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. -- Remove _rem_ before replying by email.

The Linux device driver is[snip] 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. HTH Markus

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. David

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. -- Remove _rem_ before replying by email.

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/ .
