USRP BasicRX read_io() from pins

GNU Radio

Hi all,
I want to read an input from BasicRX pins using read_io()
I could not find a document how to do this in python.
An example would be great thank you in advance.

pins = u.read_io(0) # 0 -> side A; 1 -> side B

Thanks Eric,

Is there a pps input application/example done with this on USRP1
probably using a counter in python.
I would like it to count the pulses coming from a source and according
to
that
start collecting data.

I would appreciate if you could explain this a little bit.
Thank you

Do you think that it will work or
should I use verilog for this purpose?

Actually I did something in verilog but I guess when I stop collecting
data
some
of the data waiting in the buffers, so that is why I wanted to learn if
it
is easier to do in python.
Thank you

I did implement the pps input in the firmware
so I can precisely start collecting data and the buffer problem solved.
Thank you for your help

Not that I know of.
