[04:36:04] <KimK> Such a hard-working buildbot
[04:36:21] <skunkworks> what is the hardware?
[04:39:03] <KimK> Hi Sam. Speaking of hardware, do you have any suggestions for motherboards lately? I've heard Peter talk about his good results lately, I'll check with him too.
[04:42:33] <seb_kuzminsky> skunkworks: it's a kvm virtual machine on an old lucid server
[04:46:48] -!- Audioburn has quit [Ping timeout: 258 seconds]
[04:47:12] <seb_kuzminsky> plenty of room on the hypervisor host since i rm'd the xenomai buildslave images
[04:48:24] <skunkworks> KimK: what are you going to run with it? I have had good luck recently with gigabyte j1800, j1900 mother boards.
[04:48:45] -!- karavanjo has quit [Ping timeout: 252 seconds]
[04:49:00] <skunkworks> there was a xenomai build slave at some point?
[04:50:40] <skunkworks> the J1900 is a quad core celeron
[04:51:07] <skunkworks> The J1900 also has 1 pci slot
[04:51:38] <skunkworks> (I had it running a 5i25 + 7i80 (ethernet) at the same time.)
[04:51:53] <skunkworks> just testing
[04:51:59] -!- swingley has quit [Ping timeout: 244 seconds]
[04:52:34] <micges> skunkworks: you should add 7i90
[04:53:45] <skunkworks> for?
[04:53:57] <micges> J1900 has also EPP iirc
[04:54:00] <skunkworks> oh - sure - it does have a printer port too..
[04:54:30] <skunkworks> and dual nics - but I don't think 2 ethernet boards are supported yet..
[04:54:55] <micges> testing, you should be able to run 5i25 + 7i80 + 7i90 by lcnc without a problem
[04:55:10] <micges> not yet
[04:55:44] <skunkworks> it is unreal how much expansion you can do..
[04:56:03] <skunkworks> micges: what is the max i/o you have used
[04:56:04] <skunkworks> ?
[04:56:42] <micges> let see
[04:57:09] <micges> 5i25 + (7i77 + 7i84) + (7i76 + 7i71)
[04:57:44] <skunkworks> neat
[04:58:53] <micges> 96 outs and 96 in
[04:59:04] -!- il has quit [Ping timeout: 258 seconds]
[04:59:14] <KimK> Just a small (medium?) knee mill, 32" x 16", 3-axis servo (w/ optional Spindle? 4th? 5th? MPG? W/knee?) I don't have a true I/O count yet, but probably not a lot? No tool changer, though. It's currently a Milltronics, but the control is unrecoverable.
[04:59:18] <KimK> I gave up on Xenomai with the release of the recent LinuxCNC ISO. Is there a reason to stick with Xenomai?

[05:05:43] <KimK> micges: Nice I/O count, any problems? Could you tell how much time was taken up (or left over) for the I/O cycle? And was this at a 1ms servo rate? Were you running base thread too, or no?
[05:07:25] <micges> skunkworks: KimK:
http://imagebin.ca/v/1kLScm2aB0uk
[05:07:38] <micges> KimK: no problems, just plug and play
[05:08:35] <micges> got only 1kHz servo cycle, as for time I didn't measure it but there were two sserial which takes 90us each
[05:09:16] <micges> so total was 5 sserial so up to 50% servo cycle was used

[05:12:52] -!- sudobangbang has quit [Ping timeout: 258 seconds]
[05:22:36] <KimK> OK, thanks. And the 90us is a Mesa-determined speed? I have in mind a project which would use 8 now, maybe 16 eventually? So 720us now, 1440us later? (Clearly would have to go to 2ms.)
[05:33:29] <KimK> BTW, nice piggybacking on the 7i84 aux i/o and the 7i71 aux o, it took me a minute to look that up and see how that was done. And the primaries, 7i77 and 7i76, you needed both analog servos and steppers?

