IR-KEYTABLE(1) User Commands IR-KEYTABLE(1) NAME ir-keytable - a swiss-knife tool to handle Remote Controllers. SYNOPSIS ir-keytable [OPTION]... DESCRIPTION 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. OPTIONS -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 en- able. 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 --usage 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). SCANKEY a set of scancode1=keycode1,scancode2=keycode2.. value pairs PROTOCOL Comma separated list of kernel protocols to be enabled (case in- sensitive). 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. PARAMETERS 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 CFGFILE configuration file that associates a driver/keymap name with a keymap file EXIT STATUS On success, it returns 0. Otherwise, it will return the error code. EXAMPLES To list all connected Remote Controller devices: ir-keytable 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 output: ir-keytable -c -p all -t BUGS Report bugs to Linux Media Mailing List <linux-media@vger.kernel.org> COPYRIGHT Copyright (c) 2010-2014 by Mauro Carvalho Chehab.
