Thanks Marcus, I have had a look at the GPIO example source. It contains some useful code, but I have not compiled and run it. Other example code in “Synchronising USRP Events using Timed Commands (17 April 2020)” has been used in the OOT block.
1) I have configured my B210(NI) EEPROM with the correct USB vid = 0x2500 and pid = 0x0814. The device is clearly identifiable and usable over USB3. 2). I have tried to identify the USRP using the following code prior to making an object:- uhd:: device_addr_t hint; hint[“serial”] = “3150322”; uhd:: device_addrs_t dev_addrs = uhd:: device::find(hint); 3). Or the following to create the object directly:- uhd::usrp::multi_usrp:: sptr device = uhd::usrp::multi_usrp::make(“vid=0x2500, pid=0x7814”); The codes are placed in the OOT constructor, compile and link with the appropriate headers. In both cases the flow-graph fails to run with the usual ‘block’ attribute error message. There are no USRP source or sink blocks in the flow-graph that could possibly conflict.

I am trying to exercise the GPIO bits on my B210 and to run other UHD member functions in a C++ OOT block. Can anyone provide me with a suitable make (object) statement for use with this transceiver. Many thanks, David Taylor You might look at the "gpio" example code that comes with the UHD source. -------------------------------------------------------------------------------- _______________________________________________ USRP-users mailing list USRP-users@lists.ettus.com http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com
