+@section History
+
+2.1
+- changes to this header
+
+2.2
+- commented out "#define DISPLAY() ((0UL<<24))" as it collides with a define in the Arduino IDE - the whole section of "macros" needs a rework...
+
+3.0
+- renamed from FT800.h to FT8.h
+- changed FT_ prefixes to FT8_
+- switched to standard-C compliant comment-style
+- changed FT81x register definitions from decimal to hex
+- verified all FT81x register definitions
+- moved FT81x registers marked as "reserved" to an #if 0 block
+
+3.1
+- moved several undocumented commands to an #if 0 block
+
+3.2
+- moved CMD_CRC to the block of undocumented commands as well
+
+3.3
+- changed macros BITMAP_LAYOUT_H and BITMAP_SIZE_H as submitted to github by "jventerprises"
+ These macros provide the extended bits for bitmaps bigger than 511 pixels, FTDIs original implementation that I used and never touched takes the arguments
+ as already processed and not the original values.
+ Note the one example in "FT81x Series Programmers Guide" Version 1.1 for displaying a 800x480 sized bitmap:
+ dl(BITMAP_SIZE_H(1, 0));
+ dl(BITMAP_SIZE(NEAREST, BORDER, BORDER, 288, 480));
+ Now you can use it like this:
+ EVE_cmd_dl(BITMAP_SIZE_H(800, 480));
+ EVE_cmd_dl(BITMAP_SIZE(NEAREST, BORDER, BORDER, 800, 480));
+
+4.0
+- renamed from FT8.h to EVE.h
+- renamed EVE_81X_ENABLE to FT81X_ENABLE
+- changed FT8_ prefixes to EVE_
+- rearranged things a bit with FT80x specific includes moved to the end and a "#if defined (BT81X_ENABLE)" block on top of the chip-specific includes
+- started to add specific BT81x defines
+- minor maintenance
+- changed OPT_FLASH to EVE_OPT_FLASH and OPT_FORMAT to EVE_OPT_FORMAT for consistency
+- added EVE_OPT_FILL which has been left out of the documentation for the BT81x so far
+- added a few BT81x specific macros
+- added a few FT81x/BT81x specific host commands
+- removed the preceding underscore from the include guard define to avoid potential undefined behavior
+- removed a bunch of defines for FT80x that I never implemented for FT81x
