This looks like a fun group.
Someone told me you guys might know how fast you can drive a parallel port in Linux
We are looking to use that for an advanced JTAG interface and don't have hard data as how fast the port can be driven. THX
around 25k pulses/second is probably the max for a non-heavily-customized kernel
if you use a custom bit-banging driver (like the i2c and now SPI) you can likely get faster
SWPadnos thx, what mode is best ?
for generating pulses manually, EPP I think
not ECP - the DMA features aren't a help
in fact, EPP may not even help -there wouldn't be any handshaking hardware on the other end
SWPadnos we have an FPGA on the other end
I think we'd want to drive it with DMA if we could
oh, in that case EPP or ECP would be better
It's parallel port -> Xilinx S3 -> JTAG pins
ok - the Spartan is meant as a JTAG interface to another board? (just making sure)
SWPadnos yeah it's gonna run TCLK at like 8MHz
I think the spec for ECP is 400kB/sec (I could be wrong though)
our scan chain is nearly 500 bits long
SWPadnos is that in bi-directional mode or one-way ?
one way, I think
in 16-bit mode ?
not sure about a 16-bit mode
Ok super. Thx for the help
IEEE1284 is only 8 bits wide
the interface chip may accept single writes of 32 bits, but it still sends the data out the port in 8-bit chunks
haha looks like you came to the right channel
[g2]: is this for recovering badly flashed slugs?
jtr_away you've got to work really hard to do that
nah - just unplug the cable while it's flashing ;)
SWPadnos that'll only trash the kernel and rootfs not Redboot
I suppose it depends on what you're flashing
The bootloader doesn't reflash itself
if you're using a serial (or network) updater, then yes, i't's harder
now you can just dd of=/dev/mtdblock0
or you used to be able to do 6 months a year ago
how many slug users are in here ?
oh - is a slug actually something (I thought it was a nickname for mis-flashed chips) :)
like coasters for CDROMs
mine is still stock - and for some reason I can't write to the drive (all of a sudden)
it's our pet name for the Linksys NSLU2 NAS device
ah, OK. I read about those recently
jtr_away I never did like (or use) the Linksys firmware :)
I've built my own devices now anyway
The "slug" I've always wanted :)
I got one a couple of days after reading about them running linux, backed up a few PCs to the drive, then got busy.
now it's on the todo list
you know we're running Debian on it right ?
didn't catch that, no.
There is BE distro, but DebianSlug is switching to LE to run the standard ARM Debian
recent returnee to linux - BE? LE?
so.. lemme get this straight.. you guys are running debian on a networked hard disk!?
fenn there a USB 2.0 device on there with a HD
BE (big endian) LE (Little endian)
last time I thought about that was mixing assembler with fortran
right - there was a recent SlashDot discussion on large networked storage
touch screen interface for controlling a DACS - the original multipoint video conference
this was one of the options that people liked (unless they had the misfortune of running the LinkSys firmware ;) )
if only one could store 6GB / second with it :(
I can do 2+ GB a minute through my AMD64 file server
that's only 180x too slow ;)
I shouldn't need that much at first, but I'd love to find something that can do it
2G/min isn't bad - what disks are you using?
6GB / second ?
* jtr_away wonders how swp is generating that much data
that's a single disk
If I striped I could to 3+
60x 5MP digital cameras, each can output 100MPixels/sec
actually, it's 9G, since the data is 12-bit
does the 60x count the burst mode of 6-9 a second ?
at first, it'll just be 7.5M x 60, stored as fast as possible
60 cameras, each running at whatever rate I can get them to run
(these are custom cameras I'm designing)
no - entertainment
think "The Matrix"
SWPadnos I'd think you could to that with an FPGA, and HDs
and a little power
basically, my SATA HD can drive nearly 60MBs
so it could handle 5 cameras with some spare
so a dozen setups gets you 60 camera
I need to be able to output video from one computer, so all the data has to go to one place
then an ethernet spec that allows timing to be sync to microseconds or nano seconds
I've been looking into GigE (or 10Ge) and infiniband for the transport
SWPadnos that's fine, put simple GigE on the back end and you can stream it out to be aggregated
GigE on each camera will almost allow the full pixel rate
that's not your problem
the problem is getting to/from disk
I'm still waiting on my customer to get me real specs anyway (what a PITA that is)
do you have devices for the steaming and storage ?
true. though I may only need to save a smaller region of interest from each frame, so the stored data may be significantly less than the captured data
not yet. any sugestions?
when would you need the devices to be ready ?
