3 * uC/OS-II

5 *
6 *
7 * ATmega103 Sample code
8 * File : TEST.C
9 * By : Ole Saether
10 *
11 * $Revision: 2 $
12 *
13 * Description :
14 *
15 * This file contains a simple example program showing how to use the AVR port of uC/OS-II. It is
16 * based on Example #1 from Jean Labrosse's book "MicroC/OS-II, The Real Time Kernel." The main
17 * difference is that this example does not display the time of day and the uC/OS-II version number.
18 * You must have the AVR UART connected to a VT102 compatible terminal (HyperTerminal in Windows is OK)
19 * to get the most out of this example.
20 *
21 * The support routines at the end of this file are included only to make this example run; they should
22 * not be used in production code without careful testing.
23 *
24 * $History: TEST.C $

26 * ***************** Version 2 *****************
27 * User: Ole Date: 8/13/00 Time: 15:14
28 * Updated in $/UCOS-II/AT-M103
29 * Added OS_TASK_DEF_STK_SIZE. Increase delay in Task from 3 to 10.
30 *
31 * ***************** Version 1 *****************
32 * User: Ole Date: 8/12/00 Time: 17:46
33 * Created in $/UCOS-II/AT-M103
34 * File copied from AVR port version 1.0 to the version control system.
