- ----------------------------------------------------------------------
- File : LCDDummy.C
- Purpose : Empty driver for emWin GSC
- 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
