What sort of device is it? There are a fair number of open-source
projects for jtag support, both as general support and for specific
micros, for example http://openwince.sourceforge.net/jtag/ .

Thanks, I'll look into it.
My Linux driver is in fact for JTAG programming.
I wonder what throughput you get when programming memory with a tool that
uses the giveio driver? Of course it would depend on length of JTAG chain
etc, but a rough idea of what's been achieved would be good to know.
Thanks again for info.
Regards,
Paul.

The normal way to handle this on windows is to use the readily-available
"giveio" driver, which allows normal applications direct access to
hardware. The application can the access the parallel port directly. A
convenient place to look for examples of this sort of thing is something
like the msp430 gcc project, or the ColdFire/683xx bdm gdb project, both
of which support a parallel-port based debugger tool (jtag or bdm), and
support both windows and linux. If you want to use a high level
language like python, the msp430 jtag project also has a python parallel
port module that should work nicely from either linux or windows.

You should probably repost your question over in
microsoft.public.developement.device.drivers
From the top of my head I would say you don't have to write a driver
at all. At least not because I know for sure that there are drives
around which let you bit bang the paralell port.

Hi,
I have a written a Linux driver to control a parallel port (bit bangs data
serially) and I want to port it to windows. The Linux device driver is
pretty simple, just a few ioctls and that's it. I have no experience with
windows driver development. Any help on any of the following, to get me
started, would be appreciated:
(1) I would like to find a simple skeleton driver that implements
ioctls - any recommended web sites, books etc?
(2) What tools do I need to compile the driver?
(3) What do I need to do to install it on a windows box?
Thanks,
Paul.