I think the project calls for a 6-month design cycle
that may be pushing it a bit though
I also need to find out what final output format is needed (both the physical media and the data format)
SWPadnos what's the probability of this project happening ?
99.7% or so ;)
I'm just missing the parameters, that's all
I've been thinking about building a Gigabit NAS boxes
that would be cool.
this would be a slight variation on that
I'm definitely interested in using the technology I develop for this in other areas
(which means, if we can develop something, I'm happy to have us produce and market it)
if you do it, and I buy the products, of course it's your deal :)
I was thinking the latter, but I'd imagine the former might work for the entertainment industry
well - we should talk about it offline. where can I contact you?
if you give me an email, I can send you contact info

hi anonimasu :)
anonimasu: working ?
I am buying yeah
looking for a new laptop
and a pcmcia paralell port card
but I found the card
so now it's laptop order time
anonimasu, are you the student? or was that aj?
A-L-P-H-A: no idea..
I am not a student though
anonimasu do you have a url for the pcmcia parallel card ?
[12:46:59] <anonimasu> http://www.quatech.com/
they'd allow me to return the card if it didnt work for me also
anonimasu: can't find laptops with parallel anymore?
jepler: oh, yeah byt they were heavy..
the one I got is < 2kg
yeah, I bet both of the laptops I have are >2kg
the normal one i have are about 4kg
they have parallel though
but it's a p4 inside ;)
radeon 9800 and stuff ;)
I know where to buy a desktop machine
thank you very much
I dont really care as I dont move too much mostly to lan parties sometimes..
but for work, I need to carry it around..
jepler: thank you.
does anybody have the url that cncuser gave about remastering his puppy cdrom?
[15:13:12] <rayh_> http://emc.sourceforge.net/cgi-bin/emcinfo.pl?Emc_Puppy
[15:14:18] <rayh_> http://emc.sourceforge.net/cgi-bin/emcinfo.pl?CncUser
First is Matt Shaver's stuff second is cncuser's.
going to walk a bit :P
I should call Matt and see if he has gotten the last two steps figured out.
Just got a usb stick and want to try booting from it.
wow, does that really work on modern computers now?
That is the question I want to answer for myself.
let us know!
Nope. That's not GPL info.<grin>
There's one of those self help books out.
something about stop walking on egg shells.
we "US'ers" have a saying "stop pussy footing around."
i think direct questions and direct answers work the best.
so as soon as I find out if I can boot from usb, I'll let everyone know.
I've got a full puppy iso. I should try that now.
be back later.
does anyone know what he was talking about?
direct questions etc
this is exactly the thing I was looking for: http://cooltool.he.fdread.org/cncforum/mastering/coolcnc-mastering-howto.txt
it's a script to remaster coolcnc, and it shows that he simply downloads the newest CVS source and builds it
there are the ADEOS settings etc
# for the pretty 3d look axis depends on opengl
and he thinks our software is ... pretty
jepler: the emc_1.0-38 sources seem to be on my mirror
alex_joni: are there any axis sources yet?
emc 1.0-38 source was on neutron too
and emc 1.0-38 is still incomplete/unbuildable afaik
jepler: it won't build the debian way, but I think it might build if you do it the normal way
cd src && ./configure && make
alex_joni: isn't that just our own tarball?
alex_joni: that may be true but it still doesn't fulfill the GPL requirements
SWP_Away is now known as SWPadnos
"plus the scripts used to cotrol compilation and installation of the executable" -- enough to rebuild the .deb package
is there an axis .deb?
