We built an FPGA version off of the radio_block, re-using the registers as:
SR_BASE = 160 SR_DB_GPIO = SR_BASE + 8’d32 = 192 SR_THRESHOLD = SR_BASE + 8'd40; ...etc RB_MISC_IO = RB_BASE + 0; RB_SPI = RB_BASE + 1; RB_LEDS = RB_BASE + 2; ..etc But now I'm having a real tough time finding the documentation on reading/writing these. Right now I have gotten to: auto usrp = uhd::device3::make(addr_string); uhd::rfnoc::block_id_t radio_ctrl_id(0, "Radio"); auto radio = usrp->get_block_ctrl<uhd::rfnoc::radio_ctrl>(radio_ctrl_id); and then I'm using: radio->user_reg_read64(addr); To read the registers -- Where addr == 24 to read the SB_DB_GPIO for example. But now I'm really struggling on how to write these values -- is this a two step write on the settings bus, and is there a better way to understand the mapping? (The real answer would be to fix the xml most likely, but I'm hoping to not go down that path quite yet.) Thanks.
