To guys who are using libraries with this LCD and getting compiler error:
you must define DOGS102 LCD in dogm128.h file as shown below
//#define DOGM128_HW /* uncomment for the DOGM128 display */
#define DOGS102_HW /* uncomment for the DOGS102 display */
//#define DOGM132_HW /* uncomment for the DOGM132 display */
This shield now can be used with Mega2560 and upcoming DOGM library release (1.11)
Software SPI used to control display since Mega board SPI pins don't match smaller boards this dispaly designed for.
