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.

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+.

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.

one 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.

Code: Select all

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.

Code: Select all

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.

Code: Select all

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.

Code: Select all

[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
INFO: width=320, height=240
[root@runeaudio rules.d]# DISPLAY=:0.0 xinput_calibrator
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
INFO: width=320, height=240

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.

Code: Select all

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.

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.

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

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