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

## Streamzap PC Remote (USB)

This particular remote is known to not function with the lirc-utils package included lirc.service. Flyspray #37958 has been created. Until it is acted upon, users can create a custom service file that does work:

    /etc/systemd/system/my-lirc.service

    [Unit]
    Description=LIRC Daemon
    After=network.target

    [Service]
    Type=forking
    PIDFile=/run/lirc/lircd.pid
    ExecStartPre=/bin/mkdir -p /run/lirc
    ExecStartPre=/bin/rm -f /dev/lircd
    ExecStartPre=/bin/rm -f /run/lirc/lircd
    ExecStartPre=/bin/ln -s /run/lirc/lircd /dev/lircd
    ExecStart=/usr/bin/lircd -d /dev/lirc0 -P /run/lirc/lircd.pid
    ExecStopPost=/bin/rm -f /dev/lircd
    ExecStopPost=/bin/rm -fR /run/lirc

    [Install]
    WantedBy=multi-user.target

Note: When the batteries in this remote are low, it may stop working even though the red LED on the received still flashes upon receiving signals!
