Detailed Description

A Parallel port driver using Linux ioperm/outb.

It is thread-safe, but can handle only 1 parallel port per instance. You need to instantiate this object in every thread where you want to access the port. If the threads write to different pins, they are guaranteed not to clear out each others data.

Constructor & Destructor Documentation

ParallelPort ( unsigned short int address = 0x378 )

Create a new Parallelport with a base address.

It can be used by the Orocos Thread system to output task scheduling block-sequences. You must try/catch this constructor.

Parameters:

address

The base address of the parallel port

Exceptions:

exception

if operation not allowed.
