the xilinx one is free and *very* impressive
Altera also has a free version, but not with the NIOS processor core
* robin_sz nods
I have the Xilinx package as well (with MicroBlaze CPU) - just haven't gotten around to using it yet
its took me anly a couple of evenings from cold
fpgas are stunning technology
I had some wxperience with PLDs, PALS, CPLDs and the like, but the new chips are amazingly fast and *big*
didn't I see a 80c51 on an fpga that actually runs twice as quick as a proper 80C51
there are also PIC and AVR cores available
and PCI bus interfaces
[00:06:39] <SWPadnos> http://www.opencores.org
is a great place
* robin_sz nods
USB, ethernet, PCI, serial, couters, timers, video controller (!), etc
stepper motor controller ... :)
Steve hardy managed to write a stepper pulses to VGA adapter ...
with digital readouts
heh - via USB
fpga board, stepper pulses in one side, VGA monitor the other
and it plotted the path
hook that up to encoders instead, and you have an awesome DRO
I asked him if he used the open cores video driver ..
and he said .. "nah, it was trivial, easier to just do it" ...
NTSC (and PAL) video is pretty easy to generate these days - there was a project that used a PIC (only) to make a PONG game
and PICs suck
as long as you dont want colour
though the RGB interface of a VGA screen gives color pretty easily
(at least 8 colors0
see ya Jacky^
better go too.

Installing BDI 4.20 now, any way I can change the pinout for use with Xylotex before I continue?
read the wiki pages and recompile
or, make a hardware adapter.
I hate wiki's, just a glorified electronic post-it note
you're welcome for answering your question
cradek: That doesn't answer my question...
what doesn't answer what question?
Can I change it BEFORE/DURING the install
no, you have to install, then read the wiki pages, then use those instructions to recompile emc.
OR, make a hardware adapter.
So if I #define, then that's the ONLY thing I can use (driver wise)?
or does it ADD it?
it changes the pinout of the step/dir; the other stepping types are unaffected
so if U se a geck breakout board later on, would I need to recompile is what I'm asking?
also beware those instructions are for emc1.
alternately, you could use emc2, which lets you configure this using the hal files.
emc1 == bd1 4.20
bdi 4.20 comes with a bastard child of emc1 and emc2
isn't emc2 still beta
sure it is
but it has been able to drive steppers for a while now.
but hal isn't part of bdi 4.20 is it?
it's part of emc2, which you can build and run on bdi.
well bdi doesn't even like this machine, just chocked!
did you check your md5sum on the download?
doesn't like the video it seems.
when it gets to starting x server it chokes, unmounts everything and says safe to reboot.
that sounds not very helpful
XIO: Fatal IO error 104
is the error I get.
the real error is probably earlier
X server started sucessfully
XIO: Fatal IO error 104
there is another error after that one, but not beofre.
XIO: Fatal IO error 104 (Connection reset by peer) on X server "1:0 after 0 requests (o known processed) with 0 events remaining.
That is the whole error message, then another one after that in respect to mini-WM that's simular.
what kind of video card?
Intel CA810e mobo w/ onboard video.
try a real video card
it works under sid (fwiw)
might be totally different versions of X, I don't know.
I suspect sid is WAY older than bdi 420 though =)
paul always rants about how onboard video is bad for realtime
bbiab looking for another card. MAybe so, but it shouldn't choke the install.
I always disable onboard video and put in a real video card, just on principle. It's always served me well.

