* Filename: test_mes.c *
* Author: Marco Ziglioli (Doctor Stein) *
* Date: 25/06/2001 *
* Description: Test file for single period and pulsewidth measurement feature*
* of PCI6025E timers/counters *
*----------------------------------------------------------------------------*
* Notes: board is configured to provide a frequency of 1 MHZ through its FOUT*
* pin (50). PFI3 (41) and PFI6 (45) are configured like source pins *
* counter 0 and counter 1. PFI4 (42) and PFI 5(44) are the gates for *
* the two counters. Please connect DIO7(32) to PFI4 and DIO6(30) to *
* PFI 5. *
* With 'g' key a task is started which generate a square wave on DIO7 *
* with a period of 2 secs. With 'h' key the same square wave is *
* generated on DIO6. *
* When measurement is performed data are stored into Hardware Save *
* Registers: use key 's' to show this values *
