Protocol description for DGT chess board.

Copyright 1998 DGT Projects B.V

Version: 1.03 Single computer and bus support in one .h file

*********************************************************

This protocol is protected under trade mark registration and copyrights.

It may not be used commercially without written permission

of DGT Projects B.V. It is illegal to transfer any registered trade mark

identifications by means of this protocol between any chessboard or other

application and any computer.

*********************************************************

Main functionality of the DGT Electronic Chess Board

----------------------------------------------------

The DGT board is basically a sensor which senses the presense of the special

chess set pieces on the squares of the board. The situation on the board is

measured and can be communicated with an average maximum time delay of

200 mS.

Besides this detection function, the board communicates with an optional

DGT TopMatch Chess Clock, to give the data of the clock available to the

general interface.

Finally the board is equipped with an internal storage of the measured

piece positions.

The board supports two methods of communication: for single-board situations

a protocol for communication between one board and one computer is available.

For situations with many boards a network communications protocol is

available, where many boards can be connected in a bus structure. A separate

communication protocol is available for this bus structure.

The communication protocol for single board connections is described

in the following paragraph "Single board communication protocol". This

paragraph describes much more than only the communication protocol. All

developers should read this paragraph, even if they would only use bus

communication.

The special bus communication protocol is derived from the single board

communication and functionality, where the main added feature is the

possibility to address a specific board on a shared communication bus.

The commands and data contens are described in the paragraph "Bus

Communication Protocol", Note however that the contens can not be understood

without reading the single board communication paragraph.

Paragraph: Single board communication protocol

----------------------------------------------

The main function of the board is to transfer piece position information.

For this, three modes are available:

1. IDLE mode. This cancelles any of the two UPDATE modes. No automatic

transfer of moves.

2. UPDATE_BOARD mode. On the moment that the board detects a removal, change

or placing of a piece, it outputs a DGT_SEND_UPDATE message

3. UPDATE mode. As UPDATE_BOARD mode, where additional the clock data are send

regularly (at least every second)

The board accepts command codes from the computer RS232. The commands are

1-byte codes, sometimes followed by data (see code definition)

The board can send data to the computer. Data always carries a message header.

The message header contains a message code and the total message size in bytes.

The start of the incoming message can be recognised by the MSB of the message

identifier set to 1 (see definition).

Board to computer communication interfaces:

RS232 for communication with computer, receiving commands, sending data

- 9600 Baud, 1 stopbit, 1 startbit, no parity

- No use of handshaking, neither software nor hardware

Connection between Digital Game Timer TopMatch Clock and the board:

Based on NEC SBI protocol. Adaption of the definition given in

the DGT TopMatch documentation.

Connector assignments for DGT Electronic Board: See User

and Programmers Manual

Related to the before mentioned modes, and to piece position information

transfer, the following commands to the board are available:

1. DGT_SEND_RESET

puts the DGT Board in IDLE mode

2. DGT_SEND_CLK

on which the DGT board responds with a DGT_MSG_BWTIME message containing clock

information

3. DGT_SEND_BRD

on which the DGT Board responds with a DGT_MSG_BOARD_DUMP message containing

the actual piece exising of all fields

4. DGT_SEND_UPDATE puts the DGT Board in the UPDATE mode, FRITZ5 compatible

5. DGT_SEND_UPDATE_BRD puts the DGT Board in the UPDATE_BOARD mode

6. DGT_SEND_UPDATE_NICE puts the board in UPDATE mode, however transferring only clocktimes when any time info changed.

The DGT_SEND_CLK command and the DGT_SEND_BOARD command do not affect the current board

mode: i.e. when in UPDATE mode, it continues sending DGT_SEND_UPDATE messages.

Board Identification:

Each DGT Electronic Board carries a unique serial number,

a EEPROM configuration version number and a embedded program version number.

These data are unalterable by the users.

Current identification is:

"DGT Projects - This DGT board is produced by DGT Projects.\n

DGT Projects is a registered trade mark.\n

220798 ISP/bus/8KP/8KE/P6/Fritz5 Vs 1.00. Serial nr. 00137 1.0"

The board can be loaded by the user with a non-volatile one-byte bus number,

for future use with multiple board configurations.

On-board EEPROM:

The board carries a 8 kB cyclic non-volatile memory, in which all position

changes and clock information is stored during all power-up time. This

file can be read and processed.

byte 3-66: Pieces on position 0-63

Board fields are numbered from 0 to 63, row by row, in normal reading

sequence. When the connector is on the left hand, counting starts at

the top left square. The board itself does not rotate the numbering,

when black instead of white plays with the clock/connector on the left hand.

In non-rotated board use, the field numbering is as follows:

Field A8 is numbered 0

Field B8 is numbered 1

Field C8 is numbered 2

..

Field A7 is numbered 8

..

Field H1 is numbered 63

So the board always numbers the black edge field closest to the connector

as 57.
