@ -3,13 +3,7 @@ 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/S6D1121/gdisp_lld.mk
