    [CONFIGURING RASPBIAN JESSIE]

    Version :                 March 2016
    Release date :        2016-03-18
    Kernel version :     4.1
     <1> To ensure that the necessary kernel modules are loaded at boot, ensure your /boot/config.txt file has the entry below …
    pi@raspberrypi ~ {0}nbsp; sudo nano /boot/config.txt
    dtoverlay=iqaudio-dacplus
     
    x400 setting 1
     
    <2> You must enable i2C support for the X400 to operate. On the Raspberry Pi check if you have the following file and if so delete the line containing i2c-bcm2708 and sndsoc-pcm512x.
     
    pi@raspberrypi ~ {0}nbsp;  sudo nano /etc/modprobe.d/raspi-blacklist.conf
     
    Delete or comment out the lines containing the text below if it exists
    blacklist i2c-bcm2708
    blacklist snd-soc-pcm512x
     
    <3> To ensure that the necessary kernel modules are loaded at boot, ensure your /etc/modules file looks the same as below…
    pi@raspberrypi ~ {0}nbsp;  sudo nano /etc/modules
     
    snd_soc_bcm2708
    snd_soc_bcm2708_i2s
    bcm2708_dmaengine
    snd_soc_pcm512x
    snd_soc_iqaudio_dac
     
    x400 setting 2
     
    <4> Flush your filesystem changes and reboot the Raspberry Pi
     
    pi@raspberrypi ~ {0}nbsp;  sync
    pi@raspberrypi ~ {0}nbsp;  sudo reboot
     
    <5> Using your mouse to right click the icon of speaker and select "IQaudioDAC"
     
    iqaudio setting
     
    <6> Installing LIRC 
     
    pi@raspberrypi ~ {0}nbsp;  sudo apt-get install lirc
     
    <7> Add the two lines below to /etc/modules . This will start the modules up on boot. Pin 8 bellow will be used to take the output from the IR sensor. 
     
    pi@raspberrypi ~ {0}nbsp;  sudo nano /etc/modules
         
    lirc_dev
    lirc_rpi gpio_in_pin=17
     
    ir_0
     
    <8> Save your changes by pressing Ctrl-x then Y
     
    <9> If you are using 3.18.x RaspberryPi firmware you must modify one additional file for the lirc-rpi kernel extension to be loaded:
                   
    Edit your /boot/config.txt file 
                 
    pi@raspberrypi ~ {0}nbsp;  sudo nano  /boot/config.txt
     
    and add:
    dtoverlay=lirc-rpi,gpio_in_pin=17
     
    ir_1
     
    <10> Edit /etc/lirc/hardware.conf and have it appear exactly as shown below. 
     
    pi@raspberrypi ~ {0}nbsp;  sudo nano /etc/lirc/hardware.conf
     
    # /etc/lirc/hardware.conf 
    # Arguments which will be used when launching lircd 
    LIRCD_ARGS="--uinput" 
    # 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. 
    DRIVER="default" 
    # usually /dev/lirc0 is the correct setting for systems using udev 
    DEVICE="/dev/lirc0"
    MODULES="lirc_rpi" 
    # Default configuration files for your hardware if any 
    LIRCD_CONF="" 
    LIRCMD_CONF="" 
     
    2
     
    <10> Edit /etc/lirc/hardware.conf and have it appear exactly as shown below. 
     
    pi@raspberrypi ~ {0}nbsp;  sudo nano /etc/lirc/hardware.conf
     
    The highlighted text are the parts that will need changing, though it’s worth checking the rest of the text incase you have a different initial configuration.
     
    <11> Save your changes by pressing Ctrl-x then Y
     
    <12> Reboot the Raspberry Pi
     
    pi@raspberrypi ~ {0}nbsp;  sudo reboot
     
    <13> Run these two commands to stop lircd and start outputting raw data from the IR receiver:
       
    pi@raspberrypi ~ {0}nbsp;  sudo /etc/init.d/lirc stop 
    pi@raspberrypi ~ {0}nbsp;  mode2 -d /dev/lirc0
     
    <14> Point a remote control at your IR receiver and press some buttons. You should see something like this:  
     
    IR_testing
