AW: AW: USRP, GPIO toggling and Gnuradio

[Dobler, Anton]

Is there any alternative to the standard GPIO UHD interface, that allows me the desired speed and is this issue I see related to gnuradio and its scheduler or rather to the UHD API for the GPIOs?​

BR,

Anton​

I am extracting the package rate of a receive signal using a rather complex GRC flowgraph, i.e. I am detecting the preamble of a receive signal and generate a clock from here. This clock signal period is within the range of 100us - 1ms.

Toggling GPIOs using the standard GPIO interface for signals this fast is likely not going to be very speedy.

The GR experts will have to answer your other questions.
