File : LCD07X1.c
Purpose : Driver for LCDs using K70741 controllers or compatible.
----------------------------------------------------------------------
Version-Date---Author-Explanation
----------------------------------------------------------------------
2.00c 020708 JE a) Changed to work with 2bpp DDP bitmaps
2.00b 020204 JE a) Hardwareinterface routines renamed:
...DATA -> ...A1, ...CMD -> ...A0
2.00a 010924 JE a) Bugfixes: LCD_MIRROR_X, LCD_MIRROR_Y
2.00 010402 RS a) LCD_GetDevCaps removed from driver
(now LCD.c)
1.04 000925 RS a) Support for 8bpp DDBs added
1.03 000505 JE a) XOR mode inserted
b) Renamed this file from LCD0711.C -> LCD07X1.C
1.02 000329 RS Clean up
1.01 000329 RS Cache flushing optimized
1.00 000329 RS First official release. Most routine are
optimized, cache control added.
0.00 990118 EZ/RS First release for Motorola Israel only,
not configuarable, not optimized.
---------------------------LIST OF CONFIG SWITCHES--------------------
The following is a list of additional configuration switches for this
driver. These switches might not be listed in the manual, because
the manual mainly covers the general config switches which are
supported by all drivers.
----------------------------------------------------------------------
define ----------------------Explanation------------------------------
LCD_OPTIMIZE Controls the use of optimized routines.
----------------------------------------------------------------------
Known problems or limitations with current version
----------------------------------------------------------------------
a) LCD_MIRROR_X,Y can not be used together with LCD_SWAP_XY
