File        : LCDDummy.C
Purpose     : Empty driver
              This driver does no perform any function, but it can be
              used for 2 purposes:
              a) Satisfy all externals so an application can be
                compiled and linked in target hardware even if the
                driver is not already available
              b) Template for a starting point for a new driver.
----------------------------------------------------------------------
Adapting to a new system (creating a new driver):
  In this case, the first step is to fill the routines
  LCD_L0_GetPixelIndex, LCD_L0_SetPixelIndex and LCD_L0_Init with
  functionality, which is sufficient to make the hardware work.
  A second (optional) step would be to optimize higher level routines.
----------------------------------------------------------------------
Version-Date---Author-Explanation
----------------------------------------------------------------------
1.00.00 020417 JE     a) Changed to have only to adapt _GetPixelIndex
                         and _SetPixelIndex
0.90.00 020214 JE     a) First release
