Re: [Discuss-gnuradio] USRP Transmit on Side B?

[George Nychis]

Hi Maxime,

This is a pretty difficult question for people to answer without your 
code for the C++ drivers yet.  But, since you've shared it with me... :)

On line 50 of USRP_Interface_tx.cpp, you're calling 
usrp_standard_tx::make() with nchannels set to 1.  This is the third 
parameter... try setting it to 2 and then using the appropriate mux.

I'm still trying to get the 2400 board working after I added my support 
to your code for it.

Eric and Jonathan, it would probably be very useful to re-use a lot of 
this code and pulling it in to the project for C++ daughterboard 
support.  It is far from following the GR coding conventions, but I 
could work with Maxime on fixing this up.  Maybe when he wants to 
release it when he's done with his project, we can go over the general 
structure and everything.
