[03:40:46] <garage_seb> goodnight chris
[03:41:04] <SWPadnos> no. I may be thinking of a different xkcd.
[03:41:18] <garage_seb> http://xkcd.com/936/
[03:41:22] <SWPadnos> the song is "Hammers on the shore", by Peter Schilling (hammers being the operative part)

[06:29:21] <psha[work]> mhaberler: around?
[06:29:30] <mhaberler> yessir
[06:29:50] <mhaberler> what's cooking?
[06:31:40] <psha[work]> latex equations in html
[06:33:12] <mhaberler> uh. poort thing. Making png's?
[06:33:48] <psha[work]> yea ;(
[06:34:13] <mhaberler> how's the chance of that working?
[06:34:47] <mhaberler> I mean I rather read coredumps with od -cx than write latex ;-)
[06:35:07] * Jymmm chuckles.
[06:36:07] <psha[work]> working
[06:36:08] <psha[work]> :)
[06:36:45] <psha[work]> that's why i'm asking here
[06:36:51] <psha[work]> need some review
[06:37:10] * Jymmm review... It sucks. NEXT!!!!!!!!!!!
[06:37:25] <Jymmm> psha[work]: ;)
[06:37:29] <psha[work]> :D
[06:37:53] <mhaberler> based on v2.5_branch?
[06:37:56] <psha[work]> yes
[06:38:00] <psha[work]> that's simple script
[06:38:32] <mhaberler> look: every time you use the word 'simple' in a sentence, I dont get away under three hours ;-)
[06:38:50] <mhaberler> ok, so. branch?
[06:39:04] <psha[work]> not yet
[06:39:07] <psha[work]> running testbuild
[06:39:14] <mhaberler> wonderful!
[06:39:14] <psha[work]> it's post-processing script for html
[06:39:25] <psha[work]> so it's not affecting compilation process
[06:39:44] <psha[work]> except small config which wraps every equation in <span class='latexmath'>
[06:39:54] <psha[work]> so later it's possible to select them and replace
[06:40:33] <mhaberler> 'small config': is that a change to source documents?
[06:44:18] <psha[work]> xhtml11.conf -0/+1
[06:44:25] <psha[work]> xhtml11-images.conf new file
[06:44:27] <psha[work]> oos
[06:44:31] <psha[work]> xhtml11-latexmath.conf
[06:44:52] <psha[work]> btw probably we need extra configure flag for doc languages :]
[06:48:18] <psha[work]> with defaults to en + ${LC_ALL%%_*}
[06:49:03] <garage_seb> great!
[06:52:35] <mhaberler> psha: when done, I'll merge your branch and push docs to emc.mah.priv.at/docs so folks can have a look
[06:53:22] <psha[work]> http://psha.org.ru/emc2-docs/common/User_Concepts.html#_planning_moves
[06:53:30] <psha[work]> please take a look
[06:55:04] <mhaberler> not bad vs 2.4 html: http://www.linuxcnc.org/docs/2.4/html/common_User_Concepts.html
[06:56:37] <mhaberler> can the png's be made an achor so we have a link page to step through all latex pix for review?
[06:57:21] <mhaberler> to make sure all are caught and easy to view
[06:58:25] -!- moopy [[email protected]] has joined #emc-devel
[06:59:06] -!- capricorn_one has quit [Remote host closed the connection]
[06:59:21] <psha[work]> hm
[07:02:24] <mhaberler> it's this quality-control fad ;-)
[07:04:36] <mhaberler> garage_seb: do you have an opinion on the watchdog issue I mailed yesterday? I think it is at the very least very confusing and potentially dangerous (watchdog says ok when no signal?)
[07:05:57] <psha[work]> mhaberler: all formulas are stored in cachedir
[07:06:21] <psha[work]> so it's possible to look trough every generated image by simple browsing
[07:06:27] <mhaberler> that's good, but to review them you would want to see them in context
[07:10:13] <psha[work]> that's harder - since they may be shared between docs

