===== MDE8255LPT-1 Linux 8255 Driver Implimentation =====

Created by: [[people:travis|Travis Sidelinger]]

I reverse engineered the DLL provided with our MDE 8255 lab trainer and created a shared library for Linux.  This library is fully compatible with the original C header file.

==== Source Code: ====
  * [[projects:libmdedriver:mdedriverdll.h|mdedriverdll.h]]
  * [[projects:libmdedriver:mdedriverdll.c|mdedriverdll.c]]
  * [[projects:libmdedriver:Makefile|Makefile]]

Package: {{projects:libmdedriver-1.2.tar.gz|libmdedriver-1.2.tar.gz}}

==== Test Programs: ====
  * [[projects:libmdedriver:runner.c|runner.c]]
  * [[projects:libmdedriver:count.c|count.c]]
  * [[projects:libmdedriver:libieee1284-test.c|libieee1284-test.c]] FIXME
  * [[projects:libmdedriver:raw-write.c|raw-write.c]]
  * [[projects:libmdedriver:raw-read.c|raw-read.c]]

==== Todo: ====
  * mdedriverdll.c needs re-writen using the parport driver and libieee1284.so.  I am in progress, but currently stuck.
  * Create RPM package
  * More testing

==== Notes: ====
  * I was getting mixed results while reading from port A.  The chip suppling A seemed a little hot.  The results from A continuously fluxuated.
  * Root access is required until I can get the parport driver working.
