    AnonymousPi got a reaction from borekon in Configuring Orange PI PC to receive IR/InfraRed   
    Note: Guide Updated May 2017, as I realise that /dev/input/event3 may not always be the IR receiver device on your armbian installation.
     
    Hi All,
     
    I recently bought an Orange PI PC and the best thing I ever did was install Armbian straight away (and donate). Now that I have a bit of spare time, I wanted to configure my Orange PI PC to do something ridiculous like play Rick Ashley 'Never going to give you up' upon pressing the 'red button' on some generic Chinese IR remote for an LED light strip I have in my living room.
     
    Thanks to Armbian, most of the pieces are in place (such as the SunXI IR package) with the distribution, you just need to glue it all together.
     
    However there are few configuration issues with the default Armbian install on the Orange PI PC that need to be adjusted, otherwise you'll encounter infuriating issues such as:
    No IR device existing or being detected (root cause: sunxi-cir module not loaded) No LIRC 'irw' output even after successfully using irrecord (root cause: DRIVER=devinput doesn't work, though it could be my remote), like this poor sod was experiencing.  
    I should also note that this guide on the terrible Orange PI forums, helped me with my issues.
     
    Step 1) Adjust /etc/lirc/hardware.conf
     
    Updated: This guide was originally written for Armbian based on Debian 'Jessie'. The latest Armbian (as at September 2017) is now based on Ubuntu Xenial. This introduces a new lirc package which yet again comes with a broken hardware.conf
     
    For Ubuntu Xenial (September 2017):
     
    The default hardware.conf that comes with Armbian is broken. It's assigning the 'remote' and 'transmitter' to the same device, this breaks everything. Ensure the TRANSMITTER_MODULES="" and TRANSMITTER_DEVICE = ""
    # /etc/lirc/hardware.conf # #Chosen Remote Control REMOTE="None" REMOTE_MODULES="sunxi_cir" REMOTE_DRIVER="default" REMOTE_DEVICE="/dev/lirc0" REMOTE_SOCKET="" # FYI - /run/lirc/lircd will probably be the socket that the system uses REMOTE_LIRCD_CONF="" REMOTE_LIRCD_ARGS="" #Chosen IR Transmitter TRANSMITTER="None" TRANSMITTER_MODULES="" TRANSMITTER_DRIVER="" TRANSMITTER_DEVICE="/dev/null" TRANSMITTER_SOCKET="" TRANSMITTER_LIRCD_CONF="" TRANSMITTER_LIRCD_ARGS="" #Disable kernel support. #Typically, lirc will disable in-kernel support for ir devices in order to #handle them internally. Set to false to prevent lirc from disabling this #in-kernel support. #DISABLE_KERNEL_SUPPORT="true" #Enable lircd START_LIRCD="true" #Don't start lircmd even if there seems to be a good config file #START_LIRCMD="false" #Try to load appropriate kernel modules LOAD_MODULES="true" # Default configuration files for your hardware if any LIRCMD_CONF="" #Forcing noninteractive reconfiguration #If lirc is to be reconfigured by an external application #that doesn't have a debconf frontend available, the noninteractive #frontend can be invoked and set to parse REMOTE and TRANSMITTER #It will then populate all other variables without any user input #If you would like to configure lirc via standard methods, be sure #to leave this set to "false" FORCE_NONINTERACTIVE_RECONFIGURATION="false" START_LIRCMD=""  
    For Debian Jessie (~year 2016):
     
    By default Armbian doesn't have the suxi-cir module enabled at boot-up, but it is available, so you will need to edit hardware.conf to enable this, as well as correct the DRIVER= line and the DEVICE= line, as the defaults in there are WRONG.
     
