pyhackrf-ctypes
|
||
|
|
==============
|
||
|
|
pyhackrf-ctypes is a Python wrapper for libhackrf.<br>
|
||
|
|
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.<br>
|
||
|
|
So finally i choose ctypes .

|
```python

import pylibhackrf ,ctypes
|
||
|
|
|
||
|
|
hackrf = pylibhackrf.HackRf()
|
||
|
|
|
||
|
|
if hackrf.is_open == False:
|
||
|
|
hackrf.setup()
|
||
|
|
hackrf.set_freq(hackrf_settings.centre_frequency)
|
||
|
|
hackrf.set_sample_rate(hackrf_settings.sample_rate)
|
||
|
|
hackrf.set_amp_enable(False)
|
||
|
|
hackrf.set_lna_gain(hackrf_settings.if_gain)
|
||
|
|
hackrf.set_vga_gain(hackrf_settings.bb_gain)
|
||
|
|
hackrf.set_baseband_filter_bandwidth(hackrf_settings.bb_bandwidth)
|
||
|
|
|
||
|
|
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)
|

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