[00:04:21] <JesusAlos> do you know wy EMC2 use 3 kind language programming?
[00:05:19] <andypugh> Because you can't write kernel drivers in Python, but you really don't want to be writing graphical user interfaces in C.
[00:07:57] <JesusAlos> and c++?

[00:12:29] <andypugh> It's harder to explain the TCL, and there is a User interace out there in freePascal.
[00:14:31] <andypugh> To a certain extent developers write in the language they know.
[00:14:52] <alex_joni> there was a java interface
[00:14:58] <alex_joni> and some perl scripts
[00:16:04] <alex_joni> I think there was even a html interface
[00:16:27] <andypugh> MiniEMC uses a web interface
[00:16:43] <andypugh> (that's the semi-embedded version from Russia)
[00:17:11] <andypugh> This is Free software, it's anarchy
[00:17:55] <alex_joni> mix it up ;)
[00:18:57] <JesusAlos> interesting miniemc

[00:38:51] -!- gmagno has quit [Quit: Enough small talk...]
[00:41:24] <jdh> no smalltalk interface
[00:41:54] <andypugh> We need a GUI written in APL and HAL drivers in COBOL too.
[00:42:41] <jdh> I won $100 in a cobol programming contest once.
[00:43:05] <andypugh> I have a mate who wins about $100,000 a year from it
[00:44:52] <andypugh> I have only been paid to code in two languages, Sinclair BASIC and LabView.
[00:45:17] <jdh> US dollars?
[00:45:41] <andypugh> Well, he is paid in UK £ bit he is moderately well paid
[00:46:02] <jdh> could do better than $100k probably
[00:46:13] <andypugh> (I think both surviving COBOL programmers are)
[00:47:09] <jdh> I know one who contracts through IBM. She works for a few months, they pay all expenses, then she lives in north florida and dives for 6 or 8 months then repeats

[00:47:50] <andypugh> That sounds awful for her :-)
[00:48:06] <jdh> she is one of the weirdest people I've met.
[00:48:21] <andypugh> I don't suppose she cute and gullible as well as rich?
[00:48:40] <jdh> 60 or so and male like.
[00:49:41] <andypugh> Must be a COBOL thing: http://en.wikipedia.org/wiki/Grace_Hopper
[00:50:32] <jdh> I did pdp-11 macro today for while today. Turned out the real problem was worn out brushes in a DC motor.
[00:52:25] <andypugh> I was using a PDP-11 at work 3 years ago, but they retired them last year.
[00:52:58] <Tom_itx> you mean you dont get paid to write mesa drivers??
[00:53:00] <Tom_itx> :)
[00:53:37] <jdh> I'm down to two. When Maint/etc gets stuck, they say "must be a computer problem"
[00:53:50] <andypugh> I don't get paid to do anything LinuxCNC related and strenuously avoid any offers to do so.

[02:17:07] <r00t4rd3d> the only bird you know is attached to your hand
[02:17:54] <jdh> that's not true.
[02:18:39] <r00t4rd3d> this school teacher I know is selling mad shit of mine at her school
[02:19:07] <jdh> got any craft show things up there?
[02:19:20] <r00t4rd3d> i was invited to one in November
[02:19:32] <jdh> you are in NY somewhere?
[02:19:41] <r00t4rd3d> yeah
[02:20:09] <jdh> my aunt lives in some artsy place up there. naples?
[02:20:25] <r00t4rd3d> not near me
[02:20:35] <jdh> she's a whackjob... guess it make her happy though.
[02:21:23] <r00t4rd3d> is she single?

[02:22:34] <jdh> if you have a thing for old starving artists, I can hook you up in a year or two.

[02:24:03] <jdh> heh... she is an 'artist'
[02:31:07] <andypugh> Some artists are really quite well off.
[02:31:17] <jdh> yeah, they are probably good though.
[02:33:28] <jdh> she does mostly metal sculpture stuff. I think it looks cool, but not really much to make a living at, especially in naples, ny
[02:34:59] <andypugh> I think Tracy Emin is pretty well off, and her stuff is horrible.

