This driver is meant to be a light replacement for the stock ones. Programmed in >90% AVR asm, it is faster than the stock drivers. the driver has simple functionality:

  • can clear screen with 565 color format(the LCD color order is strange, not typical 565)
  • can draw "sprites"(rectangles) of different colors

Not working fully yet:

  • diagonal lines are implemented on an unreleased version, but are buggy due to register conflicts between the ino compiled code and the raw asm subroutine
  • 3d wireframe rendering is in the works but requires a trigonometric lookup table, something that must be pre-loaded onto arduino

if anyone wants to experiment, the screen microcontroller seems to allow direct reads/writes to its huge mem pool of around 262kb. Could this be used to supplement the Arduino's measly 2kb? PICTURES COMING SOON
