Yeah well. Currently it's not possible to do software step generation with it, as the latencies are too high. But Ingo says that latency can possibly be brought below 10uS. He already did 13uS with some hacks. So this is where it gets interesting for software stepgen. I see that linux-rt and RTAI have different goals, but I'm just wondering if linux-rt simply isn't just enough for most of the EMC2 uses (in the future when linux-rt fixed their latency issues). So my basic idea is that lots of people could get a working EMC setup (possibly with software stepgen) without installing RTAI. Of course this is all future foobar, as we're still probably years away from a full linux-rt merge into mainline kernels. So for the time being it wouldn't make a difference if users need to install RTAI or linux-rt. Another big advantage is, of course, that we can use the linux APIs in RT code and get rid of some duplicated stuff (PCI device handling etc...). -- Greetings, Michael. ------------------------------------------------------------------------------ Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ Emc-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-developers
