Two Questions:
1) GRC comes with a slider but no command button (like the one with
usrp_probe). Is there an easy way to add one to GRC ?
Do I have to add one afterward using a python editor ??
2) Is there any way to implement a timer event with GRC ? I want
to step the "frequency" variable in USRP Source and the "baseband frequency"
variable in
FFT Sink at say two second intervals to simulate a scanner .
Or is there a better way to d number 2 ???
Bill
