CVS : $Id: test7.c,v 1.1 2004-06-01 11:42:46 giacomo Exp $
File: $File$
Revision: $Revision: 1.1 $
Last update: $Date: 2004-06-01 11:42:46 $
------------
this test shows a set of 5 tasks (+main+dummy+keyboard driver).
The first 4 tasks are scheduled by a EDFSTAR Module, whereas the
fifth one is a standard traditional EDF task. The 4 tasks uses a
budget of 10000/100000.
if edfstar.c is compiled with edfstar_printf3 active, a couple
(dline, curtime) is showed (in ms).
if cbsstar.c is compiled with cbsstar_printf3 active, the budget
replenishments are showed.