SWPadnos: yes, paul_c distributes one on bdi up to 4.38.
yeah, diff says that's just our tarball, with none of the bdi changes
axis isn't listed in the package list. are you sure it's distributed as a .deb?
ah - I found it
it's marked as "earmarked for deletion from BDI-4.40
ii python2.3-axis 1.0+cvs.20050925 AXIS front-end for emc
[15:52:38] <SWPadnos> http://ourproject.org/moin/Package_list
this is the version on bdi4.30
its 1.1+cvs.20051221 on 4.38
yeah, apparently he's removing it after jeff's request that he comply with the license
SWPadnos: yeah, I saw that. I assume that's his way of getting back at me for asking him to comply with the license
or else an admission that he does not comply with the GPL
more likely that he doesn't give a shit if he has axis or not
is there a way to build a .deb that doesn't require the debian/ directory, and I'm just unaware of it?
not that I know of...
SWPadnos: he must have gone to some work to package it... that's usually not as easy as it first seems
I agree - I think he did do a lot of work, but that he's pissed off now, and doesn't think it's worth it to keep axis
ooh - I'm world famous on the Geckodrive list
good kind of world famous or bad kind?
good, but possibly embarrassing
I wrote software to download command sets to the G-Rex, and Mariss has oublished it for all to see
so it's good, but I don't really like the software much, so it's bad too
(quick hack != user-ready application)
this is weird. my vncviewer works fine to type into most apps (e.g., terminal, browser) but in qemu it is completely fubar
qemu running inside vnc
e.g., tab types "1", return types " " (at the puppy boot prompt)
I wonder if it's some odd keyamp thing
I've seen similar problems with vnc -> rdesktop
I still haven't understood why
anyone done a cnc conversion to the HF micro-mill?
(not the mini, the micro)
I'm thinking of getting one, there's a coupon to bring it down to really really cheap.
I wouldn't know where to get motors that small ;)
I guess you'd have to use pulleys to make the mounts fit.
is there a picture of this machine online?
[16:14:21] <SWPadnos> http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=47158
[16:14:26] <bill-xm> http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=47158
not much Y travel
I looked at the Homier version of this, and I couldn't bring myself to pay for it - it was too flimsy
what'd you get instead?
a used Bridgeport ;)
slightly different size
heh, a tiny bit bigger huh
I was looking at the minimill size though, so it's only 2.5x the weight
my main interest was in milling copper, so the machine has to be pretty stiff
hmm, ~$135 difference between the 'mini' and 'micro'
tell it to the judge
I mean - Hi Jymmm
SWPadnos: YOu're getting to be worse than me ! =)
at least I've got an extra 3 hours on you :)
or 3 hours wasted, depending on how you look at it
an extra 3 hours wasted
there ya go
so any further thoughts in the safe spindle control?
SWPadnos: YOU'VE HAD THREE EXTRA HOURS?! lol
but I'm only just drinking my first cup of coffee, so there
I'm gonna let you slide, cause I could take that to a whole other level
ok by me
anyway - I thought we had decided that the charge pump idea was enough for you, since you're not trying to prevent the software from turning the spindle on
only trying to prevent it from coming on if the software isn't running yet (ie, at bootup)
So it took your ass three hours to get to the coffee pot, do we need to get you one of those scooters- hoverround, things or just one of those pendants for the next time you have to say "I've fallen and I can't get up!" ?
I need an elevator
if you provide me with an antigravity flying harness, I'll be more productive
you dont need no damn elevator... an electric winch from Harbor Freight
oooooohhh - electricity
but you have to pedle the bicycle to power it
nah - I'll get my wife to do that - she likes exercise
(note that I said "likes", not "needs")
just for the record
it's been proved
you ever see that 50yo grandma for the bowflex commercial?
not that I recall
oh wait a second - she's in blue exercise gear?
