[Discuss-gnuradio] [USRP] tracking the transmission/receiving process

[Logan Wu]

Hello,

I've been tracking the source code to figure out the procedure of
transmission/receiving. All I've found out is that the parameters (e.g.
freq, gain, etc.) are stored in a property tree, and messages are
inserted to the tail of queue. But how does the transmitter/receiver
(daughter board) know when to transmit/receive? Specifically, which file
in UHD host code does the job of notifying the hardware to
transmit/receive?

Thank you,
Logan
