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
