Package information =================== This is a pair of hopefully useful control programs for Video for Linux 2 (V4L2) radio card drivers. The focus is on control, so you may find these programs a bit unfriendly. Users are encouraged to investigate the source and create wrappers or new programs based on this design. fm - a simple tuner fmscan - a simple band scanner fm == This is a simple program that will send commands to your V4L2 radio cards. It was written mostly so I could have something to send commands at the drivers being created or debugged here. The usual mode of operation is to tell the radio to come on to a given freqency. In these examples, 94.3 will be used since that's a station that happens to get tuned here frequently. To turn the radio on to that frequency at the default volume, you'd do "fm 94.3" and call it done. If you wanted to crank it up to full volume, another argument would be needed and the command becomes "fm 94.3 100". Volumes range from 0 (off) to 100 (full intensity). There is a -q option that will suppress messages about tuning, volume changes, and so forth. Keeping your tuner quiet may not seem like such a useful thing at first, but it can be very handy inside an IRC script. Having a program scribble on your channel window when you do /KILO or similar is not enjoyable. Besides direct tuning, there are also "on" and "off" commands. They will turn the card on and off (mute) as you may have guessed. Finally, there is volume control. To go up a notch, use +. To go down a notch, use -. Simple. fm configuration ---------------- You can create a file called .fmrc in your home directory that contains values for the default volume and default volume stepping. This way, you can have your radio card always come on at a certain volume when you don't explicitly list it on the command line. The volume stepping controls how much the volume changes during a - or + operation. This file is not required for operation of the program, and it will not even give so much as a peep if it doesn't find it. The defaults are used when you don't specify values. The values are 12.5% for default volume and 10% for default volume stepping. Here's what a real .fmrc might look like ... VOL 50 INCR 10 Here we say the default volume is 50%. Then we say the increment value for volume changes with + and - is 10%. These values were obtained by playing around with the numbers until things behaved the way I wanted. Be aware that some cards only have a couple of volume steps, so you may not notice a change right away. The Cadet hardware, for example, has two settings: off and *VERY LOUD*. Any volume setting will turn it on. The Aztech card has 4 settings (off, low, medium, high) and you'll notice it change when you cross the boundaries. The Aimslab RadioReveal card is actually based on analog volume control, with 10 steps emulated within that range. There are some other options available: -d - select device. If you have more than one V4L2 radio card in your system for some reason, use -d to select the right one. This is probably only useful if you like writing drivers for these things. -o - override card frequency range - Some radio card drivers don't actively enforce the frequencies that you can tune to. Use this switch and fm will send any frequency you want to the driver. This alone will not make an unmodified card receive frequencies from outside the design range. You have to change the tuner hardware in order to enjoy such broadcasts. -t - select tuner - Certain cards have multiple tuners - usually used for different bands. The ADS Cadet driver is known to support this, specifically using 0 for FM and 1 for AM. To tune AM frequencies, remember that fm expects MHz style input, and do the following: For 1200 kHz, enter 'fm -t 1 1.2', since 1.2 MHz == 1200 kHz. Yes, tuning am frequencies with 'fm' seems backwards, but that's life. Crafty hackers may want to add some code to make the program check argv[0] and behave differently. fmscan ====== This simple little program will command your radio card through the radio band and show which ones have a accumulated signal strength of 50% or higher. This process can take awhile, and can vary greatly depending on the radio card in use. By default, the range scanned is 87.9-107.9 MHz in .2 MHz steps, since that's the standard band here in the USA. Users in other regions should set the appropriate information for best results. V4L2 /dev entries ================ By default, these programs use /dev/radio0 to access the hardware. This can be changed with -d if you have more than one. If you have been using v4l radio cards for awhile, you may already have a /dev/radio. That is now "legacy", and should be symlinked to /dev/radio0. To create the proper device entry, either do "make devices" as root, or create it by hand with mknod (c 81 64). The proper device listing looks something like this in 'ls -la' ... lrwxrwxrwx 1 root root 11 Jan 20 03:19 /dev/radio -> /dev/radio0 crw-r--r-- 1 root root 81, 64 Jan 20 03:19 /dev/radio0 Other cards follow the same pattern - radio1 would be (81, 65), and so on. The owner and permission data should be set to values that agree with your system's personality. If it's mostly a solitary system with few or no users, the above settings will be fine. However, if you have other people running around on your system, consider making the device part of a "radio" group or maybe even "console" if you use such a thing. That will keep random individuals from doing odd things to your radio like changing it to a classical station while you're listening to some death metal (or vice versa).

