From: BSimon@randata.com.au (Brendan Simon) Subject: Device Drivers & cygwin32/mingw32 1 Feb 1998 17:13:56 -0800 Message-ID: Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: "'GNU-Win32'" I wish to do some data logging with an off the shelf counter/timer card. As far as I know there are no device drivers for Win95/NT available; just a library of functions for DOS using direct I/O access. As far as I'm aware, Win95 tries to be a protected operating system and doesn't allow direct I/O access from an application. Access must be via a device driver. I Linux can use direct I/O if you run as root. Is this possible with Cygwin32 or MinGW32 ?? I guess writing a driver is the way to go ( I need to rewrite the code to access the card anyway as the libraries supplied do not do what I want ). Can anybody give example code of I/O access in a driver format for Cygwin or MinGW. A simple skeleton program would more than suffice. ------------------------------------------------------------------------ ------------- A friend of mine is doing some graphing and data manipulation for the above data logging software. He is using Borland Delphi and I obviously wish to use one of the GNU packages. What is the best way to communicate between the two modules ?? Via DLL or device driver ?? Can a device driver be a DLL. Thanks for any help. Brendan Simon bsimon@randata.com.au or brendan@dgs.monash.edu.au PS.
