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_example.h or gdisp_lld_board_fsmc.h file as a basis. Currently known boards are: BOARD_FIREBULL_STM32_F103 - GPIO interface: requires GDISP_CMD_PORT and GDISP_DATA_PORT to be defined 2. To your makefile add the following lines: include $(GFXLIB)/drivers/gdisp/ILI9481/gdisp_lld.mk
