Hi Everyone, I am running custom FPGA firmware for a low latency control system on a USRP1. Presently I am using a variant of the usrper.cc tool for loading firmware and control of command registers in the FPGA. I need to be able to stream data over USB into a file or other application but this is not a straightforward addition to the usrper code since the implementation in usrp_basic_rx relies on the low level fusb code. I have attempted to subclass usrp_basic_rx to make use of usrp_basic::read(). This works fine except that when my program quits the usrp_basic destructors reset some FPGA registers intrupting operation of the device. What I really need is a program like usrper which can interact with the USRP1 interactively without reinitialization/deinitialization but with the ability to stream data over USB. Is there something like this in the gnuradio codebase that I am missing? It seems I have three options:
1. Reimplement the usrp_basic::read functionality withing usrper 2. Subclass usrp_basic rather than usrp_basic_rx and to avoid destructor behavior (still need to reimplement read()) 3. Try to do this with the UHD driver instead (I don't know if this will help at all) I appreciate any suggestions. -Mike _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
