Add in your halconf.h: a) #define GFX_USE_GDISP TRUE b) Any optional high level driver defines (see gdisp.h) eg: GDISP_NEED_MULTITHREAD c) If you are not using a known board then create a gdisp_lld_board.h file and ensure it is on your include path. Use the gdisp_lld_board_embest_dmstf4bb_fsmc.h or gdisp_lld_board_embest_dmstf4bb_fsmc.h file as a basis. Currently known boards are: BOARD_EMBEST_DMSTF4BB - GPIO interface BOARD_EMBEST_DMSTF4BB_FSMC - FSMC interface d) The following are optional - define them if you are not using the defaults below: #define GDISP_SCREEN_WIDTH 320 #define GDISP_SCREEN_HEIGHT 240 2. To your makefile add the following lines: include $(GFXLIB)/drivers/gdisp/SSD2119/gdisp_lld.mk
