Somes explications

Configure a IR remote is not easy. Each remote have particular driver, table and keymap. Before to start the configuration, you must identified these different information :

• driver (i.e. mceusb)
• table (i.e. rc-rc6-mce)
• keymap (i.e. hauppage)

You can identify this information by running this command :

> ir-keytable
Found /sys/class/rc/rc0/ (/dev/input/event17) with:
	Driver mceusb, table rc-rc6-mce
	Supported protocols: lirc rc-5 rc-5-sz jvc sony nec sanyo mce_kbd rc-6 sharp xmp 
	Enabled protocols: lirc nec 
	Name: Media Center Ed. eHome Infrared 
	bus: 3, vendor/product: 147a:e042, version: 0x1201
	Repeat delay = 500 ms, repeat period = 125 ms

Installation

First Method : You owned a remote with a particular keymap (i.e. Konig CMP-MEDIAREM12)

1. Copy the keymap file in /storage/.config/rc_keymaps/

cp /storage/konig_remote /storage/.config/rc_keymaps/.

2. Copy and rename rc_maps.cfg.sample to rc_maps.cfg :

cp /storage/.config/rc_maps.cfg.sample /storage/.config/rc_maps.cfg

3. Edit rc_maps.cfg to add new line at the end of file :

echo 'mceusb		rc-rc6-mce	konig_remote' > /storage/.config/rc_maps.cfg

4. Fix the permission of rc_maps.cfg

chmod 664 /storage/.config/rc_maps.cfg

⚠️ Important LIRC service won't considere rc_maps.cfg if it is set with incorrect permission.

5. Reboot your system to apply changes

Second Method : You owned a remote with a keymap supported by system (/usr/lib/udev/rc_keymaps)

1. Copy and rename rc_maps.cfg.sample to rc_maps.cfg :

cp /storage/.config/rc_maps.cfg.sample /storage/.config/rc_maps.cfg

2. Edit rc_maps.cfg to add new line at the end of file, with your driver, table and keymap value :

echo 'drivers_name		table_name	keymap_name' > /storage/.config/rc_maps.cfg

3. Fix the permission of rc_maps.cfg

chmod 664 /storage/.config/rc_maps.cfg

⚠️ Important LIRC service won't considere rc_maps.cfg if it is set with incorrect permission.

4. Reboot your system to apply changes