    Also I suggest commenting out Igor's code in the top five lines. A hardware.conf that works:
    # Cubietruck automatic lirc device detection by Igor Pecovnik #str=$(cat /proc/bus/input/devices | grep "H: Handlers=sysrq rfkill kbd event" | awk '{print $(NF)}') #sed -i 's/DEVICE="\/dev\/input.*/DEVICE="\/dev\/input\/'$str'"/g' /etc/lirc/hardware.conf # /etc/lirc/hardware.conf # # Arguments which will be used when launching lircd LIRCD_ARGS="" #Don't start lircmd even if there seems to be a good config file #START_LIRCMD=false #Don't start irexec, even if a good config file seems to exist. #START_IREXEC=false #Try to load appropriate kernel modules LOAD_MODULES=true # Run "lircd --driver=help" for a list of supported drivers. # 'devinput' driver on Orange PI PC causes NO EVENTS TO OCCUR # via irw for some reason. DRIVER="default" # usually /dev/lirc0 is the correct setting for systems using udev DEVICE="/dev/lirc0" MODULES="sunxi-cir" # Default configuration files for your hardware if any LIRCD_CONF="" LIRCMD_CONF="" Step 2) Restart lircd service
      As lirc is actually already running and installed in Armbian, do the following:
     
    root@orangepipc:/etc# /etc/init.d/lirc stop root@orangepipc:/etc# /etc/init.d/lirc start To reboot the service. 
     
    Then perform an 'lsmod' to see if it loaded the sunxi_cir module (because otherwise nothing will work):
      user@orangepipc:~$ lsmod Module                  Size  Used by mali_drm                2732  1 drm                   178255  2 mali_drm mali                  123208  0 ump                    29379  3 mali sunxi_cir               1601  0 8189es               1076034  0   Step 3) Find out what '/dev/input/eventX' device is your IR receiver   If you do a: ls /dev/input/event* You will most likely get a bunch of possible event devices to choose from, for example:
    anonymouspi@orangepipc:~$ ls /dev/input/event* /dev/input/event0 /dev/input/event2 /dev/input/event4 /dev/input/event1 /dev/input/event3 /dev/input/event5 For my installation, /dev/input/event3 is the IR receiver, but if you have other devices installed (i.e. USB cameras, keyboards etc.) then the number could be different. For example, executing 'evtest /dev/input/event3' reveals:
    Input driver version is 1.0.1 Input device ID: bus 0x19 vendor 0x1 product 0x1 version 0x100 Input device name: "sunxi-ir" A device name of 'sunxi-ir' means that we are using the right device for the purposes of evtest
        Step 4) Do a quick test with with 'evtest' (OrangePI PC armbian seems to use /dev/input/event3 for IR input )   Armbian has the 'evtest' program installed, point the IR remote (in my case a  LED colour remote) at your Orange PI PC and as root 'evtest /dev/input/event3'.   root@orangepipc:/etc# evtest /dev/input/event3 Input driver version is 1.0.1 Input device ID: bus 0x19 vendor 0x1 product 0x1 version 0x100 Input device name: "sunxi-ir" Supported events:   Event type 0 (EV_SYN)   Event type 1 (EV_KEY)     Event code 152 (KEY_SCREENLOCK)   Event type 4 (EV_MSC)     Event code 4 (MSC_SCAN) Key repeat handling:   Repeat type 20 (EV_REP)     Repeat code 0 (REP_DELAY)       Value    500     Repeat code 1 (REP_PERIOD)       Value    125 Properties: Testing ... (interrupt to exit)  
    Pressing the remote reveals events like:
    Testing ... (interrupt to exit) Event: time 1472917554.113967, type 4 (EV_MSC), code 4 (MSC_SCAN), value 58 Event: time 1472917554.113981, -------------- EV_SYN ------------ Event: time 1472917554.464390, type 4 (EV_MSC), code 4 (MSC_SCAN), value 59 Event: time 1472917554.464398, -------------- EV_SYN ------------ Event: time 1472917554.842832, type 4 (EV_MSC), code 4 (MSC_SCAN), value 45 Event: time 1472917554.842839, -------------- EV_SYN ------------ Event: time 1472917555.345584, type 4 (EV_MSC), code 4 (MSC_SCAN), value 58 That was the red, green, blue and white buttons being pressed. This is a good news.
     
