k8055 for Mac OS X and Linux

Introduction

This software implements the complete(?) protocol to access velleman's K8055 card. This software was developped within the Universite de Technologie de Belfort-Montbeliard (utbm) (france) in the LO22 course (professor: Eric Bachard).

License : GPL

Developpers (v0.2) : Julien Etelain ( julien at pmad dot net ) and Edward Nys

David Downes provided fixes to make it correctly build on linux. Fixes are avaible in the 0.3 release. Thank's to him for this fixes.

Lastest version : 0.3 (utbm)

The base program

Requiments

GCC under linux, XCode under Mac OS X (http://www.apple.com/developer/)
libusb : http://libusb.sourceforge.net/

Compilation

Linux

gcc k8055.c -o k8055 -lusb

MacOS X ( you need to install the kext package first).

su
cp -r k8055.kext /System/Library/Extensions/k8055.kext
touch /System/Library

Then restart computer

./build_macosx

Syntax

The provided program offer some options, you can use the source to develop a software more adapted to your needs.

Syntax : k8055 [-P:(number)] [-D:(value)] [-A1:(value)] [-A2:(value)] [-NUM:(number) [-DELAY:(number)]] [-DBT1:(value)] [-BDT2:(value)] [-reset1] [-reset2] [-debug]

-P:(number) Set board number
-D:(value) Set digital output value (8 bits in decimal)
-A1:(value) Set analog output 1 value (0-255)
-A2:(value) Set analog output 2 value (0-255)
-NUM:(number) Set number of measures
-DELAY:(number) Set delay between two measure (in msec)
-DBT1:(value) Set debounce time for counter 1 (in msec)
-DBT2:(value) Set debounce time for counter 2 (in msec)
-reset1 Reset counter 1
-reset2 Reset counter 2
-debug Activate debug mode

Exemple : k8055 -P:1 -D:147 -A1:25 -A2:203

Output : (timestamp);(digital);(analog 1);(analog 2);(counter 1);(counter 2)
Note : timestamp is the number of msec when data is read since program start
Exemple : 499;0;128;230;9;8

499 : Measure done 499 msec after program start
16 : Digital input value is 10000 (I5=1, all other are 0)
128 : Analog 1 input value is 128
230 : Analog 2 input value is 230
9 : Counter 1 value is 9
8 : Counter 2 value is 8
