2 | * Filename: test_bms.c * |
||
3 | * Author: Marco Ziglioli (Doctor Stein) * |
||
4 | * Date: 27/06/2001 * |
||
5 | * 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. * |