Having to rename by hand is ugly. ## (We might end up doing this anyway to support other compilers.) ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like ## -MM, not -M (despite what the docs say). ## - Using -M directly means running the compiler twice (even worse ## than renaming). if test -z "$gccflag"; then gccflag=-MD, fi "$@" -Wp,"$gccflag$tmpdepfile" stat=$? if test $stat -eq 0; then : else rm -f "$tmpdepfile" exit $stat fi rm -f "$depfile" echo "$object : \\" > "$depfile" alpha=ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz ## The second -e expression handles DOS-style file names with drive letters. sed -e 's/^[^:]*: / /' \ -e 's/^['$alpha']:\/[^:]*: / /' < "$tmpdepfile" >> "$depfile" ## This next piece of magic avoids the "deleted header file" problem. ## The problem is that when a header file which appears in a .P file ## is deleted, the dependency causes make to die (because there is ## typically no way to rebuild the header).

It should now be better at accurately finding radio stations. - Add Autotest test suite and, in the process, convert the packaging to use Autoconf and Automake. - Some code and some documentation used a range of 0-65535 for volume, other code and other documentation used a range of 0-100. This has been consistently changed to 0-100. 1.0.2: Thu Nov 23 1:41:00 PDT 2006 / Ben Pfaff - Fix version number reported by fm and fmscan programs, as well as the version number included in the manpages. Bug report by "Petr Slansky" . - No functional changes. 1.0.1: Sat Oct 7 1:05:00 PDT 2006 / Ben Pfaff - Make fm able to sleep for a user-specified time, or forever, after applying settings. This makes fm usable with radio tuner drivers that turn off the radio after the fd used for tuning is closed. Idea and patch from Dave Ulrick . 1.0: Sat Sep 3 12:21:00 PDT 2004 / Ben Pfaff - New maintainer. New home page is http://benpfaff.org/fmtools - Updated email addresses. - Integrated Debian packaging. - Made fmscan threshold configurable from command line. - Use videodev.h header detached from kernel to avoid including kernel headers. 0.99.1: Fri Aug 16 23:08:30 CDT 2002 / Russell Kroll - fm, fmscan: fix the FSF's address in the headers Fri Aug 16 23:07:49 CDT 2002 / Russell Kroll - COPYING: put in the modern version of the GPL v2, with the correct address for the FSF. Fri Aug 16 23:05:33 CDT 2002 / Russell Kroll - Makefile: reworked a bunch of stuff, and added such useful things like install targets. Hopefully this will make packaging less of a hack. Fri Aug 16 22:55:41 CDT 2002 / Russell Kroll - fm: do the VIDIOCGAUDIO first so there's always good data in the struct Fri Aug 16 22:48:10 CDT 2002 / Russell Kroll - fm.1: incorporated the man page written by Ben Pfaff. Fri Aug 16 22:47:01 CDT 2002 / Russell Kroll - fm: set va.balance to 32768 rather than relying on whatever junk happens to be in the struct. Reported by ahmet inan. Fri Aug 16 22:43:47 CDT 2002 / Russell Kroll - fm: applied patch from Viktor Rosenfeld to fix the rounding so that channels like 99.95 MHz can be tuned. 0.99.0: Sat Feb 3 22:41:12 CST 2001 - Russell Kroll - Final cleanups for 0.99.0. This source has been sitting around for awhile, so it's probably time to push towards 1.0 and call it done. How much can you do to a pair of radio programs, anyway? Thu Jan 4 17:29:49 CST 2001 - Russell Kroll - fmscan: ioctl/code cleanups, ala fm - fmscan: -d support - fm: -d support for multiple devices (/dev/radio1 and so on) - fm: ioctl results checked, other coding cleanups 0.2.5 and earlier: Mon Apr 12 20:32:13 MDT 1999 - -t option for selecting the tuner on multi-tuner boards (radio-cadet, etc) Wed Feb 3 13:13:01 MST 1999 - fmtools 0.2.4 released - 'devices' target added to Makefile - documentation updated for fmscan and /dev/radio0 - programs now use /dev/radio0 instead of old(er) /dev/radio - fmscan added - small code cleanups - -o added to oneliner usage display Sat Jan 16 23:55:15 MST 1999 - fmtools 0.2.3 released - -o (override frequency range checks) introduced after some l-k discussion Sun Jan 10 22:17:07 MST 1999 - fmtools 0.2.2 released - overflows and negative values during volume changes fixed - exit codes are now sane - the division should now accurately reflect 100% volume Thu Jul 30 08:39:50 MDT 1998 - We now support fine tuning on cards that fly the VIDEO_TUNER_LOW flag. Thanks to Ben Pfaff for this addition. fmtools-2.0.7/Makefile.in0000644000175000017500000006432112217426375012210 00000000000000# Makefile.in generated by automake 1.11.6 from Makefile.am. # @configure_input@ # Copyright (C) 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, # 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011 Free Software # Foundation, Inc. # This Makefile.in is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. @SET_MAKE@ VPATH = @srcdir@ am__make_dryrun = \ { \ am__dry=no; \ case $$MAKEFLAGS in \ *\\[\ \ ]*) \ echo 'am--echo: ; @echo "AM" OK' | $(MAKE) -f - 2>/dev/null \ | grep '^AM OK$$' >/dev/null || am__dry=yes;; \ *) \ for am__flg in $$MAKEFLAGS; do \ case $$am__flg in \ *=*|--*) ;; \ *n*) am__dry=yes; break;; \ esac; \ done;; \ esac; \ test $$am__dry = yes; \ } pkgdatadir = $(datadir)/@PACKAGE@ pkgincludedir = $(includedir)/@PACKAGE@ pkglibdir = $(libdir)/@PACKAGE@ pkglibexecdir = $(libexecdir)/@PACKAGE@ am__cd = CDPATH="$${ZSH_VERSION+.}$(PATH_SEPARATOR)" && cd install_sh_DATA = $(install_sh) -c -m 644 install_sh_PROGRAM = $(install_sh) -c install_sh_SCRIPT = $(install_sh) -c INSTALL_HEADER = $(INSTALL_DATA) transform = $(program_transform_name) NORMAL_INSTALL = : PRE_INSTALL = : POST_INSTALL = : NORMAL_UNINSTALL = : PRE_UNINSTALL = : POST_UNINSTALL = : bin_PROGRAMS = fm$(EXEEXT) fmscan$(EXEEXT) subdir = .

