To use this driver: This driver is special in that it implements both the gdisp low level driver and a touchscreen driver. 1. Add in your gfxconf.h: a) #define GFX_USE_GDISP GFXON b) #define GFX_USE_GINPUT GFXON #define GINPUT_USE_MOUSE GFXON c) Any optional high level driver defines (see gdisp.h) eg: GDISP_NEED_MULTITHREAD d) Optionally the following (with appropriate values): #define GDISP_SCREEN_WIDTH 640 #define GDISP_SCREEN_HEIGHT 480 2. To your makefile add the following lines: include $(GFXLIB)/gfx.mk include $(GFXLIB)/drivers/multiple/SDL/gdisp_lld.mk 3. Install sdl2 on Linux: sudo apt-get install libsdl2-dev on OSX: brew install sdl2 --universal 4. Modify your makefile to add `sdl2-config --libs --cflags` to the CFLAGS line. i.e. CFLAGS = `sdl2-config --libs --cflags`
