Hi all,
I have been playing with a NanoPi Neo and the 2.8" screen with toutchscreen also from friendly Arm on Linux nanopineo 4.11.0-sun8i.
Making it work was not very easy since it was the first time I messed with device trees, also add to rewire the screen to use a different pin for the touchscreen chip select since the connector is a column bigger that the neo's. I can provide more information or the dts file if it is of interest to someone.
TL:DR:
The problem is that the toutchscreen accuracy is not so great especially on the top part of the screen. I see that the ads7846 driver which I'm using has a "model" option which by being set to "ads7843" handles stuff a bit different. But how the I pass the model to the driver? "model" has no device tree binding, should I use modprobe? Can someone explain the interaction between device trees and modprobe?
Thanks
