flowgraph crashes when I enable a block
This flowgraph is based on the example in the PDU to Stream documentation. The difference is that now 'N' is now a formula instead of a constant ( int(samp_rate*tx_dur) ) As soon as I enable the one disabled block then gnuradio will crash with only a X window system error. And as far as I can tell this only happens when N is variable. VEC is defined as `pmt.init_f32vector( N, np.arange(N) )` [image: image.png] deleteme2.grc Description: Binary data
Re: flowgraph crashes when I enable a block
Just tested with a freesh build from main and it works. I can enable the block and run the generated flowgraph.

Time stamping data in a waterfall sink block
Hi all, For about the past week, I've been trying to figure out a way to timestamp data for when it's being replayed in the QT GUI waterfall sink block. I've been running into a few issues, first of which is even being able to extract the timestamp data from my capture, which is taken from a HackRF sweep and then converted into a cfile. The HackRF sweeps automatically come with timestamps for each data point which is how I know that they're actually associated, but I'm struggling to find a way to visually display them. I initially tried using a file meta source block but I was struggling to find much documentation on it and after poking around the QT GUI waterfall sink block's documentation for a while, it seems like there's no built-in way to change what the readout of the y-axis is. Could anyone provide guidance on how to extract the timestamp data from my capture and use it in a waterfall sink block on the y-axis instead of seconds, or how to modify the existing waterfall sink block? Thanks, Jason

I'm using v3.10.2.0 from source, in conda. I'll try with another version. On Wed, Jul 17, 2024 at 10:22 AM Volker Schroer wrote: > Just tested with a freesh build from main > and it works.
