Daughter Board ID List

GNU Radio
1

Hello everyone,

I’m just diving into the GNU Radio/Python world and have been doing some
“Hello World” sort of exercises to become more familiar. Currently I’m
working on a python program to pole my USRP2 and return pertinent
daughter
board information. I am running GNU Radio 3.4.1 on Ubuntu 10.04.2 LTS.

My question is: is there a well defined list of daughter board IDs that
I
can reference? Currently I am using the information contained in
/usrp/host/lib/usrp_dbid.cc as my reference for the board IDs, but it
doesn’t match what the daughter board returns when I call
“my_usrp2.daughterboard_id()”. From what I have read on the mailing
list,
there are some inconsistencies with daughter board names (e.g. 0xffff
being
switched to “no daughter board” instead of “experimental”). Can anyone
shed
some light on this?

Thank you in advance,
Ryan

Could I suggest that, given that you’re just starting out, that you
start out with UHD, rather than
“classic”, for one, there are now daughtercards that aren’t supported
at all by “classic”, and that
will get “worse” over time, as more daughtercards are added, etc. All
new USRP driver-side
development and bug-fixing will happen on UHD.

Since you don’t have any “legacy” that you need to be backwards
compatible with, it’s a good point
to simply commit to UHD.

Thanks again,

Newer daughtercards aren’t supported in “classic”, and the WBX support
isn’t in Gnu Radio 3.2, for example. So if you must stick with
“classic”, get the latest version of it.

Thanks for your quick response Marcus! I neglected to mention that I am
trying to support research that inherits code requiring the “classic”
GNU
Radio system. I fully intend on using UHD expressly for the reasons you
specified once the PhD I’m working with has finished and moved on.

Since I’m only writing toy programs at the moment it’s not imperative
that
my daughter board probe be 100% functional: I’m only writing these to
gain
experience. But I was curious to know if there was a more specific list
of
daughter boards I may use. It sounds like I’m not getting the proper ID
due
to waning support of the “classic” system. Correct?

Thanks again,
Ryan
