Martin Ling a09e9a20ed Overhaul timing in hackrf_transfer.
Rather than using sleep() for 1s at a time, set up an interval timer
that will fire once per second, and wait in the main loop for either
this or some other event.

On POSIX, the timing is set up with setitimer(), which generates a
SIGALRM signal each time the timer fires. The main loop runs pause() to
wait for any signal.

On Windows, the timing is set up using CreateWaitableTimer, which
provides an event handle that is set each time the timer fires. The main
loop runs WaitForMultipleObjects() to wait on this and an interrupt
event.

The TX and RX callbacks can now stop the main loop immediately when they
stop streaming. This fixes #1019.

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 default this will attempt to install an udev rule to /etc/udev/rules.d to provide the usb or plugdev group 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 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:

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