[15:56:08] <pcw_home> JT-Shop: thats the field I/O so different channel now
[15:56:32] <pcw_home> At least I think it is different
[15:57:14] <andypugh> Ah, pcw_home, do you anticipate ever using ScaleMin and ScaleMax for data types 0x04 and 0x05?
[15:57:31] <andypugh> (ie, non-vol data)
[15:57:50] <pcw_home> Yes its possible
[15:58:39] <andypugh> I was thinking about using them for the max current and simialr with the 8i20.
[15:59:20] <andypugh> (so, if they are both non-zero the (read-only) parameter becomes a float not an int)
[16:00:59] <pcw_home> I think that makes sense (but is a little funny for things that are pure integers like baud rate selectors)
[16:01:49] <pcw_home> probably we will leave scalemin and scalemax 0 for these things
[16:02:03] <JT-Shop> field I/O power?
[16:02:21] <JT-Shop> I wonder if it is related to my limit switches somehow
[16:02:41] <pcw_home> Maybe, do you have both the 7I77 and 5I25 jumpered for external 5V?
[16:02:48] <JT-Shop> yes
[16:03:13] <JT-Shop> it happens randomly during homing
[16:04:32] <andypugh> pcw_home: OK, I will just leave it as it is.
[16:04:35] <pcw_home> Looks like something loose. We checked the 7I77 and the serial interface runs OK down to about 3V on the 5V power
[16:05:00] <andypugh> The only problem is that halshow always displays unsigned ints in hex.
[16:05:12] <pcw_home> How is the 7I77 cabled to the PC?

[16:05:35] <andypugh> So my 8i20 max current is 0x000002EE
[16:06:02] <JT-Shop> Ok, I'll reseat the cables and try some more
[16:06:07] <pcw_home> Well you get god at reading Hex
[16:06:26] <andypugh> Yes, I am well awate that 2EE is 750 now :-)
[16:06:37] <pcw_home> Do you have a direct connection from th IEEE cable to the 7I77?
[16:06:58] <JT-Shop> yes
[16:07:21] <pcw_home> no extentions, flat cable etc?
[16:07:39] <JT-Shop> is was not sitting exactly correct on the 7i77
[16:09:14] <JT-Shop> I guess it would help to screw some mounting things into the 7i77 plug so the IEEE cable has something to fasten to
[16:10:18] <andypugh> JT-Shop: You could take the ones off the 5u25 :-)
[16:10:24] <pcw_home> doesn't cable have thumbscrews
[16:10:29] <pcw_home> ?
[16:10:47] <andypugh> (I just looked and the 5i25 has bail nuts, and the 7i76 doesn't)
[16:11:02] <JT-Shop> yes, but there is nothing on the connector for them to screw to
[16:11:15] <pcw_home> what?
[16:11:24] <andypugh> They both have threaded holes, but the thumbscrews don't reach
[16:12:07] <JT-Shop> like if you mounted it to a panel you screw the stand off looking things into the connector but they are not there
[16:12:26] <andypugh> On the 5i25 there are the little standoff-like mounting screws (for PCI plate mounting)
[16:12:28] <pcw_home> Oh missing jackposts
[16:12:44] <JT-Shop> yea, them things
[16:12:56] <Tom_itx> gee i bet a guy with a lathe could make a few
[16:13:06] <andypugh> I have a box full.
[16:13:09] <pcw_home> I'll make a note to production to install these
[16:13:11] <Tom_itx> me too
[16:13:13] <JT-Shop> been there done that :)
[16:13:37] * JT-Shop goes to take a couple off of an unwanted pc card
[16:13:58] <andypugh> So, that's JT sorted. Now my turn.
[16:14:00] <pcw_home> (quashing lame joke about jillposts)
[16:15:05] <andypugh> My RevD 8i20 shows a busundervolt error at 58.8V. The nvbusundervmax is 450 and nvbusundervmin is 350.
[16:15:10] <andypugh> Seems odd.
[16:16:20] <pcw_home> Does seem odd, is the voltage readout about right?
[16:16:58] <pcw_home> (comes from the same source)
[16:17:06] <andypugh> My multimeter says 59.2
[16:17:26] <pcw_home> ripple?
[16:17:35] <andypugh> 58.8 is the 8i20's opinion of the voltage
[16:18:06] <pcw_home> OK so thats good
[16:18:44] <pcw_home> It may in fact be a bug
[16:19:07] <pcw_home> I will check on Monday
[16:19:15] <andypugh> I am also a bit puzled that unplugging the enable connector doesn't set the no-enable fault pin
[16:20:56] <pcw_home> Thats sounds really broken
[16:20:58] <pcw_home> can you start without an external enable?
[16:21:48] <andypugh> With this board I can't start at all (no motor power, the green LED is happy)
[16:22:35] <pcw_home> red fault LED on?
[16:22:43] <andypugh> No
[16:23:17] <pcw_home> is the fault LED on with no external enable?
[16:23:25] <andypugh> No.
[16:23:38] <andypugh> Should it be?

