For my final thesis I would like to design a reconfigurable antenna able
to work with the software radio device USRP-PKG.
In particular I would use the pins from IO_RX_05 to IO_RX_11 located at
connector J3 as I/O digital control signals in order to drive digital
switches in the daughterboard Rx/Tx XCVR2450.
I wrote at [email protected] for my issue. He answered “Yes, you can
definitely use some of the daughterboard GPIO’s for control of other
Which GPIOs are free depends on which daughterboard you are using and
the best place to control them would be to modify the daughterboard
code. The WBX might provide a nice example of controlling daughterboard
GPIOs because 6 pins are used for controlling an attenuator, so you have
If you are using the USRP drivers included with GNUradio, you can find
the WBX daughterboard code here:
If you are using the UHD software from Ettus R., you can find the
WBX driver source here:
The other daughterboard code is in the same directory.”
I have try to search the file, but it doesn’t exist. I have installer
GNUradio version 3.2.2 in ubuntu 9.04 with synaptic.
I don’t yet discover the GNUradio world, because if I cannot controller
my antenna I must change strategy, so I would understand if it is
Somebody can say me if I have to install some other package or if I can
it without change the daughterboard code?
I looked for the file but I couldn’t find it. I installed GNUradio
version 3.2.2 in ubuntu 10.04 with synaptic (the package is named
Before going inside the GNUradio world I would like to understand if I
can use it to handle my hardware.
Do you now if I missed to install some other packages or if it possible
to get the result without change the daughterboard code?
Thanks in advance
