NAME

irpipe - tool to send data to lircd over /dev/irpipe kernel device.  

SYNOPSIS

irpipe [options] <file

irpipe --read [options] >file

irpipe --filter [options] <infile >outfile

 

DESCRIPTION

irpipe is designed to feed data to lircd(8) over a /dev/irpipe device. It's a tool to enter test data to lircd in a way which is identical to real data from /dev/lirc devices.

irpipe uses two formats: text and binary. The binary format is documented in the mode2(1).

The irpipe driver allows user to set the features returned by the LIRC_GET_FEATURES ioctl. These are documented in lirc(4).

The irpipe kernel device is often not built in packaged lirc versions. See [KERNEL DRIVER] below.

 

OPTIONS

-d --device=driver
Set kernel device, default is /dev/irpipe0.
-b --bin2text
Convert binary data to text.
-t --text2bin
Convert text data to binary.
-s --add-sync
Add long initial sync on converted output. This is often required for lircd to be able to decode data, in particular if keys are not repeated.
-f --filter
Send data from stdin to stdout
-r --read
Send data from kernel device to stdout. This option is experimental and not tested.
-l--length=bits
Set kernel device signal length. This is only meaningful on LIRCCODE device emulation.
-F--features=bitmask
Set the features bitmask, as returned by the LIRC_GET_FEATURES ioctl. See lirc(4) for more.
-h --help
Display usage summary.
-v --version
Display version.

 

KERNEL DRIVER

The irpipe tool is designed to work with the irpipe kernel driver, although the --filter option works without it. This driver is often not built in packaged versions. If this is the case, the driver can be built from sources in the drivers/irpipe directory. This requires kernel sources installed. The drivers/irpipe/README provides information on building and installing the driver.