[16:24:05] <andypugh> Let me switch to the other board and see what I get. (RevB, original firmware)
[16:25:11] <pcw_home> Yes. Its probably a bug introduced by the wait-for-vbus OK to start motor PWM patch
[16:25:13] <pcw_home> why 58V is not enough, I dont know though
[16:26:05] <pcw_home> it probably does not even look at the enable until VBUS is OK
[16:26:07] <pcw_home> We will fix this (if it has not already been fixed)
[16:31:20] <JT-Shop> got this again when running a test program http://imagebin.org/232652
[16:33:39] <andypugh> The older board behaves more as expected, though isn't setting the enable fault pin. However this might be related to mapping between my driver and the statis bits.

[16:38:48] <pcw_home> JT-Shop if its not a power or connection problem, it might be a ground loop so
[16:38:49] <pcw_home> sizeable HF ground current flowing between 7I77 and PC. You might try
[16:38:51] <pcw_home> grounding the 7I77s GND (5V gnd pin or spare encoder gnd pins) to frame ground
[16:40:43] <andypugh> I think I might be embarassed.
[16:41:00] <andypugh> One of the wires in my enable plug was the wrong side of the clamp.
[16:41:45] <pcw_home> Thats always a hazard with rising clamp connectors
[16:42:03] <andypugh> Unplugging the "enable" plug sets my "bus undervolt" flag..
[16:42:27] <pcw_home> Well that explains a few things
[16:42:39] <andypugh> I think I need the correct status bit mapping info.
[16:43:56] <andypugh> Which is the current manual version?
[16:44:23] <pcw_home> The 8I20 manual is fairly ancient and needs updating
[16:45:02] <pcw_home> but AFAIK the status bits have never changed
[16:45:58] <pcw_home> well REVD may have moved BUSLOWV from a fault to a status bit
[16:46:02] -!- FinboySlick [FinboySlick!~shark@squal.net] has joined #linuxcnc
[16:47:20] <pcw_home> Also JT-Shop make sure you dont have any encoder cable shields terminated at the 7I77 (sure fire way to get motor PWM noise coupled into the 7I77s gnd)
[16:49:26] <andypugh> I have a feeling that I have fault and status switched, looking at it.
[16:59:18] <JT-Shop> pcw_home: shields are only grounded to the frame on one end only
[16:59:55] <JT-Shop> I do see a small voltage when I measure between the 0vdc pin and ground on the 5vdc power supply

[19:04:48] <pcw_home> bits in interface reg 1?
[19:04:55] <andypugh> If I turn the power on then bit 3 goes off, and bit 9 goes high.

[19:05:13] <kirk_wallace> owhite: This link comes to mind: http://linuxcnc.org/docs/html/hal/halmodule.html
[19:06:37] <andypugh> If I unplug the enable plug then bit 9 goes low, and bit 8 goes high.
[19:08:24] <andypugh> Which, if it indicates anything, indicates that Faults are in the LSW, not the MSW? as bits 8 and 9 don't feature in the status register.

[19:18:01] <pcw_home> Ahh its a version change
[19:18:03] <pcw_home> buslowV and no enable moved from faults to status in rev D
[19:18:47] <pcw_home> noenablestatus_bit equ 0100h
[19:18:48] <pcw_home> pidonstatus_bit equ 0200h
[19:19:00] <pcw_home> buslovstatus_bit equ 08h
[19:19:52] <andypugh> I just went back to the old RevD and it does make more sense. (bit 24 when I turned the DC off)
[19:20:41] <pcw_home> (so the interface will start without these present but PWM.PID will wait until they are OK)
[19:20:47] <andypugh> And bit 17 for no-enable.
[19:21:15] <andypugh> So… How do we handle this?
[19:21:51] <andypugh> Different pinouts depending on software revision sounds bad.
[19:22:58] <pcw_home> you can or them together (the no enable and buslowv status were always 0 on revB)
[19:24:00] <andypugh> I don't think I can with the new structure. I _can_ create duplicate pins.
[19:24:13] <pcw_home> the no-enable and buslowv faults are always 0 on rev D
[19:24:53] <pcw_home> just or the bits together before any other processing
[19:24:53] <andypugh> Is it a firmware version thing or a revision thing?
[19:25:07] <pcw_home> its a firmware thing
[19:25:39] <andypugh> I don't have a way to do any logic on the pins, it's all a pseudo-PTOC now.
[19:26:57] <pcw_home> We really didnt have a choice since we changed BUSLOWV and ENABLE-IN to be status flags instead of faults
[19:27:53] <pcw_home> (to allow link startup without busv or perhaps interlocks open)
[19:29:01] <pcw_home> (current loop PID/PWM still wont start without these)
[19:29:12] <andypugh> I think it will be fine. we can just have fault.buslow and status.buslow pins. Only one will ever work on any particular board, but that seems fine
[19:30:12] <pcw_home> Yeah and eventually we will be able to update the firmware more easily
[19:30:13] <pcw_home> (no UART config needed anymore at least)

