Re: [Discuss-gnuradio] Getting the Count of FFTs

[Hasini Abeywickrama]

Hi Marcus,

It's like I need to start reading and processing the file after a certain number of FFTs are being written to the file. For that I would need to maintain a counter and I'm trying to figure out how to do it.

Regards,

Hasini

What would you need that counter for? There's the 1/(FFT length) fixed relation between samples processed and numbers of FFTs done, so this is pretty much a redundant piece of info, but maybe I'm just missing the use case.

Best regards,

Marcus

Hi all,

I have a GNU Radio flowgraph which uses a USRP to receive a signal, converts it to log power FFT and then writes the result to a file, using File Sink. I want to have a counter which increments with each FFT written to the file.

Is there a way of maintaining and increasing count of the FFTs written to the file, while the flowgraph is still running?
