gr-malahit is an linux oot-module for gnuradio to implement a malahit dsp source.
On linux it autodetects the correct soundcard from /proc/asound/cards.
This idea was taken from the osmosdr drivers.

To control the device the usb serial is used.

1. Dependencies:
    
   gnuradio (>= 3.9 ) with pybind
   alsa usb drivers activated

2. Installation:
    
   The build process is cmake based.
   So get the latest code from https://github.com/mihaly4/gr-malahit
   and change to the code directory. There
    
   $mkdir build
   $cd build
   $cmake -DCMAKE_INSTALL_PREFIX= "path to gnuradio installation" ../
   $make
   $su
   $make install
    
   After that executing grc you'll find in the section Malahit
    
   Malahit DSP
   Malahit DSP control

3. Usage
    
   Two modules are available:

• malahit_control
• malahit
   
  The control module only controls the sdr, while the other modules control the sdr and provide the IQ samples. All modules accept messages to control the frequency. That was the reason to introduce the control modules.  
  The malahit module was introduced, as gnuradio 3.8 does not contain gr-malahit at the moment.
