       ir-keytable - a swiss-knife tool to handle Remote Controllers.


       ir-keytable [OPTION]...


       ir-keytable  is  a  tool  that  lists  Remote  Controller devices, loads rc keymaps, tests
       events, and adjusts other Remote Controller options.

       Rather than loading a rc keymap, it is also possible to set protocol decoders and  set  rc
       scancode to keycode mappings directly.

       Note: You need to have read permissions on /dev/input for most of the options to work.


       -a, --auto-load=CFGFILE
              Auto-load keymaps, based on a configuration file. Only works with --sysdev.

       -c, --clear
              Clears the scancode to keycode mappings.

       -D, --delay=DELAY
              Sets the delay before repeating a keystroke.

       -k, --set-key=SCANKEY
              Set scancode to keycode mapping.

       -p, --protocol=PROTOCOL
              Comma  separated  list  of  kernel  protocols  or BPF protocol to enable. All other
              protocols are disabled.

       -e, --parameter=PARAMETER
              Comma separated list of parameters for the BPF protocol.

       -P, --period=PERIOD
              Sets the period to repeat a keystroke.

       -r, --read
              Read and show the current scancode to keycode mapping.

       -s, --sysdev=SYSDEV
              rc device to control, defaults to rc0 if not specified.

       -t, --test
              test if the rc device is generating events

       -v, --verbose
              Enables debug messages.

       -w, --write=KEYMAP
              Reads the protocols and scancode to keycode  mapping  from  the  KEYMAP  file,  and
              enables those on the rc device.

       -?, --help
              Prints the help message

              Give a short usage message

       -V, --version
              print the v4l2-utils version

       Mandatory  or  optional  arguments  to long options are also mandatory or optional for any
       corresponding short options. Options can be combined together.

   The options arguments are:
       SYSDEV the rc device as found at /sys/class/rc

       KEYMAP a toml keymap file with a list of protocols and scancodes to keycode mappings.  The
              format is described in rc_keymap(5).

              a set of scancode1=keycode1,scancode2=keycode2.. value pairs

              Comma  separated  list  of  kernel  protocols  to  be  enabled  (case insensitive).
              Supported kernel protocols are: nec, rc-5, rc-6, jvc, sony, sanyo, rc-5-sz,  sharp,
              mce-kbd,  xmp,  imon,  rc-mm,  other,  all.  It  can  also  be a BPF protocol, e.g.
              manchester, pulse_distance, pulse_length.  If it does not match any of these, it is
              taken to be the path of BPF decoder to be loaded.

              Comma separated list of parameters for the BPF protocol being loaded. They have the
              format of name=value, where value is an number.

       DELAY  Delay before repeating a keystroke

       PERIOD Period to repeat a keystroke

              configuration file that associates a driver/keymap name with a keymap file


       On success, it returns 0. Otherwise, it will return the error code.


       To list all connected Remote Controller devices:

       To clean the keycode mapping and use a newer one:
            ir-keytable -c -w /etc/rc_keymaps/nec_terratec_cinergy_xs.toml

       To append more codes to the existing table:
            ir-keytable -w /etc/rc_keymaps/nec_terratec_cinergy_xs.toml

       To read the current scancode to keycode mapping on the second remote controller:
            ir-keytable -s rc1 -r

       To enable NEC protocol and load a BPF protocol, with a parameter for the BPF protocol:
            ir-keytable -p nec,pulse_distance -e pulse_header=9000

       If you do not know what protocol a remote uses, it can be helpful to first  try  with  all
       kernel  decoders  enabled.  The  decoded  protocol  and scancodes will be displayed in the
            ir-keytable -c -p all -t
