In this mode, FFT output bins from multiple hops are stitched together into a single set of bins per sweep. Each sweep is then processed with an inverse FFT to simulate a time domain signal at a sample rate equal to the sweep bandwidth. This wideband time domain signal is sent to the output as complex floats and can be piped to or viewed with tools such as fosphor or inspectrum. The output signal is discontinuous, so the time axis (e.g. in inspectrum) will be incorrect.
This repository contains host software (Linux/Windows) for HackRF, a project to produce a low cost, open source software radio platform.
##How to build the host software on Linux:
###Prerequisites for Linux (Debian/Ubuntu):
sudo apt-get install build-essential cmake libusb-1.0-0-dev pkg-config libfftw3-dev
###Build host software on Linux:
mkdir host/build
cd host/build
cmake ..
make
sudo make install
sudo ldconfig
By defualt this will attempt to install a udev rule to '/etc/udev/rules.dto provide the
usbor
plugdevgroup access to HackRF. If your setup requires the udev rule to be installed elsewhere you can modify the path with
-DUDEV_RULES_PATH=/path/to/udev`.
Note: The udev rule is not installed for by default for PyBOMBS installs as they do not ususally get installed with root privileges.
##Clean CMake temporary files/dirs:
cd host/build
rm -rf *
##How to build host software on Windows: ###Prerequisites for cygwin, mingw, or Visual Studio:
- cmake-2.8.12.1 or later from http://www.cmake.org/cmake/resources/software.html
- libusbx-1.0.18 or later from http://sourceforge.net/projects/libusbx/files/latest/download?source=files
- fftw-3.3.5 or later from http://www.fftw.org/install/windows.html
- Install Windows driver for HackRF hardware or use Zadig see http://sourceforge.net/projects/libwdi/files/zadig
- If you want to use Zadig select HackRF USB device and just install/replace it with WinUSB driver.
Note for Windows build: You shall always execute hackrf-tools from Windows command shell and not from Cygwin or Mingw shell because on Cygwin/Mingw Ctrl C is not managed correctly and especially for hackrf_transfer the Ctrl C(abort) will not stop correctly and will corrupt the file.
###For Cygwin:
mkdir host/build
cd host/build
cmake ../ -G "Unix Makefiles" -DCMAKE_LEGACY_CYGWIN_WIN32=1 -DLIBUSB_INCLUDE_DIR=/usr/local/include/libusb-1.0/
make
make install
###For MinGW:
mkdir host/build
cd host/build
cmake ../ -G "MSYS Makefiles" -DLIBUSB_INCLUDE_DIR=/usr/local/include/libusb-1.0/
make
make install
###For Visual Studio 2015 x64
Create library definition for MSVC to link to
C:\fftw-3.3.5-dll64> lib /machine:x64 /def:libfftw3f-3.def
c:\hackrf\host\build> cmake ../ -G "Visual Studio 14 2015 Win64" \
-DLIBUSB_INCLUDE_DIR=c:\libusb-1.0.21\libusb \
-DLIBUSB_LIBRARIES=c:\libusb-1.0.21\MS64\dll\lib\libusb-1.0.lib \
-DTHREADS_PTHREADS_INCLUDE_DIR=c:\pthreads-w32-2-9-1-release\Pre-built.2\include \
-DTHREADS_PTHREADS_WIN32_LIBRARY=c:\pthreads-w32-2-9-1-release\Pre-built.2\lib\x64\pthreadVC2.lib \
-DFFTW_INCLUDES=C:\fftw-3.3.5-dll64 \
-DFFTW_LIBRARIES=C:\fftw-3.3.5-dll64\libfftw3f-3.lib
Cmake will produce a solution file named HackRF.sln
and a series of
project files which can be built with msbuild as follows:
c:\hackrf\host\build> msbuild HackRF.sln
##How to build host the software on FreeBSD
You can use the binary package:
# pkg install hackrf
You can build and install from ports:
# cd /usr/ports/comms/hackrf
# make install
