This lays the groundwork for implementing timed operations (#86). The M0 can be configured to automatically change modes when its byte count reaches a specific value. Checking the counter against the threshold and dispatching to the next mode is handled by a new `jump_next_mode` macro, which replaces the unconditional branches back to the start of the TX and RX loops. Making this change work requires some rearrangement of the code, such that the destinations of all conditional branch instructions are within reach. These branch instructions (`b[cond] label`) have a range of -256 to +254 bytes from the current program counter. For this reason, the TX shortfall handling is moved earlier in the file, and branches in the idle loop are restructured to use an unconditional branch to rx_start, which is furthest away. The additional code for switching modes adds 9 cycles to the normal RX path, and 10 to the TX path (the difference is because the dispatch in `jump_next_mode` is optimised for the longer RX path).
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:
- 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
