IR−KEYTABLE

NAME

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

SYNOPSIS

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

DESCRIPTION

ir−keytable is a tool that lists the Remote Controller devices, allows one to get/set IR keycode/scancode tables, test events generated by IR, and to adjust other Remote Controller options.

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

OPTIONS

−a, −−auto−load=CFGFILE

Auto−load a table, based on a configuration file. Only works with sysdev.

−c, −−clear

clears the old table

−d, −−device=DEV

ir device to control

−D, −−delay=DELAY

Sets the delay before repeating a keystroke

−k, −−set−key=SCANKEY

Change scan/key pairs

−p, −−protocol=PROTOCOL

Protocol to enable (the other ones will be disabled). To enable more than one, use the option more than one time

−P, −−period=PERIOD

Sets the period to repeat a keystroke

−r, −−read

reads the current scancode/keycode table

−s, −−sysdev=SYSDEV

ir class device to control

−t, −−test

test if IR is generating events

−v, −−verbose

enables debug messages

−w, −−write=TABLE

write (adds) the scancodes to the device scancode/keycode table from the specified TABLE file

−?, −−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:

DEV

the /dev/input/event* device to control

SYSDEV

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

TABLE

a file wit a set of scancode=keycode value pairs

SCANKEY

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

PROTOCOL

protocol name to be enabled (case insensitive). Supported protocols are: NEC, RC-5, RC-6, JVC, SONY, SANYO, LIRC, RC-5-SZ, SHARP, MCE-KBD, XMP, other, all.

DELAY

Delay before repeating a keystroke

PERIOD

Period to repeat a keystroke

CFGFILE

configuration file that associates a driver/table 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 table and use a newer one:
ir−keytable −c −w /etc/rc_keymaps/nec_terratec_cinergy_xs

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

To read the current keytable, on the second remote controller: ir−keytable −s rc1 −r
