* Author: Marco Ziglioli (Doctor Stein)                                      *

* Date: 27/06/2001                                                           *

* Description: Test program for buffered period and semiperiod measurement   *
6
*              capacity of National PCI6025E board                           *
7
*----------------------------------------------------------------------------*
8
* Notes: FOUT are enable and avaiable on pin 50 to provide 1 Mhz frequency   *
9
*        You should connect source 0 (PIN 41) and source 1 (pin 45) to this  *
10
*        freq source. Gate 0 (pin 42) and gate 1 (pin 44) must be connected  *
11
*        rispectivly to DIO7 (pin 32) and DIO6 (pin 30).                     *
12
*        Use 'g' button to activate gate_action_task which generate a square *
13
*        wave with a freq of 0.5 Hz and Duty cycle of 75%.                   *
14
*        's' button should show counters countent but gate_action_task       *
15
*        when active shows counters content automatically so 's' button isn't*
16
*        useful.                                                             *
