I do not recall, but from the file dates, I suspect I did.  I've checked 
both trees here without noting a src for that lib, so I have no clue what 
.deb supplied it.

I need to go get us a nose bag, back in a long hour.

Yeah, something like touch offs.

I am thinking your halio.c is duff, how long is it?

-rw-r--r-- 1 gene gene 12969 2013-08-21 02:49 halio.c
-rw-r--r-- 1 gene gene 13550 2013-11-21 18:12 halio.c-patched

And I am reasonably sure that I am using the patched version here.  In 
case you haven't found it, I'll attach it to a PM that just left.

I think camview should have been started by that 2nd ini file line.  Have 
you started it from a console to see if it complains?

2.5.4, updated just today Jon.

I'm back in the house, its set in for a rest of the night drizzle too, 
having hit a good quitting point of the Y screw for the mill, and am now 
awaiting the arrival of the ball thrust bearings from the far side of the

Apparently, this is a new file with 2.5, I had a 2.4

to 2.5 added this file.  Now, on to the next error message.

that is the userland hal library and produced during a normal build, nothing 
HAL-related runs without it

in RIP builds it should live in $EMC2_HOME/lib
in non-RIP builds it's either /usr/lib/ or maybe /usr/lib/linuxcnc these days

meaning - you need a working install of linuxCNC on that host to run camview-emc

liblinuxcnchal.so.0


Do I have to build camview-emc from source?

OK, found out at least part of the problem.  When it
tries to start camview-emc, it tried to use
liblinuxcnchal.so.0, which does not exist.  Anybody
know where it comes from?

I'm going to load all the dependencies for building
the software, that probably will fix it.

Thanks much, Gene!  OK, so apparently you also need to

Then, campins.hal has this line :

net forOnNet genescamviewcfg.hal_checkbutton1 => forOn.in forOff.in

I changed genescamviewcfg.hal_checkbutton1

which matches the description in togle-caa.ui, but it still

What version of LinuxCNC are you running?  I just did the
default update, and have 2.4.6 on it.

EMBED_TAB_NAME = CAM_View

If its dark & blue, check whats associated with the V4L2 video format spec,
it might not be correct for that camera.  Thats in the camviewcfg file.

My camera would be happier on a USB2.0 port, atom boards claim to have
only one USB2.0, but I've not found which one it is yet.  Currently
plugged into a USB1.1 port on the front panel & obviously suffering,
but it does work.  Just painfully slow.  My Shoe box is high on a shelf
and the control box sits beside it, so I need a ladder to get up to
it and play with ports vs camera cable.  I should look at the board
drawing that came with it perhaps?  :)

I now have 3 tabs in the backplot window, backplot, bare dro, and camview now.
The dro also shows in the camview tab, but needs a background text color set,
hard to read when its mixed into the camera video.

I hope this helps more than it confuses.

Cheers, Gene

OK, got camview-emc loaded, as described in the Wiki page
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Adding_Digital_Zoom_To_Camview-Emc

But, not all of it is working.  If I just have the line like 
this:

EMBED_TAB_COMMAND = ./camview-emc-f1oat.py -w {XID}

I get a video in the Camera tab, but if I
put either :
-C camview.cfg
or
-g cam.ui

in the line, then I just get a blank gray window for the Camera
tab.  Are there other files I need to bring in?

Also, the camview video is really dark and blue, is there an
adjustment for the color?

Thanks,

Re: [Emc-users] center finder camera / camview-emc

I'm going to update the howto docs shortly. 10.04 should work just fine 
with just adding the repos, installing the packages

http://psha.org.ru/debian/README.html

and making 2 lines of mods to your .INI

Add following lines to INI file:

  EMBED_TAB_NAME = Camera
  EMBED_TAB_COMMAND = camview-emc  -w {XID}


Camunits 12.04 also works except for the plugins. We still have to build a 
package for the plugins. Maybe sometime next week.

12.04 also lets you try the newer 3.4.55 RTAI kernel.

> What align stuff and align kit?

There is an alignment aid kit (google it) that works with camview-emc, 
fixes 2 problems.

1) it moves the machine from where ever it is, to put the camera looking 
at where the tool was before you moved it, and once you've located the 
target, then moves the machine back to match the target.  This you need to  
calibrate, normally by milling a teeny dimple, zeroing the machine, then 
doing the move, then find the target, at which point you can save this 
offset and use it every time.

The other is that if you have say a pcb to do both sides of, and it has 2 
or more registration holes at arbitrary locations, it can read those holes 
from side one, then turn it over and read those same holes in side 2 and 
apply including any rotation between front and back, and compensate for 
that.  It is not something I have exercised for real, not having made a 
board since I mounted the camera, but the theory says it should work.  
That would save me the work of making a custom pallet every time I have to 
deal with a new board size.

I do.

Its not too bad Jon, the main problem I had was running down a working 
copy of halio.c. so all the "align" stuff worked.  Seems there are 2 or 
more versions, but only one actually works.  OpenGL MUST work though, and 
finding the correct combo for that atom board wasn't exactly cut & dried.

The align kit gives a compensation for the off axis camera, which is on 
the right side of the spindle sled casting here, glued and bolted both.

Yes, I think that is the way I have a camera picture in another tab in Axis.
Sorry, I do not remember, how exactly did I set it up, but since I am not
really the guy to write the code and build from source, I think I simply
followed the instructions.
The part of "how to get it" mentions Lucid, even more, it says that plugin
for DRO  etc is not available for Hardy, so Lucid seems like a better
choice:

Re: [Emc-users] center finder camera / camview-emc

[Jon Elson]

OK, so the camera works.  Now, I'd like to
build a new LinuxCNC system, based on the 10.04 (Lucid)
kernel.  But, all the doc for camview-emc refers to Hardy.
Does anyone know if the various software pieces
(camview and camview-emc) that psha recommends
loading are available on 10.04?  Are there any gotchas
with this?  Does anybody else have camview-emc running
on a 10.04 kernel?

Thanks much in advance, the docs for this are a bit
hard to follow, and I'm afraid they may be out of date.

Jon
