Re: [Discuss-gnuradio] UHD + BURX

[Josh Blum]

This information is good for anyone that requires custom daughterboard 
code for the UHD. Whether its a custom daughterboard, custom 
granddaughterboard, or misc modification....

Each file in uhd/host/lib/usrp/dboard is a self contained daughterboard 
implementation that inherits from rx_dboard, tx_dboard, or xcvr_dboard 
and registers itself into the factory system.

Each dboard object is given an interface that knows how to manipulate 
the io, clocks, etc... See 
http://www.ettus.com/uhd_docs/doxygen/html/classuhd_1_1usrp_1_1dboard__iface.html

So, one could easily build one of these dboard cpp files as a module 
outside of the uhd build tree. As long as the module is listed in the 
UHD_MODULE_PATH environment variable, it will be loaded at runtime, and 
things will work. Eventually, just install it into 
<prefix>/share/uhd/modules (when thats implemented...)
