This article includes device specific examples of LIRC function configurations.

Asus DH Deluxe series motherboard

Check the output of:

$ cat /dev/usb/hiddevX

where X is 0,1 or bigger, and press some buttons on remote. If characters result, then the device is working, follow steps:

1. In file /etc/conf.d/lircd.conf add:

LIRC_DRIVER="dvico"

2. Reload LIRC:

# systemctl restart lirc

ASRock ION series (Nuvoton) quickstart

$ ln -s /usr/share/lirc/remotes/lirc_wb677/lircd.conf.wb677 /etc/lirc/lircd.conf
# systemctl restart lirc

Logitech Wireless Presenter R400

The R400 Presenter can be used with default configuration from devinput. Follow the following steps to be able to use the following buttons: KEY_PAGEDOWN KEY_PAGEUP KEY_DISPLAYTOGGLE KEY_PRESENTATION.

1. Copy the default devinput configuration which should work out of the box for the R400:

# cp /usr/share/lirc/devinput/lircd.conf.devinput /etc/lirc/lircd.conf

2. Create the following Udev rule to create the correct symlink whenever you connect your presenter:

/etc/udev/rules.d/99-logitech-r400-lirc.rules
[Service]
ExecStart=
ExecStart=/usr/bin/lircd --driver=devinput --device=/dev/input/ir

3. Create the lirc service configuration file to start the lirc service with the correct settings for your presenter whenever you want to transform it into a remote control:

/etc/systemd/system/lirc.service.d/logitech-r400.conf
[Service]
ExecStart=
ExecStart=/usr/bin/lircd --driver=devinput --device=/dev/input/ir

3. Use systemctl start lirc.service to start lirc and irw to test whether your keys are recognised:

$ irw
000000008001006d 00 KEY_PAGEDOWN devinput
0000000080010068 00 KEY_PAGEUP devinput
00000000800101af 00 KEY_DISPLAYTOGGLE devinput
00000000800101a9 00 KEY_PRESENTATION devinput

4. Create your program-specific configurations as described here.

Serial Port "Home Brew" IR Receiver

1. Create a udev rule to give non-privleged users read/write access to the serial port. In this example, ttyS0 is used.

/etc/udev/rules.d/z98-serial.rules
# For serial port ttyS0 and LIRC
KERNEL=="ttyS0",SUBSYSTEM=="tty",DRIVERS=="serial",MODE="0666"

2. Create the needed modprobe configs

/etc/modules-load.d/lirc_serial.conf
lirc_serial
/etc/modprobe.d/lirc_serial.conf
install lirc_serial /usr/bin/setserial /dev/ttyS0 uart none && /sbin/modprobe --first-time --ignore-install lirc_serial
options lirc_serial type=0
remove lirc_serial /sbin/modprobe -r --first-time --ignore-remove lirc_serial && /sbin/modprobe -r lirc_dev
Note: Using udev rules to run the setserial command does not work in my experience because lirc_serial gets loaded before the serial port rules are applied.

3. Install a custom systemd service file.

/etc/systemd/system/lirc.service
[Unit]
Description=Linux Infrared Remote Control
After=network.target

[Service]
Type=simple
PIDFile=/run/lirc/lircd.pid
ExecStartPre=/bin/rm -f /dev/lirc /dev/lircd /var/run/lirc/lircd
ExecStart=/usr/sbin/lircd -n -r -P /run/lirc/lircd.pid -d /dev/lirc0 -o /run/lirc/lircd
ExecStartPost=/usr/bin/ln -sf /run/lirc/lircd /dev/lircd
ExecStartPost=/usr/bin/ln -sf /dev/lirc0 /dev/lirc
ExecReload=/bin/kill -SIGHUP $MAINPID

[Install]
WantedBy=multi-user.target

4. We still need the default tmpfiles to be created, so copy that config file to /etc/tmpfiles.d/lirc.conf.

# cp -a /usr/lib/tmpfiles.d/lirc.conf /etc/tmpfiles.d/lirc.conf

5. Create a ~/.lircrc or a /etc/lirc/lircrc file for system wide use.

6. Have the service start at boot and then test with a reboot

# systemctl enable lirc.service
# systemctl reboot

or load the module and start the lirc.service.

# modprobe lirc_serial
# systemctl start lirc.service
