What is the recommended peripheral to use when connecting to an OLED (or any) display that uses a 8-bit 6800/8080 parallel bus?  My initial research into the subject seems to imply that you should use the EMC+DMA.  However I'm already using the EMC for external SDRAM.  Is it possible to use the LCD controller for this purpose?  How about the SGPIO+DMA?

So the 3 options that I've identified:

-  Will there be bus contention with external SDRAM?

LCD Controller?
- The LPC43xx manual doesn't mention the 6800/8080 parallel bus at all.


Any advise, reference circuits/code would be greatly appreciated.

Thank you.
