Trying to understand touchscreen compatibility or setup.

[lloydhussell]

Hello. I have been using the VU5 from Odroid up until now where I wanted to explore with some different screens. I've plugged in an Ingcool 7 inch touchscreen, I can't seem to find a model number or anything. It shows everything but I can't touch it like I did with the smaller screen. Is there something I need to setup to make it work, or should it just work out of the box with compatible screens? It does say this screen is compatible with Jetson nano and Pi.

Thanks for any help.

It depends on a driver which may not be installed or potentially doesn't recognize the device.

So I need to install a driver on the Odroid to handle the monitor?

Yes, you need to find out what the USB controller of the touchscreen part of the display is.

The driver exists or it wouldn't work with Linux on other SBCs

Show us "lsusb" output on the command line to find a possible solution.
BTW, which OS image do you run on your N2+?

I am using Mac, so I had to use the alternative lib that someone created.
The driver seems to be "D-WAV SCIENTIFIC CO., LTD. WS170120 Serial: 210719"

I'm also using Android 9 build provided by hardkernel.

Okay, I turned the vu7 setting in both env.ini and boot.ini to true and now it's working.
