Hello, For my applications the MAC layer of my waveform requires me to implement a few timers (e.g. for slot and frame times, etc).
What I'd like to do is exclusively use the USRP clock for these timers. I've tried mixing the system clock and the USRP clock before (see a few messages on this list from a few months ago) and I couldn't get the accuracy I needed. Is there any way to setup a callback using the USRP clock. Sort of like a UHD timed_command except instead of changing the gain, frequency, etc. I want to call some C++ function. Also, I think I could try to sync my PC clock with the USRP clock but it seems using "Unknown PPS" or "Don't Sync" are usually recommended but I don't understand why. Thanks, Devin
