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.
