I would like introduce the 'PiChess' (http://www.pichess.org) project. The goal the this project is to create a dedicated chess computer based on the Raspberry Pi (http://www.raspberrypi.org/), the Stockfish chess engine, the DGT eboard en DGT XL Clock (http://www.dgtprojects.com/), and the dgtnix driver (http://dgtnix.sourceforge.net/).
Status
You can see a video here : http://www.dailymotion.com/video/xt2eul_pichess_tech
The inital proof of concept is working on a standard Linux PC, but there is a nasty bug in the Raspberry Pi USB firmware causing the device to hang (http://www.raspberrypi.org/phpBB3/viewt ... 0&p=158380). I hope this will be solved in few weeks
Done so far :
-Added DGT XL clock message display to dgtnix driver
-Added DGT board/clock support to Stockfish
Playing strength
This will be one of the strongest dedicated chess computer on the world My initial testing on Rasperry Pi hardware versus a 4 core Intel i7 shows we have grandmaster strength (http://lefounumerique.xooit.com/t1202-S ... rry-Pi.htm)
Engine Score St
1: Stockfish on Pi 40,0/100 ····················
2: Komodo3-64-sse 20,0/20 11111111111111111111
3: Pharaon 14,0/20 =1=1=101=110==110111
4: AnMon 5.75 11,0/20 ==1=1110=010==011001
5: SOS 5.1 for Arena 10,5/20 10001=10100111=001=1
6: Gaia64 4,5/20 00100100010=00000100
100 games played / Tournament is finished - Level: Blitz 2/1 - Hardware: Intel(R) Core(TM) i5-2405S CPU @ 2.50GHz with 8,0 GB Memory
TODO
Add opening books, and allow opening book selection
Save games to PGN on the SD Card
Add more time controls, and display remaining time on the clock
Allow to takeback moves
Analysis mode
Help needed : SD card packaging
I would like to provide a Raspbian based sd card image that loads stockfish at boot time.
Help needed : logo / documentation
If you have some graphic/english skills, I would like to provide a simple PDF sheet that explains how to use the board and the config modes.

Re: Raspberry Pi / Stockfish dedicated chess computer/board
I'd like to help.
I have a RPi and will be getting another one soon.
Perhaps I could document how to get SF running on two Pi's?

Re: Raspberry Pi / Stockfish dedicated chess computer/board
Hello Matthew,
I did my PC vs Raspberry Pi tournament with Arena, using this method : http://www.playwitharena.com/?Tips_%2B_ ... and_Arena.
You should be able to setup Pi vs Pi matches like this using the Arena GUI.
But I can't see how you would like to use two Raspberry Pi with just one DGT board ?

Re: Raspberry Pi / Stockfish dedicated chess computer/board
I have seen you have recently forked SF:
https://github.com/jromang/Stockfish/tree/dgt
This is one of the reasons I uploaded dev branch on github: I really like and support this (new) way of developing.
Have fun and good luck with your amazing project

Re: Raspberry Pi / Stockfish dedicated chess computer/board
Thank you I'm really impressed by Stockfish's strength on this little piece of hardware !
I also discovered GIT two weeks ago thanks to tour repository I really like the way forked projects can be easily updated to follow the upstream project latest version.

Re: Raspberry Pi / Stockfish dedicated chess computer/board
This looks really great.
What would be fantastic is if someone developed something like a Chess Machine Card which could slot into a PCI port and be run as a USB engine alngside other programs.
It would be like upgrading your P.C!

Code: Select all
Instead of:
string positionFEN = pos.to_fen();
positionFEN = positionFEN.substr(0, positionFEN.find(' '));
//cout << "Compare " << positionFEN << " with "<<fen << endl;
if(!positionFEN.compare(fen)) return ml.move();
perhaps you can write
if (pos.to_fen().find(fen) != string::npos)
return ml.move();

Re: Raspberry Pi / Stockfish dedicated chess computer/board
Yes, that's much better than my code
Thanks for the tip !

Re: Raspberry Pi / Stockfish dedicated chess computer/board
You could also consider using a different USB-serial converter. FTDI is primarily a Windows company and their Linux/Mac drivers and support are horrible.j_romang wrote:...but there is a nasty bug in the Raspberry Pi USB firmware causing the device to hang (http://www.raspberrypi.org/phpBB3/viewt ... 0&p=158380).

Re: Raspberry Pi / Stockfish dedicated chess computer/board
Unfortunately, I can't change the FTDI controller in the DGT board with my soldering skills And this controller works well with an x86 PC and Linux...so the problem really comes from the Raspberry Pi.
If the firmware/hardware issue isn't solved, I will port this project to a 802MK II USB microPC (http://laptoptabletpc.co.uk/rikomagic-8 ... b-micropc/).
