RuneAudio as a standalone system on C1+

odroider

Great OS image!
Thanks for your hard work.

I've just made a standalone RuneAudio system with C1+, HiFi-Shield and a 3.2inch TFT LCD.

Because the small LCD has low resolution 320x240, I needed to zoom in.

To enjoy K-pop, I also installed Korean font pack.

Here are brief steps what I did.
Install xorg stuff and lxde desktop
Install some Korean fonts
Install Chromium browser to render the RuneAudio UI on the LCD.
Run the Chromium with kiosk mode and open 127.0.0.1 as URL to display RuneAudio UI to see the feasibility.
Configure the system to enable auto-login to X-window (LXDE) and launch the Chromium automatically.
Add some other stuff in .bash_profile to activate the 3.2inch SPI-TFT LCD and touch screen drivers.
Use the xinput_calibrator for the resistive touch screen calibration.
Finally, the RuneAudio starts fully automatically after just turn on the system.

This is my first experience of using Arch Linux. So I spent a couple of days to find correct packages and configuration files.
It was not easy at all but I learned a lot. Finally my little kids can play music without my phone.

When I have time slot, I will make a very detail instruction how to build this fun and useful item.

Once again, really appreciate the official support of C1+ !

Great job!
I'm really interested in the description, just wonder if this would fit into the HK Cloud Shell somehow.

Yes! 2TB HDD included standalone system will be really fantastic.

But the CloudShell LCD has no touch screen. So I'm very curious how to control the web UI with the IR remote controller.

odroider

I could use HK's official remote controller after issuing below two commands as hondagx35 explained.

systemctl enable lircd
systemctl enable irexec

Volume +/- and Next/Previous keys are working as expected.
But I want to map "OK" key to "Play/Pause" function.
Is there any key-map file I can edit?

EDIT:
Oh! I found the MUTE key toggles Play and Pause.

FastForwad and FastRewind are missing though.
I think UP/DOWN/LEFT/RIGHT/OK keys should be mapped other ways.

Repeated Vol +/- key also should be considered too.
Time to study the LIRC stuff.

/etc/lirc/lircrc

The following functions are included:
- volume up = "+"
- volume down = "-"
- next song = "arrow down" (so it matches to Queue)
- prev song = "arrow up"
- seek forward = "arrow right"
- seek backward = "arrow left"
- toggle play/pause = "mute"
- power down = "power" (4 seconds) + "OK" (2 seconds)
- reboot = "power" (4 seconds) + "arrow up" (2 seconds)
- if player is stopped next or prev song (arrow down or up) starts the player.

As you can see:
- "/etc/lirc/lircd.conf.d/lircd.conf" is the configuration for your remote
- "/etc/lirc/lircrc" maps your keys to mpd functions

Thank you for the configuration files.
It works greatly.

A couple of minor things.
1. The seek speed is too much fast. I changed the skip value to 2 seconds from 5 seconds. It is nice for me.
2. Next track (DOWN key) works very well but Previous track(UP key) doesn't frequently.
After changing the config of KEY_PREVIOUS, it is slightly better now. But I'm not sure.

 
     button = KEY_PREVIOUS
     config = mpc consume off;mpc prev && mpc play

Hi odroider,

inspired by your work i did something similar.
What i did different is:

- used matchbox-window-manager instead of lxde
- used midori instead of chromium

It works great and doesn't consume much resources.

Hello Frank,

Below results were measured when I played 44.1Khz/24bit FLAC music.

[root@runeaudio ~]# free -h

Yes, the matchbox and midori are much more light.

The CPU usage seems to be fine for me because the tiny LCD screen resolution is only 320x240.
In fact, I bought a 480x320 4-inch IPS LCD for better visibility and it will be here early next week.
I will try it with the matchbox and midori too. I need to find how to zoom in/out the UI on the midori.

I want to make a RuneAudio powered network player at around US$200 including C1+, HiFi-Shield, Micro-SD UHS, LCD Screen, Power supply and Aluminium case. Is it really affordable?

I will share all the cost and schematics when it is realized.

Edit.
If we change this Kernel parameter in the boot.ini file, we can have ~110MB of additional system RAM.

# Disable VPU (Video decoding engine, Saves RAM!!!)
# 0 = disabled
# 1 = enabled
setenv vpu "1"

Now, I have enough RAM to play.

and thank YOU for this nice piece of work, any chance on a detail instruction yet?

odroider

I had no time.. Sorry.

Here is brief guide I wrote on my notepad. Please try it ant let me know what's not working or missing.

Let's try it with a HDMI TV or monitor first. I will write another guide for the small 3.2inch TFT LCD later.

Install the RuneAudio OS image for C1+ on your eMMC or SD
RuneAudio_odroid-c1_0.3-dev_20150824_2GB.img

Use the serial console (with ODROID USB-UART kit) or SSH to the IP address given to the board by your router.

Install video driver files (one for HDMI and the other one for TFT-LCD)

pacman -S xf86-video-odroid-c1 xf86-video-fbdev

Install xorg server

pacman -S xorg-server

Install xorg-xinit, which provides both xinit and startx.

pacman -S xorg-xinit

Install lxde Desktop GUI

pacman -S lxde

Install an extra font if you need. I installed Korean font because I want to display the song information in our character set.

pacman -S ttf-baekmuk

Download a working Chromium browser and install it. (Official ALARM package didn't work)

wget http://odroidxu.leeharris.me.uk/chromium-44.0.2403.107-1-armv7h.pkg.tar.xz
sudo pacman -U chromium-44.0.2403.107-1-armv7h.pkg.tar.xz

If you edit /etc/pacman.conf and set

IgnorePkg   = chromium

it won't get upgraded accidentally.

