Parallel port interface

[Jorge Godoy]

[I've posted this to the ttor mailing list as well. Sorry for whom receive
it twice.]

Hi!


We're doing a research project that involves controlling mini-windtrap
speeds and we're reading/writing data from the parallel port.

What I've found so far on a fast Google search for "python parallel port"
showed me some stuff that I'd have to interface with Python through SWIG.

If the program could be portable in Windows and Linux it would be a big
plus. We're thinking --- if it can't be written entirely in Python or with
modules that already have binaries for Windows --- in using a Linux only
approach (we, the programmers, use Linux only).


Any hints for modules I should take a look at?


TIA,

http://pyserial.sourceforge.net/pyparallel.html might work. Says
"This module is still under developement. But it may be useful for
developers."

You see... I must be blind or something like that

I was at the pyserial website but didn't see this.


Thanks!

Would ioport.py help? See:

Its Linux only atm, but it wouldn't be hard to port to Windows. I
might even do it myself!

you need to make a compiled extension with the inb and outb functions. i
have done that for pyparallel. thats the easy part, then you have to find a
driver that allows io port access on win NT/2k/XP. i used giveio.sys and
you'll find it on the page below too.