[19:33:38] <andypugh> This restructuring is all part of my idea of a way to change the firmware, and is all because I want to change my firmware :-)
[19:36:06] <pcw_home> You can do it VIA SSLBP with SSLBP V35 or > but its somewhat involved
[19:36:07] <pcw_home> (set remote device jumper to setup mode send lots or mystery commands to remote --> done)
[19:37:40] <pcw_home> I will update the 8I20 manual to reflect the REVD changes
[19:38:19] <andypugh> Is it rescuable if it goes wrong?
[19:38:47] <pcw_home> Yes as long as it does not write to the wrong place
[19:39:19] <pcw_home> then only rescue-able with a PIC programmer
[19:41:06] <pcw_home> basically there are 2 sets of code, the setup code and the run mode code
[19:41:07] <pcw_home> the processor always starts in the setup mode code than jumps to the run
[19:41:09] <pcw_home> mode code if the jumper is set for run
[19:41:39] <pcw_home> setup mode code is only rarely updated
[19:43:41] <andypugh> I will no doubt be asking for more details when the time comes.
[19:43:42] <pcw_home> so a firmware update utility need only write to the run mode area
[19:44:32] <jdh> there is a phone number and email address at teh bottom... He would happily discuss/explain anything needed.
[19:44:38] <jdh> <urk>
[19:47:46] <pcw_home> The problem now is that firmware update is not terribly complicated but our examples are because they are universal (hardware COM Serial port, hardware mesa serial port, OS serial port, SSLBP, PCI/mem/ EPP/ IO interface etc etc)
[19:50:39] <andypugh> I would only anticipate attempting to do it via SSLBP
[19:51:30] <pcw_home> Thats the only way that makes sense for LinuxCNC
[19:51:46] <andypugh> I would be looking at a command line sequence of loadrt hostmot / loadrt hm2_pci / loadrt sserial_flash firmware=path/to/firmware
[19:52:32] <andypugh> or loadrt sserial_flash 8i20.0.0.nvmaxcurrent = 30
[19:53:03] <andypugh> It's going to be a starnge sort of HAL component that always exits.
[19:55:27] <pcw_home> What about adding it to Michael Gs Mesaflash?
[19:56:53] <pcw_home> The latest does 7I80s as well as PCI cards (but not EPP however)
[19:59:16] <pcw_home> or rather than adding/ just use its code base as a way to get low level card access
[20:01:15] <pcw_home> We really need to have a firmware wrapper with the card name so you can't write 7I66 firmware to a 8I20 for example (or maybe just use the file name if you trust people not to change it)

[22:48:43] <andypugh> Just not as cheap as _we_ know it can be.

[22:59:29] <andypugh> pcw_home: My current version of the driver starts, srops. and restarts a RevD board perfectly.
[23:00:12] <andypugh> However it won't re-start a RevB board without me disconnecting the RJ45. Is this my fault or yours?

[23:39:05] <tjb1> I made it visible to the public
[23:51:08] <tjb1> Has anyone ever had a good experience at Fastenal?
[23:51:29] <r00t4rd3d> they have some sweet nuts.
[23:52:14] <r00t4rd3d> Ive never had a bad experience with them
[23:52:17] <pcw_home> andypugh Will 2.51 work?
[23:52:34] <andypugh> No, I did that test and 2.5.1 is just as bad.
[23:53:00] <andypugh> So I feel I can push my current patch then try to fix the problem in 2.5.1
[23:53:00] <tjb1> They wouldnt break a pack open for me

[23:55:32] <r00t4rd3d> you cant compare local shopping with internet shopping.
[23:55:41] <tjb1> Yes you can
[23:55:50] <andypugh> He just did :-)
[23:55:54] <tjb1> Fastenal wants to be a supplier
[23:57:12] <r00t4rd3d> if you dont understand why you can get stuff cheaper online then locally you need to lay off the plasma gas.
[23:57:29] <tjb1> Do you realize how many bolts I can get shipped to my house for $5?
[23:57:51] <L84Supper> way more than 10 I bet!
[23:58:30] <L84Supper> you mean including the cost of shipping?
[23:58:41] <tjb1> No, all my orders so
[23:58:51] <tjb1> All my orders so far havent been above $5 shipping
[23:59:03] <tjb1> Well…$5.60 or something
