Found another detail, in the above command line, or in the mills .ini file,
the uppercase -C is an error, with camview-emc a lowercase -c camviewcfg in
the 2nd EMBED statement, I am now getting everthing in the View CAM window
except the camera itself. If I click on the controls, I don't think all
the buttons are there now. On the right I have XOR, ON & SAVE, but no
machine controls. But I had not yet added the [HALUI] stanza to my ini
file, so now it appears to be all there except the camera itself with the
superimposed xyz dro (I have XYZA here but A is only plugged in as needed)

Obviously I could use some help there. But let me put my shoes back on & go
check to see if that 20 watt blue led on the camera is on. Yup, its on, so
the camera is streaming. But its not making it to either the lcnc screen
nor to the camview screen.
I have debugging turned up full in the .ini file, and the last output as it
brings up lcnc is:
campins.hal:10: Pin 'camview.hal_checkbutton1' does not exist
But I now have essentially the same complement of buttons as shown on the
.ru web page.
Running halshowconf, and selecting camview I actually have a
"camviewcfg.hal_checkbutton1" note spelling diff, I'll see if I can find
that.
In the meantime, have a good nights rest. I think its now the wee hour for
you.
