Dear Luay Raouak,
greetings to DLR! I faced the same issue a while ago and since the Ettus guys said that an equivalent for rfnoc modtool will not be realized in the short term I invested a lot of time and helped myself by porting the Gain Block example/tutorial manually to 3.10.
I now have an OOT module with multiple RFNoC blocks for GR 3.10 and collected some useful "Developer hints" in it's README (how to create a module, add a new block, implement UHD bindings, implement GR bindings).
Or you could simply look at how I made the "gain block" and related bindings in this OOT and copy/adopt it to your needs.
It's available here: https://git.gsi.de/p.niedermayer/exciter/-/tree/main/rfnoc-beam_exciter
I have an X310, GR3.10 on Ubuntu 20 or 22 and UHD 4.4 (but I guess 4.6 should also work).
Generally, I found that using "|uhd.rfnoc_block_generic|" in combination with properties makes things a lot easier regarding bindings, since it means you need much less code and no custom Python bindings.
In my_rfnoc_gain.block.yml <https://git.gsi.de/p.niedermayer/exciter/-/blob/cf444ed055274ec826bc0956eed0b94debbab912/rfnoc-beam_exciter/grc/beam_exciter_rfnoc_gain.block.yml>:
templates:
imports:|-
from gnuradio import uhd
make:|-
uhd.rfnoc_block_generic(
self.rfnoc_graph,
uhd.device_addr(""),
"Gain",
-1, # device_select
-1, # instance_index
)
self.${id}.set_property('gain', ${constant})
callbacks:
-set_property('gain',${constant})
And in gain_block_control.cpp
<https://git.gsi.de/p.niedermayer/exciter/-/blob/cf444ed055274ec826bc0956eed0b94debbab912/rfnoc-beam_exciter/lib/gain_block_control.cpp>
|property_t<int> _prop_gain = property_t<int>(PROP_GAIN, DEFAULT_GAIN, {res_source_info::USER});|
void_register_props(){
register_property(&_prop_gain);
add_property_resolver({&_prop_gain}, {&_prop_gain}, [this](){
this->set_gain_value(this->_prop_gain.get());
});
} RFNOC_BLOCK_CONSTRUCTOR(gain_block_control){
_register_props();
}
voidset_gain_value(constintgain){
//The gain block fromthe tutorial only supports integer gain values
regs().poke32(REG_GAIN, (uint32_t)gain);
}
intget_gain_value(){
returnregs().peek32(REG_GAIN);
}
Regards
Philipp

Hello fellow usrp users,I would like to build custom RFNoC blocks for use with gnuradio 3.10 but I have not found any documentation on how to do it for this version. I know that for gnuradio 3.8 and lower gr-ettus was utilized to create the grc bindings necessary thanks to the RFNoC modtool but with the latter deprecated for gnuradio 3.9+ I find myself in a dead end. Has anyone managed to find a way to circumvent this issue? Any help would be very much appreciated._Setup:_ Platform: Ubuntu 20.04 Hardware: USRP X310 UHD version: 4.6 GNURadio version: 3.10 Best regards, _______________________________________________ USRP-users mailing list --usrp-users@lists.ettus.com To unsubscribe send an email tousrp-users-le...@lists.ettus.com
