* Date: 20/06/2001                                                           *

* Description: Test program for buffered gated event counting using PCI6025E *
6
*              board                                                         *
7
*----------------------------------------------------------------------------*
8
* Notes: FOUT are enabled to provide a frequency of 6250 Hz. You could       *
9
*        connect PFI3 (pin 41) and PFI6 (pin 45) to this source for counting *
10
*        edges. Gated counting are enabled and PFI4 (pin 42) is gate pin for *
11
*        counter 0 and PFI5 (pin 44) is gate pin for counter 0. DIO 7 and 6  *
12
*        are als configured to switch between 0 and 5 V. Connect DIO 7 to    *
13
*        gate 0 and DIO 6 to gate 1. Use 'g' (counter 0) and 'h' (counter 1) *
14
*        to change DIO lines value. On left area of the screen you should    *
15
*        see counter while counting and on the right area you should lock    *
16
*        counter values by pressing 's' key.                                 *
17
*        Notice that line parameters are enabled and accept inital value     *
18
*        for the two counters. If they aren't specified or they are wrong    *
19
*        counters start from 0x00FFFFFF (counter 0 which counts down) and    *
20
*        0x00000000 (counter 1 which counts up).                             *