Reboot your ODROID and Run LXDE on the command line on the HDMI screen.

lxdm

Test the RuneAudio UI on the HDMI screen. It should work with below command.

chromium --user-data-dir --kiosk 127.0.0.1

How to do "auto-login" on the HDMI console.
Run

systemctl edit getty@tty1

And copy and paste below lines and save it.

[Service]
ExecStart=
ExecStart=-/usr/bin/agetty --autologin root --noclear %I 38400 linux

How to do "auto-start lxde". Make .bash_profile in /root/ directory with below contents.

#
# ~/.bash_profile
#

echo Run me first
if [[ -z $DISPLAY ]] && [[ $(tty) = /dev/tty1 ]]; then
exec lxdm
fi

Enable auto login of LXDE
"nano /etc/lxdm/lxdm.conf" and edit the second line like this

## uncomment and set autologin username to enable autologin
autologin=root

Auto start the Chromium browser in full screen mode
Edit this file.

nano /etc/xdg/lxsession/LXDE/autostart

Add this line at the end.

@chromium --user-data-dir --kiosk 127.0.0.1

You can see the RuneAudio Web UI on the HDMI just after power-on your ODROID fully automatically.

If it works, I will prepare an additional instruction to work with 3.2inch TFT screen as well as touch screen.

Hi odroider,

thank you for your work and for sharing it.

@all
The coming 0.4 for ODROID and RP2 will have a local browser integrated.

Frank

odroider

Hi Frank,

Oh! Great to hear the news about the 0.4 release.

Does the local browser support the multi-touch event?
I am developing a HDMI 7-inch screen with a capacitive touch screen to support the pinch-zoom feature on ODROID-C1+.

hondagx35

Hi odroider,

Does the local browser support the multi-touch event?

No, we are using midori and matchbox-window-manger.
As usual our main goal is to have a responsive and lightweight solution, with one main goal = sound quality.

Frank

odroider

hondagx35 wroteone main goal = sound quality.

I fully agree that. It is the main reason why I've used the RuneAudio.

Let's try 320x240 3.2inch LCD.
You can buy it from this link.
http://www.hardkernel.com/main/products/prdt_info.php?g_code=G142060963922

Add below two line in ~/.bash_profile and save it to load the SPI TFT LCD drivers automatically.

modprobe spicc
modprobe fbtft_device name=odroidc_tft32 rotate=270 gpios=reset:116,dc:115 speed=32000000 cs=0

Orginally I tried to add the drivers into /etc/modules-load.d/odroid.conf, it didn't work correctly.

And create a file "/usr/share/X11/xorg.conf.d/99-odroidc-tftlcd.conf" and paste below configuration to display the X11 on the TFT.

Section "Device"
    Identifier    "C1 fbdev"
    Driver        "fbdev"
    Option        "fbdev" "/dev/fb2"
EndSection

Save it and reboot, you can see the RuneAudio on the 3.2inch LCD.

Time to calibrate the resistive touch screen. Install the calibrator.

pacman -S xinput_calibrator

Run "DISPLAY=:0.0 xinput_calibrator" on the remote shell and follow the instructions.
then, you will get something on the LCD. Follow the instruction on the LCD screen.
You need to use a touch pen and you will have a set of calibration data from the remote console.

[root@runeaudio rules.d]# DISPLAY=:0.0 xinput_calibrator          
        Setting calibration data: 0, 8000, 0, 4800
Calibrating EVDEV driver for "ADS7846 Touchscreen" id=8
        current calibration values (from XInput): min_x=0, max_x=8000 and min_y=0, max_y=4800

Doing dynamic recalibration:
        Setting calibration data: 208, 3842, 3922, 148
        --> Making the calibration permanent <--
  copy the snippet below into '/etc/X11/xorg.conf.d/99-calibration.conf' (/usr/share/X11/xorg.conf.d/ in some distro's)
Section "InputClass"
        Identifier      "calibration"
        MatchProduct    "ADS7846 Touchscreen"
        Option  "Calibration"   "208 3842 3922 148"
        Option  "SwapAxes"      "0"
EndSection

Run "nano /etc/X11/xorg.conf.d/99-calibration.conf" put the section and save it.

Section "InputClass"
        Identifier      "calibration"
        MatchProduct    "ADS7846 Touchscreen"
        Option  "Calibration"   "208 3842 3922 148"
        Option  "SwapAxes"      "0"
EndSection

Now you can control the RuneAudio GUI on the 3.2inch TFT LCD with the touch screen.

Hi !

I have try your instruction to use my C1+ as a standalone.
But i don't have anything in the hdmi output... I try to configure /boot/boot.ini to 1080p but nothing.
I can't start server x by startx or startlxde or lxdm

any idea ?

You can see a login screen on the HDMI monitor without any modification on the official RuneAudio OS image.
Check your HDMI cable or connection first.

ak37

No I see nothing on the monitor... I have tried with Philips TV, samsung PC monitor and sainsmart 7" TFT monitor but same issue!
Cable and all monitors work with my PC and my Udoo

odroider

Could you access the C1+ via SSH when it booted with RuneAudio OS?