basic or custom install?
the custom doesn't let you make any consequential choices anyway
/boot doesn't need to be 100MB does it ?
kernels and initrd go there, so if you have several kernels, yes
but, not really.
I want to reserve empty space above 1024 for M$
03jmkasunich * 10emc2/src/hal/components/threads.c: fixed a typo that caused BDI-2.xx, -TNG, and -Live compiles to fail (strangely, BDI-4.20 compiled it without warnings..)
aw fuck... 'unhandeled exception' AND it won't let me save the crash dump to floppy!
Alright, this is getting old now... how many times do I have to reboot to get it to install 100% ?!
Jymmm: I've hed it never work on a P-II/LX440 board..
this is a celeron cpu on a intel ca810e mobo
now ext video (ATI AIW), but sound and lan are onboard plus a 3com nic
Kill the onboard sound in the bios..
it's SB128 chipset
Kill it and the davicom nic in the bios.
it's an intel nic onboard
ok, wtf ever, I'll give it a shot.
Jymmm: Make sure the 'agp apeture' is 2x the video ram..
pci video card
agp slot in the machine?
[04:35:20] <Jymmm> http://support.intel.com/support/motherboards/desktop/ca810e/sb/cs-012798.htm
sid doesn't have any problems with this mobo.
Phydbleep I'm just in a fowl mood over the whole thing ~ nothing personal if it comes across that way.
Jymmm: NP, Have you got the latest bios for it? :)
Jymmm: Only other thing I can think of is disable APM/ACPI, LPT, serial, sound, net and then use the onboard video set to use 8meg of ram with a 16 meg apeture.
power mgnt is disabled ~ I just seems that the installer just isn't liking this mobo too well.
my client is being an idiot.
he wants it one way... and I think it's stupid.
gah... I hate it when I don't get my way... which I can reason out to him.
he just wants it, cause it's the initials to his company.
so waht youre saying is your a real bitch when you dont get your way?
Ok, in case BDI fails install for a 3rd time, is there somethign else I can dl and install?
to the first q.
it's like, I see it, I see it won't work. I just want to waste my time.
cause 1, I know after I've made it, and I show them my design, they'll like it. But only after I show them their design being sucky.
if I do my design first, they'll be like, WTF we wanted our design.
and my design will be quashed regardless of how superior it'll be.
so, charge them double.... once for theirs, then again for yours.
that's what I'm gonna be doing.
but it's not even the money, though it will compensate me for my time.
I just hate doing work twice.
I hear ya. Just get a better quailty of clientel
i really shouldn't be complaining. They are paying clients.
Well, it seems to be installing now.... 40 minutes remaining
this may seem like a stupid question, but is anyone running servos with emc2?
we were last week
Jymmm: Mine wouls get that far and then bomb in the post-install. :\
good... just working on a new hal driver for the mesa 5i20 card
one of the simple configs is 4 encoders in, 4 pwm DACs out and 48 i/o pins
why not use a board with DAC's built in, if i may ask?
along with a few extras like index, dir and enables
well, I have this board and the pwm outputs and a dir bit work with the driver I have....
so.. the amp takes a digital input?
Phydbleep : Geeze, thanks! lol
the amp board has a lp filter and uses the avg dc value
mother fucker.... 25 minutes remaining and it craps out again...
(I think.... it has not been hooked up yet)
jymmm.. this machine doesn't sound reliable enough to run a router with
fenn It's fine with SID/2k
jymmm - boot an ubuntu disk and run the memtest86 overnight to see if it finds a bad memory
LawrenceG I ran memtest86 before installing for about 10 minutes - no problem.
"enter to retry" seems to have got it to continue installing (this time).
ok... maybe not long enough... you installs are blowing upafter 1/2 hour or so... could be heat related
cover is off, room is cold, temp is good, and this machien would run 24/7 no problem.
strange... enter to retry sounds like it could be a bad drive
either cd or HD
bedtime here... goodnight all...
I just burned this cdr (that's where it had issues)
jymmm is it a laptop?
Intel CA810e mobo
well, good luck.. if it were me, i'd feel around and see if any parts were hot
A-L-P-H-A whats the name/url of that utility you use thats like 'top'?
alex, wanna do a favor for me?
i need a logger on #emc-mazak, think you could set yours up to log both channels?
I think so
Jymmm: the famous retrofit ;)
no clue, sounds Jewish to me.... moz ill toff
mazak is a BIG machine manufacturer
google it up
still need to make a pretty html page for that
which one's fenn in those pics?
i dont think i'm in any of those, since i took all those pictures
roland will be compiling all of the pictures from the 150+ people who attended the fest
i'm sure i'm in some of them ;)
when's the fest over...
it ended on sunday at about 4 pm
roland locked all my stuff in the garage cause he thought i had left!
i was having dinner before i hit the road

anyone tried Opencascade Cad ?
Jacky^: looks cool, I looked at it a month ago but haven't tried it yet.
I think opencascade is more of a library set than a ready to go CAD system
Open CASCADE Technology can be best applied in development of numerical simulation software including CAD/CAM/CAE...

