15 File : LCD159A.C
16 Purpose : Driver for LCDs using a Seiko Epson SED159A controller
17 ----------------------------------------------------------------------
18 Version-Date---Author-Explanation
19 ----------------------------------------------------------------------
20 1.00b 020204 JE a) Hardwareinterface routines renamed:
21 ...DATA -> ...A1, ...CMD -> ...A0
22 1.00a 010926 JE a) Support for LCD_SWAPXY added
23 1.00.00 010710 JE a) Speed optimizations added
24 0.90.00 010709 JE a) First release
25 ---------------------------LIST OF CONFIG SWITCHES--------------------
26 The following is a list of additional configuration switches for this
27 driver. These switches might not be listed in the manual, because
28 the manual mainly covers the general config switches which are
29 supported by all drivers.
30 ----------------------------------------------------------------------
31 define ----------------------Explanation------------------------------
32 LCD_OPTIMIZE Controls the use of optimized routines.
33 If 1, several (speed) optimizations are used.
34 Default: ON (1)
35 ----------------------------------------------------------------------
36 Known problems or limitations with current version
37 ----------------------------------------------------------------------
38 a) Cache not supported yet, becuse RAM requirement would be
39 to large. LCD_CACHE must be set to 0
40 ----------------------------------------------------------------------
41 Open issues
42 ----------------------------------------------------------------------
43 none