Use if you suspect that the card supports a wider frequency range than its driver believes. .TP .B \-q Quiet mode. Keeps information on station and volume from being printed on standard output. .TP \fB\-d \fIdevice Sets \fIdevice\fR as the device to tune. The default is \fB/dev/radio0\fR. .TP \fB\-t \fItuner Sets \fItuner\fR as the tuner on the selected device to adjust. The default is tuner 0. Most radio devices have only a single tuner. .TP \fB\-T none \fR| \fBforever \fR| \fItime After tuning, sleep for the time specified or forever. Time is specified in seconds by default. A suffix of .B m indicates minutes, .B h indicates hours, or .B d indicates days. .IP The .B -T option is useful with radio card drivers that only maintain the tuner settings while the tuner's file descriptor remains open. Try using this option if running .B fm ordinarily produces only a single "pop" from your speakers. .TP .BI freq Frequency to tune the radio to, in MHz. For instance, \fB88.9\fR specifies a frequency of 88.9 MHz. AM tuner values are also specified in MHz; for instance, 530 kHz would be specified as \fB.530\fR. .TP .BI on Turn the radio on (unmute). .TP .BI off Turn the radio off (mute). .TP .BI volume Specify the desired volume, in percent. Not all radio devices support volume control. .TP .BI + Increase the current volume. .TP .BI - Decrease the current volume. .SH CONFIGURATION .B fm reads \fI$HOME\fB/.fmrc\fR, if it exists, to obtain default settings. Each line may take one of the following forms: .TP .BR VOL \ percent Specifies default volume (default: 12.5%). .TP .BR INCR \ percent Volume increment used for .B + and .B - options (default: 10%). .TP .BR TIME Default sleep time (default: .BR none ). .PP All other lines are ignored. .SH SEE ALSO .TP Additional documentation: .B /usr/share/doc/fmtools/README .TP The fmtools homepage: .B http://benpfaff.org/fmtools .SH AUTHORS Russell Kroll , now maintained by Ben Pfaff .

The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

Most radio devices have only a single tuner. .TP \fB\-s \fIfreq Starting frequency for scan, in MHz. Default: 87.9. .TP \fB\-e \fIfreq Ending frequency for scan, in MHz. Default: 107.9. .TP \fB\-i \fIfreq Increment between scanned channels, in MHz. Default: 0.2. .TP \fB\-t \fIpercent Signal strength threshold to consider a channel. Default: 50%. .TP \fB\-q\fR Quiet mode. Suppresses progress output. .SH BUGS This process can take a while, and results vary greatly depending on the radio card in use. If your card's hardware cannot report signal strength, it will not produce useful results. .PP This program may not do much if your radio card's driver doesn't support fine tuning in 1/16000 MHz offsets. By default, V4L2 assumes 1/16 MHz tuning units, which introduces evil rounding errors on many frequencies. .PP Supports only tuner 0 on any given device. .SH SEE ALSO .TP Additional documentation: .B /usr/doc/fmtools/README .TP The fmtools homepage: .B http://benpfaff.org/fmtools .SH AUTHORS Russell Kroll , now maintained by Ben Pfaff .
