PC_FFTW3f_FOUND indicates that FFTW3f was found via pkg-config.
It can also be found without pkg-config, if the necessary paths
are supplied. This fixes hackrf_sweep not being built in that case.
Refactor HackRF build system with a more modern CMake style.
Install files to allow library users using CMake to
find_project(HackRF CONFIG) and obtain HackRF::hackrf
and/or HackRF::hackrf_static library targets.
Add options ENABLE_STATIC_LIB and ENABLE_SHARED_LIB
to allow shared or static library to be disabled.
(Default builds both shared and static libraries.)
Add option ENABLE_HACKRF_SWEEP, when disabled allows
building without FFT library. (Default enabled.)
Add option DISABLE_USB_DEVICE_DISCOVERY for a compile definition
which could be used to alter libusb usage as needed on Android.
Counter-intuitively, this actually saves us two cycles because we unroll
the first iteration of the loop that spins on the interrupt flag, saving
a branch in the case that the flag is clear the first time.
* Add artifact publish step for Windows libraries and host tools.
* Replace runner.workspace with github.workspace.
* Update checkout task to v4 to supress warning.
* Update CMAKE for libhackrf and hackrf-tools to also install DLLs on WIN32 platforms.
* Update uploadartifact task to v4 since v3 uses an end-of-life node version 16.
* Add a new windows variable for the vcpkg cmake toolchain makefile.
Compiling with clang-cl, gives this error:
```c
hackrf-tools/src/hackrf_sweep.c(685,3): error: call to undeclared function '_setmode'; ISO C99 and later do not support implicit function
declarations [-Wimplicit-function-declaration]
685 | _setmode(_fileno(stdout), _O_BINARY);
| ^
```
fixed by simply adding `#include <io.h>`.
* Call fftw_execute once prior to starting IQ streaming
* Add options to use/save to an FFTW wisdom file and specify plan
* Fix bug where using -P would also enable one-shot mode
Fixes#1366Fixes#1260
Addresses #863
* Initial commit of hackrf_biast
* Cleaned up hackrf_biast
* Cleaned up usage info
* Include getopt.h for non-GNU systems
* Add support for overriding HackRF's default antenna power behavior in firmware. Add support for specifying antenna power behavior in libhackrf.
* Moved bias tee config routines into user_config.c, cleaned up operation of hackrf_biast
* hackrf_biast now calls usage() and exits when invoked with no arguments
* Fixed minor documentation error in usage()
* minor syntax cleanup
* Add some documentation to the host API call
* Add proper declaration magic in hackrf.h to hackrf_set_user_bias_t_opts() to appease Visual Studio
* Documentation changes suggested by @martinling
* Moved bias t setting above switch statement, removed line that explicit turned bias t off when entering OFF mode
* Change hackrf_set_user_bias_t_opts() to use a friendly struct() instead of a bitmask. User friendliness fixes to hackrf_biast options. More clang-format appeasement.
* Removed support for integer mode args from hackrf_biast
* clang-format error fixes
* Tweaked position of comment for clang-format v14
* Reformat files with clang-format v14 instead of 16
* Remove internal numeric modes for bias T settings

This avoids a confusing condition when hackrf_transfer is reading from
stdin with -R in which it does not repeat previous data but repeatedly
restarts reading new data after the user types Ctrl-D to indicate EOF.
The -R option should repeat previous data or should do nothing if the
input file cannot be rewound.
Fixes a bug introduced in 8a9af7a: Statistics skipped for initial
buffers not only when preloaded in TX mode but also in RX mode with no
preloading.
The total bytes transferred may appear inflated in RX mode when
receiving a small number of samples with -n, but the stats represent
data transferred over USB, some of which may have been discarded by the
host.