[06:27:42] <pcw_home> sserial is about 80/90 usec for most things, added channels dont add much more (maybe a few usec per channel)
[06:30:57] <KimK> Hi Peter. OK, great, so one (or two?) full 7i44's should be less than 720us? (1440us?) That would help.
[06:31:10] <pcw_home> (that is all channels xmit and recv at once so its possible to run 16 channels or more at multi-KHz rates)
[06:32:54] <pcw_home> Yes that 80-90 usec turnaround is non cumulative (but there is a few usec per channel for reading/writing the data)
[06:33:38] <KimK> OK, great, that sounds good. And this is with "default"(?) speeds? Or is this with "clock tweaking"(?) or some such?
[06:34:23] <pcw_home> this is standard (most time is the 4 usec per character time at 2.5 MBaud)
[06:35:50] <pcw_home> it is possible to run most remotes at 10 MBaud which will bring the max times down to ~50 usec
[06:38:57] <KimK> OK. But that should be pretty fast then, does micges time of 500us (give or take) for his (analog servo+piggyback_i/o plus stepper_i/o+piggyback_o) seem right?
[06:39:13] <pcw_home> KimK: I got the Cincinatti I/O rack outputs working (can now blink the Neon lights on a ACO module)
[06:40:09] <pcw_home> No, it should be quite a bit faster
[06:41:22] <pcw_home> I think micges was thinking the sserial response times are cumulative, but they are all done ~in parallel
[06:44:46] <KimK> Re: Cinci, excellent! What did you use for the 12v output driver, open collector something? Reason is, I'm looking around for something for the opposite purpose, a small fast +/- 15V in comparator so I can protect my OpenSourceSniffer Logic analyzer. I made up the physical adapters for the Cinci some time ago, but had to stop when I put a scope on it and saw the (0-12v, wasn't it) swings. Never got back to it, but I'd still like to be
[06:44:46] <KimK> able to look at the protocol.
[06:44:51] <KimK> Oops
[06:46:11] <KimK> s/wasn't it)/wasn't it?)/
[06:46:33] <pcw_home> I just used resistor dividers for input level shifting (only needed for reading data)
[06:47:02] <pcw_home> and 4054s for 5V --> 12V conversion
[06:48:24] -!- kwallace [kwallace!~kwallace@smb-186.sonnet.com] has parted #linuxcnc-devel

[06:50:01] <KimK> I was hoping to have a pot-variable threshold, but resistors *are* cheap, lol.
[06:50:29] -!- swingley has quit [Read error: Connection reset by peer]
[06:50:40] <pcw_home> Ive got rack and card address figured out still some mysteries with control signals, but I can extinguish the IBA fault lights
[06:50:41] <pcw_home> and have the ACO cards Neons counting in binary
[06:52:10] -!- nofxx_ has quit [Ping timeout: 256 seconds]
[06:52:34] <pcw_home> In my case the dividers are local (on my side of a HEF40245? 12 V buffer)
[06:53:59] <pcw_home> You could use a 26ls32 and a 2/1 input divider as a fast 12V receiver with settable threshold
[06:54:23] <pcw_home> Ill send you a IBAIF card when I get a chance

[06:58:22] <KimK> OK, IBAIF, I forgot, is that the Cinci rack card or is that your new card? And if I can get something kludged together to protect my OSS LA, would it help you if I observed a machine running live?
[06:59:37] <KimK> The OSS is said to be able to do protocol analysis, though I haven't tried it.
[06:59:47] <pcw_home> yeah if i could get original timing info that would help
[07:01:27] -!- f1oat has quit [Ping timeout: 272 seconds]
[07:02:19] <pcw_home> the Cinci bus adapter is called a IBA (first slot) the IBAIF is a 50 pin FPGA daughtercard with 50 pin header and DB25
[07:02:21] <pcw_home> connector to Cinci Rack (mainly a 5 <--> 12V level translator)
[07:05:03] <KimK> OK, I'll put together an OSS LA isolator using your suggested HEF40245 driving resistive dividers. Ah, OK, so the IBAIF (IBA InterFace?) is your new one, great! Yes, I'd love to have one, thanks!
[07:05:46] <pcw_home> I thought the I/O cards were bit addressed but they are 8 bit parallel
[07:06:29] <KimK> Yes, 8-bit data, and what, 10-bit address? I forgot.

[07:06:55] <pcw_home> next step is to loop back 8 ACO module outputs to 8 ACI inputs and try reading data
[07:08:40] <pcw_home> there are:
[07:08:41] <pcw_home> 4 RS addresses (rack select - the thumbwheel on the IBA)
[07:08:43] <pcw_home> 4 CS addresses (for the up to 16 cards in a rack)
[07:08:44] <pcw_home> and maybe 3 per card addresses
[07:11:03] <pcw_home> The RS and CS addresses work as expected (card closest to IBA is CS0)
[07:14:02] <KimK> Where CS0 is the "zero/first" card, you mean? OK, great. And for the OSS, how about if I wanted a more generalized +/- 12 (or 15?) fast comparator, so I can pick the slice point with a pot? What would you suggest then? I was looking at some fast comparators, but some limited the speed, compared to the OSS. Some were big and pricey.

