====== Suppport Custom Remote Controller ======
**This is experimental feature, not supported officially yet. But it should work well with V1.4 or later Ubuntu release**
===== Install package =====
Install **Lirc** package. While installing **lirc**, you will be asked the device type of IR receiver and transmitter. Since we will set up this later by manual, you can select **None**.
$ sudo apt-get install lirc
===== Registering own remote controller =====
**Lirc** package provide a tool, **irrecord**, to help registering the buttons of own remote controller. Once the tool is started, for example, you will be asked to press the buttons and it will analyse the signals of your remote controller like protocol type or headers. After this analysis you can start register the buttons one by one.
$ sudo irrecord --device /dev/lirc0 lircd.conf
Once signal analysis is done, you will be asked with the message below to enter the button name to register and press the applicable button. In this step, you can register many buttons as much as you expect to register. If you done, just press enter key on the prompt.
Please enter the name for the next button (press to finish recording)
The tool would ask you more steps to finalize and store the configuration file with the below message.
Successfully written config file.
For example, if you have done whole steps successfully with Hardkernel's stock remote controller, your will have the configuration file like below very similiary.
Now you must copy the configuration file, **lircd.conf**, to **/etc/lirc/** so that **lirc** service can recognize the button.
$ sudo cp lircd.conf /etc/lirc/lircd.conf
===== Lirc configuration =====
Now you will need to modify **/etc/lirc/hardware.conf** to specify the configuration to run as a daemon.
$ sudo vi /etc/lirc/hardware.conf
Specify the kernel driver module and its node to read IR signal.
5 REMOTE_MODULES="meson-ir"
6 REMOTE_DRIVER="default"
7 REMOTE_DEVICE="/dev/lirc0"
As well as below to make **lircd** start on boot.
28 START_LIRCD="true"
In order to apply key event to whole system, enable **Userspace Input Event** while adding **--uinput** as a parameter of **lircd**.
10 REMOTE_LIRCD_ARGS="--uinput"
All necessary configuration is done, you can simply start the service **lirc** by command line or reboot the device.
$ sudo service lirc start
* Loading LIRC modules [ OK ]
* Starting remote control daemon(s) : [ OK ]
===== Testing =====
If the **Lirc** daemon is running and drivers are loaded properly, you can test if your remote controller is accepted by the tool **irw**.
odroid@odroid:~$ irw

000000004db2837c 00 KEY_RIGHT myremote.conf
000000004db24bb4 01 KEY_DOWN myremote.conf
000000004db2738c 00 KEY_OK myremote.conf
You can check if the daemon is running properly.

As well as necessary drivers are loaded.
