ODROID C1+ with 7” Touch screen

smallfat

Hi,

I use the following image to set up my system ( ODROID c1+ and ODROID-VU7 7” Touch screen)
http://dn.odroid.com/S805/RuneAudio_7inch_standalone/
It works well.

I buy another 7” Touch screen with higher resolution (1024 x 600) (7inch HDMI LCD (C) Rev2.1)
from WaveShare. ( WaveShare support claim Rev2.1touch screen use standard HID )
I change RuneAudio display resolution to 1024 x 600 at /boot/boot.ini and reboot system.
Display works well but touch screen no function.

To find the vendor ID (VID) and product ID (PID) for touchscreen using lsusb,

Bus 001 Device 002: ID 05e3:0610 Genesys Logic, Inc. 4-port hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 002: ID 0eef:0005 D-WAV Scientific Co., Ltd
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

What I should do to make touch screen works

Thanks

Hi,

I find a guide to fix waveshare-7inch-touchscreen-driver.
https://github.com/derekhe/waveshare-7inch-touchscreen-driver
But it only for raspiberry.
I am new to Linux. May I use same command as follows to install at RuneAudio to fix my problem?

Following are command for raspiberry:

git clone https://github.com/derekhe/waveshare-7inch-touchscreen-driver
cd wavesahre-7inch-touchscreen-driver
chmod +x install.sh
sudo apt-get update
sudo ./install.sh
sudo restart

Hi smallfat,

May I use same command as follows to install at RuneAudio to fix my problem?

No, because this is for raspbian (debian) and not for Arch Linux Arm.

This does not mean that it is not doable:
- install python3 and all the dependencies

(you have to use "pacman -S package_name" instead of "sudo apt-get install package_name")

- modify /boot/config.txt with the content from 7inch.patch
- copy the files

cp touch.py /usr/bin/
cp touch.sh /etc/init.d/

- make them executable

chmod +x /usr/bin/touch.py
chmod +x /etc/init.d/touch.sh

- learn how to start services with systemd

Sorry, but there is no easy way to it.

As I am new to Linux, I cannot follow what you said.
can you show me step by step?

Thanks in advance

Hi smallfat,

can you show me step by step?

Sorry, but i'm very bussy at the moment.
I also think that python is not the right tool for making device drivers.

This should be a better solution.
But without the hardware it is hard to test.

Thanks your prompt reply
I try to study at your direction

Thanks

Hi Frank,

Due to my poor knowledge to Linux, my problem still not fixed.
But I have some findings. I want to find the solution from another approach.

Let me state the case again.

1. ODROID C1+ with ODROID VU7, RuneAudio image downloaded from below
http://dn.odroid.com/S805/RuneAudio_7inch_standalone/
Works fine except there is a error message prompt every time I boot it up.

2. To improve display resolution and viewing angle, I change a higher resolution Waveshare 7" HDMI display.
http://www.waveshare.com/wiki/7inch_HDMI_LCD_(C)

Scenario 1:
With config in 1, just change resolution at boot/boot/ini
Display works fine, touch function not works.

Scenario 2:
Follow instruction mention at ODROID magazine November issue.
Once RuneAudio boot up, display and touch function works fine.
But chromium web browser/RuneUI cannot not startup.

From above scenario, may I conclude that original RuneAudio image/kernal
support this high resolution display and its touch function natively?

Prebuild image should install a driver to support ODROID VU7.
May I disable or uninstall it to make High resolution 7" display works.

Best Regards
Michael

What happened when you ran the Chromium?
What error messages you met?

obee

I dont get any error window/popup. It just no response.

Hi,

Does this solution only works on specific release of Chromium?
