+To use this driver:

+

+1. 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) One (only) of:

+		#define GDISP_USE_GPIO

+		#define GDISP_USE_SPI

+		#define GDISP_USE_FSMC

+

+	d) All of the following (with appropriate values):

+		#define GDISP_SCREEN_WIDTH	320

+		#define GDISP_SCREEN_HEIGHT	240

+

+2. To your makefile add the following lines:

+	include $(GFXLIB)/drivers/gdisp/ILI9320/gdisp_lld.mk
