Hi, I am wondering about the possibility (perhaps advisability) of using the multi_usrp object (in a custom C++ application with UHD) with an RFNoC FPGA image that includes a custom block. I realize that the multi_usrp object is only advertised to work with the default image, but that doesn't mean it can't be used with custom ones.
Specifically, I am interested in using the 'Replay' block. I would like to create my multi_usrp object as usual which will presumably create an RFNoC graph as follows: - transmit flow: Host -> RAM FIFO -> DUC -> Radio - receive flow: Radio -> DDC -> Host After multi_usrp object creation, I would like to re-wire the graph to replace the RAM FIFO with the Replay Block. This is desirable because it allows me to retain the bulk of my code that uses the multi_usrp object (with its handling of multiple devices and channel enumerations). I realize that I would still have some 'Replay' block specific code for populating the samples (recording) and then initiating the playback, but that should be relatively straightforward to implement. Let me know if this is a good or bad approach. If good, how would I go about re-wiring the graph? Thanks. Rob