[17:03:47] <Jymmm> http://www.fitgrandmother.com/
ok - yes, I've seen her
so, no you havent proved it
"for the record"
I never said my wife was 50+
and that's not her
but 10 years from now, I may wish it was ;)
we all do
"when I'm 64"
it always muses me that people byt exercise equipment
argh - need more coffee
but then they go out and get cars with remote controlled doors, leaf blowers, and the like
Yup. Puppy will install on and boot from USB stick.
of only we had a driver for the deskCNC board, I could show off at my friend's house ;)
There was a problem with the sk98lin ethernet driver with it so no net.
on this box.
that's a gigabit nic (or is it wireless)?
there's been some discussion on LKML recently about the skXXX drivers
The one on BDI works fine. (Hi Paul)
deskCNC isn't a driver, is it?
deskCNC is a software package, and a small microcontroller-based pulse generating board
it communicates over a serial port
I'm on the website now, but you still need geckos (or whatever), correct?
it's not a driver, just an I/O / pulse controller
When would you want to use this (serial) over parallel?
I wouldn't, since the software runs only on Windows
is there documentation on the serial protocol?
not that I know of
I have an older board, so I could reverse engineer it if necessary
but I don't think it's necessary :)
Jymmm: putting a lot of smarts on an external board means you can get away with no realtime code on the PC much more easily
YOu need a software driver for it?
you need their software for it
jepler: That I understand, I thought it was a PURE HW-ONLY device.
Kinda like TelnetIRC =)
so I think I'm gonna get that micro-mill. also a vise and an endmill holder, are there any other "must have" accessories?
harbor freight micro-mill
[17:25:27] <bill-xm> http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=47158
cheap, but so am I.
there's a %20 coupon too.
that thing costs as much as my motors (only because I got a really good deal on them)
maybe a clamp kit?
otherwise, each motor would have been 3x the price of the mill :)
what kind of stuff do you expect to machine?
oh yeah Jymmm, good idea
If I thought it would mill PCBs OK I'd probably buy one too
tiny stuff for model stirling engines and such, and maybe some engraving.
PCBs actaully need some of the tightest tolerances
I dont even have a drill-press now, so I need it to drill straight holes too.
you may be OK. unless you want to mill Inconel
very hard metal, often used in building small steam engines
we usually do 10/10 on cradek's maxnc, which it does without trouble
there's a cnc-conversion yahoogroup for that mill, and people have had good results.
inconel == Nickle Chromium alloy
I'm using soft stuff, brass & aluminum
jepler: only after lots of work to get zero backlash
cradek: yeah, luckily for me you did all that work
luckily, the work envelope is small, so you can keep relatively good tolerances
yeah, I dont expect to do any parts bigger than 2-3 inches across.
you'll probably need to replace the leadscrews if you want really good accuracy
yeah, if I cnc it later I'll upgrade some parts.
1/4-16 acmes are cheap
but that'd be a ways off, since I'm just a newbie.
note that the spindle power is 1/5 HP - that's significantly less than a cheap Sears drill press
it'll limit the metal removal rates
Cheap thompson ballscrews http://www.lowcostcncretrofits.com/Ballscrews%20and%20transmision.html
bill-xm you are aware that HF stuff is really loose tolerances/crap?
yeah, I know.
I have one of thier mini-lathes
bill-xm ok, cool.
I bought a trim router, turned it on and the outter case started melting.
I bought an angle grinder and it works awesome
with my hobbiest-sized budget it's pretty much that or nothing, so I'll make do.
bill-xm That's cool, just wanted to make sure you're aware of that is all.
yeah, I know it's pretty much bottom of the barrel stuff.
mostly I just want to get in cheap, I have a tendancy to pick up new hobbies and then get bored with something. so If i'm still interested in 2 years I'll get something better.
lol, fair enough
bill-xm do you live near a HF store by chance?
yeah, a few miles from here.
I was going to go at lunch.
is the retail website, a seperate entity from the online stuff
they are two different companys
they have different sales, but they're the same company
legally they are sperate
usuallly the retail stores will honor online prices if you bring in a printout.
at least my local store will
03swpadnos * 10emc2/src/hal/utils/halcmd.c: Added "%\n" prompt to script mode. Added fflush for piped use. Made "name" equivalent to "show all name", to improve script/piped use.
