Well this is sort of the direction I was hoping to go anyway. I've heard of Xenomai but haven't looked at it. The RTAI system was a package on Debian(Ubuntu) and so I bit. I was disappointed to find out that instead of installing a workable system, the package only installed the source code.
I built the RTAI system packages(using make-kpkg) against vanilla kernel 2.6.24 but have been delaying trying to install because #1 I doubt it'll work since I kind of haphazardly configured the kernel and #2 it probably work till I pray and cuss a lot. Another issue to me is not just getting a hard realtime system going, but some tool to analyze code output from the compiler to tell me its execution time(based upon processor/clock conditions) d On Tue, Jan 26, 2010 at 4:48 PM, Stephen Sinclair <radars...@gmail.com>wrote: > On Tue, Jan 26, 2010 at 3:15 PM, David McClanahan > <david.mcclana...@gmail.com> wrote: > > in the time constraints(aka the 44Khz).
