IR-KEYTABLE(1)                   User Commands                  IR-KEYTABLE(1)

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

       ir-keytable [OPTION]... --device [/dev/input/event* device]
       ir-keytable [OPTION]... --sysdev [rc class (f. ex. rc0)]
       ir-keytable [OPTION]... [for using the rc0 sysdev]

       ir-keytable is a tool that lists the Remote Controller devices, allows
       one to get/set rc keycode/scancode tables, set protocol decoder, test
       events generated by a rc device, and to adjust other Remote Controller

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

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

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

       -d, --device=DEV
              Use specified input device.

       -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

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

       -v, --verbose
              Enables debug messages.

       -w, --write=TABLE
              Reads the protocols and scancode to keycode mapping from the
              TABLE 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

   The options arguments are:
       DEV    the /dev/input/event* device to control

       SYSDEV the rc class as found at /sys/class/rc

       TABLE  a toml file with a list of protocols and scancode to keycode

              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, other,
              all. It can also be a BPF protocol, e.g. manchester, rc_mm,
              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

       DELAY  Delay before repeating a keystroke

       PERIOD Period to repeat a keystroke

              configuration file that associates a driver/table 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 table 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 keytable, 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
