 CVS :        $Id: test7.c,v 1.1.1.1 2004-05-24 17:54:51 giacomo Exp $

 File:        $File$

 Revision:    $Revision: 1.1.1.1 $

 Last update: $Date: 2004-05-24 17:54:51 $

 ------------

 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.
