       lircd.conf - lirc main configuration file


       The  file  has  two purposes: to provide timing information to the driver so it can decode
       the data to button presses, and to provide a mapping from button presses  to  key  symbols
       used by lircd(8).

       The  basic  structure  is a list of remote blocks.  Whitespace and line breaks are used as

       If the comment character (#) appears as the first character on a line the rest of the line
       is ignored.


       Remote blocks are either normal or raw.

       Normal  remote blocks begin with begin remote and ends with end remote.  The first part of
       the block describes the basic properties of the remote, see  REMOTE  DESCRIPTION  SECTION.
       Following this is a codes section, which is delimited by begin codes and end codes.

       Each  line  in  a  codes section contains the name of a button on the remote followed by a
       hexadecimal data value matching the data part of the  IR  frame  (see  REMOTE  DESCRIPTION
       SECTION). You may not assign the same name to two buttons in the same remote section.

       Raw remote blocks are identical to normal blocks besides the codes section which is a list
       of button descriptions enclosed by begin raw_codes and end raw_codes.

       A raw button description begins with the parameter  name  followed  by  the  name  of  the
       button.  The  button  description  ends with the next button description or the end of the
       raw_codes block. The lines in between is a list of decimal numbers describing  the  signal
       sent  by  that  button.  The  first  number  indicates  the duration of the first pulse in
       microseconds.  The second number indicates the duration of the  space  which  follows  it.
       Pulse  and space durations alternate for as long as is necessary. The last duration should
       represent a pulse.


       Each line in this section contains a parameter followed by the value or values that should
       be assigned to that parameter. Parameters are optional unless otherwise stated.

       All  values  are  decimal  integers  that  are  either  dimensionless  or  have  units  of
       microseconds unless otherwise stated. Hexadecimal numbers should be prefixed by 0x. If the
       remote does not have a particular "feature," then the line may be omitted. The button code
       is sent just after the pre signal and just before the post signal.

       Some parameters describe the bits in the IR protocol. The frame is normally defined like

              |header|plead|pre data|pre|data|post|post data|ptrail|foot|gap|

       where most parameters defaults to 0. Some parameters change the overall  frame  layout  e.
       g., the repeat parameter.

       include ”<path>”
           Include  the  given path using normal include semantics. If the path is relative, it's
           interpreted relative to the main lircd.conf file. <path> must be  enclosed  in  double
           quotes.  It  can  contain  a  glob(3)  pattern  in  which  case all matching files are

       manual_sort <1|0>
           Normally, lircd tries to sort multiple remotes so the one which  decodes  fastest  are
           used  first. Setting manual_sort to 1 in any remote disables this and uses the remotes
           in the order they are listed in lircd.conf or as the alphanumerically sorted filenames
           in lircd.conf.d.

       name <remote name>
           The unique name assigned to the remote control (may not contain whitespace).  Within a
           single file all names must be unique. Parameter is mandatory.

       suppress_repeat <repeats>
           Suppress a given number of repeats for all buttons in  this  remote.  Defaults  to  0,
           which  means  that  no  repeats  are  suppressed. Note that lircrc has a corresponding
           repeat parameter which can be used to  suppress  repeats  for  specific  button/client

       flags <flag1><|flag2>...
           Flags  are  special  text  strings which describe various properties of the remote and
           determine the semantics of some of the following fields.   Multiple  flags  should  be
           separated by the pipe(|) symbol.  See FLAGS.

       driver <driver name>
           For  lirccode  drivers  which  does  not  have  timing information the optional driver
           attribute names the driver which is required to use this remote.

       bits <number of data bits>
           The number of data bits in the hexadecimal codes which describe each  button  (decimal

       eps <relative error tolerance>
           The relative error tolerance for received signals in percent. By default, irrecord set
           this to 30 (i. e., 30%).

       aeps <absolute error tolerance>
           The absolute error tolerance for received signals (microseconds). The default  is  the
           hardcoded driver dependent resolution value. By default irrecord sets this to 100.

       header <phead> <shead>
           The initial pulse and space sent (microseconds).

