Hi all,
Is it possible to programmatically determine the "rfnoc_chdr_clk" rate
from a UHD application? More specifically, I have a custom RFNoC block
clocked from rfnoc_chdr_clk, and I’d like to programmatically
determine its clock rate from the associated custom software driver so
I can convert tick rate to physical units of time. I know it varies by
radio model [1], and I’d like the driver code to be portable across a
few models.
I’ve poked around quite a bit in the docs and code, and I haven’t
found an obvious solution in UHD 4. I guess I could dump it into a
register within my RFNoC block, but I wanted to make sure I’m not
missing something in the existing framework. Calling get_tick_rate()
on the block control object just returns 0.
Thanks!
David

Hmmm. The docs do suggest that "get_tick_rate()" on the *block* object
should work, since it exists in the block base class. I'm not an RFNOC
programmer, so just
guessing...
