Hi,
Can I use usleep(1) or any other technique is there for GPIO .

Hi,
Thanks for answering.
Can you explain me clearly?
Thanks.
I'd suggest, at a minimum, looking at the MAN page for usleep().

Hi,
In USRP B205mini-i I am able to access the GPIO Pin. I have to
create a Pulse in the GPIO pin. I want to make high the gpio pin for
1microsecond and low for 999microseconds. How to achieve this
timings through coding. Can you give me the solution for this?
In coding after making high I am giving usleep(1) function but
when I am check in the oscilloscope it is showing 64microseconds.
How?
Because an application-land program executing on an ordinary
general-purpose operating system is unlikely to be able to
achieve repeatable, 1usec-scale timing. This has nothing to do,
per se, with UHD or USRPs, but rather, to understanding
how applications execute in a general-purpose operating system that
isn't ruthlessly optimized for "hard" real-time tasks.
