* 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 Co-authored-by: Martin Ling <martin-github@earth.li> * Fix documentation error in hackrf_biast.c --------- Co-authored-by: Martin Ling <martin-github@earth.li>
