.html > > but with Fusion/Xenomai it would be a very good starting point for a > relatively inexperienced user.

Xenomai. RTAI/fusion is dead; all fusion contributors moved to Xenomai. > 2) why the xenomai files are so old (2002) ? Which ones? Those under the attic/ directory? Well, because Xenomai has been founded in 2001, and what you see there are the versions released up to 1.1.1, before the project had decided to merge with RTAI in 2003, in order to produce a pervasive and highly integrated real-time framework for the GNU/Linux environment, based on the initial Xenomai codebase. What we have done is basically a retro-merge, getting back our independence so that we can continue the development effort in a more consistent manner. The next version based on the latest CVS tree from RTAI/fusion 0.9.1 with additional updates will then be 2.0. For the time being, only our development tree (http://gna.org/svn/?group=xenomai) is available since there has been no formal release of "Xenomai reloaded" yet. > 3) I think that a very important PDF file - already present in the past > in www.rtai.org - is missed: the Fusion tutorial with examples. They have been restored there. http://download.gna.org/xenomai/documentation/ They will be referenced by our new website as soon as it is available. > 4) where I can find some Fusion/Xenomai examples, complete of instruction > to compile and link to create standalone applications ? Look at the demos/ directories under the various skins. Some of the PDF documents available from the URL above give more. > 5) how is it possible to use Comedi driver ? Alex did a port of Comedi over RTAI/fusion. It will need to be rejuvenated over Xenomai. > 6) how port xrtailab under Xenomai/Fusion ? Don't know. But if you do know xrtailab enough, you should have more clues than I do regarding the port though. > 7) it is possible use USB device (eg. camera) realtime ? > AFAIK, a generic effort has been started: http://developer.berlios.de/projects/usb4rt -- Philippe.
