U8GLIB
http://code.google.com/p/u8glib/
Install instructions for the Arduino environment.
1. Unzip u8glib_arduino_vX.XX.zip into the "libraries" folder
2. Start Arduino IDE
Install instructions for the Chipkit (Arduino) environment.
1. cd <mpide-... path>/libraries
2. unzip u8glib_arduino_vX.XX.zip
3. cd <mpide-... path>///hardware/pic32/libraries
4. again: u8glib_arduino_vX.XX.zip
5. Open hardware/pic32/cores/pic32/Print.h
Remove line
#define BYTE 0
from the file, use PRINT_BYTE instead of BYTE.

Note:
UNIX_MAIN --> unix console executable
Current Rule Limitation
- no minor promotion, only "Queening" of the pawn
- threefold repetition is not detected (same board situation appears three times)
Note: Could be implemented, but requires tracking of the complete game
- Fifty-move rule is not checked (no pawn move, no capture within last 50 moves)
Words
Ply a half move

cu_ Chess utility function
stack_ Internal function for stack handling
Issues
10.01.2011
- castling to the right does not move the rook
--> done
- castling to the left: King can only move two squares
--> done
11.01.2011
Next Steps:
- replace stack_NextCurrentPos with cu_NextPos, cleanup code according to the loop variable
--> done
- Castling: Need to check for fields under attack
--> done
- Check for WIN / LOOSE situation, perhaps call ce_Eval() once on the top-level board setup
just after the real move
- cleanup cu_Move
--> almost done
- add some heuristics to the eval procedure
- add right side menu
--> done
- clean up chess_ManualMove
--> done
- finish menu (consider is_game_end, undo move)
- end condition: if KING is under attack and if KING can not move to a field which is under attack...
then the game is lost. What will be returned by the Eval procedure? is it -INF?
--> finished
- reduce the use of variable color, all should be reduced to board_orientation and ply&1
- chess_GetNextMarked shoud make use of cu_NextPos
--> done
- chess_ManualMove: again cleanup, solve draw issue (KING is not in check and no legal moves are available)
--> done
22.01.2011
- simplify eval_t ce_Eval(void)
- position eval does not work, still moves side pawn :-(
maybe because all pieces are considered
--> done

note on __attribute__ ((nocommon))
AVR scripts often use --gc-sections on the linker to remove unused section.
This works fine for initialed data and text sections. In principle .bss is also
handled, but the name##_pb definition is not removed. Reason is, that
array definitions are placed in the COMMON section, by default
The attribute "nocommon" removes this automatic assignment to the
COMMON section and directly puts it into .bss. As a result, if more
than one buffer is defined in one file, then it will be removed with --gc-sections
.. not sure if Arduino IDE uses -fno-common... if yes, then the attribute is
redundant.

Notes
This is one of the most critical parts of u8glib. It must be fast, but still reliable.
Based on the intersection program (see tools folder), there is minimized version of
the condition for the intersaction test:
minimized version
---1----0 1 b1 <= a2 && b1 > b2
-----1--0 1 b2 >= a1 && b1 > b2
---1-1--- 1 b1 <= a2 && b2 >= a1
It includes the assumption, that a1 <= a2 is always true (correct, because
a1, a2 are the page dimensions.
The direct implementation of the above result is done in:
uint8_t u8g_is_intersection_boolean(u8g_uint_t a0, u8g_uint_t a1, u8g_uint_t v0, u8g_uint_t v1)
However, this is slower than a decision tree version:
static uint8_t u8g_is_intersection_decision_tree(u8g_uint_t a0, u8g_uint_t a1, u8g_uint_t v0, u8g_uint_t v1)
Also suprising is, that he the macro implementation is slower than the inlined version.
The decision tree is based on the expansion of the truth table.

Hitachi App Notes:
https://www.sparkfun.com/datasheets/LCD/Monochrome/AN-029-Toshiba_T6963C.pdf
Notes:
The font selection pins should generate the 8x8 font.
For the MGLS240128TZ only FS1 is available on pin 18.
FS1 must be low to generate the 8x8 font.
