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`