[07:14:37] <psha[work]> also we need some sort of css rules for latexmath images
[07:14:58] <psha[work]> my asciidoc installation is totally broken :]
[07:15:11] -!- moopy has quit [Ping timeout: 245 seconds]
[07:25:49] <garage_seb> mhaberler, did you send me an email? i dont see one. or do you mean on the vfd thread?
[07:26:06] <mhaberler> no, on emc-developers
[07:26:21] <mhaberler> but since you're familiar with hardware I though I'd ask you
[07:27:22] <psha[work]> ofound, fixed
[07:27:33] <mhaberler> 'watchdog.9 observed vs described behaviour'
[07:27:51] <psha[work]> i'll push branch shortly
[07:28:03] <mhaberler> ok
[07:28:34] <mhaberler> psha: do you have emc box at work now?
[07:29:18] <garage_seb> mhaberler, i dont see any email like that from you yesterday
[07:29:19] <psha[work]> no
[07:29:24] <garage_seb> maybe sourceforge ate it?
[07:29:33] <mhaberler> ah...
[07:29:35] <mhaberler> wait
[07:29:37] <psha[work]> http://thread.gmane.org/gmane.linux.distributions.emc.devel/4865
[07:29:41] <psha[work]> this one?
[07:30:29] <mhaberler> yes, that's the one
[07:31:44] <mhaberler> 2 (e) is a potential killer bug
[07:32:13] <garage_seb> oh yeah, there it is, i see it
[07:32:37] * garage_seb reads
[07:33:48] <garage_seb> yeah, 2c and 2e sounds totally broken
[07:33:59] <psha[work]> http://psha.org.ru/cgit/psha/emc2.git/commit/?h=asciidoc-latexmath
[07:35:04] <mhaberler> I was wondering how to fix this; first, I think out-ok should always stay low until signal proven present, not assume present until absent
[07:36:47] <mhaberler> second, the enable logic needs clarification wether its level or edge triggered; manpage unclear
[07:37:16] -!- ries has quit [Ping timeout: 245 seconds]
[07:38:06] <mhaberler> the best solution IMO would be to have a "enabled" out pin, and make sure out-ok never goes high if no signal present
[07:38:13] <psha[work]> mhaberler: compilation failed on one file
[07:38:23] <garage_seb> i agree with the first part, that out-ok should be low until a good input signal is seen
[07:38:31] <mhaberler> ok
[07:38:53] <garage_seb> i think cycling enable-in is a reasonable way for the rest of the logic to signal "i'm ready for you to start being a watchdog again"
[07:39:27] <mhaberler> so that would mean positive edge on enable-in arms watchdog, which I think makes sense
[07:40:05] <mhaberler> but then it stays armed if the enable-in goes low again
[07:40:08] <garage_seb> right
[07:40:12] <mhaberler> ok
[07:40:16] <garage_seb> wait no
[07:40:31] <garage_seb> i meant "right" for the first part, that pos edge on enable arms it
[07:40:44] <mhaberler> any action on negative edge?
[07:40:45] <garage_seb> but i think if the user brings enable low, the watchdog should stop being a watchdog
[07:40:59] <mhaberler> but then it needs to disable out-ok
[07:41:11] <garage_seb> i dont know if that means out-ok becomes disabled or just undefined
[07:42:25] -!- theos has quit [Read error: Connection reset by peer]
[07:42:38] <mhaberler> well, using out-ok naively as I did spells trouble
[07:42:59] <garage_seb> that manpage is pretty confusing
[07:43:14] <psha[work]> mhaberler: amended
[07:43:18] <mhaberler> it probably needs anding with enable-in to go high at all, besides positive signal
[07:43:22] <garage_seb> maybe ask SWPadnos what he meant?
[07:43:37] <mhaberler> he's around then?
[07:43:43] <mhaberler> will do
[07:44:15] <mhaberler> psha: any branch, or a commit to pick?
[07:45:23] <mhaberler> psha: a79bc3d2ca47f895eab9139462ebba50d927a38b ?
[07:46:56] <psha[work]> asciidoc-latexmath
[07:47:14] <psha[work]> compiled without errors
[07:47:16] <garage_seb> also, a test would be nice! ;-)
[07:47:17] <psha[work]> nice
[07:47:32] <garage_seb> psha[work], the html equations look great, thank you!
[07:47:36] <psha[work]> 57 unique formulas in source

[12:29:06] <mhaberler> again: to step through them an anchor would be very valueable. could you add that? script is here: http://git.mah.priv.at/gitweb/emc2-dev.git/shortlog/refs/heads/asciidoc-latexmath-test
[12:29:19] <psha[work]> there is anchor

[20:26:49] <andypugh> How much of the incremental encoder interface should an absolute encoder share?
[20:27:14] <andypugh> If, for example, one were writing a driver for the Mesa resolver board?

[21:31:40] <cradek> which level of interface are you talking about? the user api in hal?

[21:33:17] <andypugh> HAL
[21:33:34] <andypugh> ie, what pins should it have, and what should it do with them.
[21:33:53] <andypugh> I think it needs to not wrap, so simply returning angular position is not correct.
[21:34:24] <andypugh> But that is the only thing I have decidd so far.

[22:22:38] <cradek> I think it should have all the pins an encoder does and they work the same way, but additionally it has two added features: an extra pin with angular data somehow, and on power up before index it reports a correct modulo position

[22:23:54] <cradek> maybe rawcounts from the encoder api is already what you want for the angular data?

[22:24:49] <cradek> hm, wonder how many "counts" per rev.
[22:24:55] <andypugh> OK. even "reset" and index-latch?
[22:25:11] <cradek> rawcounts does not change with reset/index
[22:25:39] <cradek> bbl, gotta run
[22:25:46] <andypugh> The underlying hardware is 32k counts per rev.

[23:58:26] <andypugh> Is it unforgiveably lazy to put component data in hal shared memory just to avoid having to kfree it later?
