00:00:04 and you want to do that in hardware that takes an analog input, and outputs pulses at a proportional frequency? 00:00:20 i was thinking digital input, but yeah 00:00:29 ok - a numerical input 00:00:30 via EPP 00:00:48 fine - and it provides a count of pulses output as its "feedback" 00:00:56 yep 00:01:13 well. that sounds a lot like the USC 00:01:22 ah is that what it does? :) 00:01:25 yep 00:01:34 except that it can also take encoder inputs 00:01:46 and has 8 digital outputs and 16 digital inputs 00:01:57 and supports 4 axes 00:01:59 (per card) 00:02:59 it doesnt actually have any driver electronics 00:03:27 no - it's not a driver, it's a step and feedback generator 00:03:54 seems like a lot of money for that 00:04:08 $250 isn't all that bad. 00:04:18 depends what you're doing with it 00:04:19 it's more than a DIY board would be 00:04:33 yeah i thin i could make something like that for maybe $10 00:04:44 heh maybe not $10 00:04:51 for me, I have motors that the Geckos can run at around 1800 RPM (30 RPS), they have 4000 count encoders 00:05:09 that's 120 KHz, so there's no computer made today that can do that 00:05:38 are these steppers or servos? 00:05:43 if I use Rutex or some other high voltage drive, I can get that to 2500 RPM 00:05:45 serrvos 00:05:47 servos 00:05:53 serrrrrvos 00:06:57 too bad theres not cheap quadrature decoder chips 00:07:03 yeah 00:07:24 you can buy a dsPIC with built in hardware decoders for the price of a standalone decoder 00:07:33 I'm hoping there's some really weird problem with decoding quadrature encoders, because the logic to do it is worth about $0.30 00:08:04 from what i've heard there isn't any really weird problem 00:08:12 I thikn jitter can be odd 00:08:25 also, you have to be sure that you latch the count when a read occurs 00:08:51 hmm i was just thinking step and direction 00:09:04 that's not quadrature 00:09:16 right that's the point 00:09:27 err - which point? 00:09:32 it doesnt matter, nevermind :) 00:09:35 ok 00:10:04 i'm still learning about how to use microcontrollers 00:10:18 so some of my ideas are a little off 00:10:56 of course 00:11:01 I mean - really. hmmm :) 00:11:21 ahh...just back from BK...tummy full of msg. 00:11:34 MSG laden grease? yummy 00:11:45 yeah 00:11:53 i prefer my msg in its natural state - soy sauce 00:12:10 I was sick and had not eaten much today or yesterday.

As a result, Microsoft must make available a revised version of these products with the allegedly infringing code replaced. 16:22:49 16:23:24 Action required: 16:23:24 16:23:24 As a result of the above ruling, you are required to: 16:23:24 16:23:24 Install Microsoft Office 2003 Service Pack 2 (Office 2003 SP2) for all your future deployments of Office Professional Edition 2003 and Office Access 2003, 16:23:25 so what's the punchline?

20:24:52 well.. actually I'm wondering how I can cd to a dir inside a makefile 20:27:26 you want it to automatically traverse the directory tree? 20:29:00 no, I want it to cd into the src/ dir, and start another make there 20:29:35 and I tried 'cd src/' and on the next line $(MAKE) 20:29:39 but that doesn't work 20:30:22 likewise 'cd src/ && $(MAKE)' make is starting, but it's in the wrong directory 20:31:46 try including it as an include file 20:31:50 or however you say that 20:32:01 no, I need to be in the exact dir 20:32:11 because that makefile in there is using relative paths 20:33:02 try -C dir ? 20:33:15 tried, but it keeps getting out of that dir 20:35:43 (cd src; make $@) ? 20:36:21 hang on.. trying now 20:41:32 nope.. same issue 20:41:52 oops.. no, wait 20:42:00 it's good, differnet issue now :D 20:43:27 that doesnt make sense 20:43:35 no, what you said works 20:43:52 I'm getting another error now, and I thought it's still the first one 20:44:09 i mean it doesnt make sense why $(MAKE) doesnt work but "make" does 20:44:21 I still used $(MAKE) 20:44:31 but (cd src; $(MAKE) ) 20:44:39 instead of cd src && $(MAKE) 20:44:57 maybe the parentheses are what does it 20:50:18 ok. it seems to work now ;) 20:50:21 thanks a lot 20:50:43 that's what's in the emc top level makefile 20:51:24 hi SWP_Away 20:51:27 hi 20:53:39 03alex_joni * 10emc2/src/Makefile: changed the Makefile accordingly to the move of files lately, config/ and the new runscript. this affects only make install rule 20:58:33 petev has joined #emc 21:19:09 03alex_joni * 10emc2/debian/ (changelog control copyright rules): helper files to create an emc2 debian package. just issue 'fakeroot debian/rules binary' from emc2/ 21:27:34 dmessier has quit 21:29:14 TorbaX has joined #emc 21:43:00 03alex_joni * 10emc2/configs/motenc/ (README motenc_io.hal): added some more comments 22:10:09 03petev * 10emc2/configs/motenc/README: -Changed Motenc to Motenc-100 for clarity. 22:15:57 logger_aj has joined #emc 22:15:58 topic is: Welcome to the Enhanced Machine Control forum - Support and development of a linux based CNC control. | Home: www.linuxcnc.org | Regular Developers' meetings every Sunday 14:00-18:00 GMT | wiki up @ http://wiki.linuxcnc.org | EMC usage map: http://www.frappr.com/emctheenhancedmachinecontroller 22:15:58 Users on #emc: logger_aj TorbaX petev roltek Jymmm wb9mjn LawrenceG thalx CIA-14 SWP_Away cradek fenn [g2] jtr_ alex_joni Sed_ ccjoe robin steves_logging Timbo A-L-P-H-A websys lerman jepler ValarQ @ChanServ 22:31:05 djb_rh has joined #emc 22:35:32 petev has quit 22:57:42 <|florian|> |florian| has joined #emc 23:01:29 <|florian|> |florian| has quit 23:12:55 Jacky^ has joined #emc 23:13:19 halo 23:16:30 ilovebees 23:16:52 hey fenn :)) 23:17:34 saturday night fever ?
