This project gives you hardware, software and a pcb to interface CAN devices to your Linux PC.
The CAN200 Bus Interface for the PC Printer Port
The hardware consists of the
CAN controller
Philips
82C200 (or SJA1000) and the
CAN bus interface
Philips
82C250 or 82C251.
Very little glue components provide the port interface, which operates
with standard bidirectional PS/2 ports and Enhanced Parallel Ports EPP.

Added the Reset connection.
74HC132 instead of 74HC00.
The New Linux Driver
Jürgen Eder wrote a new driver for my hardware and the
Elektor
(a german electronic magazine) CAN hardware.
His driver works fine and has a lot of advantages over my old one.
Download the driver and some tools at
Jürgen's project page.
My Old (Obsolete) CAN200 Linux Driver for Linux 2.2.x
The driver for this interface is a loadable kernel module for Linux
version 2.2.x (tested under 2.2.14).
Care was taken to use it also on older kernel versions 2.0.x (not yet tested).
The CAN200 driver is released under the GPL.
Read the can200.lsm file and the
README file to get more informations about this driver.
Download the latest CAN200 driver sources.
Writing Linux Device Drivers (Kernel Version 2.4.x)
Linux Device Drivers, 2nd Edition, by Alessandro Rubini and Jonathan Corbet.
This book is for anyone who wants to support computer peripherals under the Linux operating system
or who wants to develop new hardware and run it under Linux.
Also available online.
Hardware changes from version 0.1 to version 0.2
