[08:42:29] <mhaberler> psha: re gladevcp: any idea how to handle an HAL_IO pin? the one in question is the has_bit pin http://emc.mah.priv.at/docs-v2.5_branch/html/drivers/hostmot2.html#_watchdog
[08:43:33] <mhaberler> what I'd like to have is connect this to a HAL_IO toggle button, which changes state when the pin is changed externally, and writes if user toggles
[08:43:40] <mhaberler> any ideas how to handle that?

[14:44:16] <skunkworks> neat - what are your plans with that?
[14:46:16] <awallin_> this should drive the cutting simulation. I have a new one which uses OpenGL VBOs which should be faster than the old one.
[14:47:04] -!- JT-Shop [[email protected]] has joined #emc-devel
[14:47:04] <awallin_> the old one was redrawing the entire stock-surface with vtk (this http://www.youtube.com/watch?v=1DAvgLCj_RQ)
[14:49:51] <skunkworks> very cool
[14:54:19] <awallin_> I think mpictor didn't proceed very much with his effort. he was trying CSG operations to subtract the tool from the stock. but it's quite complex and uses lots of memory. this one: http://code.google.com/p/cam-occ/ but I'm using his ideas for accessing the emc2 interpreter

[19:21:16] <moopy> anyone know anything about the pin definition symbols in rt modules?
[19:22:35] <moopy> I have a problem using new compiled module on an older version of emc, don't have the exact error here but its something like pin floatf size different???
[19:23:22] <moopy> do the symbol defs change between releases?
[19:32:49] -!- micges [[email protected]] has joined #emc-devel
[19:41:46] -!- vladimirek has quit [Remote host closed the connection]
[19:44:44] <andypugh> moopy: I think we need the exact error message, but you might need to recompile the new module for the old version. They are kernel modules, and kernel-specific.
[19:48:42] <moopy> the kernel 'should' be the same, only the emc code is different?
[19:49:16] <moopy> I grabbed the emc code from git about a year ago
[19:49:37] <moopy> and its running on the ubuntu 8.04 version
[19:52:09] <micges> it's possible, we changed size of float pin from 'float' to 'double'
[19:53:31] <moopy> I guess that could be it??
[19:53:48] <moopy> if 2.5 is being fixed for release....
[19:54:16] <micges> hmm but git says that change was 3 years ago..
[19:54:21] <moopy> is there any chance someone will add my halitosis code and dhkins.ko rt module into the release??
[19:55:26] <moopy> I may have a very old version of emc, I think it may have been april 2008??
[19:55:55] <moopy> maybe I see if there is a more recent emc on ubuntu 8.04
[19:56:32] <micges> change was added in 11.2008
[19:56:45] <moopy> I very infrequently do installations and I just picked the first boot cd I found, I will have to check
[19:57:27] <micges> yes live cd with 8.04 will have old float pin size
[19:58:09] <moopy> and if I compile new version of emc from git then the float size is changed?
[19:58:24] <micges> yes
[19:59:08] <moopy> is there an emc release of ubuntu 8.04 with the new float size?
[19:59:38] <moopy> I want 8.04 as I am running on a very old PC with 256Mb ram
[19:59:45] <micges> you can compile emc 2.4.6 on 8.04
[20:00:29] <moopy> all extra time and hassle, but I will do that if there are no 8.04 live cds with the new float size
[20:00:48] <moopy> thanks for the info micges
[20:00:55] <micges> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2#Getting_the_source_with_git
[20:01:32] <micges> there is so far only one live cd with 8.04
[20:02:00] <micges> welcome
[20:02:43] <moopy> how long time 2.5 will be released?
[20:04:25] <micges> 2.5 is stable but there isn't specific date yet
[20:05:13] <moopy> any chance I could get my python config system and dhkins.ko module included in the release?
[20:05:52] <micges> please describe shortly what are they
[20:06:37] <moopy> the python script is sort of like stepconf wizard, but it configs all types of stepper config and servo configs
[20:07:32] <moopy> and it uses arbitrary stacked DH parameters so any number of axes are configurable
[20:08:16] <moopy> I think in the dhkins.ko module it is currently hard coded to 16 joints
[20:08:50] <micges> dhkins can be used without your script ?
[20:09:22] <moopy> yes, could be used without, its really just a hacked version of pumakins
[20:09:42] <moopy> but the gui configuration has to use the dhkins module
[20:10:39] <moopy> for some really basic info check : http://www.soundproofingforum.co.uk/halitosis/
[20:11:07] <moopy> I have just recently looked at is again and I found some bugs in that version
[20:11:27] -!- skunkworks has quit [Quit: ChatZilla 0.9.86.1 [Firefox 3.6.18/20110628230241]]
[20:11:41] <moopy> the install script for copying the dhkins code into the emc source tree is broken
[20:12:27] <micges> imo they can't go into release
[20:12:39] <moopy> why not?
[20:12:51] <micges> but you must ask release manager - cradek
[20:13:19] <micges> becouse stable branch got only bug fixed and 'small' changes if they are needed with bugfixes
[20:13:34] <moopy> when is cradek likely to be around?
[20:13:59] <micges> he has about GMT -8
[20:14:11] <moopy> I think the code is almost stable, but it really needs more people to trying and give bug reports
[20:15:09] <moopy> the code has been sitting unused for over a year now, and I don't think anyone has even tried to use it
