well, not really -- if part of the goal is to make a small box that can be plugged into "any" PC and made to work in a world where parallel ports are becoming scarce, then this would accomplish that. and EMC itself would gain a lot -- it would have been ported to another architecture, a new driver might have been written (probably for gpio pins, since there would be no parallel port), and the split between "engine" and "UI" would have been made more explicit, both in terms of the build system and the final packaging. in the end you'd have a way of encapsulating EMC into a "device", independent of the host PC (except for display purposes), while still sharing 98% of its code with the current deployment model. migrating large parts of the code to an embedded micro, or to an FPGA, would lose a fair amount of that leverage. (i seem to recall, however, that the RTAI patches may not be as mature on non-x86 platforms. that might be the biggest hurdle. is RT/Linux support still viable?) paul ... > > On 4/23/07, Paul Fox <[EMAIL PROTECTED]> wrote: > > > One 'device-on-a-rope' at least I would find interesting would be an > > > > to be honest, if one really wants a "device-on-a-rope", and wants > > to use EMC, then they should build a small linux system to be at > > the "end of the rope". use something like the gumstix board, or an > > efika (http://www.pegasosppc.com/efika.php), install busybox, an > > RTAI kernel, "headless" EMC, and talk to it using existing remote > > X11 display technology via ethernet. you could do USB networking ... =--------------------- paul fox, [EMAIL PROTECTED] (arlington, ma, where it's 77.9 degrees) ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
