pyhackrf-ctypes

pyhackrf-ctypes is a Python wrapper for libhackrf.
I create this project because I want a simple Python interface to my hackrf board. At First I use pyusb to directly get the data from HackRF, then I found pyusb can only move data at a rate of 5MiB/S, too slow for HackRF.So I choose to use ctypes .

Dependencies

  • libusb,NumPy

  • Python 2.7.x/3.3+

  • libhackrf

      sudo apt-get install python-dev,libusb-1.0-0 
    

Examples

import pylibhackrf ,ctypes

hackrf = pylibhackrf.HackRf()

if hackrf.is_open == False:
    hackrf.setup()
    hackrf.set_freq(100 * 1000 * 1000)
    hackrf.set_sample_rate(8 * 1000 * 1000)
    hackrf.set_amp_enable(False)
    hackrf.set_lna_gain(16)
    hackrf.set_vga_gain(20)    
    hackrf.set_baseband_filter_bandwidth(1 * 1000 * 1000)  

def callback_fun(hackrf_transfer):
    array_type = (ctypes.c_ubyte*length)
    values = ctypes.cast(hackrf_transfer.contents.buffer, ctypes.POINTER(array_type)).contents
    #iq data here
    iq = hackrf.packed_bytes_to_iq(values)    
    return 0

hackrf.start_rx_mode(callback_fun)

Todo

There are a few remaining functions in libhackrf haven't been wrapped.
