* Filename: test_mes.c                                                       *

* Author: Marco Ziglioli (Doctor Stein)                                      *

* Date: 25/06/2001                                                           *

* Description: Test file for single period and pulsewidth measurement feature*
6
*              of PCI6025E timers/counters                                   *
7
*----------------------------------------------------------------------------*
8
* Notes: board is configured to provide a frequency of 1 MHZ through its FOUT*
9
*        pin (50). PFI3 (41) and PFI6 (45) are configured like source pins   *
10
*        counter 0 and counter 1. PFI4 (42) and PFI 5(44) are the gates for  *
11
*        the two counters. Please connect DIO7(32) to PFI4 and DIO6(30) to   *
12
*        PFI 5.                                                              *
13
*        With 'g' key a task is started which generate a square wave on DIO7 *
14
*        with a period of 2 secs. With 'h' key the same square wave is       *
15
*        generated on DIO6.                                                  *
16
*        When measurement is performed data are stored into Hardware Save    *
17
*        Registers: use key 's' to show this values                          *
