That mysterious QuickCam
There hasn't been much traffic on this list. Is anyone besides Russell
I've not had time to do really thorough investigating, but here are a
few notes on the hardware itself:
The web page states that the PC version is probably just the Mac
version with a converter in the connector shell. Without actually
getting a Mac camera and ripping it apart to compare insides, this
seems very unlikely:
- The camera board says "WCAM100" on it, as does the board in the
connector; my bet is this stands for "Windows CAMera".
- There's no microphone in the Windows eyeball. There are some
unused pads where more components could be added, but not, I think,
- There's no intelligence in the eyeball. ISTR someone saying the
Mac version had a PIC in the eyeball. Not so with the Windows
version; all it has is the CCD and some power supply stuff and
I've traced most of the interesting-looking parts of the camera board,
guessing at the identity of the unmarked SMT devices. I'm working
on the board in the connector, though I'm not sure how much good
that would do without knowing how the PIC is programmed.
If anyone else is approaching this from the hardware side, speak
up, we can compare notes.
Has anyone tried running the driver software under, say, WINE? Does
that work? Can WINE (or any other emulator) be configured to trap
and log accesses to certain I/O ports? I'm not 100% familiar with
the '386+ protection mechanisms, but it seems this should be
possible in theory.
I have two goals here: one is to be able to use the quick-cam with
a good operating system on my Intel boxes; the other is to be able
to use it as a low-cost input device for robotic applications. Since
the 9-conductor cable between the connector and the eyeball seems
to be entirely digital, simply understanding that protocol would get
me half of what I'm looking for. Since I've worked out most of the
function of the eyeball circuitry, all I would need is
information on the CCD chip itself. It's an 8-pin DIP and presumably
has an onboard A/D since I haven't found any A/Ds elsewhere in the
camera. (The much-talked-about-on-the-net VVL1070 has 40-odd pins,
by contrast.) No visible markings, unfortunately (it's all window);
and I don't want to desolder it just on the off chance there's a part
number on the other side. Anyone have any ideas?
