I have a LCD which is based on the SD1289 controller chip. I see that the UTFT library supports my display in 16 bit parallel mode. In looking at the UTFT requirements doc I see the wiring from the Teensy 3.1 to the LCD connector uses signals on the bottom of the Teensy board which I would rather not do. In fact the wiring between the DBx signals on the display and the Teensy 3.1 seems to jump all over where as I would like to connect pin0 - pin 15 on the Teensy to DB0 - DB15 on the display.
Is there some reason for this? Does the documented arrangement of signals somehow group port pins within the ARM processor together so writes are optimized?
If I sequentially connect up the pins as I mentioned would performance be compromised?
I feel I must be missing something here but don't know what.
Thanks
