ir−keytable − a swiss−knife tool to handle Remote Controllers.
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]
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.
−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
On success, it returns 0. Otherwise, it will return the error code.
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