03swpadnos * 10emc2/docs/man/man1/halcmd.1:
I am plus one micro-mill.
when I think of mills, I think of the pain in the ass of transporting a ton of metal 350 miles, then the even worse part of getting it in the garage without heavy equipment
not "I think I'll go to the store and pick up a mill" ;)
yeah, thats the "micro" part.
makes it about the same weight as my rotary table :)
hey - wait. a 7-axis machine. hmmm.... :)
are you a machinist by profession?
SWPadnos: the most I ever played with is 18 ;)
nope - programmer / electrical engineer
ooooo - cool
SWPadnos: synchronized even
that's like, emc^2
well.. it was a big welding system
a few hundred k's
hi les_w :D
I may try your limoni stuff in the bottle
it is liqeur....not after shave right?
its lemon liquer
It looks like after shave
oh well I will drink it anyway
I think its sweet
lemon + sugar
It used a lot here around
I was very happy to get the package
I read the book
les_w: try it
les_w: seen how Pomepi was before the eruption ?
so now I know about capri,ischia, and procida
yes I liked that
capri is great, I loved it
especially Ana Capri
youre ready to came here now :P
welll I was in southern france/ monte carlo working
Id like to send a bigger bottle of Limoncello ..
I liked it
napoli looks even better
but I wasnt know about customs .. if its permitted :/
that's the way we should all live ;) just like Axel Munthe
I would like to live there part of the year
Jacky^: let him get addicted first :D
when the box came the seals were unbroken
was the flea still inside?
les_w: you like Pulcinella?
what is pulcinella?
its like a simbol here
wait .. k4ts is googling
I like my can of aria di napoli
if you look at the book and to thse photos ..
you can understand how Pompei is suggestive
how it was before..
it like to walk on the moon there
yes...some of the frescos and other art survived
originally very bright colors
many peoples there has been surprised by the eruption during they was doing sex ..
big mountain coming over you.. and what are they doing? typical
wonder how fast they have been surprised
no time to change position
Well I sure like the area...at least the parts I have been
Jacky^: sure they were like: darn, I need to finish this first
les_w: ih ih
les_w: I wouldn't mind a view like this: http://dsplabs.utt.ro/~juve/poze/italia/IM007656.JPG
I once looked at a 2000 yo roman villa for rent ...about the same price as a house here
not bad alex
les_w: that's in capri
Jacky^: but I need to say your blue grotto sux :)
[22:24:02] <Jacky^> http://www.virtualpompei.it/english/homepagee.htm
I do need to go to europe sonn. I like it.
the food is so much better
les_w: I agree :)
next holidays, came on :D
I f I keep making money....
les_w: I will came in georgia
several from europe have visited
paul comes each spring
yes that would be great
alex_joni: cool photos
I have a very nice guest room!
this evening k4ts was looking for a new camera to buy
ok guys, I'm off back to sleep
alex_joni: whats the latest camera you bought ?
was digital camera ?
[22:27:25] <alex_joni> http://dsplabs.cs.utt.ro/~juve/blog/index.cgi/photography
I bought a fuji
use itfor web stuff
jacky is my translator
we seen a Canon 5.1 mp this evening
about E . 340
the pixel count is not important
or a sony ..
Jacky^: make sure it's got good optics..
7.1 mp cybershot
very small camera
it can be 27MP for what I care, and it can still not be good
Yeah, I think the pixel count is a lot better tyhan the lenses can do on many cameras.
they are lens limited
all the average consumer cameras have mostly bad lenses
hi Lucio65 :)
ccd chips may geat inexpensive, but a quality lens will not
Jacky^: quite a few have Zeiss lenses..
