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

/* 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
