HDMI 7inch touch
The 7inch HDMI/USB Display/Touch is now compatible also with UDOO NEO.
By default, UDOO Neo displays the graphical user interface on the micro-HDMI port, but since the micro-HDMI is configured to work with quite all the monitor/TV HDMI, to make this accessories work you need to substitute same files in your UDOObuntu distro.
The 7inch HDMI/USB Display/Touch use:
- HDMI for the Display
- USB-to-microUSB to power up the Display and use the Touch input.
Heads up! You need a micro-HDMI to HDMI
cable or adapter to use the 7inch HDMI display.
Preparation (optional)
To support the 7inch HDMI/USB Display/Touch you need to use a file that set the proper resolution, timing and other parameters for this display.
This new file will disable the original UDOObuntu file that supports default TV/monitor displays.
We suggest making a backup of all the hdmi
related files in the /boot/dts
directory.
for f in /boot/dts/imx6sx-udoo-neo-*hdmi*.dtb; do cp -- "$f" "$f".bak; done
If you want to come back work with a standard TV/monitor you need to revert these files.