     
    Step 5) Configure lirc to map IR input to key presses or events.
     
    Again, Armbian has irrecord installed (great work Igor), but given I'm re-using this remote to configure the output of a LED strip I have, I'll need to map the IR data sent, to something more meaningful. In other use-cases this isn't generally required as lircs provides a database of media remotes which is pre-mapped to Linux commands/keyboard keys.
     
    There's plenty of information on how to use irrecord, command I used was:
    /etc/init.d/lirc stop ...to first stop the service, then:
    irrecord -H default -d /dev/lirc0 /etc/lirc/lircd.conf ... to record my remote and bind to 'keys'.
     
     
    Step 6) Test with irw
     
    Now that I recorded my configuration file with irrecord:
    /etc/init.d/lirc start .. to start lird service again
     
    then type 'irw' and check that the key mapping works when I point the remote at the Orange PI PC and press a button:
    root@orangepipc:/etc# irw 0000000000ff1ae5 00 KEY_R /etc/lirc/lircd.conf 0000000000ff1ae5 01 KEY_R /etc/lirc/lircd.conf 0000000000ff9a65 00 KEY_G /etc/lirc/lircd.conf 0000000000ff9a65 01 KEY_G /etc/lirc/lircd.conf 0000000000ffa25d 00 KEY_B /etc/lirc/lircd.conf 0000000000ffa25d 01 KEY_B /etc/lirc/lircd.conf 0000000000ff22dd 00 KEY_W /etc/lirc/lircd.conf 0000000000ff22dd 01 KEY_W /etc/lirc/lircd.conf Hoo Ray!
      Step 7) Create a /etc/lirc/lircrc file to run commands
     
    sudo vi /etc/lirc/lircrc I'd actually call mpv here and call the player:
    # http://www.lirc.org/html/configure.html begin    button = KEY_R    prog = irexec    config = mpv  /home/root/Rick\\ Astley\\ -\\ Never\\ Gonna\\ Give\\ You\\ Up.m4a & echo "COMMENT RICK ROLLING" & end begin    button = KEY_W    prog = irexec    config = killall mpv & echo "SADFACE!" & end begin    button = KEY_B    prog = irexec    config = mpv http://sj256.hnux.com & end   You could also create a file for each user of the system if you want, eg: /root/.lircrc, /home/userXXX/.lircrc However if you do this, you will need to start the irexec service manually. If you have a /etc/lirc/lircrc file, the irexec service will start automatically at boot - this service is what actually converts the key press to the command.     So there you go, Rickrolling with a simple press of the red (KEY_R) button :-)

    Hi,
     
    Just joined to say thanks to all to those that are involved in the development of Armbian. I recently bought an Orange Pi PC after reading the internet full of people bitching about non-booting devices, HDMI issues, overheating and general crapness.
     
    Decided to buy a Orange Pi PC nonetheless, found an old crap micro SD card, burnt Armbian (the internet has made it clear to not bother with the crap on the official Orange Pi website!) onto it and the thing booted without any issues! Typing this message from it as we speak in Iceweasel!
     
    The thing only cost me 9 quid, so decided to donate what I would have wasted in cash on a Raspberry Pi 3 (which is anything but the 25 dollar SBC it seems to be advertised) as a donation to Igor and co.
     
    I just run the Orange Pi PC out of the plastic static bag it came in LOL!
     
    Once again, great work.

    Yes, thank you! I have run into some very specific issues (wifi and screen resolution), but a quick search of the forums troubleshoots these quite well. My main problems is that I am a Linux noob, so there is a general learning curve beyond my hardware understanding.
     
    Thanks again!

    Please be careful, this is about the GbE equipped boards which use an external RTL8211E PHY (responsible for a huge increase in consumption if needed). I would suspect in this case it's a different simple hardware issue.
