Hello Adrien, You can simply replace the UHD functions invoked by their Nutaq equivalent. This is very easy and straight forward.
There are two blogs on the subject, one for C language, one for GRC flow graphs. http://nutaq.com/en/blog/comparison-nutaq-api-and-usrp-hardware-driver http://nutaq.com/en/blog/how-port-existing-gnu-radio-waveform-picosdr-less-2-minutes I had a quick look to gr-air-modes-master, it doesn’t seem to have a .grc, so you will do the UHD->Nutaq replacements in the Python implementation (gr-air-modes-master\python\radio.py). The Nutaq API and FPGA cores come with in-depth documentation that explains each function (“doc” folder). But one quick way to get started is by comparing (using diff or Beyond Compare) the Pyton generated form a basic GRC example (eg: uhd_rx_dpsk.uhd.py from basic GR install) where you replace the UHD blocks with Nutaq blocks. The delta obtained is the list of UHD python function along with their Nutaq equivalent. In Radio.py (gr-air-modes-master), copy the UHD implementation starting at line 144 and paste it into a new “elsif” at line 177: elif options.source == "zeptosdr": #using Nutaq ZeptoSDR Then replace the “from gnuradio import uhd” and “uhd.usrp_source()” by their Nutaq equivalent: “import Nutaq” and “nutaq.rtdex_source()” respectively. Repeat with all the RTDEx and Radio420x configuration functions listed earlier with diff or Beyond Compare (set_center_freq , set_samp_rate, set_gain, etc…). Then, remake the proper connexions by replacing self.connect((self.uhd_usrp_source_0, 0), (…)) with self.connect((self.nutaq_rtdex_source_0, 0), (…)) Finally, do not hesitate to connect our tech support helpdesk if you run into problems understanding an API function when working on your code. http://nutaq.com/en/support Tristan -- View this message in context: http://gnuradio.4.n7.nabble.com/Modifying-gr-air-modes-to-work-with-Nutaq-s-Zepto-Pico-tp46634p46671.html Sent from the GnuRadio mailing list archive at Nabble.com. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
