From 6c49683490a4ba18b1cdf1ca1d98560684a63c71 Mon Sep 17 00:00:00 2001 From: adrian Date: Wed, 2 Jan 2013 04:02:27 +0000 Subject: Add a very skeletal spectral scan control application. The main use for this is to manually trigger spectral scan operations (athspectral -i athX start) whilst doing debugging. --- tools/tools/ath/Makefile | 2 +- tools/tools/ath/athspectral/Makefile | 16 ++ tools/tools/ath/athspectral/athspectral.c | 323 ++++++++++++++++++++++++++++++ 3 files changed, 340 insertions(+), 1 deletion(-) create mode 100644 tools/tools/ath/athspectral/Makefile create mode 100644 tools/tools/ath/athspectral/athspectral.c (limited to 'tools') diff --git a/tools/tools/ath/Makefile b/tools/tools/ath/Makefile index 0faadbf..c4c81ba 100644 --- a/tools/tools/ath/Makefile +++ b/tools/tools/ath/Makefile @@ -3,6 +3,6 @@ SUBDIR= arcode athdebug athdecode athkey athpoke athprom athrd athregs SUBDIR+= athstats ath_prom_read athradar athaggrstats SUBDIR+= ath_ee_v14_print ath_ee_v4k_print ath_ee_9287_print -SUBDIR+= athsurvey athratestats +SUBDIR+= athsurvey athratestats athspectral .include diff --git a/tools/tools/ath/athspectral/Makefile b/tools/tools/ath/athspectral/Makefile new file mode 100644 index 0000000..8aebde6 --- /dev/null +++ b/tools/tools/ath/athspectral/Makefile @@ -0,0 +1,16 @@ +# $FreeBSD$ + +PROG= athspectral + +.include <../Makefile.inc> + +SRCS= athspectral.c +SRCS+= opt_ah.h +CLEANFILES+= opt_ah.h + +opt_ah.h: + echo "#define AH_DEBUG 1" > opt_ah.h + echo "#define AH_DEBUG_COUNTRY 1" >> opt_ah.h + echo "#define AH_SUPPORT_AR5416 1" >> opt_ah.h + +.include diff --git a/tools/tools/ath/athspectral/athspectral.c b/tools/tools/ath/athspectral/athspectral.c new file mode 100644 index 0000000..8e6962a --- /dev/null +++ b/tools/tools/ath/athspectral/athspectral.c @@ -0,0 +1,323 @@ +/* + * Copyright (c) 2013 Adrian Chadd + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
