Append this to your I attached a Raspberry PI (Model B) via HDMI to my LG 42LH9000<\/a>, a 42″ LED-TV from 2009. With the newest version of OpenELEC 4.0.0<\/a>, I was suprised to find out that the most commands via CEC work out nicely. The only trouble I had was, that the „Back“ and „Exit“-Buttons didn’t work at all. Instead, I had to press „STOP“ and „OK“ directly after each other in a short time for „Back“ and „STOP“ and „PAUSE“ for an „Exit“.<\/p>\n As I was using an IR remote control anyways, I thought the raspberry could receive the data for the two missing buttons directly. At first, I needed an IR receiver diode. That was easy, as I still had an old, broken mini-helicopter which was steered using IR. As the helicopter itself was useless, I desoldered the IR receiver. I couldn’t make out a model number, so I simply guessed.<\/p>\n Facing the side with the receiver (that’s the side with the little bump), you can see three legs coming out of it. The left one I used for „DATA“, the middle one for „GND“ and the right one for „Vs“. As the helicopter was working with a lithium battery, I simply guessed that the receiver will work out nicely with only 3.3V.<\/p>\n Next step was wiring the receiver to the Raspberry PI. I needed +3.3V, GND and a useful GPIO-pin. Searching the web, I found this great view of the GPIOs. I’m sorry that I can’t give any credit to the one who created this graphic, as there are no copyright notices anywhere to find.<\/p>\n I attached the left („DATA“)-leg to GPIO 23, the middle leg to GND and the right leg („Vs“) to +3.3V.<\/p>\n After logging into my Raspberry PI, which was already running OpenELEC, I tried these commands to test if the IR receiver was working:<\/p>\n The Now we want to make sure that the receiver is actually working. Grap your remote control, run this command and see if anything happens on the console.<\/p>\n This is my example output when I hit the „BACK“-Button on my remote control:<\/p>\n The IR receiver actually works and we just saw the RAW input from the sensor!<\/p>\n To make sure that the next time the Raspberry PI is started, that the module is loaded correctly, type in this command:<\/p>\n Make sure that no LIRCD is running:<\/p>\n And start recording the input from the two buttons:<\/p>\n The last command guides you through a wizard, the two buttons are called As a result, you should have a file As you can see I really only added the two buttons that I still needed. If you want to add any more buttons, you must know the correct names for them. These can be retrieved with a simple command. As there are MANY possible buttons available, I limit the output to those which might be useful for me. The following command for example shows me the „EXIT“-Button:<\/p>\n I assigend my „BACK“-Button from the remote to „KEY_EXIT“, as this works like a „back-button“ within KODI. The „EXIT“-Button from my remote is used as a „MENU“ key.<\/p>\n If you want to know which buttons are used by KODI (and in what manner), the answers lie inside the file Now copy the file to the correct location:<\/p>\n And reboot:<\/p>\n If you want to add other keys, which are normally not part of the remote control, here are the steps to work it our correctly:<\/p>\n Make sure that you have the Lircmap.xml from the system in your storage:<\/p>\n And add in the last section which starts with Here are the links that helped me set this up: UPDATE: Newest kernels require you to add the GPIO-Information directly into the config.txt, otherwise the LIRC won’t be available: Append this to your \/boot\/config.txt (if you attach the IR receiver to GPIO 23 as stated in the article below): dtoverlay=lirc-rpi,gpio_in_pin=23 I attached a Raspberry PI (Model B) via HDMI to my LG 42LH9000, a 42″ … Raspberry Pi on LG 42LH9000 with OpenELEC and IR Remote<\/span> weiterlesen \/boot\/config.txt<\/code> (if you attach the IR receiver to GPIO 23 as stated in the article below):<\/p>\ndtoverlay=lirc-rpi,gpio_in_pin=23\r\n<\/pre>\n