       three <pthree> <sthree>
           Only used by RC-MM remotes

       two <ptwo> <stwo>
           Only used by RC-MM remotes

       one <pone> <sone>
           The pulse and space lengths representing a one.

       zero <pzero> <szero>
           The pulse and space lengths representing a zero.

       ptrail <trailing pulse>
           A trailing pulse, immediately following the post_data.

       plead <leading pulse>
           A leading pulse, immediately after the header.

       foot <pfoot> <sfoot>
           A pulse and space, immediately following the trailing pulse.

       repeat <prepeat> <srepeat>
           A  pulse  and  space  that  replaces everything between leading pulse and the trailing
           pulse, whenever a signal is repeated. The foot is not sent, and the header is not sent
           unless the REPEAT_HEADER flag is present.

       pre_data_bits <number of pre_data_bits>
           The number of bits in the pre_data code.

       pre_data <hexadecimal number>
           Hexadecimal  code  indicating the sequence of ones and zeros immediately following the
           leading pulse.

       post_data_bits <number of post data bits>
           The number of bits in the post_data code.

       post_data <hexadecimal number>
           Hexadecimal code indicating the sequence of ones and zeros immediately  following  the
           post signal.

       pre <ppre> <spre>
           A pulse and space immediately following the pre_data.

       post <ppost> <spost>
           A pulse and space immediately following the button code.

       gap <gap length>
           A (typically long) space which follows the trailing pulse.

       repeat_gap <repeat_gap length>
           A gap immediately following the trailing pulse, and preceding a repetition of the same
           code that's due to a the same press of the button.

       min_repeat <minimum number of repetitions>
           The minimum times a signal is repeated when sent. Note that 0 means the signal is sent
           only once. Not used when receiving.

       toggle_bit <bit to toggle>
           A  bit  of  the pre_data, code, or post_data that is toggled between one and zero each
           time a button is pressed. This parameter is obsoleted by toggle_bit_mask and should be
           used in new configs.

       toggle_bit_mask <hexadecimal mask>
           Bits  which are  toggled between one and zero each time a button is pressed.  The mask
           is applied to the concatenated value of pre data - data - post_data.

       repeat_mask <mask>
           Mask defines which bits are inverted for repeats.

       frequency <hertz>
           Remote carrier frequency, defaults to 38000.

       duty_cycle <on time>
           The percentage of time during a pulse that infrared light is being sent.  This  is  an
           integer between 1-100 inclusive.  default is 50.


       Flags are values set in the flags parameter.

       RC5 The remote uses the RC5 protocol.

       RC6 The remote uses the RC6 protocol.

           The remote uses the RC-MM protocol.

           Obsolete  flag,  now a synonym for RC5. The position of the pulse (before or after the
           space) determines whether the bit is a one or a zero.

           A one and a zero can be distinguished by the length of the spaces,  used  by  the  NEC
           protocol and others.

           Reverses  the  bit  order  of  the  pre_data, the post_data and the codes (e.g., 0x123
           becomes 0xC48). If this flag is present, the least significant bit is sent first.

           The header is not sent when a signal (the button is held down) is repeated even though
           there is no special repeat code.

           The  foot  is not sent when a signal is repeated (the button is held down) even though
           there is no special repeat code .

           The total signal length is always constant. The gap length now represents  the  length
           of  the  entire  signal,  and  the  actual  gap  at  the end of the signal is adjusted

           The codes are in raw format.

           Send the header when the signal is repeated even  though  the  remote  has  a  special
           repeat code.


       LIRC was designed to collect IR data and save it in a private, compact, yet human readable
       format with the purpose of being able to re-transmit (or re-recognize) these  signals.  It
       was  not  designed  with  the goal of providing a well documented and tested configuration
       file format that could be used e.g., to generate arbitrary IR signals or to  convert  them
       to  other formats. The configuration file should thus not be considered a public interface
       to LIRC.

       This manpage should be understood with this in mind. It was authored by reading  the  code
       of  LIRC,  and  does not constitute an authoritative specification of the behavior of LIRC
       and its configuration file.  Also, some less commonly used flags and  parameters  are  not
