VU7 Tablet Kit Tutorial

PROJECT: ODROID-C1+ Tablet Kit

PROJECT: ODROID-C1+ Basic Tablet

This 7-inch multi-touch screen for ODROID and other systems (capable of outputting 1024x600 resolution) gives users the ability to create all-in-one, integrated projects such as tablets, game consoles, infotainment systems and embedded systems. The 1024x600 display connects via an HDMI link board or cable (both included) and a microUSB link board or cable (both included) which handles power and signal. Power is supplied through the microUSB jack. This high-quality touchscreen is specifically designed to work with both Android and Linux on the ODROID-C0/C1+/C2 and XU4 with the latest OS updates, but should work with any system capable of outputting at 1024x600 resolution and with a suitable touchscreen driver.

NOTES
  • ALL MODELS: If selecting the ameriDroid Tablet Case Kit add-on to this display, please check the details at http://ameridroid.com/products/ameridroid-vu7-tablet-kit
  • ALL MODELS LINUX: Chromium browser supports multi-touch pinch/zoom.
  • ALL MODELS: During both the boot and power down process, the screen may show digital "noise" due to the lack of an off-sync filter circuit on the screen's controller board.
  • ALL MODELS: The backlight control is not addressable via software, but there is a hardware slide switch.
  • ALL MODELS ANDROID: Please check the wiki pages at http://odroid.com/dokuwiki/doku.php for the Android releases. The first boot of Android will automatically generate the boot.ini file. Insert the boot media into another computer to edit the boot.ini file with the appropriate settings for the VU7-Plus.
  • ODROID-C0/C1/C1+ ANDROID: To use the touchscreen on Android on the C0/C1/C1+, use Android version 2.4 or higher.
  • ODROID-C2 ANDROID: To use the touchscreen on Android on the C2, use Android version 1.2 or higher.
  • ODROID-C0/C1/C1+: There may be an after-image or noise after the system turns off. If this is an issue, de-solder resistor R94 from the circuit board. See additional note under "KNOWN ISSUES" below.
  • ODROID-C0/C1/C1+: The touchscreen driver supports 5 touch points, and proper drivers are integrated into the latest Ubuntu and Android OS images. Check the kernel version of the unit with
uname -a

to verify that it is 3.10.80-128 or higher. If not, please run

sudo apt-get update && sudo apt-get dist-upgrade

The screen resolution must be configured to 1024x600 and the DVI option should be enabled on the "vout" parameter by editing the boot.ini file, with the only two uncommented lines being 

setenv m "1024x600p60hz"
setenv vout_mode "dvi"
  • ODROID-XU3/XU4 ANDROID: To use the VU7-Plus and touchscreen on the XU3/XU4, use Android version 3.5 or higher.
  • ODROID-XU3/XU4: The HDMI timing generator in the Exynos platform is not flexible, so Hardkernel created a modified version of 1024x600 at 54Hz. Check the kernel version of the unit with
  • uname -a

    to verify that it is 3.10.92-63 or higher. If not, please run

    sudo apt-get update && sudo apt-get dist-upgrade

    The screen resolution must be configured to 1024x600 and the DVI option should be enabled on the "vout" parameter by editing the boot.ini file, with the only two uncommented lines being 

    setenv videoconfig "drm_kms_helper.edid_firmware=edid/1024x600.bin"
    setenv vout "dvi"
  • RASPBERRY PI: Some units do not seem capable of powering the screen through the USB port directly, even with "usb_max_current=1" in config.txt. In our tests, the screen powers on fine through an external microUSB power supply. A side effect of this is that the screen cannot transmit touch information to the Raspberry Pi as the USB port is taken by a power supply. We built a USB cable that solves this issue by getting extra power from the 2x20 header, allowing the USB on the Pi to connect to the USB on the VU7, but it appears the Pi is missing the touchscreen driver. We found a compatible touchscreen driver for the Pi at https://github.com/derekhe/waveshare-7inch-touchscreen-driver, but our early tests could not get it to work.
  • KNOWN ISSUE: The display shows noise on the screen during both the boot and power-down process because there is no off-sync filter circuit.
  • KNOWN ISSUE: On the C1+, there will be an after-image or noise when the system turns off if you use the OTG port. If this is an issue for your application, desolder resistor R94 from the C1+ PCB. If your C1+ has a PCB revision of 0.4 2015/09/30, no desoldering is necessary. Simply remove the jumper on J8.
  • KNOWN ISSUE: There is no backlight control except for the slide switch, so software can't adjust the brightness or turn the backlight on or off. However, there is an article in the March 2016 issue of ODROID Magazine showing how to modify the VU7 (identical for the VU7-Plus) to allow software control of on/off and brightness here: http://magazine.odroid.com/wp-content/uploads/ODROID-Magazine-201603.pdf#page=6
