[Discuss-gnuradio] a criticism to GNURadio's scheduler!

Hi, I worked on GNURadio for many hours. After all, I prepared my blocks in c++. However, the source by which I produce random bits (items with sizeof(char) ) doesn't work properly! By properly I mean, I wanted GNURadio to lead me control how it's going to call the *source.* It's crazily calling th

[Discuss-gnuradio] run a top block within a block!

Hi GNURadiores, I was thinking about how to change dynamically the blocks connected in my top block when it's running! After a long time, I reach to this point that I may have a top block is running within *a block*! (Also another top block runs* the block* itself. is that possible? If it is, I c

[Discuss-gnuradio] noutput_items

Hi, I'm confused about what is the return value of the work function if I have multiple output ports? I use *produce()* method to determine how many items produced on each port, so what does it mean to return again a number from work if I produced different number of items for each output port?? b

Hi, I want to ask these questions about how to write cmake lists when we making gr-xxx projects (modules) with gr_modtool: 1- How could I add dependencies of my project! For example I'm using a c++ library in one of my gr block, so how could I tell cmake to check the dependency? I read GNURadio t

Hello everybody, I want to connect a source to a sink block but there must be a sort of synchronization between them. The sink block should ask the source to generate data stream on some specific instances. Between these instances, the source block must put to the sleep or be disabled. How could I

It's better to say in this way: *how could I use stop(), start(), lock(), unlock() of the topblock methods? Is there any example of them?* Thanks, On Wed, May 14, 2014 at 1:20 PM, Martin Braun wrote: > On 13.05.2014 15:56, Mostafa Alizadeh wrote: > >> Thank you martin, >
