Re: Porting Windows Driver to Windows CE

OK. There is only one camera driver in source form that I can think of, but
it seems to be very well-documented, if targeted at CE5, not 6, which
complicates things because of the change in kernel architecture from CE5 to
6.

If your actual target is CE6, you'll need to read up in the CE6 help on
porting drivers. I think that there's a CE6 version of the driver in that
evaluation edition (remember to install the source), so maybe that will be
all that you need.

1) It depends on what sort of driver we're talking about. There's no WDM
in
Windows CE, so, if you're using that on the desktop, you'll have to
either
build a wrapper for Windows CE calls that satisfies the existing driver
code's need for WDM.

2) You can download the evaluation edition of Windows CE 6.0 from
www.microsoft.com/downloads. No, there's no separate DDK. Having one
wouldn't really make sense, since some devices might have, say, USB
support,
and others might not. Some might have Bluetooth and others not. Unlike
on
the desktop, where every box basically has the same OS in it, that's not
the
case with Windows CE, where the list of OS features in a given device is
*entirely* under the control of the device OEM.

What sort of driver are we talking about?

Hi:

I was asked to investigate the effort of porting existing Window XP
driver
to Windows CE. I did some basic reading and am in process of installing
an
evaluation version of CE6.0 on my computer(the download process seems
to
be
very slow).

I have some basic quetions regarding the task.

(1) My current impression is that CE driver uses a complete different
set
of
kernel APIs from the Windows Kernel API explained in Windows DDK. Is it
true?

(2) There is no CE DDK similar to the windows DDK. If true, what is the
availabe documentation from Microsoft that explains all the Kernel API
and
CE
driver development?

Thank you very much,

cheers,
