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 lirc(4) manual page. The text format is as defined in 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 emula‐ tion. -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.
