Scrolling 1.8" TFT LCD?

Postby Xenoc » Tue May 22, 2012 10:50 am

Hello,

I have a Adafruit's 1.8" TFT LCD with breakout board (not the Arduino shield) that I have hooked up to the native SPI pins, for the faster writing. I'm wondering if there is any way to scroll this display, short of re-drawing everything at a different position (which, even with the faster writing, is still pretty slow). Even if it's not supported by the Adafruit GFX library, does anyone know if it's possible with the display driver chip? Is there some way to maybe tell it to shift display vs memory address mapping or something? Would that work in landscape orientation, or is the row/column orientation wrong for that?

What I basically want to do is make a primitive side-scrolling game.

The data sheet is not entirely clear, but you may be able to side-scroll by changing either the Column Address pointer (or Row Address Pointer - depending on screen orientation).

Look for CASET and RASET in the data sheet, and see what you think:
