[Discuss-gnuradio] Question about GNU radio working on other hardware devices

[Jacky Lin]

Hi there,

 

I have some questions about the firmware for other hardware device except USRP.

1.       I only found “gr-uhd” firmware for Ettus USRP from GNU radio source codes. I am curious how other hardware devices ex. HackRFs works with GNU Radio without official support firmware? For example, how to create HackRF’s own source and sink block while USRP has “gr-uhd” with its own source and sink blocks in it ?

2.       For GNU raido, I understand python is for GUI, data flow and graph and C++ is for algorithm implementation for each block. But I don’t understand how user’s input arguments or parameters are transmitted to hardware, what is the interaction between source, sink blocks and hardware module. What kind of interface that a hardware developer should provide?

 

If anyone could share some instructions or examples, I will appreciate a lot. Thanks in advance.
