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 halconf.h:
a) #define GFX_USE_GDISP TRUE
b) Any optional high level driver defines (see gdisp.h) eg: GDISP_NEED_MULTITHREAD
c) All of the following (with appropriate values):
b) #define GFX_USE_TOUCHSCREEN TRUE
c) Any optional high level driver defines (see gdisp.h) eg: GDISP_NEED_MULTITHREAD
d) All of the following (with appropriate values):
#define GDISP_SCREEN_WIDTH 640
#define GDISP_SCREEN_HEIGHT 480
