[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=""

<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:
