== Introduction ==
The HIFI DAC/ DIGI expansion board specific for Raspberry Pi. It adopts the I2S interface rather than the USB port.It can build up online HIFI Player with Audio Player System(eg: volumio, xbmc and so on).
The two output interface can connect with external Amplifier appliances, which can get rids of big consumption of PC, slowly power on/off, big power noise and so on.

==Tutorial ==
1. First Preparation: Burn in volumio system and install HIFI expansion board
* Start up Raspberry Pi, and log in via online SSH method. (User: pi password: Raspberry)
* Update and install lirc softwarem, and perform the following command:
''sudo apt-get update''
''sudo apt-get install lirc''

2. Edit config.txt and add configuration.
<font color="#FF0000">PS: For the those expansion board such as [[DAC II]], [[DAC+]], [[DiGi+]] or [[Stepper/Motor/Servo Robot Expansion Board SKU:418460]], only exist Receiver no launcher, and gpio_in_pin=26 (GPIO PIN)</font>
''sudo sudo nano /boot/config.txt''
Add the following content to config.txt
''dtoverlay=lirc-rpi,gpio_in_pin=26''
[[File:DAC3.png|400px]]
<font color="#FF0000">'''Notice: The volumio version under 1.55 please refer to the below step 2 !!!''' </font>
2. Edit Modules, and add configuration.
(DIGI NoIR receiver for Raspberry Pi Model B Board=18; DAC+ receiver for Raspberry Pi B+/ 2B Board=26; DIGI+ receiver for Raspberry Pi B+/ 2B Board=26; )
''sudo nano /etc/modules''
Add the two line content to modules
''lirc_dev''
''lirc_rpi gpio_in_pin=18''
[[File:DAC4.jpg|400px]]
3. Edit the LRIC configuration file to realize the NoIR function
sudo nano /etc/lirc/hardware.conf
Revise the following content
LIRCD_ARGS=”–uinput”
DRIVER=”default”
DEVICE=”/dev/lirc0″
MODULES=”lirc_rpi”
Note: The ”–uinput”,means two "-"
4. Perform “sudo reboot” and reboot Raspberry Pi,and enable the NoIR function.

If it shows like the picture that it' s ok.
5. Record Button
sudo /etc/init.d/lirc stop
sudo irrecord -n -d /dev/lirc0 ~/lircd.conf
Record the remote controller according to the tips. Record separately"pause", “nextsong”,“prevsong”,“stop”,“volumeup”,“volumedown”\
[[File:DAC5_(2).jpg|400px]]
Cover the relative files about lirc software with recorded ~/lircd.conf file
''sudo cp ~/lircd.conf /etc/lirc/lircd.conf''
6. Start up lirc software
''sudo /etc/init.d/lirc start''
[[File:DAC6.jpg|400px]]
7. Review recording and perform the command
''irw''
Then press the separate recording button
[[File:DAC7.jpg|400px]]
8. Edit “.lircrc”,and perform the command
''sudo pico ~/.lircrc''
[[File:DAC7.jpg|400px]]
Add the content to the file:
begin
prog = irexec
button = pause
config = mpc toggle
end
begin
prog = irexec
button = nextsong
config = mpc next;mpc play
end
begin
prog = irexec
button = prevsong
config = mpc prev;mpc play
end
begin
prog = irexec
button = stop
config = mpc stop
end
begin
prog = irexec
button = volumeup
config = mpc volume +1
end
begin
prog = irexec
button = volumedown
config = mpc volume -1
end
[[File:DAC9.jpg|400px]]
<font color="#FF0000">'''Note: You could refer to the mpc command, add the button and function you need.'''(http://linux.die.net/man/1/mpc)</font>
9. Perform the following command to control volumio
''irexec -d''
10. Edit file rc.local,make the NoIR function enable when start up volumio, and perform the command
''sudo nano /etc/rc.local''
Add the content in front of the exit0
''(sleep 3;
sudo -u volumio irexec -d
)&''
[[File:DAC10.png|400px]]
Exit and save, then reboot to realize the NoIR function.
