Hello, I’m trying to switch the state of the pin J2_3 of my xb100 through the argument line of the osmosdr block in gnuradio.
To do this, I added this code to the file bladerf_common.cc 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 /* Support of the XB100 to control pin J2_3 through the argument line*/ if ( dict.count("xb100") ) { if (bladerf_expansion_attach(_dev.get(), BLADERF_XB_100)) { std::cout << "Could not attach XB-100" << std::endl; } else { _xb_100_attached = true; std::cout << "Expension XB-100 attached" << std::endl; if ( bladerf_expansion_gpio_dir_masked_write(_dev.get(),BLADERF_XB100_PIN_J2_3, 1)) { std::cout<< "Could not set TRX pin direction" << std::endl; } std::cout << "J2_3 output direction selected" << std::endl; if ( dict["xb100"] == "TX" ) { if(bladerf_expansion_gpio_masked_write (_dev.get(),BLADERF_XB100_PIN_J2_3, BLADERF_XB100_PIN_J2_3)){ std::cout<< "sorry, but I cannot set pin to 1" << std::endl;} } else if(dict["xb100"] == "RX" ) { if(bladerf_expansion_gpio_masked_write (_dev.get(),BLADERF_XB100_PIN_J2_3, 0)){ std::cout<< "sorry, but I cannot set pin to 1" << std::endl;} } else { std::cout<< "Wrong parameter specified, should be TX or RX" << std::endl;} } } In my osmosdr bloc, I added this argument “ xb100=tx” but I don’t have my 5V on my pin :( I don’t understand why the pin is not setted when I start my flowgraph… Could you help me please? Thank you Samuel Verdon
