qt waterfall sink time axis

2021-07-02 Thread John Murphy
Hey all, I have been flailing away, and failing, at getting the qt waterfall sink time axis to be scaled properly. Using gnuradio 3.8.2.0-3 on Manjaro One thing I found looking at the source code for the waterfall sink is that despite the option to set an update period the block always uses 10 se

If there is not enough data to feed the FFT at the selected display rate, the sink does appear to run slow and the time axis will not be accurate. Try either a smaller FFT, or lengthen the interval even more. On Fri, Jul 2, 2021 at 8:34 AM John Murphy wrote: > Hey all, > > I have been flailing a

Sorry - the smaller FFT would have no effect, so a larger update interval is the only solution I see. There are multiple issues in the github tracker that could be related. The gui sinks are known to need a little work and even rearchitecture. On Fri, Jul 2, 2021 at 8:47 AM Jeff Long wrote: > If

Happy 4th to everyone! I am doing a QA test and it goes into an infinite loop and there is nothing in my code to explain this, except my misunderstanding of writing code for Gnuradio. I am working with the general model because I have M input samples to every N output samples (M and N are not equ

Hello, I am working with Gnuradio 3.8. In response to my recent question, I think I found out why my program ran away in an infinite loop. It was because I was not consuming the inputs. So at the end of the loop in the general_work method when I used all the incoming data, I added the following l
