Well, we have a lot of work to do yet, and the 7" is only a small part, so we didn't started yet.
The 7" screen is a part of a project we call "workduino" which is a scalable industrial controller half way PLC and CNC. We are designing now the first pcb board. I will open a post if someone is interested in it.
I had a look at the screen and UTFT, and the strange thing for me is that no power is supplied to the background, and all is 3.3v. Don't know if it is normal as I'm used to use alphanumeric and touch screen panels, which uses 5v or 24v.
I will try to find time and post it on projects section.
