Using UHD control block

GNU Radio
1

Hi,
I install the GRAS. But I can’t find the UHD status block or UHD control
block in GRC. How can I use them? Is there any example about using UHD
control block?
Thanks in advance.

Hi Harry Z.,

UHD in general not related to GRAS.
I don’t know either a UHD control nor a status block. Are you referring
to the UHD USRP source/sink blocks?
However, if you’re trying to use any UHD related functionality, you will
need to compile GNURadio with
UHD support, therefore have the UHD headers somewhere Cmake will find
them (thus enabling gr-uhd).

If I got you wrong, don’t hesitate to say :slight_smile:

Greetings
Marcus

There is a control and status block in grextras. They should show up in
the UHD category tree when installed.

So I guess you need to check if the the cmake configuration for GRAS
found uhd support. The configuration verbose should tell us this. Just
post the verbose if you have any questions. THanks! -josh

Dear Josh,
I have checked the cmake output and gr_uhd is within the enabled
components. I’m using Ubuntu12.04 and boost 1.48.
