IR Control Guide

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.

More updated detail please refer to Raspberry Pi IR Control Expansion Board

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.

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)

sudo sudo nano /boot/config.txt

Add the following content to config.txt

dtoverlay=lirc-rpi,gpio_in_pin=26

Notice: The volumio version under 1.55 please refer to the below step 2 !!!

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

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”\

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

7. Review recording and perform the command

irw

Then press the separate recording button

8. Edit “.lircrc”,and perform the command

sudo pico ~/.lircrc

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

Note: You could refer to the mpc command, add the button and function you need.http://linux.die.net/man/1/mpc)

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 )&

Exit and save, then reboot to realize the NoIR function.
