David Smart / Mbed OS PUB_RA8875_Tetris

Tetris for the RA8875, derived from another users implementation.

Dependencies:   RA8875

Fork of Tetris by Sergejs Popovs

Tetris, adapted to the RA8875 graphics library and display.

As currently implemented, this version is defined for the 800x480 display. A number of macros can adapt it for other screen resolutions.

Further, while presently configured for landscape mode, it should be fairly easy to reconfigure it for portrait mode.
