Subject: GPIO pin integration to osmosdr in gnuradio via argument
Message-ID: <596c75c8.bbb6500a.a11f7.b836@mx.google.com>

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

Subject: SDRSharp/Airspy on Debian
Message-ID: <CALFpvUHooryBdHhm+6FG9NF2yZUR1P=TKLyOG6wCzUew0VffbQ@mail.gmail.com>

Hi guys

I am attempting to install Airspy (before known as SDRSharp) on my Debian
9.0 and I am following this link:

https://rtlsdr.org/softwarelinux

When it gets to the line of Airspay Installation it quotes

"Don't forget to blacklist the kernel driver as mentioned here
<https://github.com/airspy/host/wiki/Troubleshooting%5Dhere%5D.%20%20*%20Download%20the%20latest%20zipfile%20copy%20of%20SDR#%20from%20[[http://airspy.com/download>
."

which links you to this wiki site

https://github.com/airspy/airspyone_host/wiki/Troubleshooting#linux-
debianubuntu

I was able to install airspy-git, gr-osmosdr, and gqrx but I get lost on
the part of blacklist the kernel >= 3.17

What can I do to blacklist the kernell driver?

Thanks
