Re: [Discuss-gnuradio] Asynchronous source with zeros in between

[Francisco Albani]

Thanks, Tim!

I tried to install gr-eventstream with the last GR version and had problems with cmake. I only had success after using the same cmake parameters I used building GR.

Nevertheless, I made a drop-in replacement of my block with ES Source and I was unable to mimic the previous behavior. Are you sure my block does the same?

Thanks and Bye!

You may want to look at gr-eventstream source block, this is exactly what it is intended to do, precisely timed if desired

Hi to all.

(this email subject may be inaccurate)

I need a block with the following characteristics:

* Input port for messages.

* Output port for complex/float/byte/etc. stream.

* Forecast always answers 0.

* Work function first check the message queue. If there are no messages, emits zeros; if there are, it emits the samples inside the message.

I'm willing to write it, but first I want to hear from the people in the list in case this can be crafted using existing blocks or if this idea is deemed to fail for some reason I can't see.

I need this in order to transmit N parallel burst radios using something like Polyphase Channel Synthesizer. The problem emerges when not all the transmitters have data to send and stop the other transmitters flows.

Many thanks!

Bye.
