microsecond pulse

[Technical_details]

Hi, 

I need to generate a TTL pulse output of 200KHz (period of 5 us) using a PCI DIO card. Also I need to recognize every falling edge of the pulse and count it from T0 to T21. Once reached T21 once again the count has to start from T0 and goes till T21 and continues. Is it possible by using LabVIEW program running on Windows OS to make the “DIO write line TRUE and FALSE continuously with a period of 5us” and also count every falling edge. Is it possible to achieve this by using a DIO card. Can anyone give suggestion.

Also i have attached the timing generation diagram required.

Padhu,

first of all, this question is better placed in the hardware forums. Nevertheless, if you get answers here, please do not double post in other forums.....

What device do you have? If the device does not support hardware clocking, you will never meet your requirements. If the device is correlated (hardware clocked), then there is at least a chance for success.
