Usage: ir-ctl [OPTION...] --features
or: ir-ctl [OPTION...] --receive
or: ir-ctl [OPTION...] --send [file to send]
or: ir-ctl [OPTION...] --scancode [scancode to send]
or: ir-ctl [OPTION...] --keycode [keycode to send]
or: ir-ctl [OPTION...] [to set lirc option]
Receive IR, send IR and list features of lirc device
You will need permission on /dev/lirc for the program to work
On the options below, the arguments are:
DEV - the /dev/lirc* device to use
FILE - a text file containing pulses and spaces
CARRIER - the carrier frequency to use for sending
DUTY - the duty cycle to use for sending
EMITTERS - comma separated list of emitters to use for sending, e.g. 1,2
GAP - gap between sending in microseconds
RANGE - set range of accepted carrier frequencies, e.g. 20000-40000
TIMEOUT - set length of space before receiving stops in microseconds
KEYCODE - key code in keymap
SCANCODE - protocol:scancode, e.g. nec:0xa814
KEYMAP - a rc keymap file from which to send keys
Note that most lirc setting have global state, i.e. the device will remain
in this state until set otherwise.
-d, --device=DEV lirc device to use
-f, --features list lirc device features
-K, --keycode=KEYCODE send IR keycode from keymap
-r, --receive receive IR to stdout
-s, --send=FILE send IR pulse and space file
-S, --scancode=SCANCODE send IR scancode in protocol specified
-v, --verbose verbose output
Receiving options:
-1, --one-shot end receiving after first message
--mode2 output in mode2 format
-m, --measure-carrier report carrier frequency
-M, --no-measure-carrier disable reporting carrier frequency
-n, --narrowband use narrowband receiver, disable learning mode
-R, --carrier-range=RANGE set receiver carrier range
-t, --timeout=TIMEOUT set receiving timeout
-w, --wideband use wideband receiver aka learning mode
Sending options:
-c, --carrier=CARRIER set send carrier
-D, --duty-cycle=DUTY set send duty cycle
-e, --emitters=EMITTERS set send emitters
-g, --gap=GAP set gap between files or scancodes
-k, --keymap=KEYMAP use keymap to send key from
-?, --help Give this help list
--usage Give a short usage message
-V, --version Print program version
Mandatory or optional arguments to long options are also mandatory or optional
for any corresponding short options.
