Chess Mate

Initially, it should appear "PLAY" at the display

• Press and hold "NEW" + the number of level
• Enter your 4 digit move then press "ENTER"
• Wait for lily thinking (it will be displayed blinking dots)
• The lily move will be displayed just after the thinking
• If you entered an erroneous digit; press "CLR", short press, to delete one digit
• If you want to delete all digits entered, press and hold "CLR"

Here follows a demonstration of Lily chessmate playing against a mobile phone:

Lily won when we were not recording... :~(

After many hours of testing and debugging ...

First Release!

Try yourself to beat Lily.

Enjoy!

Here follows the first game of Lily ChessMate against an Online Chess computer:

[White "Online Chess Computer at 3s per move"]
[Black "Lily - ChessMate at Level 6/8"]

[Result "1-0"]

Online Chess Computer (WHITE) X Lily level 6 (BLACK)

After struggling with a pair of bugs that were caused by the remains of debugging instructions I've managed to put the debouncing/detecting routines to work.

Now I have a global that stores the events related to the keys CLR, ENTER and Kyes 1-8.

// return value in key status: bit  7 6 5 4 3 2 1 0
//                                    | | | | \   /
// CLR long=1/short=0 ----------------+ | | |  \ /
// CLR event----------------------------+ | |   V
// ENTER event----------------------------+ |   |
// Key[1-8] event---------------------------+   |
// Key Pressed (1..8)---------------------------+

And here is a video of the detection working:

Testing the display refresh and debounce routine. So far only the CLR key is being tested whilst the display code is already fully implemented. Notice the fast presses at the final moments of the video. They do not change the display because the short press/noise treshold is 100ms (whilst the long press treshold is 600ms).

Despite the board being designed originally for common cathode displays, after assembly I have found that I made a mistake about the polarity of the LED display @Reinaldo provided. On the lack of another common anode display I have modified the board by using PNP transistors instead of NPN and feeding the emitters with VCC (instead of GND). That was fed back to the design and now the board has a solder jump to allow using either common anode or common cathode displays.

The official name for the project is Chess Mate but it already have a codename: Lily