[07:16:13] <pcw_home> Its hard to get fast and wide common mode range together
[07:16:34] <KimK> Yes, that's what I was finding.
[07:17:01] <pcw_home> I dont know we usually tack protos on multi up-panels with small production lot cards
[07:17:25] <KimK> OK, I'll ask around.
[07:18:13] <pcw_home> so we only pay about $0.15 per square inch for 4 layer protos but we end up with 50 cards

[15:21:40] <mozmck> Is it an error to connect to a HAL pin that does not exist?
[15:21:55] <mozmck> or will it just ignore it?
[15:23:19] <cradek> halcmd: net what not-a-pin-name
[15:23:19] <cradek> <stdin>:1: Pin 'not-a-pin-name' does not exist
[15:24:38] <mozmck> ok. I'm (finally) working on a component, and it would be nice to have pins created automatically if devices are detected.
[15:25:38] <cradek> yeah I think you only get one chance to create pins at initialization time
[15:25:39] <pcw_home> ifdef halpin {
[15:26:20] <mozmck> I can just create pins and do nothing with them if the device is not present, but that not quite as flexible as what I was thinking of.
[15:26:54] <mozmck> pcw_home: I'm not sure I understand?
[15:27:50] <pcw_home> Ive often wished the hal parsed haf a if_exist hal pin function
[15:28:16] <pcw_home> hal parser had
[15:29:16] <pcw_home> so it could at least bellyache more expressively if something was missing
[15:29:34] <mozmck> ah, yes. my thoughts are probably similar. a hal file could connect pins and nets, and the ones that don't exist get ignored until they do exist, then start using them.
[15:30:19] <mozmck> That might slow things down just a little though. Exactly how is a hal pin implemented? Is it a function?
[15:31:10] <pcw_home> I presume its a pointer
[15:31:55] <mozmck> since a userspace component is a separate process, I would assume it has to be more than just a pointer?
[15:32:15] <seb_kuzminsky> a hal pin is a pointer
[15:32:28] <seb_kuzminsky> into memory shared with the rest of hal
[15:34:00] <mozmck> ah, ok.
[15:35:33] <seb_kuzminsky> in the hostmot2 driver we do all the device detection early, then hal_pin_new, then hal_ready
[15:36:12] -!- anth0ny_ has quit [Quit: anth0ny_]
[15:37:06] -!- nofxx_ has quit [Ping timeout: 264 seconds]
[15:37:15] <mozmck> So if a device is not present, then pins for it don't get created?
[15:37:25] <seb_kuzminsky> right :-/
[15:37:29] <mozmck> Then if the hal file has connections for those pins it fails?
[15:37:33] <seb_kuzminsky> yep
[15:37:36] <mozmck> ugh
[15:38:12] <seb_kuzminsky> i suppose at startup you could create hal pins speculatively, for all the devices you might discover in the future
[15:38:21] <seb_kuzminsky> that way the pins'll be there and you can hook them up
[15:38:39] <seb_kuzminsky> they just wont do anything until the component discovers the device later (if at all)
[15:38:53] <mozmck> Yes, that's my thought, or probably what I'll do is have options passed to the component telling it which devices I want it to make pins for.
[15:39:30] <cradek> I don't understand yet what problem you're trying to solve
[15:39:48] <cradek> you want pins for hardware that might be plugged in later?
[15:39:57] <mozmck> yes.
[15:40:28] <cradek> what kind of hardware setup is making you want that?
[15:40:37] <mozmck> then the hal file can be more staic.
[15:40:40] <mozmck> static
[15:41:32] <mozmck> we have a USB->RS485 hub that talks to our devices.
[15:43:42] <mozmck> it would be nice (I think!) to be able to have a hal file that has connections for many devices - if they exist.
[15:43:46] -!- swingley has quit [Ping timeout: 255 seconds]
[15:45:58] -!- pcw_home has quit [Ping timeout: 256 seconds]
[15:46:00] <cradek> I think I can imagine some times that might be useful - like a probe that you only plug in when you need it
[15:46:05] <mozmck> anyhow, I'm currently just trying to figure out what can be done to figure out the best way to do what I need to do.
[15:46:35] <cradek> if the probe plugs into an opto22, it's fine if you unplug the wire, who cares, the opto22 is still wired to the mesa card and the mesa driver still presents the hal pin to hook up to motion's probe input
[15:47:31] <cradek> but if your probe is much smarter than that - part of a hotplug system like usb - the scheme breaks down
[15:47:42] <mozmck> yes, so I can do it by just have my component make hal pins for everything that might be hooked up, or I can pass in arguments telling it what to create.
[15:48:26] <mozmck> I think the latter may be what I want
[15:48:28] <cradek> yeah I think in the probe case you'd tell the hub's driver "I have the smartprobe device I might plug in sometimes" so it gives you a pin to hook to motion's probe input pin
[15:49:11] <cradek> then you have the same hookup (that is sometimes inactive) as my probe via opto22 setup
[15:49:43] <archivist> if you have a pin but no device you need to set a default state for it maybe
[15:50:02] <cradek> yep
[15:50:24] <cradek> the hub driver should know what an unplugged smartprobe should do
[15:50:45] <mozmck> heh, yes - or you read 398740928 volts on the power supply :)
[15:51:01] -!- pcw_home [pcw_home!~chatzilla@c-50-143-148-115.hsd1.ca.comcast.net] has joined #linuxcnc-devel
[15:51:04] <archivist> or run to a stop with no stop switch
[15:53:46] <cradek> a smartprobe that's unplugged should probably show low (probe is not touching) but a smartlimitswitch that is unplugged maybe should show high (on limit)
[15:54:14] <cradek> I think the hub driver should know these things
[15:55:05] <mozmck> yes, the component will handle all of that - and there's nothing like a limit switch on it, but probably will be relays at some point.
[15:56:09] <cradek> yeah I'm not guessing what your hardware is - just thinking of simple examples to help me picture how the design could work
[15:57:29] <mozmck> right now, mostly a THC, hand controller, and information from a power supply and drives.
[15:58:33] -!- kwallace2 [kwallace2!~kwallace@smb-31.sonnet.com] has joined #linuxcnc-devel
[15:59:36] <mozmck> So for every configuration, I'll need different hal files. Hmm, can you #include hal files in others?

