pyparallel 0.2

Overview

This module encapsulates the access for the parallel port. It provides backends for Python running on Windows and Linux. Other platforms are possible too but not yet integrated.

This module is still under development. But it may be useful for developers. The Windows version needs a compiled extension and the giveio.sys driver for Windows NT/2k/XP. It uses ctypes to access functions in a prebuilt DLL.

It is released under a free software license, see LICENSE.txt for more details.

Installation

Extract files from the archive, open a shell/console in that directory and let Distutils do the rest:

Short introduction

>>> import parallel
>>> p = parallel.Parallel()  # open LPT1 or /dev/parport0
