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.
Instead of sending a signal to the process group, get our own process ID
and send the signal to it. This fixes a bug that prevented termination
when called from a script.
dBFS is defined in AES Standard AES17-1998, IEC 61606, and ITU-T Recs.
P.381 and P.382, such that the RMS value of a full-scale sine wave is
designated 0 dBFS.
A full scale sine wave on HackRF has the range -127 to 127.
We calculate the full scale ratio relative to a signal in which both I
and Q are held at 127. This represents a signal with sqrt(2) times
the amplitude, and thus twice the power, of a full scale sine wave.
Therefore to obtain dBfs by the above definition, we add 3dB.
The power measurement depends on the number of bytes that were valid
from the previous use of the transfer buffer.
The number of bytes to be read to fill the next transfer, is the full
size of the buffer.
Firmware now detects the hardware it is running on at startup and
refuses to run if it is compiled for the wrong platform. The board ID
returned by firmware to the host is now derived from run-time detection
rather than a compile-time value. A separate method to retrieve
compile-time supported platform is added.
On HackRF One, pin straps are checked to determine hardware revision.
This is informational to aid troubleshooting and does not affect any
function.