[16:13:58] <seb_kuzminsky> mozmck: yes
[16:14:32] <mozmck> seb_kuzminsky: thanks - that is nice.
[16:14:39] Cylly is now known as Loetmichel
[16:16:26] <pcw_home> ifdef (halipin)
[16:16:28] <pcw_home> #include frimmle.hal
[16:16:29] <pcw_home> endif
[16:18:34] <mozmck> pcw_home: but the ifdef (halpin) doesn't work - right? that would be nice.
[16:18:57] <pcw_home> Yeah its a joke
[16:19:59] <pcw_home> gets a bit ugly if the hardware subsequently disappears
[16:20:49] <mozmck> and the hal pins that go with it?
[16:22:34] <pcw_home> I guess the hal pins could stay if thay were reassigned decent values at least one hal pin indicatd that the hardware is not present
[16:22:47] <pcw_home> and at least

[16:40:04] -!- ejb has quit [Quit: ZZZzzz…]
[16:44:41] <cradek> halpr_find_pin_by_name is already implemented but I don't know if it's supposed to be part of the external api
[16:44:50] <cradek> searching the list of pin names is a common thing hal has to do
[16:45:17] <cradek> I don't understand how this helps you solve your problem, though
[16:46:14] <cradek> ah halpr_ means private
[16:46:20] <cradek> so no, that's an implementation detail
[16:48:47] <seb_kuzminsky> yeah there are two things under discussion here
[16:49:25] <seb_kuzminsky> 1. how to create hal pins for devices that are not present at component creation time?
[16:49:43] <seb_kuzminsky> 2. how to dynamically wire hal circuits based on available pins?
[16:50:58] <seb_kuzminsky> i remember i wanted 1. when i was writing the hostmot2 driver, but ended up working around it by doing all detection at component creation time
[16:51:50] <cradek> I understand the desire for #1 after the smartprobe thought experiment, but I don't really get #2 yet
[16:52:09] <seb_kuzminsky> for 2 we have haltcl, might that be useful mozmck ?
http://linuxcnc.org/docs/2.6/html/hal/haltcl.html
[16:52:31] <seb_kuzminsky> cradek: a situation that wants 2 that i've imagined is this:
[16:53:11] <seb_kuzminsky> we could have example config files that include drivers for hardware that users might not have
[16:53:18] <seb_kuzminsky> such as those usb joystick jogger things
[16:53:26] <seb_kuzminsky> and the xhc-hb04 jog pendant
[16:53:27] <seb_kuzminsky> and others
[16:53:44] <seb_kuzminsky> and a smart/programmable hal file (haltcl maybe) could do something like:
[16:54:03] <seb_kuzminsky> try to load all these optional drivers
[16:55:06] <seb_kuzminsky> for all the ones that succeeded in loading, OR or ADD together their jog pins => axis.N.jog-counts
[16:55:25] <cradek> ah, you're inventing plug-and-play
[16:55:34] * seb_kuzminsky ponders
[16:55:43] <seb_kuzminsky> sort of
[16:56:01] <seb_kuzminsky> 2 is init-time plug-n-play, 1 is part of runtime plug-n-play

[20:05:36] <seb_kuzminsky> francis tisserant (the guy who translates our docs to french) got back to me with positive feedback on the po4a idea
[20:06:17] <seb_kuzminsky> he offered to do the french translation in the new gettext/po4a framework once/if that gets set up
[20:06:43] <seb_kuzminsky> he acknowledged that the structure of the french docs has diverged from the english, and that it would be a hassle to unify them in order to use gettext
[20:07:02] <seb_kuzminsky> but also that that's probably a better option than the current diverged situation
