(Apologies for this repeat message; my original message didn’t seem to
appear on the mailing list archive.)
I’m writing a basic C++ UHD app to control some custom hardware on the
USRP2/N210; I’m using the multi_usrp class. I need the USRP2 to
continue sending out internally-generated data through the AD9777 DAC
even after my host app closes. Problem is, UHD seems to tell the
AD9777 to enter sleep mode at this point; is there any way to alter
this default behaviour short of modifying the UHD source?
A broader question is how to control the initial configuration of the
AD9510 and AD9777 when the host connects to the USRP2. I understand
this is a bit low-level for the spirit of UHD, but please let this
newbie know if there’s an elegant way to do this.
Another option would be disabling host-based modification of the
AD9510 and AD9777 settings entirely; I’ve modified the ZPU firmware to
configure them upon boot-up so I don’t really need it (though it may
be useful to keep).
Thanks in advance,