I am finally home from work :)
went to customer in this morning 05:00
I changed one value, in the PLC... that's user settable..
then I nudged another one, like 25ms..
and well, I went for a 300km drive.
fenn: looks really nice
03alex_joni * 10emc2/src/emc/motion/ (control.c mot_priv.h): fixed a small bug in the kinematics code, seems that all joints were tested for homing, even if the joints weren't active
it is ALIVE ;)
my toy is moving properly ;)
newbie asking: is it possible to run EMC on desktop machine?
without booting every time..
I tried to install rtai kernel on my machine and system hard locked when starting X
I also use JACK audio connection kit which needs some realtime priorities.. might cause problems?
I also need additional realtime-lsm module to run JACK
is it possible to try emc without any realtime support?

where is the fetch-me-a-brain command?
taking dogs, draining their blood and freezing them is an activity I approve of
bringing them back to life? nah.
but if you allow that, then some bonehead would come along and do it to *cats* too
euww. thats different
that would be inhumane
ridding the planet of dogs is simply garbage disposal
ValarQ, apt-get install intelligent-brain
thats wha we need ... an emc driven replacemetn brain.
emc1 or emc2?
well, the emc1 version works fine, but only installs in one version of human
and they can walk, but not run, and its all a bit jerky
the emc2 version installs more easily
but you need to leave them in college for twice the usual time to cinfigure all the options
and is much more configurable
the Mach2 equipped humans dont have either of those problems ...
but tend to fall over dead early in the lifecycle
got some good news today ...
looks like the parts I despatched for assessment have passed ...
should have an order soon <fingers crossed>
just the temperature
I'm thinking of continuing to clean the garage around the mill
(lots of aluminum chips around :) )
I think its cooler in there as well
(it's 29.1C in my office right now :( )
so - your machine is working - congratulations
yeah.. well ..
it's just a toy
ok - moving, not necessarily working :)
it's not supposed to work
movement is all I was earning for
well - congratulations on getting it moving correctly
will post some movies soon probably ;)

quiet in here
* Phydbleep is busily collecting Lexan and preparing for the excratory matter to impact the rotating air circulator..
hmmm no one home I guess
sort of here, but not here at the same time :)
I was just doing energy harvesting experiments today
sounds like you should live on Tatooine :)
got about 20 mW from an air whistle
what kind of whistle?
(kazoo or truck horn)
air nozzle blowing on about a 1x2 mm quarter wave acoustic stub
little organ pipe
very intense sound field
flow is supersonic
mach diamonds and all
I am a ways away from generating the electrical power needed...but i'll tell you what
loud, is it? :)
I can easily make an air powered ultrasonic cleaner!
about 100 acoustic watts
ouch - that'll split eardrums
It is enough to cause cavitation and cellular disruption for sure
but not dangerous to ears
fingers tingle when near it
like if you dip your hand in an ultrasonic cleaner
I don't do that too often ;)
but turning into electricity...what an impedance mismatch
air= 400 Rayls
piezo PZT= 3x10^7 Rayls
nedd q of 10,000 or so for stub match
what a unit the rayl is
10 pascal-seconds / meter
just volume velocity divided by pressure
wow. SI units!
can't make up your mind can you?? :)
SI except for the fact that a bar isn't SI (and a pascal is 0.1 bar)
anyway it is hard to tune stubs for that
10000 is a pretty high Q
may try piezopolymer instead
where's Bar? I see SWP_Away using pascal
low q. low impedance
I use C and assembler - haven't used Pascal for decades
aw, this stuff is a living I guess
have to generate 6 watts 100 kV with no (grossly) moving parts?
I would rather use an air turbine.
compressed air-> electrical power
client has asked for whistles and piezo.
nasty spl though...I think I am getting about 160 db SPL plus at one meter
that's a lot
diamond shock waves in supersonic flow does that
close in it is a big overpressure....compression waves are many atmospheres
so couple to piezo stack with quarter wave impedance matching stubs...get it?
uh - yeah - I got it. Well - gotta run now :)
(too hot to think about this kind of thing right now)
not in my office yet :(
86F in here
yep - gonna go out to the garage where it's cooler
(like only 82 or so)
