[Discuss-gnuradio] python/digital examples and UHD

Hi list,

over the weekend I spend some time trying to update the demos to work
with the UHD, I just started playing with git, so if you see something
stupid let me know ;-)

I put what I got on (in the uhd-examples branch):

address@hidden:mfischer/gnuradio-mfischer.git

However the part where it 'automagically' picks rx/tx bitrates is not
really working as I have no idea how to detect what device I'm talking
to. Also please note that as I don't have the right values for bitrates
and samples_per_symbol don't be surprised if the examples crash ;-)

The old generic_usrp.py had ranges for the possible decimation /
interpolation factors as we don't have this in UHD I'm a bit confused on
how to continue.

I started to add a function

samp_rate_range_t get_rx_samp_rate_range()

to UHDs single_usrp_sink / multi_usrp_sink which internally would ask
the corresponding _dev for the right ranges, depending on what device
you're talking to. I still have to figure out the ranges part though.

address@hidden:mfischer/uhd-mfischer.git

As I don't really have insight into the longtime plan for UHD,
I'm not sure whether that's the way to go though...

Can someone give me any hints whether this actually makes sense?

Happy hacking,

- -Moritz
