Arduino and TFT Display Interface

In this instructable, https://www.instructables.com/id/How-to-Interface-a-4x3-TFT-Display-With-an-Arduino/

(It uses 4x3” TFT LCD from FocusLCDs.com)

I was wondering if it is possible to be rid of the RA8875 driver board and connect it directly to the Arduino.

I'd appreciate some tips.

To drive a TFT in a "raw" fashion requires a much bigger chip than the standard Arduino has... You can implement a raw driver with the Due and it looks pretty good.. You will need a display buffer ( same size of the screen ) 480 x 272 x 2.. About 262 kilo bytes of ram Then at least two timers to create the timing... BUT!! before you start, even high end systems use custom graphic driver chips, it uses far too many resources to run it direct.

If you need pointers look into the microchip LCC driver for the pic32 range... It has been implemented on that platform.
