Hi,
I have a couple high level questions here related with using GNURadio
with E310. I would really appreciate it if someone can give us a quick
feedback. Thanks.
1. Can we use E310 just like other non-embedded USRP platforms, with
which we run GNURadio models in a host computer and send I/Q samples
to E310 via an Ethernet connection?
There's a *VERY LOW BANDWIDTH* "network mode" that allows that type of
operation, but it was only ever intended for debugging purposes
and is not recommended. It really is intended to be used as an
embedded platform.
2. Are there gr-uhd blocks that expose the control of AD9361and
DDC/DUC in the FPGA, in which we can configure channel bandwidth,
filter settings, register settings, ADC/DAC sampling rate and sampling
rate change by DDC/DUC?
UHD in general, and gr-uhd in particular necessarily provide a very
generic API intended to allow (most) programs to be somewhat
hardware agnostic. So there are no exposed register-level API calls
for the AD9361, but you are free to "dive down" and expose those
things for your own application, all the time, not breaking anything
within the UHD API. Having said that, all of the things you want to do
are already handled within the UHD API as generic services--most code
never needs to "know" much about the underlying hardware, and
this is *PARTICULARLY TRUE* of Gnu Radio code. Personally, most of
my GR applications will run with many different types of SDR
hardware, including non-Ettus hardware, without changes other than
some command-line parameters to provide device-driver
guidance.

Arnold