:-) Jacky^ and alex_joni
the mine use Zeiss, its a sony
I have a zeiss microscope
k4ts: was using a 'normal' camera Minolta
look out for those, get a good zoom range (for personal use ok), and see that it's a fast lens (small F number)
she got a very nice photos with that
yeah my fuji has 6:1 mechanical zoom
les_w: I loved my HP850 (8x optical zoom)
I have 64 meg memory sticks for it
although my current 300mm lens is better :D
i have glasses Zeiss
les_w: CF or SD card ?
ok guys, I'm off
Lucio65: any specific questions, or just hanging around?
i have a old camera
alex_joni: lucio my friends
ahh.. ok, thought #emc related :P
but ...no ...ahahah glass !
* alex_joni goes to bet
G nite alex_joni :)
e friends of Jacky^
old nikon fe
I will go to the music room...I installed the new speaker drivers and amplifiers...the sound is good
got any pics ?
I will take some
I bought a whole carton of seas drivers from norway
les_w: now I can sing in your room!
to set up the equalization and gain I used mostly diana krall music
she sounds like you k4ts
les_w: ask to you son if his band is looking for a singer :P
ha...they play headbanger stuff
I played guitar in rock band too...long ago
noew my son does
but he is now getting back to college
les I love music of Diana krall
you sond like her!
hehe, k4ts tried to paly a drums some year ago
of course, she failed
k4ts should just sing...her voice is good.
but she sing very well :)
hi, im back from holidays
Hard to sing while playng drums!
les_w: Phil collins do that :>
yes phil could
my hi chris
cradek did you write the axis program
stupid work, stupid archiving, stupid tapes :(
Hi ray. I guess lake henry is frozen solid. Nice here....expect 65-70f tommorow
snowed a couple days ago though.
Quite a few oout on the water fishing now.
Might get to 20 tomorrow.
I grew up on the water in florida.
I like to fish
les_w <--- has webbed toes
need spikes for this water
take a look at the great cnc
How you doing.
hi rayh :)
lake michigan got a lot nicer looking...I guess it was the zebra mussels filtering the water. Very clear and clean
rayh: good, got a nice pizza this evening here
It is nice
weve been in 'pizzeria' :)
I'm on my way!
jacky and k4ts always make me hungry.
les_w: You were in Milwaukee?
oh...I have the limoni pasta and sausage they sent
les_w: thats is cool
I have beento milwaukee a good bit
but I lived in evanston
* rayh goes and digs something out of the 'fridge. brb
there are hundreds of things lik the carpentier you seen here around
very nice :)
rayh is now known as rayh_away
haha you made ray hungry
when ray says they are on the lake fishing....
It is ice fishing
nice, I love to fish
They cut a hole in the ice
but i usually go on the beach at the sea
and put up a small building over it
as soon as you catch the fish...they freeze
at least they remain fresh
they fish for trout, salmon, and others
I fished for sardines in nice
in a lake ?
ih ih les_w
I like to fish in lake, but I prefer to eat fish from sea only
you know in nice the people speak italian...not french
I dont like trouts, or similar :(
I like fish from the sea better also
itmay depend on how theyre cookied
les_w: I speack italian good?
you speack very bad
bad then me :(
k4ts: i don't know....I could not even figure out whether the bottle you sent was after shave or liquer
is after shave
it was so hot last night i got no sleep
Jacky^: is bad
i'm going to drink it anyway.
summer there chris?
down under. I wish it was hot here.
well, turn on the ac at night
damn lag and wifi :(
les_w: you should drink the lemon liquer at 3-4 C�
ok I will cool it to 3.5c
dont have one
k4ts: says it should go in a freezer before
chris, the japanese or chinese ac are selling for us$90 for 5000 btu
is there some similar liquer there ?
k4ts: ok. I will put it in the freezer
no, i haver never seen similar here
ok, if you like it we will send some bigger bottle :P
you promise it is not after shave?
looks like cologne bottle!
yes is cologne for to shave
oh...the sausage...should I cook or not?
here's the recipe
do not cook the sausage
just cut and remove the skin from the sausage
I am now too hungry. I will go eat like ray. Later!
its a bit
but not impossible :)
I can remove the skin
after i get 200 more scratch tapes
