Hi,
I have tried my LCD module with 8080 16-bit interface to connect to DUE as fallowing, and it worked on with UTFT library.
DB0~DB7 =>Pin 37~Pin 30
DB8~DB15=>Pin 22~Pin 29
Now I have new one with 8080 8-bit interface.
Dose anyone know how to wire those data bus to DUE?
DB0~DB7 => ??
Thanks for help!
Gary
Think about it.
The UTFT 16-bit driver is expecting Adapter shields designed for a Mega.
e.g. VH on PORTA (D22-D29)
and VL on PORTC (D30-D37)
If you plug the shield into a Due, it maps the corresponding pins to the random arrangement of Due Port pins.

Untested. I do not have an 8-bit Mega shield.
Note that the driver code has some conditional code. e.g. if you have a purpose made Due Adapter, you define CTE_DUE_SHIELD or ...
Obviously most UTFT "models" are already set for 16-bit. (in the dtm array)
It would help all the other punters that have bought these 8-bit shields if you report the results.
