+ #define LCD_USE_FSMC
+ d) All of the following (with appropriate values):
+ #define SCREEN_WIDTH 320
+ #define SCREEN_HEIGHT 240

+To use this driver:
+
+1. Add in your halconf.h:
+ a) #define HAL_USE_GDISP TRUE
+ b) Any optional high level driver defines (see gdisp.h) eg: GDISP_NEED_MULTITHREAD
+ c) Define these:
+ #define GDISP_VMT_NAME1(x) x##YourDriver1
+ #define GDISP_VMT_NAME2(x) x##YourDriver2
+ Note YourDriver1 & 2 are the basenames of the directories containing the driver.
+ Note that both drivers must be the same pixel format which is
+ GDISP_PIXELFORMAT_RGB565 by default. Alter gdispVMT/gdisp_lld_config.h if your
+ pixel format is different on both drivers.
+ d) Any driver specific defines. If both drivers use the same defines then they must
+ accept the same values for the define.
